I was only 5 at the time. I have vague memories of that particular spell and that particular winter.
Thanks for the reminder, I forgot.

My Winter 1978-79 historical post can be read about here (since some enthusiasts were so eager to see it at the time ): https://www.boards.ie/vbulletin/show...&postcount=801
Hi Sryanbruen the link won't work for me. What page is it on? Cheers.

My memories of that spell was staying in my grandparents house in County Galway for few days around Xmas as we sometimes did. Think we came home ( living in Dublin at the time) around 1st or 2nd of jan it would have been. I remember there being not much snow on the ground in Galway. As we drove eastwards on the old Dublin- Galway road heading back home I remember the amount of lying snow increasing the further east we got. It was well into the night before we got home but the difference between the amount of snow in Galway compared to Dublin I have always remembered. That drive home has always stuck in my mind even though I was only 5.
I do remember that being a snowy winter and I remember snow in March that yr and even some snow as late as may. Vague memories but memories all the same.

After seeing the July 2018 data released publicly for Kilkenny (Greenshill), it seems that the station recorded 18 consecutive days of heatwave conditions (maximum of 25.0c or greater) from 24th June to 11th July. This is 4 days longer than the previous known longest heatwave (using the definition from Met Éireann) in Ireland which was 14 days in Birr during August 1976.

Still waiting on August 2018 data though to do my Summer 2018 report.

January 1881 was a severely cold and snowy month in the UK & Ireland with some of the biggest snowfalls ever seen in England and the coldest temperatures over Ireland in history.

The month had a CET of -1.5c making it the joint seventh coldest January on record since 1659 up to 2018. The period 8th to 27th January 1881 had a CET of -4.4c and it was -1.5c overall as a result of the relatively mild start and mild end especially the latter period. Winter 1880-81 had a mean temperature of around 2.8c at Phoenix Park, Dublin and this made it the sixth coldest Winter on record at the station; this was solely down to what happened in January as December 1880 had been relatively mild and February was only chilly rather than bitterly cold.

Given what I've described so far, it would be a surprise to see that January 1881 started off relatively mild with a westerly flow in charge as high pressure sits to the south and low pressure to the north although the high pressure tended to be more influential blocking the lows crossing the country. It wasn't very mild by any means but this was some of the mildest weather the country had seen all month. Galway had a maximum of 10.0c on the 2nd. Other parts of Ireland and the UK had similar values during the period but somewhat lower although Londonderry had a maximum of 11.7c on the same day. It was damp and misty with this high pressure.



High pressure began to intensify over us and retrogress to Greenland by the latter part of the first week of January. This resulted in conditions becoming gradually cooler. This high had fully retrogressed by the 11th with cold air flooding in from the northeast and troughs developing in the flow which meant the air was unstable resulting in snow showers beginning to occur. It was a very similar scenario to that of late November 2010. From this point up to the 16th to 19th, it just got colder and colder with the cold weather getting more severe.





The northeasterly winds became very calm on the 16th resulting in frosts of unusual intensity with deep snow cover lying on the ground from near constant snow showers and continuous cold weather. Markree Castle, Co. Sligo got down to -19.1c on the morning of 16th January 1881 which is the lowest minimum temperature on record for any month in the Republic of Ireland to this day. Killaloe, Co. Clare recorded -13.9c. Phoenix Park had a maximum temperature of -3.1c on the 15th and -2.8c on the 16th (two of the 7 ice days that the station recorded during January 1881). Kelso, Scotland got down to -22.2c on this day whilst there was an observation of -24.4c on the same day at Blackadder, Scotland but the latter figure is disregarded from official records.



Low pressure from the Atlantic pushed to the south of the UK and Ireland driven by the southerly tracking jet stream on the 17th/18th and developed into a Channel Low. This went on to become one of the worst blizzards that England had seen in history and perhaps even THE worst. The snowfalls started on the 17th in the southwest of England and at the same time, an easterly gale became evident with snow drifting in the wind as a consequence. This continued in some places for a good 48 hours.

