    The dullest April record as 2017 kind of surprised me.

    Just going through your 2010 post now Sryan. Excellent stuff indeed.

    Froze were the days!

    Hope it's detailed enough for you to get beside the fire like reading a book :). Only missing one thing for doing so, snowing outside.

    I keep thinking it's too short and I could still majorly improve on it being more detailed. :P

    It's fine as it is.
    It's good to reminisce, especially when there is no snow around. It has also helped alleviate my withdrawl symptoms:)

    Is there anywhere where I could find stats of the top 5 warmest and coldest Easters in Ireland on record?

    Even your own recollections, experiences etc of either month (if you have any obviously) would help hugely.

    I don't have any stats for the Jan 1982 snowfall event but this may be of some use to you. Here is a link to a post I made during the Beast from the East /Storm Emma event.

    I'm afraid not but here's an interesting page on the UK for previous Easters (didn't want to leave you empty handed):

    https://www.booty.org.uk/booty.weather/metinfo/NFL/easter.htm

    I've calculated provisional IMTs previously (over a year ago now) for Easter Sundays back to 2007.

    You can find the chart of Easter Sundays and Christmas Days IMTs comparison from 2006-07 to 2015-16 here: https://www.boards.ie/vbulletin/showthread.php?p=103218509

    2016-17 figures can be found here:

    That would be difficult to do, plus I think it wouldn't be very useful as Easter isn't a fixed date in the calendar year not like say Christmas day.

    The years during WW2 had some very cold Winters as can be seen from the CETs (4 of the 6 Januaries had CETs of less than 1c):

    A front pushed northwards on 20 March 2001 into the cold air over the British Isles producing blizzards for some in the UK. It was too mild for much of Ireland and it was a very marginal situation as to be expected with the majority of frontal events. This brought rain to much of Ireland, not all that heavy in most places mind you, Rosslare had 19mm on the 21st. Ahead of the rain, temperatures were between 4-7c but behind it, up to 12 or 13c over Ireland. The rain turned to snow and sleet in localised areas particularly those over high ground in Wicklow and the midlands.

    Wow 1798 was old!!!

    I took all the -4 or more from your list and you could come to the conclusion that we are getting warmer! In the last 20 years of the 18th century there was 4 events. There was 6 events in the whole of the 19th century and only 3 events in the 20th century.

    Yes, there is no doubt we've had a warming trend following the 60s-80s as the 90s and 00s were both far warmer decades than any of those, but on par with those of the 40s and 50s which were notably warm decades in spite of the severe cold months such as January/February 1947, January 1940 and February 1956. The most notable trends of warmth lie in the Autumn and Winter seasons, Spring somewhat too but Summer is far more mixed and there isn't really a trend when you look at the details in terms of temperatures of comparing each of the decades named above. The 2010s (decadal IMT of 9.8c up to 2017) have went against this trend though with it being much cooler than the 90s (decadal IMT of 10.2c) and 00s (decadal IMT of 10.3c). It started off with the coldest year since 1986, 2010, with an IMT of just 8.7c and the 1981-2010 annual IMT average is 9.8c. 2010 as being a cold year should be no surprise because it consisted of two severely cold Winters, 2009-10 and 2010-11. The former was the coldest Winter since 1978-79 and the latter was the coldest since approximately 1981-82. Of course, the latter included the December to remember of 2010, this being the most severely cold month since February 1986 and the most severely cold-snowy month combined since February 1947. January 1982 had an extreme cold and snowy spell as can be seen from the CETs posted but the milder spells offset this for the IMT figure.

