    Forecasts for Ireland



    TRENDS for the WEEK of 6 to 12 April ...

    Temperatures will average near normal, around 12 to 14 C on average in the daytime hours.

    Rainfall will average about 5 to 10 mm which is about half the normal amount.

    Sunshine will average about 5 hours a day which is near or slightly above normal.

    Winds will generally be rather light easterly, sometimes moderate.


    FORECASTS

    TODAY ... The overnight rain will continue to drift further west and out to sea this morning, with a slow and gradual clearing trend allowing for some decent sunny breaks by late morning east and early afternoon west. Highs 11 to 14 C in light to moderate easterly breezes. Some isolated showers may follow but these will be widely separated and brief.

    TONIGHT ... Some clear intervals, slight frosts developing, lows -2 to +3 C. Misty or foggy by morning.

    SUNDAY ... Partly cloudy, isolated showers possible, highs 11 to 14 C.

    MONDAY ... Increasing cloud, some outbreaks of light rain in the south mainly, lows near 5 C and highs near 11 C.

    TUESDAY ... Variable cloud, showers then clearing gradually, lows near 6 C and highs near 10 C.

    WEDNESDAY to FRIDAY will see a return to longer sunny intervals and somewhat milder highs near 13 C. Slight frosts are likely.

    FURTHER OUTLOOK ... Rain may set in around Friday night and become heavier by next weekend. Although current guidance favours milder weather holding out for a while, very cool air masses will never be that far away to the north and northeast, probably affecting northern Britain and possibly having some influence on Ulster and north Leinster if not larger portions of the country.

    My local weather on Friday was overcast with light rain, about 2 mm fell and somewhat heavier amounts are likely here this weekend. We could use some rain as the spring blooming is very slow to advance despite milder temperatures this past week. Trees are almost out into full leaf at the coast but no sign of leaf development here at all yet. We are normally a week or two behind but it seems more like a month in this case.

    Forecasts for Ireland



    TRENDS for the WEEK of 7 to 13 April ...

    Temperatures will average near normal, around 12 to 14 C on average in the daytime hours. The regional trend will be somewhat warmer than average in the west to slightly cooler in the east.

    Rainfall will average about 10 to 20 mm which is almost equal to the normal amount. This will include 5 to 15 mm towards the end of the weekly interval.

    Sunshine will average about 4 hours a day which is near or slightly below normal.

    Winds will generally be rather light easterly, sometimes moderate.


    FORECASTS

    TODAY ... After a cold start, mist or fog should dissipate, then warming up gradually under sunny to partly cloudy, isolated showers possible by late in the day in the southeast, with highs 11 to 14 C, warmer away from the east coast.

    TONIGHT ... Partly cloudy to overcast, lows 3 to 7 C. Some light rain by morning in parts of central Leinster.

    MONDAY ... Increasing cloud, some outbreaks of light rain in central counties from east to west, and highs near 11 C with the light rainfall, to 13 C in parts of the south and west.

    TUESDAY ... Variable cloud, showers or light rain, trending further south during the day, then clearing gradually with some sunshine at times inland north and midlands, lows near 6 C and highs 10 to 12 C.

    WEDNESDAY to FRIDAY will see a return to longer sunny intervals and somewhat milder highs near 13 C. Slight frosts are likely.

    FURTHER OUTLOOK ... Rain may set in around Friday night and become heavier by next weekend. Temperatures from Saturday to about Monday 15th will be near 15 C with persistent rain that could become heavy in some places. Beyond that it may become slightly cooler with the risk of a significantly colder interval around Easter.

    My local weather on Saturday was milder with patchy light rain in the area, and a high near 14 C.

    Monday, 8 April, 2019

    Forecasts for Ireland



    TRENDS for the WEEK of 8 to 14 April ...

    Temperatures will average near normal, around 12 to 14 C on average in the daytime hours. The regional trend will be somewhat warmer than average in the west to slightly cooler in the east.

    Rainfall will average about 10 to 15 mm which is almost equal to the normal amount. The heavier rainfall earlier expected to arrive next weekend has been downgraded in amount for the time being to about 5 to 10 mm of this total.

    Sunshine will average about 4 hours a day which is near or slightly below normal.

    Winds will generally be rather light easterly, sometimes moderate.


    FORECASTS

    TODAY ... Mostly cloudy, some outbreaks of light rain in central counties from east to west, and highs near 11 C with the light rainfall, to 13 C in parts of the south and west. Rainfalls 2 to 5 mm where they occur.

    TONIGHT ... Mostly cloudy, some patchy light rain or drizzle, mist or fog developing. Lows 5 to 7 C.

    TUESDAY ... Variable cloud, showers or light rain, trending further south during the day, then clearing gradually with some sunshine at times inland north and midlands, lows near 6 C and highs 10 to 12 C.

    WEDNESDAY and THURSDAY will bring partly cloudy skies, some better sunshine in western counties, and highs ranging from about 11 C in the east to 14 C in the west. Nights will be mostly frost-free except for isolated pockets with clear skies.

    FRIDAY to SUNDAY was looking wet in yesterday's outlook but now it appears that high pressure over Scandinavia will have more influence and may keep most of the moisture near the west coast or even offshore. However, there will be some light patchy rain at times in a strengthening southeast wind flow 40 to 60 km/hr, and temperatures will stay in a similar range (11 to 14 C).

    FURTHER OUTLOOK ... There now seems to be some chance that the high will become more dominant and send a pulse of colder air west to reach Ireland around Monday 15th (after slowly crossing Britain during the weekend of 13th-14th) so that temperatures may fall back to rather low values 7 to 11 C around the start of the following week. No particular warmth appears on maps beyond that either with hints of further cold outbreaks, so the month's best interval may be later this week.

    My local weather on Sunday was mostly cloudy with patchy light rain in the area, not much accumulation, and highs near 12 C.

    Tuesday, 9 April, 2019

    Forecasts for Ireland



    TRENDS for the WEEK AHEAD (9 to 15 April)

    Temperatures will average near normal but that will include some above normal readings around Thursday and Friday and some below normal values this weekend into Monday.

    Rainfall will average 10 to 20 mm, a little below average except for isolated 20 to 30 mm totals in Munster and south Leinster.

    Sunshine will average 2 to 3 hours a day, below normal for mid-April.

    Winds will continue easterly trending more southeasterly by the weekend. They will generally be rather moderate (30 to 50 km/hr).

    =========

    FORECASTS


    TODAY will be mostly cloudy with a few brighter intervals in the north, appearing later in central counties. Widespread fog and mist this morning could be a travel hazard for a while before easing before mid-day. Rain will move slowly west across south Leinster into Munster and some places could see 20 mm but amounts further north in isolated showery outbreaks will be only 1 or 2 mm. Highs near 14 C in western coastal regions, to 10 C near east coast and in the wetter south. Moderate east winds at times 40 to 60 km/hr.

    TONIGHT will continue rather hazy to foggy as the last of the rain moves out to the Atlantic, and lows will be 5 to 8 C. Some dense fog patches may redevelop.