Meanwhile, the severe frosts continued further north over Ireland and Scotland including an observation of -30c at Blackadder (which again was disregarded due to possible non-standard exposure). Kelso recorded -26.7c on the 17th January 1881 which was the lowest temperature on record in the UK until February 1895 (which would later be equalled twice in January 1982 and December 1995).

I'll let H. Sowerby Wallis, whom contributed to Symons' Meteorological Magazine, explain the situation with his in-depth article on the snowstorm of January 1881 in the February 1881 issue of the named magazine.

Quote:
After the 9th of January, snow fell daily on some portion of the British Isles and on the 12th and 13th rather heavily over the greater part of them, so that by the 17th (on which day practically none fell), there was a considerable depth on the ground over the whole of the United Kingdom, the weather having been so cold that scarcely any had melted. This depth averaged three to four inches over the greater part of England, and rather more in Wales, the N. of England and in Scotland. During the early morning of the 18th the wind, which was easterly, rapidly increased in force, and blew a strong easterly gale nearly all day, the wind falling again in the south at night, but in other parts of the country it lasted till about mid-day on the 19th. The gale was particularly severe on the east coast, but the number of wrecks and casualties all round our shores was very great; reports from many seaports stating that it was the most severe gale that had been experienced for more than 30 years. Much damage was done to roofs and a very large number of trees were blown down in the eastern counties - e.g. Lord Rendlesham reports over 1,500, most of them large ones, blown down in his estate and there were many isolated cases of structural damage in other parts of the country. In London an extremely high tide, increased by the gale, overflowed the low-lying districts on the south of the Thames, causing great distress, augmented by the extreme severity of the weather, among the poorer classes.

The gale was accompanied by a heavy and steady fall of snow over all but the north of England, which lasted through the 18th and continued, though rather lighter, till about noon on the 19th. The amount of snow deposited over the whole of the southern portion of the country was very great, and was so drifted by the fierce wind, that communication both by rail and road was entirely disorganised, and it was more than a week before the railway and postal arrangements throughout the country recovered their usual regularity and punctuality ; the interruption to business was further increased by the large number of telegraph wires which were broken by the gale or by contraction caused by the extreme cold.

Snow fell again on the 20th in the S. and S.W., very heavily in the Isle of Wight and neighbouring districts, blocking up many lines of railway that had with great difficulty been cleared from the fall of the 18th.

Among careful observers in all parts of the country where the snow fell with its full intensity, it appears to be the general opinion that to find anything like a parallel case we must go back to 1836 or to 1814 ; and it would appear that in most parts of the country, the depth in those years was greater but that the drifts were not so great. As regards the fall in the Isle of Wight and South Hampshire, it is believed to be altogether unprecedented in recent times.

One feature of the snow which appears to have been noticed nearly all over the country was its extreme fineness and dryness, and the remarkable manner in which it penetrated in large quantities through roofs, the cracks of doors and windows, and even the most minute and almost imperceptible crevices.

The loss of life in England and Wales, entirely due to the snow, was very great and probably an estimate of 100 persons would be very near the truth, and the amount of distress occasioned simply by the stoppage of the supplies of food and fuel to country districts from towns is almost incalculable.

Small birds died of starvation in vast numbers, their food being covered by the snow. At Littlehampton, in one shrubbery, more than 100 dead blackbirds and thrushes were found, and the following curious incident is reported in an Isle of Wight newspaper; "A friend of ours looking from his window (in Shanklin) on Monday, saw some larks hopping about on his lawn. Presently some rooks swooped down upon the birds, tore several to pieces, and ate them".