    With the methodology I and others use for long range forecasting or historical weather, it's quite easy to see why the 90s and 00s were far warmer than the preceding decades since the 50s and the 2010s going against the warmer trend. The 90s and 00s being warmer could be down to more active solar cycles, the AMO going into positive phase after being negative in the 80s and this is more for the 90s but lack of SSW events. The 90s had a lack of SSW events, just like the 2010s interestingly. From 1991-92 to 1997-98, there was not a single SSW event. January/February 1991 and December 1998/February 1999 were the only months to have one in the 1990s. Besides the December 1998 event (historically, December SSW events are not good for cold for some reason), each of these events were followed by some sort of cold or snowy spell including early February 1991 and mid-April 1999. If you do not know what this means in the case of lack of cold, with more active solar cycles making it difficult for blocking to take place over the Arctic Circle or around it along with no SSW event to obliterate, displace or split the Polar Vortex then it made it extremely difficult for cold to occur over Ireland during the 90s. Of course, when we got to solar minimum in 1995 and 1996, we saw some cold spells in December 1995, January/February 1996, December 1996/January 1997. May 1996 was the coldest on record and there was a taste of Winter in November 1996 also. To compare the 2010s, there has been a SSW event in February 2010, January 2013, March 2016 and two such events in February 2018. These were all followed by some cold weather at some point including March 2010 - the coldest since 2001 at the time, mid-January 2013, February 2013, March 2013 - the coldest on record for Ireland, late April 2016 bringing the latest cold and snowy conditions in the season since 1981, late February and early March 2018 followed by mid-March 2018. I'm telling ya, sudden stratospheric warming is a very interesting field to research and study. The Winter of 1962-63 was preceded by a Canadian Warming event (a type of SSW) in November 1962. Every year bar 1991 to 1993 and 1996 had an annual IMT of at least 10c in the 1990s. 1991-1993 were the years that followed on from the Mount Pinatubo volcanic eruption which had occurred in June 1991 - one of the coldest Junes on record. It has been established that global cooling takes place following significant volcanic eruptions such as happened in 1991 and 1992 following Mount Pinatubo's eruption which was the second most significant eruption of the 20th century behind only Novarupta of 1912. However, what remains a mystery is the effects of volcanic eruptions on the Irish climate and even the UK climate. Back in October, I began a research project in this area to see if I can note any cooling in the Irish climate at any point following significant volcanic eruptions using the IMT as a basis. The thread on my project can be found here where I've so far done one case study on Mount Pinatubo's eruption: https://www.boards.ie/vbulletin/showthread.php?p=106521949

    In this case study, I realised that 1991-1993 were some of the coolest years of the 1990s with 1996 included too but 1996 was the year of solar minimum so that was to be expected. 2008 was the only year of the 2000s with an annual IMT failing to reach 10c, this was also one of the years of what was a very long solar minimum and the most significant solar minimum since the early 20th century hence why there was a lot of blocking from 2008 to 2010 including in Summer and Winter seasons - every month of 2010 had a negative NAO and 2009-10 had the most negative NAO on record. An annual IMT of at least 10c in the 2010s meanwhile has only been achieved in 2011, 2014 and 2017. December 2010 was preceded by the eruption of the Iceland volcano Eyjafjallajokull in Spring 2010 which whilst not all that significant in terms of worldwide volcanic eruptions especially in comparison to those of Novarupta, Krakatoa, Mount Pinatubo etc but the volcanic eruption took place so close to Ireland affecting so many flights and there's some theories (including by myself) that say this helped to cause December 2010 be such an extremely cold month. To note, there have been quite a lack of significant volcanic eruptions as of the late 20th century which could also be a cause of the warming trend of the 90s and especially the 00s. The 2010s has doubled the number of cooler than average months of the 00s and we still have 21 months of this decade to go. We've had the coldest December on record, record low November and December maximum and minimum temperatures, coldest March on record and record low March maximum temperatures. What does the 2000s have to offer in terms of cold records? Absolutely nothing. The only month of the 2010s to have a CET of 18c or more up to March 2018 is July 2013 which had a CET of 18.3c. To compare, the 2000s had 2, August 2003 and July 2006. The 1990s had 5, August 1990, July 1994, July 1995, August 1995 and August 1997. The 1980s had 2, July 1983 and July 1989.

    Solar activity has been very low for 2018 so far and is at its lowest point since early 2010 perhaps or early to mid 2008. Solar minimum of this incoming solar cycle 25 is expected to be even longer and more extreme than that of 2008-2010. This means there will be months and months, days and days of spotless days on the sun which historically leads to blocking up over the Arctic Circle and this in turn leads to cold over the Northern Hemisphere with a particular emphasis on Europe. As a result, I think we will continue to see a cooling trend with more severe cold at times whether it'd be Winter, Spring, Summer or Autumn.

    The 9th February 1996 brought in a large depression from the Atlantic on quite a strong jet stream. The centre of this depression was as low as 970mb. It initially brought some heavy rain on the 8th, overnight into the morning of the 9th before leaving sunshine and showers. Cork Airport had up to 24mm on the 9th whilst parts of the southwest had around 20-30mm on the 8th overnight into the 9th.

    With such a deep depression as you'd expect, it was also a very windy day with with gusts reaching 70mph in parts of Munster.