    WEDNESDAY will be partly cloudy with longer sunny intervals in some western counties. It will be a bit warmer in general, highs 12 to 16 C.

    THURSDAY will also be partly cloudy and warm (cooled somewhat near east coast), lows near 4 C and highs near 16 C.

    FRIDAY will bring intervals of cloud and sunshine and more of a southeast breeze, still about the same temperatures, lows near 4 C and highs near 15 C.

    WEEKEND OUTLOOK ... Partly to mostly cloudy, brisk southeast winds, somewhat colder especially in south Leinster and east Munster, and risk of some outbreaks of light rain mainly in the east and south. Highs will be in the range of 8 to 12 C.

    FURTHER OUTLOOK ... Occasional rain, temperatures rising gradually back to mid-teens at some point next week, then risk of another colder spell developing around Easter.

    My local weather on Monday was sunny at first, then overcast later, but dry and rather cool with highs near 9 C.

    Wednesday, 10 April, 2019

    Forecasts for Ireland



    TRENDS for the WEEK AHEAD (10 to 16 April)

    Temperatures will average near normal but that will include some above normal readings around Thursday and Friday and some below normal values this weekend into Monday.

    Rainfall will average 10 to 20 mm, a little below average except for isolated 20 to 30 mm totals in west Munster and Connacht.

    Sunshine will average 2 to 4 hours a day, below normal for mid-April although closer to normal in parts of the north.

    Winds will continue easterly trending more southeasterly by the weekend. They will generally be rather moderate (30 to 50 km/hr) but will increase to blustery southeast to south especially near coasts at times this weekend (50 to 70 km/hr).

    =========

    FORECASTS


    TODAY will be partly cloudy with longer sunny intervals in some western counties. It will be a bit warmer in general, highs 12 to 16 C.

    TONIGHT will stay partly cloudy with clear intervals leading to some fog and mist by dawn. Lows -1 to +5 C mildest in south coast districts and colder inland north and midlands.

    THURSDAY will also be partly cloudy and warm (cooled somewhat near east coast), with highs near 16 C.

    FRIDAY will bring intervals of cloud and sunshine and more of a southeast breeze, still about the same temperatures, lows near 4 C and highs near 15 C.

    WEEKEND OUTLOOK ... Partly to mostly cloudy, brisk southeast winds, somewhat colder especially in south Leinster and east Munster, and risk of some outbreaks of light rain mainly in the south at first, then near west coast by late Saturday into Sunday. Some of this rain could become heavy near outer coastal districts but may not make much progress east as weather systems grind to a halt. Highs will be in the range of 8 to 12 C. Winds southeast 50 to 70 km/hr. The western cloud and rain will make one brief push eastward by Monday then the frontal band should weaken quickly into Tuesday, the result will be sporadic outbreaks of light rain then slow clearing.

    FURTHER OUTLOOK ... Occasional rain, temperatures rising gradually back to mid-teens at some point next week, then risk of another colder spell developing around Easter. Highs could reach 15 or 16 C around mid-week (17th) then may fall back somewhat into the Easter weekend.

    The flow will remain easterly much of the time.

    My local weather on Tuesday was overcast and rather chilly all day with highs near 8 C. A major snowstorm is developing overnight near Denver Colorado and will spread very strong winds and snow into the north central plains states. Nebraska and South Dakota will see blizzard conditions and Kansas, eastern Colorado and eventually Oklahoma and parts of Texas will have very strong northerly winds. This storm will begin to weaken when it reaches Minnesota on Friday. But by then there could be a fairly severe outbreak of thunderstorms in the Midwest on Thursday. Effects on the east coast will be indirect, mainly to promote a warmer interval of southerly winds later this week.

    Thursday, 11 April, 2019

    Forecasts for Ireland




    TRENDS for the WEEK AHEAD (11 to 17 April)

    Temperatures will average about 1 degree below normal with a cooling trend setting in around Saturday. Temperatures will recover back towards normal values towards the end of the period.

    Rainfall will average 10 to 20 mm, a little below average except for isolated 20 to 30 mm totals in west Munster and Connacht.

    Sunshine will average 2 to 4 hours a day, below normal for mid-April although closer to normal in parts of the north.

    Winds will continue easterly trending more southeasterly by the weekend. They will generally be rather moderate (30 to 50 km/hr) but will increase to blustery southeast to south especially near coasts at times this weekend (50 to 70 km/hr).

    =========

    FORECASTS


    TODAY will be partly cloudy and quite warm except cooled by sea breezes somewhat near east coast, with highs near 15 C in the west, 12 to 14 C midlands and south, 10 to 12 C east and north.

    TONIGHT will bring a few clear intervals then increasing cloud later, lows -1 to +4 C.

    FRIDAY will bring intervals of cloud and sunshine and more of a southeast breeze, temperatures similar in all regions to today's readings, with highs 10 to 15 C.

    WEEKEND OUTLOOK ... Partly to mostly cloudy, brisk southeast winds, somewhat colder especially in south Leinster and east Munster, and risk of some outbreaks of light rain mainly in the south at first, then near west coast by late Saturday into Sunday. Some of this rain could become heavy near outer coastal districts but may not make much progress east as weather systems grind to a halt. Highs will be in the range of 8 to 12 C. Winds southeast 50 to 70 km/hr. The western cloud and rain will make one brief push eastward by Monday then the frontal band should weaken quickly into Tuesday, the result will be sporadic outbreaks of light rain then slow clearing.

    FURTHER OUTLOOK ... Occasional rain, temperatures rising gradually back to mid-teens at some point next week, then risk of another colder spell developing around Easter. Highs could reach 15 or 16 C around mid-week (17th) then may fall back somewhat into the Easter weekend.

    The flow will remain easterly much of the time.

    My local weather on Wednesday was mostly cloudy and cool with highs near 9 C. There was rain falling almost all day a few miles to our south and west but it stayed dry here anyway. Gusty winds at times from these nearby showers. The wind and snow predicted moved into the plains states and severe weather is likely in the Midwest later today. At one point it was 32 C in Oklahoma and -8 C in Denver with blowing snow.

    Friday, 12 April, 2019

    Forecasts for Ireland



    TRENDS for the WEEK AHEAD (12 to 18 April)

    -- Temperatures will average slightly below normal values, days mostly in the 10 to 13 C range.

    -- Rainfall will vary from rather light in the east (5-10 mm) to heavy in the southwest (40-70 mm) with Sunday-Monday the wettest days.

    -- Sunshine will average only 2 hours a day in the west, to a more normal 4-5 hours in Leinster.

    -- Winds will become stronger than recent days, from a southeast direction mainly.


    FORECASTS


    TODAY ... Cloudy with brighter intervals for west and south, partly cloudy to sunny at times in east and north, rather cool southeasterly winds developing, isolated light showers in west Munster and Connacht. Highs 10 to 13 C.

    TONIGHT ... Partly cloudy, breezy, lows 2 to 6 C.

    SATURDAY ... Increasing cloud, brisk and rather cold southeast winds 50 to 70 km/hr. Highs 8 to 11 C.