It is very difficult to realise the magnitude of the snowstorm and of the drifts; perhaps some of the men employed in clearing the railways had the best opportunity of doing so. Locomotive engines and trains, in spite of their size and power, were snowed up by the dozen; not merely stopped, but buried for days together, and in some cases so completely as to be quite hidden. From the Tring cutting on the L. & N. W. railway, 1,700 truck loads of snow were taken. A railway truck is about 15 ft. long, therefore 1,700 trucks would form a train nearly five miles long. A train five miles long to empty one cutting on one railway, what length of train would it require to remove the snow from all the cuttings on all the railways in England?

The loss to the country was enormous; over more than half England business was practically stopped for one day at least, and the cost of clearing not only the railways but almost all the roads in the country, is incalculable, not to mention the more or less serious suffering and discomfort. Plymouth was deprived of water for nearly a week. Public and private meetings of all kinds had to be postponed ; in short, that intercourse between man and man, on which the whole business and pleasure of life depend, was interrupted.

There was also snow on the ground over almost the whole of Scotland and Ireland, which drifted considerably, and in some cases caused delay to traffic; but it has no interest in connection with the abnormally heavy fall of the 18th and 19th over the southern portion of England, and therefore needs no further notice.


The severe frosts continued after the blizzard cleared to the east but the Atlantic broke through by the 27th with much milder conditions for the end of the month becoming established resulting in a huge thaw and flooding. Several stations recorded their monthly maximum temperatures during this period including Killaloe (on the 28th), Manchester and Barnstaple (both on the 31st), England with 11.1c.



Minimum temperatures in the UK for selected dates (the Blackadder figures are now disregarded as already stated and many others here are too for the same reason; non-standard exposures) - thanks to Kevin Bradshaw for analysing these.

13th: -18.9C at Cardigan
14th: -20C at Corwen, -19.4C at Corwen, -18C at Achonachie, Alston, Ketton and Lauder
16th: -24.4C at Blackadder. -23.3C at Stobo, -22.2C at Kelso and Corwen, -18.3C at Blackpool, -17.8C at Chester
17th: -30C at Blackadder, -26.7C at Kelso, -26.1C at Stobo, -23.3C at Melrose
18th: -26.1C at Stobo
20th: -19.4C at Cheltenham
21st: -23.3C at Haydon Bridge
24th: -23.3C at Blackadder
25th: -21.7C at Bury St Edmunds
26th: -26.7C at Blackadder

Meanwhile, here's the monthly minimum temperatures for several Irish stations taken from Symons' Meteorological Magazine.

StationCountyMinimum temp.Date
Cork (Blackrock)Cork-13.315th
WaterfordWaterford-12.217th
KillaloeClare-13.916th
PortarlingtonLaois-11.721st
MonkstownDublin-11.717th
GalwayGalway-10.617th

Edenfel, Co. Tyrone got down to a minimum of -19.4c on the 23rd.

Unfortunately, the only information that Met Éireann give in regards to the January 1881 snow in Ireland in their "Snowfall in Ireland" document is:

Quote:
The records at the Phoenix Park, Dublin recorded remarkable snowstorms in January
(O’Reilly, 1981).
It's no wonder why January 1881 was that cold going by its 500mb height anomaly reanalysis. Greenland blocking was very evident and the patterns were similar in ways to late 2010 but the below average heights were deeper in January 1881 and closer to us so there tended to be more moisture.

Some stats on December 2018's sunshine for the UK whilst I was doing my December 2018 review for the UK.

Sunshine was very divided during December 2018 with eastern parts of the country tending to be on the sunnier side but the west was dull and in some parts, exceptionally so with less than half the normal amount of sunshine in an average December.

With a total of 22.6 hrs, it was the third dullest December on record in Northern Ireland back to 1929 behind only 1931 (18.1 hrs) and 1977 (18.7 hrs). In contrast, eastern Scotland recorded a total of 45.7 hrs of sunshine during December 2018 making it the joint sixth sunniest on record in the region. In the southwest England/south Wales series, it was actually the dullest December on record back to 1929 with a total of only 22.7 hrs of sunshine which also made it the dullest month on record in these regions. January 1996 was the previous dullest month on record here with 25.6 hrs of sunshine.