    SUNDAY ... Outbreaks of rain may become rather heavy from early morning onwards in western counties with potential for 15-30 mm. This rain will not extend all the way across the country and the cut-off is likely to be in the midlands. Brisk southeast winds, highs 8 to 12 C.

    MONDAY ... Rain continuing rather heavy in parts of Munster and Connacht, light and sporadic further east and in most of Ulster. Highs around 12 to 14 C.

    TUESDAY ... Partly cloudy, showers, somewhat warmer with highs 14 to 16 C.

    OUTLOOK ... Continued east to southeast winds will bring alternating pulses of mild and chilly days for the rest of the week, but at the moment it appears possible that the Easter weekend will coincide with a warmer interval around 15 C.

    My local weather on Thursday was overcast with showers nearby again, and once again very little rain at my location. The high was about 12 degrees C. The blizzard-like storm further east in the northern plains states brought dangerous conditions to parts of South Dakota and western Minnesota but the storm will now ease off as it tracks further east.

    Saturday, 13 April, 2019

    Forecasts for Ireland


    TRENDS for the WEEK AHEAD (13 to 19 April)

    -- Temperatures will average near normal values, cooler at first then a bit warmer than normal later next week, as highs work their way up from 8-11 to 15-18 C.

    -- Rainfall will vary from near average in the east (15-20 mm) to heavy in the southwest (40-70 mm) with Sunday-Monday the wettest days.

    -- Sunshine will average only 2 hours a day in the west, to a more normal 4-5 hours in Leinster. The average will be improving through the second part of the week.

    -- Winds will become stronger than recent days, from a southeast direction mainly.


    FORECASTS


    TODAY ... Increasing cloud, brisk and rather cold southeast winds 50 to 70 km/hr. Highs 8 to 11 C. Rain will be edging into the west by afternoon and will become rather heavy by evening there. It should stay mostly dry east of about a Roscommon to Waterford line.

    TONIGHT ... Rain will continue to edge further east, with heavy bursts leading to 10-20 mm likely in the western and later some central counties. Lows 7-9 C. Much less rain likely near east coast although some drizzle or light rain by morning even there.

    SUNDAY ... Outbreaks of rain may become rather heavy from early morning onwards in western and some central counties with potential for 15-30 mm. This heavier rain will not extend all the way across the country with smaller amounts expected in coastal Leinster where 2 to 7 mm will be the most likely range. Brisk southeast winds, highs 8 to 12 C. Some fog likely in areas with heavier rainfall.

    MONDAY ... Rain continuing rather heavy in parts of Munster and Connacht, light and sporadic further east and in most of Ulster. Highs around 12 to 14 C. Foggy or misty at times.

    TUESDAY ... Partly cloudy, showers, somewhat warmer with highs 14 to 16 C. Longer sunny intervals by afternoon.

    WEDNESDAY to FRIDAY ... Partly cloudy to sunny, rather chilly nights with frosts in some places, but gradually warming in the daytime hours to highs of 16 to 18 C.

    FURTHER OUTLOOK ... The Easter weekend at this point looks quite pleasant with the relatively warm weather expected to continue until about Easter Monday. Beyond that, rather uncertain with forecast models changing from run to run, would at least expect an increasing chance of cloud and rain and possibly a bit colder too.

    My local weather on Friday was partly cloudy with some sunshine at times, highs around 14 C.

    Sunday, 14 April, 2019

    Forecasts for Ireland



    TRENDS for the WEEK AHEAD (14 to 20 April)

    -- Temperatures will average 1 to 2 degrees above normal values, even though today will be several degrees below average -- it will steadily warm up from Monday to Thursday and become quite warm on the Easter weekend.

    -- Rainfall will vary from near average in the east (15-20 mm) to heavy in the southwest (40-70 mm) with Sunday-Monday the wettest days.

    -- Sunshine will average about 4 hours a day and since the first two days of the interval will be mostly cloudy, that implies an average of 6 or 7 hours starting around Tuesday.

    -- Winds will peak at very strong on Monday especially in western counties, then from Tuesday to the end of the interval, mostly moderate southerly.


    FORECASTS


    TODAY ... Outbreaks of rain will ease off to drizzle by afternoon, before a second pulse of heavier rain arrives this evening. The extent of any rain into east coast counties may be hit or miss with some places remaining dry at least for most of the time. Moderate to strong southeast winds 60 to 100 km/hr in exposed locations will add some chill and highs will only reach about 8 to 10 C at best, except 10 to 13 C in parts of Kerry and Cork.

    TONIGHT ... Rain becoming heavy again with the risk of thunderstorms in parts of Munster. Some heavier rain may develop for a time in the southeast and move up the east coast, but possibly easing before reaching Dublin and north Leinster. Amounts will be 30 to 50 mm in some parts of the south and west, trending steadily downward to 10 mm in parts of the northeast. Lows about 6 C with winds continuing moderate to strong southeast 60 to 100 km/hr.

    MONDAY ... Rain continuing rather heavy in parts of Munster and Connacht, light and sporadic further east and in most of Ulster. Highs around 12 to 14 C. Foggy or misty at times. Winds southeast to south 70 to 110 km/hr in west Munster and later in Connacht, and some exposed parts of east Munster and south Leinster, otherwise about 50 to 80 km/hr further north and inland. Strong winds may continue most of Monday night slowly veering to southwest then easing by Tuesday morning.

    TUESDAY ... Partly cloudy, showers, somewhat warmer with highs 14 to 16 C. Longer sunny intervals by afternoon. Winds moderate southwest backing to southerly 40 to 70 km/hr.

    WEDNESDAY to FRIDAY ... Partly cloudy to sunny, rather chilly nights with frosts in some places, but gradually warming in the daytime hours to highs of 16 to 18 C and locally 18 to 20 in midlands and western counties by Good Friday.

    FURTHER OUTLOOK ... The Easter weekend at this point looks quite pleasant with the warmer weather expected to continue until about Easter Monday. Beyond that, rather uncertain with forecast models changing from run to run, would at least expect an increasing chance of cloud and rain and possibly a bit colder too.

    My local weather was cool and wet with a low cloud ceiling most of the day and highs only about 7 C. For the Masters golf tournament, the tee times have been moved forward as organizers race to get the final round completed before a strong line of storms is expected to arrive by mid-afternoon local time. This front caused severe storms in Texas, Louisiana and Mississippi on Saturday and threatens to do the same in Georgia and South Carolina today. Currently the storms are moving through Alabama but as it is early morning they have dropped below tornadic levels to heavy thunderstorms at this point. Even before this line of storms reaches eastern Georgia, the golf may be delayed at times by weaker passing thunderstorms. Otherwise it will be warm and humid with southerly winds and highs near 27 C there.

    Monday, 15 April, 2019

    Forecasts for Ireland



    TRENDS for week of 15 to 21 April

    Temperatures will average about 2 degrees above normal with a gradual increase through the period, ending up near 4 degrees above normal in some parts of the west, midlands and inland south by the Easter weekend.

    Rainfall will amount to a normal week's worth for most, or a little more, but almost all of that will fall today, so the trend after today is dry.

    Sunshine will increase through the week and should average 6 to 8 hours a day overall, up to 50% above normal (but today will be mostly cloudy).

    Winds will moderate after today and become rather light by the warmer spell expected later in the week.


    FORECASTS


    TODAY ... Rain continuing rather heavy and spreading north through Leinster and the midlands towards Ulster, 15 to 25 mm likely in this first wave. A second batch of moderate to heavy rain is likely to hit the south coast by mid-day and this will track up the west coast with some heavy amounts locally into western Galway and Mayo by afternoon. This rainfall will also total about 15 to 25 mm with some heavier amounts possible in hilly areas of the south and west. A few places may escape both of these waves but that will be the exception, as somewhat warmer air moves in, allowing temperatures to rise to the 12 to 15 C range later. Strong southeast winds 50 to 80 km/hr will become southerly 60 to 100 km/hr later today and eventually southwest 50 to 80 km/hr by this evening as the winds generally start to moderate.

    TONIGHT ... Rain dying out over parts of the south and west, scattered showers then just drizzle before morning, fog patches and quite mild compared to recent nights, lows 8 to 11 C. Strong winds may continue for part of the night slowly veering to southwest then easing by Tuesday morning.

    TUESDAY ... Partly cloudy, showers, somewhat warmer with highs 14 to 16 C. Longer sunny intervals by afternoon. Winds moderate southwest backing to southerly 40 to 70 km/hr.

    WEDNESDAY to FRIDAY ... Partly cloudy to sunny, rather chilly nights with frosts in some places, but gradually warming in the daytime hours to highs of 16 to 18 C and locally 18 to 20 in midlands and western counties by Good Friday. Light winds with some local sea breezes likely to develop as it warms up inland. Those may keep temperatures closer to 12 C along some coastlines.

    EASTER WEEKEND ... Partly cloudy to sunny with a slight risk of rain in the north by later Sunday into Monday. Warm especially inland with light southwest winds becoming moderate by Sunday in west and north. Highs each day 18 to 21 C except for some 12 to 16 C readings near some coastlines.

    FURTHER OUTLOOK ... The guidance is beginning to return to that earlier theme of quite cold weather after Easter, so perhaps this time it's a bit more likely to materialize. Temperatures may fall considerably by about Tuesday 23rd.


    My local weather on Sunday was overcast with glimpses of sun, early morning rain that ended after sunrise, and local blustery showers late afternoon, with highs about 12 C. We are moving very slowly into our growing season locally although they are well advanced on the coast.

    Forecasts for Ireland



    TRENDS for the week ahead (16 to 22 April)

    -- Temperatures will be 1 to 3 deg above normal, the larger departures in the midlands, west and inland north.

    -- Rainfall will be light, 2 to 5 mm except for some risk of 5 to 15 mm amounts in the north by very end of the interval (Monday 22nd).

    -- Sunshine will be above normal values for most, 5 to 8 hours a day likely. Some persistent low cloud may reduce those amounts near some coasts especially in the north.

    -- Winds will become rather light for much of this interval.


    FORECASTS


    TODAY ... Last of the rain ending soon in east Ulster and north Leinster, with a gradual clearing trend from Munster spreading north and east, followed by patchy cloud again this afternoon and isolated drizzle or light rain in one or two locations. Moderate southerly winds 40 to 60 km/hr and highs 12 to 15 C.

    TONIGHT ... Partly to mostly cloudy, mild, lows 5 to 8 C.

    WEDNESDAY ... Hazy sunshine at times, some persistent low cloud in parts of south and also northwest. A little warmer, highs 13 to 16 C.

    THURSDAY and FRIDAY ... Hazy sunshine, low cloud or sea fog possible near south coast, warmer except for some coastal areas subject to onshore sea breezes. Highs 16 to 19 C (but 11 to 15 C in sea breezes). Low temperatures quite variable due to cloud cover mingled with clear spots, where some slight frosts could develop.

    SATURDAY ... Increasing cloud, warm, highs 17 to 20 C except cooler near south and west coasts.

    EASTER SUNDAY ... Some sunny intervals, a little cooler with highs 13 to 16 C. Early morning temperatures should be quite mild at 7 to 9 C.

    MONDAY ... Cloudy, cooler, some rain at times becoming moderate at times in the north. Highs 11 to 14 C.

    OUTLOOK ... The cooler and unsettled weather will then continue for a day or two longer with a slight warming trend towards the end of the week.

    My local weather on Monday was mostly cloudy with a few nearby showers once again largely missing my location. The high was 13 C.

    Forecasts for Ireland



    TRENDS for the week ahead (17 to 23 April)

    -- Temperatures will be 1 to 3 deg above normal, the larger departures in the midlands, west and inland north.

    -- Rainfall will be light, 2 to 5 mm except for some risk of 5 to 15 mm amounts in the north by later in the interval (mostly on Monday 22nd).

    -- Sunshine will be above normal values for most, 5 to 8 hours a day likely. Some persistent low cloud may reduce those amounts near some coasts especially in the north. The sunshine amounts will fall later in the interval.

    -- Winds will become rather light for much of this interval.


    FORECASTS


    TODAY ... Hazy sunshine at times, some persistent low cloud in parts of south and also northwest. A little warmer, highs 12 to 16 C.

    TONIGHT ... Some cloudy intervals with clear spells, lows rather variable depending on duration of clear skies, 2 to 7 C.

    THURSDAY and FRIDAY ... Hazy sunshine, low cloud or sea fog possible near south coast, warmer except for some coastal areas subject to onshore sea breezes. Highs 16 to 19 C (but 11 to 15 C in sea breezes). Low temperatures quite variable due to cloud cover mingled with clear spots, where some slight frosts could develop. On Friday, it's possible that a few parts of the inland west and midlands could reach 20 or even 21 degrees.

    SATURDAY ... Increasing cloud, warm, highs 17 to 20 C except cooler near south and west coasts. Some rain by late in the day in north.

    EASTER SUNDAY ... Partly cloudy to overcast at times, with a few outbreaks of showery rain in counties around Cavan and Monaghan spreading to north Leinster, but staying dry in many places with some sunny intervals, a little cooler than the earlier parts of the Easter weekend with highs 13 to 18 C. Early morning temperatures should be quite mild at 7 to 9 C.

    MONDAY ... Partly cloudy to overcast, cooler, some rain at times becoming moderate at times in the north. Highs 11 to 14 C.

    OUTLOOK ... The cooler and unsettled weather will then continue for a day or two longer with a slight warming trend towards the end of the week. The pattern next week is somewhat uncertain with guidance beginning to take on quite a spread of outcomes, some have the warmer spell returning and others stay cooler all week. This should be resolved in the next few days.

    My local weather on Tuesday was sunny with increasing cloud by afternoon and highs near 13 C.

    Thursday, 18 April, 2019

    Forecasts for Ireland



    TRENDS for the week ahead (18 to 24 April)

    -- Temperatures will average 3 to 5 degrees above normal, highs 18 to 22 C.

    -- Rainfall will be either zero or very light to Monday then uncertainty about trends, most likely a near normal outcome overall but possibly less if the Monday to Wednesday rainfall holds off to the west.