This once again shows just how dry dublin is compared to other parts of the country. Casement less than 650mm of rain and Phoenix Park around 680mm. Would’ve to know how dublin rainfall compares to other European capitals, particularly western and Northern Europe.

It’s amazing how it seems every single year without fail, dublin ends up the driest county in Ireland. I wonder what the reasons are for that?? Cork airport for example got nearly double the rainfall that dublin airport got. Amazing contrast in a country of our size.

So despite all the very dry weather during the Summer and severe drought, 2018 ended unremarkable in terms of rainfall due to January, April, November and December mainly. Saying that, some stations did have quite a dry year and it was the driest year since 2010, 2013 or 2016.

It's down to the combination of its location in the extreme east of the country and in the rain shadow of the Wicklow mountains. So many days you see a clear radar over Dublin with winds with a southerly component.

Thanks for that, makes sense. I always found it strange when two friends of mine from cork and Galway moved to dublin and they would frequently say how little it rains in dublin. While we hardly live in the costa del sol I think in dublin and that east we do take for granted how dry it is in comparison to other parts of the country. If you look at dublin average annual rainfall, that compares quite interestingly vs averages in other European cities in northern and Western Europe. Dublin is actually among the driest! 650mm in 2018 is very low compared to most of northern and Western Europe

Dublin 732mm
Copenhagen 1,100mm
London 601mm
Glasgow 1,079mm
Berlin 591mm
Cardiff 980mm
Manchester 810mm
Amsterdam 766mm
Brussels 818mm

Annual weather summary for 2018 is out.

Annual 2018 – Temperature and Sunshine above average in most places. Storm Emma brought widespread snow.

The year began unsettled with a mainly westerly airflow for January with Storm Eleanor bringing strong winds on the 2nd. A cold and dry February finished with a polar continental air mass. This brought snow showers with significant accumulations in the East and South. Storm Emma at the beginning of March gave widespread snow in a cold and changeable month. The unsettled theme continued during April with temperatures near normal. May started changeable but overall it was a warm dry and sunny month with high pressure dominating. The settled conditions continued for most of June and July apart from Storm Hector in the middle of June, which brought wet and windy weather briefly. Heatwave and drought conditions in many places towards the end of June continued into early July in several places lasting longest in the South and East. Changeable weather returned towards the end of July and continued in the North and West for much of August. The South and East stayed predominantly warm and dry. September and October were cool and dry, however in September Storm Ali brought the strongest winds of the year on the 19th followed by Storm Bronagh, and Storm Callum on the 12th October. It was mild and unsettled for most of November with Storm Diana on the 28th. Atlantic westerlies dominated in December with Storm Deirdre on the 15th.

https://cli.fusio.net/cli/bulletin/d...sum_172018.pdf

This was an unexpected record that I read about in the summary; it was Casement Aerodrome's sunniest year on record (monthly sunshine records back to 1964) with a sunshine total of 1576.8 hrs. I calculated the annual totals for myself to see what its previous record (and top 5) was. You can see the annual sunshine totals for every year from 1964 to 2018 below in the graph.

Looks like it just barely bet the previous record of 2003.

1. 2018 - 1576.8 hrs
2. 2003 - 1572.3 hrs
3. 2006 - 1549.4 hrs
4. 2010 - 1545.0 hrs
5. 1989 - 1530.1 hrs

It also became only the seventh year to have an annual sunshine total of at least 1500 hours of sunshine since the records began at the station, with 1969, 1989, 1995, 2003, 2006 and 2010.

-10.5c is the minimum temperature in the UK for January 2019 (so far) which compared to Januaries since 2008 is among the highest but not THE highest as it equals that of 2012 but lower than 2014 and 2017. 2010 was the only one with a minimum below -15c and -20c.

Been beavering away on trying to get a historical post done today, not sure if I'll post it today or tomorrow. It'll be on the January 1974 storms, as requested and planned.