    -- Sunshine will be above normal overall with 7 to 12 hours a day in the first four days of the interval and possibly rather low sunshine totals thereafter, although that will follow the same uncertainty as the rainfall and if it proves drier then also likely sunnier.

    -- Winds will continue very light for most of this interval.

    ============

    FORECASTS

    TODAY ... Hazy sunshine for most, some low cloud and onshore sea fog or mist near south coast. Warmer with highs 18 to 21 C except for cooler sea breeze regimes near east and south coasts (highs 11 to 16 C in those coastal areas).

    TONIGHT ... Some cloud and mist developing, but otherwise clear, lows 5 to 10 C but with the possibility of a few colder pockets inland. With clear skies the next few nights you will see the full moon (the precise timing for that is 12:19 IST on Friday). Jupiter is now rising about midnight so if you happen to see a bright golden-hued star low in the southeast, that's Jupiter, Venus rises much closer to sunrise and you could see it in the hour before dawn twilight in the southeastern sky.

    FRIDAY ... Sunny and very warm with local sea breezes cooling south and east coasts. Highs for most 19 to 23 C. Near south and east coasts about 14 to 17 C.

    SATURDAY ... Sunny with some afternoon cloud, more prevalent in the north. Very warm again, with sea breezes appearing on all coasts but otherwise highs 19 to 24 C.

    EASTER SUNDAY ... There may be some intervals of cloud and isolated showers but no real breakdown of the warm spell in general so that with at least some sunshine highs will likely reach 18 to 20 C and possibly higher in parts of the inland south and midlands. Early morning temperatures are likely to be in the 7 to 10 C range.

    MONDAY ... Guidance becomes rather divided by Monday, some indications suggest cloud and increasing risk of rain near south and west coasts, other suggestions prolong the warm and dry spell at least one additional day. We'll have to wait and see which option dominates the charts by tomorrow, but with the rain and cloud option highs would fall back to about 15 C, in the less likely dry scenario, staying closer to 19 or 20 C.

    FURTHER OUTLOOK ... That uncertainty continues to split the guidance for most of next week. One camp suggests that cloud and rain will be fairly frequent and temperatures will cool off to 12 to 14 C. Other indications keep some influence of the warmer, drier air mass especially over east and north. There are hints of a significant cooling trend in early May. (seems like each month recently has started cold and ended warm)

    My local weather on Wednesday was partly cloudy to overcast with some rain in the morning, highs near 12 C.

    Friday, 19 April, 2019

    Forecasts for Ireland




    TRENDS for the week ahead (19 to 25 April)

    -- Temperatures will average 2 to 5 degrees above normal, highs 18 to 22 C will be common until Monday, then somewhat cooler. Also locations near east and south coasts may average closer to the 2 deg cited and highs more typically 14 to 18 C.

    -- Rainfall will be either zero or very light to Monday then next week is likely to produce near normal rainfall for the interval at least in the south and west, amounts may only reach half the normal seven-day totals in the east and north.

    -- Sunshine will be above normal overall with 6 to 12 hours a day in the first three days of the interval and possibly rather low sunshine totals thereafter, so that overall this coming seven day interval will be near normal for total sunshine. South and east coasts may not fare as well in the first part of the interval due to low cloud from the Irish Sea and Atlantic.

    -- Winds will continue very light for most of this interval.

    ============

    FORECASTS

    TODAY ... Sunny and very warm except where local sea breezes cool parts of the south and east coasts. Highs for most 19 to 23 C. Near south and east coasts about 14 to 17 C. Some persistent low cloud, sea fog or mist could come and go near these coasts.

    TONIGHT ... Clear intervals but extensive mist likely, lows 7 to 10 C.

    SATURDAY ... Sunny with some afternoon cloud, more prevalent in the north. Very warm again, with sea breezes appearing on all coasts but otherwise highs 19 to 24 C. Some low cloud and isolated showers could brush parts of Donegal from a frontal system moving past to the north.

    EASTER SUNDAY ... There may be some intervals of cloud and isolated showers but no real breakdown of the warm spell in general so that with at least some sunshine highs will likely reach 18 to 20 C and possibly higher in parts of the inland south and midlands. Early morning temperatures are likely to be in the 7 to 10 C range.

    MONDAY ... Rain likely in the west and parts of the south, highs near 15 C, but partly cloudy to overcast further east and continued rather warm there with highs about 18 C.

    OUTLOOK ... Frequent light rain seems likely but is more probable in the west as Britain may remain dry for most of the week, so the transitional zone could be Leinster and parts of Ulster with smaller amounts of rain possible. Highs will slowly cool to 12-14 C and it may be even cooler by end of the week, briefly though as warmer air is indicated by Sunday 28th.

    My local weather was overcast with occasional light rain by afternoon, and the high was 14 C.

    Saturday, 20 April, 2019

    Forecasts for Ireland



    TRENDS for the week ahead 20 to 26 April, 2019

    -- Temperatures will be 2 to 4 deg above normal, often around 20 C at first, then 15 to 18 C.

    -- Rainfall will increase during the seven day interval to become near normal in some southern and western counties, but still a little below average in north and east.

    -- Sunshine will average 5 to 8 hours a day, close to normal for late April.

    -- Winds will freshen slowly during the period but will remain light for several more days.


    ===============


    FORECASTS

    TODAY ... Intervals of cloud and sunshine, hazy and warm for most, highs 18 to 22 C. Somewhat cooler near south coast with some low cloud and sea fog likely to encroach. This may also be the case on outer headlands of west and north coasts. Highs 13 to 16 C there.

    TONIGHT ... Mostly cloudy, quite mild, foggy or misty. Some light rain or drizzle at times in Atlantic coastal districts. Lows 7 to 11 C.

    EASTER SUNDAY ... Some brighter intervals likely in east, midlands, and north, rather cloudy to overcast in south and west, where light rain or drizzle may develop at times. Highs 17 to 21 C.

    MONDAY ... Outbreaks of showery rain in west Munster, low cloud and sea fog near other parts of south and west coasts, variable cloud elsewhere with some brighter intervals, remaining quite warm. Lows 7 to 11 C and highs 16 to 20 C.

    TUESDAY ... Little change from Monday overall, rain may spread a bit further east at times, and temperatures could be one or two degrees lower in most places but still above normal values.

    OUTLOOK ... Frequent light rain, fresher temperatures in 13 to 16 C range.

    My local weather on Good Friday was bad, low cloud, persistent rain, cool highs near 10 C. This is the first really wet soaking day we have had in a long time and it was probably necessary for growth but still, looking forward to sunshine and warm temperatures but will have to drive south for two days to get them, as we expect only minor improvements here on Saturday.

    Sunday, 21 April, 2019

    Forecasts for Ireland



    TRENDS for the week ahead 21 to 27 April

    -- Temperatures will be 2 to 4 degrees above normal, but trending slowly back towards normal values by end of the week.

    -- Rainfall will be near normal for the week ahead, although somewhat unevenly distributed.

    -- Sunshine will average 3 to 6 hours a day, slightly below normal, with a cloudier trend later in the week.

    -- Winds will often be moderate south to southwest as the week progresses.


    FORECASTS


    TODAY ... Some hazy sunshine and warm in eastern and central counties, warm with highs 18 to 22 C except 14 to 17 C along east coast. South coast and some distance inland will be overcast with some fog and mist at times, highs 14 to 16 C. Western and some northern counties will also be mostly cloudy with a few breaks, and outbreaks of light rain possible although not in all locations. Highs 15 to 19 C.


    TONIGHT ... Mostly cloudy with some clear breaks in north and east, mild, outbreaks of rain in west Munster. Lows 8 to 12 C.

    MONDAY ... Partly cloudy to overcast, warm. The rain near west coast may back away into the Atlantic for a period then return to the south coast later. Highs generally near 20 C except cooler near most coasts where sea fog may drift inland.

    TUESDAY ... Partly cloudy east and north, with isolated showers or thunderstorms developing. Variable cloud south and west with outbreaks of rain, some mist or fog. Lows near 12 C and highs near 18 C.

    WEDNESDAY ... Rain at times (10-15 mm) and highs near 16 C.

    THURSDAY ... Showers, breezy, rather cool with highs near 14 C.

    OUTLOOK ... Frequent showers in an unsettled westerly flow, temperatures near normal.

    My local weather started out misty but turned sunny in the afternoon, and the high was 16 C.

    Happy Easter ... I will be posting a forecast on Monday then taking a week away, hoping to arrange for the posting of daily forecasts during that interval.

    Monday, 22 April, 2019

    Forecasts for Ireland



    TRENDS for the week ahead 22 to 28 April 2019 ...

    -- Temperatures will average 1 or 2 deg above normal but the trend through the interval will be from above to below normal.

    -- Rainfall will be at least average for the seven days and in some central regions may be as much as 50% above normal.

    -- Sunshine will average 2 to 5 hours a day, below the normal for late April.

    -- It will gradually become quite windy at times later in the week.


    FORECASTS

    TODAY ... Some hazy sunshine and warm, but cloud will begin to dominate and a few showers could develop mostly in south and midlands. Highs 18 to 21 C.

    TONIGHT ... Mostly cloudy, humid, mild with a few light showers. Lows 11 to 13 C.

    TUESDAY ... Variable cloud, outbreaks of showery rain and isolated thunderstorms possible, but rainfall only 1 to 3 mm for most places. Highs around 18 C.

    WEDNESDAY and THURSDAY will become rather wet (10-15 mm rainfalls possible each day) with the track of the heaviest and most persistent rain through the southeast into the midlands and then north Connacht. Highs around 15 C Wednesday and 13 C Thursday.

    FRIDAY will see stronger winds developing and some outbreaks of heavy rain, and it will not be very mild during this with highs of 9 to 12 C. Windy and colder late in the day, sleet or wet snow showers are possible in the north on higher terrain.

    FURTHER OUTLOOK ... Although likely to stay rather cool, the weather will be somewhat more settled towards the end of the month, with rain less frequent. Highs will only be in the 9 to 12 C range even into early May.

    My local weather on Easter Sunday was sunny with a high near 16 C. As I mentioned, heading out for a week of back country camping down south, back around the first of May but sryanbruen and perhaps one or two others will pitch in and keep you up to date. Thanks to them for their efforts.

    Tuesday, 23 April, 2019

    Forecasts for Ireland

    TRENDS for the week ahead 23 to 29 April 2019 ...

    -- Temperatures will average 0.5 to 1.5 degrees Celsius above normal for the period but differences from average will decrease as time passes with cooler conditions becoming dominant by the latter part of the week.

    -- Rainfall will be on the rise with low pressure nearing our shores and increasingly dominant. Expected to be within 80 to 150% of average though locally intense showers or rain could mean even wetter for some isolated spots. Towards the end of the period, there is a signal for the winds to turn into the north which whilst cool would mean rather drier conditions for Ireland as the low pressure sets up to the east or southeast of the UK.

    -- Sunshine will average 2 to 5 hours per day, dullest in the west, making it a rather dull end to April.

    -- There is likely to be some very windy episodes to end the month especially later in the working week. Windiest conditions likely since mid-March.

    FORECASTS

    TODAY ... A mostly cloudy start to Tuesday with some showery outbreaks of rain pushing northwestwards in a moderate east to southeasterly wind flow. There could be the odd rumble of thunder associated with these showers. Clearer conditions expected to push in from the east of the country through the late morning and into the afternoon as the showers continue to push to the northwest. Staying rather cloudy in the west but even here there should be some sunny spells now and then. One final rather warm and humid day with maximum temperatures ranging from 13 to 21c, warmest in the west and coolest on eastern coasts.

    TONIGHT ... Mostly dry to start with some mist forming as the southeasterly winds continue but showers will start to push in from the southeast later in the night affecting Leinster and Munster initially. A rather mild night with minimum temperatures getting down to 8-11c. There might be some saharan dust in the air so should make for quite the sunset if you can catch it this evening.

    WEDNESDAY ... Showers will have made their way westwards into Connacht whilst continuing in Munster and south Leinster. Elsewhere, there is likely to be spells of sunshine to start Wednesday but it will be a showery Wednesday afternoon almost everywhere. Thunder is very possible in these showers. Maximum temperatures still on the relatively mild side reaching 17 or 18c in the north but in the showers dropping to more near normal values of 13-15c, winds moderate in easterly direction. Showers will continue on Wednesday night.

    THURSDAY ... Very showery with scattered outbreaks of rain and thundery showers over the country. Southeasterly winds becoming gusty making for a blustery day and quite a change from recent days. Variable spells of sunshine and cloud in between the showers so it's not all doom and gloom. A cooler day everywhere with maximum temperatures ranging between 11-15c, over 10 degrees Celsius cooler for some places from the values achieved during the Easter weekend. It should become drier for a time Thursday night into early Friday morning with temperatures dropping to the low single figures in rural areas in clear skies.

    FRIDAY ... A dry start on Friday with some early morning grass frost possible in sunny spells but this will be quickly replaced by a band of rain pushing in from the Atlantic with the wind veering westerly direction simultaneously. Maximum temperatures during the afternoon ranging between 10-14c. Becoming windy with this low but strongest gusts likely further north near Scotland and into Saturday. The rain should clear by Friday evening leaving scattered showers behind but temperatures will take a tumble during the night with grass frost again likely in the odd spot.

    SATURDAY ... A blustery day with showers feeding in on a gusty west to northwesterly airflow. Maximum temperatures ranging between only 9-12c which is not too far off the average late April highs but compared to the Easter period, it will feel quite chilly particularly in the wind.

    OUTLOOK ... The outlook is a familiar changeable one for Ireland with westerly winds for the end of April. There is some signals from the models to take high pressure up to Greenland during early May which would mean the wind direction turning northerly. This would result in cool and mainly dry conditions for Ireland bar the possibility of showers. This is nothing too unusual however as early May is often a time when Greenland blocking forms as was the case in Mays 2010 and 2017 for recent examples.

    Wednesday, 24 April, 2019

    Forecasts for Ireland

    TRENDS for the week ahead 24 to 30 April 2019 ...

    -- Temperatures will average 0.2 to 1.0 degrees Celsius above normal for the period but becoming cooler and cooler as time passes to the point where below average temperatures are likely by the weekend.

    -- Rainfall will be above average for most places with low pressure circulating around our shores for the next few days. Expected to be within 80 to 150% of average though locally intense showers or rain could mean even wetter for some isolated spots. There is now the signal for high pressure to become influential by this time next week rather than northerly winds but whether it'd be a blocking anticyclone or northern blocking over Greenland/Scandinavia which would result in easterly winds is open to question.

    -- Sunshine will average 2 to 4 hours per day, dullest in the west, making it a rather dull end to April.

    -- Quite a windy period expected for late April during the next few days but it should start to become calmer by next week.

    FORECASTS

    TODAY ... Various sunny spells but mainly cloudy with outbreaks of showery rain tracking its way northwards with the risk of thunder. Warmest in the north today with maximum temperatures up to 17 or 18c but elsewhere, it will be cooler than recently with highs ranging between 13-15c though these are only closer to average. Some brightness will attempt to ascend from the south later in the day whilst some more showers cannot be ruled out. Winds moderate east to southeast in direction.

    TONIGHT ... Further risk of heavy or thundery showers tonight for a time as they clear their way northward with some clear skies in the south. Fresher than recent nights but still not faring too badly with minimum temperatures in the 4-7c range, coolest in the south.

    THURSDAY ... Blustery with widespread showers scattered about over the country. Some of these could form into longer spells of rain with heavy and prolonged periods, possibility of thunder again. Southeasterly winds becoming gusty with maximum temperatures by this time ranging between 11-15c. Now, there's the likelihood that a band of rain will push across the country later on Thursday night into Friday morning after some temporary clearer skies develop once the showers fizzle out. Cloud from the rain will prevent the grass frost from forming with minimum temperatures holding up to mid single figures.

    FRIDAY ... Some rain to start Friday clearing the east will be followed by another band of rain pushing in from the Atlantic and make its way across the country through the day. This one will be associated with stronger winds, unlikely to be a named storm however right now though it is a possibility. Brighter conditions will come in behind the rain later on Friday but also the possibility of some showers. Maximum temperatures ranging between 9-14c.

    SATURDAY ... Sunshine and scattered showers with fairly gusty northwesterly winds, becoming moderate as the day goes on. Maximum temperatures ranging between 9-12c by this point, below average for April though not exceptionally so.

    SUNDAY ... Ridge of high pressure from the Azores attempting to assert itself to the south and east of the country but currently it looks as though it will fail in its process with more wet and windy weather pushing its way into the west of Ireland. Relatively milder as winds veer southwesterly with maximum temperatures ranging between 11-13c, any sunshine could help temperatures rise a bit more.

    OUTLOOK ... Latest models are quite different to what they were showing yesterday and the past few days with the exception of the ECM operational run.

    One scenario is Sunday's low stalling in the west and then sinking southwards with a Scandinavian High setting up turning the winds into the east by the start of May. This would result in dry conditions and mainly average temperatures though as the sun is strong at this time of year, some spells of sunshine can make all the difference. Low cloud possible. This is shown by the current GFS but is unlikely.

    Another scenario is the aforementioned northerly winds with Greenland blocking developing which would be mainly dry but also cool. This is the scenario shown recently and by this morning's ECM but models seem to have gone away with it generally.

    The third scenario is Azores High ridging taking over the pattern with the jet stream being forced northwards. This is the least likely scenario at the moment.

    The exact scenario is important for the kind of temperatures that one would expect but they all have one thing in common, there is a lack of unsettled weather with each of them. It's a case of wait and see.

    Thursday, 25 April, 2019

    Forecasts for Ireland

    TRENDS for the week ahead 25 April to 1 May 2019 ...

    -- Temperatures will average 0.2 degrees Celsius below normal to 0.5 degrees Celsius above normal for the period. These anomalies to average will continue to drop the next few days towards cooler than average.

    -- Rainfall will be above average for most places during the period and this will largely be down to the next few days as the current signal is for drier conditions to return by early May.

    -- Sunshine will average 2 to 3 hours per day which is rather below average for the end of April.

    -- Friday's low pressure system has now been named Storm Hannah by Met Éireann with quite a windy episode for the time of year expected. Models showing this now running along the south and southwest of the country with gusty westerly winds including severe gales in places driven by a strong jet stream.

    Warnings for Storm Hannah from Met Éireann.

    Status Orange - Wind warning for Clare, Cork, Kerry and Limerick

    Becoming stormy on Friday evening and overnight as Storm Hannah moves in. Southerly winds, later veering northwesterly will reach mean speeds of 65-80 km/h with gusts of 110 to 130 km/h.

    Be prepared for possible disruption and power outages


    Status Yellow - Wind warning for Connacht, Carlow, Kildare, Kilkenny, Laois, Longford, Wexford, Wicklow, Offaly, Donegal, Tipperary and Waterford

    Becoming very windy on Friday night and for a time on Saturday morning. Southerly winds will veer northwesterly and reach mean speeds of 50-65km/h with gusts of 90 to 110 km/h.


    FORECASTS

    TODAY ... After a dry start for some this morning, heavy showers will spread in from the southeast in moderate southeast breezes. These could be associated with thunder and hail in places, heaviest in the south and west. Maximum temperatures close to average for late April reaching afternoon values of 11-15c.

    TONIGHT ... Showers will gradually peter out tonight but these will only be replaced by a band of rain pushing in from the west so the cloud and rain will prevent grass frost from developing with a mild night expected. Minimum temperatures likely to range between 4-7c.

    FRIDAY ... Mostly cloudy with rain clearing eastwards during the morning will be followed by Storm Hannah pushing in from the Atlantic and make its way across the country later in the day. Hannah is likely to bring severe gales among southern counties particularly on exposed coasts with gusts in excess of 110 km/h for various places of the southwest Friday evening and Friday night. There has been several changes in the possibility for Hannah's track which made it important to see if we would be impacted heavily but now it's looking that she will push along the south of the country during Friday evening and night into Saturday morning resulting in some very gusty west to northwesterly winds. Maximum temperatures for Friday ranging between 10-13c.

    SATURDAY ... Continuing very windy to start off Saturday morning but rain should clear eastern regions by the latter part of the period with brighter conditions developing behind. It will however be blustery in strong northwesterly winds, easing somewhat later on, with some scattered showers feeding in. Maximum temperatures ranging between 9-12c.

    SUNDAY / MONDAY ... An area of low pressure in the Atlantic is trying to push eastwards but is being forced to stay just out west for Sunday on the latest models with ridging from the Azores trying to build to the southeast of us and link up with blocking over Greenland and Scandinavia. Sunday is likely to be a cloudy day with winds veering southwesterly meaning it is expected to be a milder day. Maximum temperatures on Sunday ranging between 12-15c. Limited amounts of brightness with patches of drizzle though amounts will be small. There is some uncertainty surrounding when this band of rain is going to push in from the west as well as if it's going to make full progress eastward or just fizzle out as high pressure becomes established after making the outlook somewhat complicated.

    OUTLOOK ... The signals now favour an easterly flow for early May but instead of a Scandinavian High, models are showing an Icelandic High with a scenario sort of similar to early May 2017 which was very dry and sunny. Initially, there is the possibility of showers as low pressure attempts to fizzle out but then high pressure ridges in from the north, east to northeast winds being the mean wind direction. This would mean that eastern regions would be relatively cool but in the west under any sunshine, temperatures could get into the very respectable teens of up to 16-18c or even more.

    The outlook for early May will not be resolved however until Sunday / Monday's low is as it puts complications in the forecast.

    FORECASTS

    TODAY ... Rain clearing eastwards will be followed by another band of rain associated with Storm Hannah pushing in from the west through the day with a window of calmer and brighter conditions in between. Becoming windier and windier through the afternoon and evening with maximum temperatures ranging between 8-13c.

    Severe gale gusts are likely in the southwest and south of the country with violent storm force winds on exposed coasts or mountain tops to the west and southwest. This is looking like the windiest period of April weather in a long time and with trees in leaf, damaging impacts will be felt. There is the possibility of the orange wind warning in the southwest turning red later on which would be the first red warning for Ireland since Storm Emma back at the start of March 2018. There is certainly a danger to life with the expected wind gusts in the southwest if you're not extra careful through this evening. Try not to make unnecessary journeys and do not wait around for a red warning to come if you're residing in the south and southwest. Better safe than sorry as they say.

    TONIGHT ... Severe gales will blow their way across the southwest during the evening and for a time tonight before dying down somewhat though remaining very windy through the period. Showery outbreaks of rain continue to push across the country but becoming isolated and clearing eastward later on. A relatively mild night under the windy conditions with minimum temperatures ranging between 4-7c.

    SATURDAY ... Once the last of the rain clears the east or northeast, Saturday will be a blustery day with sunshine and scattered showers. Northwesterly wind gusts still strong in nature though easing as the day goes on. Maximum temperatures on the cool side reaching afternoon highs of between 8-12c.

    SUNDAY / MONDAY ... Now it looks as though that both Sunday and Monday will be mainly dry and cloudy days as the rain attempts to stay out west for a time before pushing in later on Monday. Patches of light rain, drizzle and mist forming with the cloud on both days. Wind direction veering southwest to southeasterly meaning it will be milder than recent days with maximum temperatures ranging between 12-16c on both days.

    TUESDAY ... Currently, Tuesday looks to get off to a wet start as rain clears eastwards but brighter conditions following on from behind with well scattered showers. Maximum temperatures around average for late April ranging between 11-14c.

    OUTLOOK ... Some huge differences with the models this morning as the GFS shows largely settled conditions to start off May as pressure rises after initial showers from slack pressure. It even shows a very pleasant May Day bank holiday weekend with sunny spells and conditions turning warmer. The ECM in contrast develops a proper northerly flow for a time with low pressure over Scandinavia, wouldn't be wet for Ireland but very cool. It then goes on to develop a southwesterly flow near the end of the first week with low pressure spreading in from the west. Questions still to be answered regarding early May it seems.

    SUNDAY ... Some isolated/patchy outbreaks of light rain or drizzle in places, but predominantly dry for most areas. Moderate southwesterly breezes and milder than recent days, with temperatures ranging between 12c and up to 17c where any sunny spells develop (sunny spells most likely to the south and south west).

    Forecasts for Ireland



    First of all, many thanks to the guest forecasters who had their hands full with very active weather while I was away. Your efforts are greatly appreciated by me and I would suspect also by the regular readers of this thread.

    I enjoyed some very pleasant warm and mostly sunny weather in the southwestern U.S., with highs mostly in the 24 to 28 C range in southern Utah. We drove back through steadily falling temperatures but it stayed dry and in fact the only rain I saw all week was from a couple of evening thunderstorms.

    TRENDS for the week ahead ... 1 to 7 May

    Temperatures will average about 2 degrees below normal, with highs mostly in the 10 to 13 C range, and some risk of frosts on some nights.

    Rainfall will average below normal amounts although just after this interval ends, it may become quite wet.

    Sunshine will probably be at least normal and could be a bit above average.

    No strong winds are expected and the flow will be generally northerly in direction.

    FORECASTS ...

    TODAY will see increasing cloud by mid-day and afternoon with showers developing in parts of the west, spreading somewhat further east by late in the day. Amounts of 2 to 5 mm are possible where it does rain. Rather cool with highs only 10 to 13 C.

    TONIGHT will remain cloudy with a few showers, lows 4 to 8 C.

    THURSDAY will bring a mixture of cloud and sunshine, and scattered showers, highs 11 to 14 C.

    FRIDAY will become somewhat cooler with occasional showers, more frequent in north and parts of the midlands. Highs 10 to 13 C.

    WEEKEND OUTLOOK is for dry and rather cool weather, generous amounts of sunshine but risk of frosts, lows -2 to +3 C and highs 9 to 13 C.

    NEXT WEEK will begin to turn very cool and at times rather wet as colder air moves in from the north while the storm track drops to the south of Munster, sometimes providing moderate northeast winds and rain. Highs most days will only be around 10 to 12 C and could be even cooler in some places.

    My local weather on Tuesday was partly to mostly cloudy and cool with highs near 10 C.

    Forecasts for Ireland



    TRENDS for the week ahead ... 2 to 8 May

    Temperatures will average about 2 or 3 degrees below normal, with highs mostly in the 10 to 13 C range, and some risk of frosts on some nights.

    Rainfall will average about normal amounts although most of that will fall after the weekend. The following week looks quite wet also, especially in north Leinster and south/east Ulster.

    Sunshine will probably be around normal amounts with the weekend (including holiday Monday) a bit above average.

    No strong winds are expected until about Tuesday when moderate northeast winds are possible.


    FORECASTS ...

    TODAY will be partly to mostly cloudy with outbreaks of light rain in various places, both north and south, but amounts fairly slight, 2 to 5 mm on average. It will remain rather cool with highs 11 to 14 C.

    TONIGHT will be overcast at first with a slight clearing trend, as showers become more isolated, lows 3 to 6 C.

    FRIDAY will remain quite cool with occasional showers, more frequent in north and parts of the midlands. Highs 10 to 13 C.

    SATURDAY will bring a gradual clearing trend with some scattered morning frosts, lows -1 to +3 C, then highs of about 10 to 13 C under partly cloudy to sunny skies.

    SUNDAY and MONDAY will continue fair but colder than average for early May, with frosts, lows -2 to +3 C, and highs only 9 to 13 C despite generous amounts of sunshine.

    TUESDAY will become cloudy and chilly with rain developing in northeast winds. Lows near 5 C and highs 8 to 12 C.

    The outlook calls for similar weather at times in the following week and only a slight warming trend into the second week of May.

    My local weather is about the same, overcast with light rain and chilly daytime highs of only 9 or 10 C. The progress of spring blooming around here is quite slow and leaves are just slowly opening out then deciding it's not a good idea.