    Fairly mild or close to average temperatures for the time of year between 8-10c.

    The end of March 2012 brought a spell of unseasonably warm weather that I think is remembered by the large majority here for being such a beautiful period or in some cases, infamous too because it was followed by Summer 2012 which in the UK was the second wettest Summer on record, behind only Summer 1912, exactly 100 years before.

    To remind you of the spell if you don't remember it, I am doing this post along with showing what happened exactly a week later on this day (3 April) in 2012.

    The end of March 2012 had the warmest period in March since 1965 (which like 2012 was a very poor Summer) with temperatures widely in the high teens and even low 20s for some. This was coming off the back of what had already been quite a warm March regardless of this spell and very dry too though not as dry as March 2011 for most. This was of no help whatsoever to reducing the drought across the east of the UK where they had so many drier than average months since January 2010 resulting in the worst drought since 1974-76 including East Anglia having its driest year on record in 2011 (in contrast, Scotland had its wettest year on record in 2011). Due to the ongoing drought situation here, hosepipe bans were brought in but nature has a funny way of evening things out because then the problems wasn't drought anymore, it was frequent flooding from April-December 2012 including the wettest April on record, wettest June on record, wettest April-June period on record :P. The month had an IMT of 8.8c (+1.7c above the 1981-2010 average) which makes it the warmest March on record in Ireland and the CET was 8.3c which made it the 5th warmest March on record in the series up to 2018 (goes back to 1659). In comparison, March 2017 had a CET of 8.7c which was the 3rd warmest March on record. April 2012 had a CET of just 7.2c which made it the coldest April since 1989 and the first time March was warmer than April since 1998.

    The main period of warmth began on March 22nd 2012 with high pressure just to the east of the UK and low pressure way out into the Atlantic dragging in a warm southerly or southeasterly flow.

    By the 25th and 26th, the 1035mb area of high pressure had parked itself over top of us bringing unbroken sunshine and temperatures in the high teens or low 20s. +8c isotherm up across Scotland, extraordinary for the time of year. Scotland's March temperature record was broken on both of these days (only to be beaten again on the 27th for the third consecutive day). Fyvie Castle, Aberdeenshire recorded 22.8c on the 25th followed by 23.2c at Cromdale on the 26th. However, as aforementioned, these records were beaten on the 27th with Aboyne, Aberdeenshire recording a maximum of 23.6c which to this day remains the Scotland maximum temperature record for March. Glenties, Co. Donegal had a maximum of 22.6c on the same day which made it the warmest March day since 28 March 1965 when Trinity College reached a maximum of 23.6c which to this day is the Irish March maximum temperature record.

    On the 28th, a weak cold front started to push into the north of the UK gradually going southwards to introduce much cooler air and cloudier skies but many enjoyed another beautiful day of sunny and warm conditions. As this front pushed southwards, a northerly developed behind it and high pressure attempted to retrogress out to the Atlantic.

    archives-2012-3-28-12-0.png

    Much cloudier for the north and east of the UK/Ireland on the 29th but to the south and west, more sunshine and warmth yet again.

    archives-2012-3-29-12-0.png

    Temperatures dropped like 10-12c widely and even more for some from the 25th-28th into the 30th and 31st March with the northerly. Continuing dry for a bit so pretty quiet and uneventful with temperatures now close to average for the time of year but they were set to drop further. Notice the northerly winds strengthening as days go on and low pressure starting to develop as the high has fully retrogressed.

    The 2nd April was a cool day with a lot of showery rain especially to the north and east of the UK. Temperatures were generally in the single figures. To think the week before hand, it was very warm in contrast.

    archives-2012-4-2-12-0.png

    Low pressure stalled to the southeast of the UK (this would become a familiar sight throughout much of April-December 2012 with a southerly tracking jet stream) forcing the winds to become a northeasterly to easterly direction on 3rd and 4th April bringing temperatures down to only 3-8c mostly. Some parts of Scotland had maxima of only 1 or 2c. Yes, you guessed it. Snowfall was recorded in parts of England and some of it heavy on the 3rd in Scotland. Even some parts of Ireland had the odd flurry on the 4th but rain on the 3rd.

    A follow on from sryan's post. Vids of snow UK 3/4 April 2012.





    The final one probably the best..

    I remember the March 2012 warm spell very well, both here and in the UK. It was amazing here but a little bit too hot for me when I went to London.

    This sounds crazy but I could swear that one year there was snow here in Dublin (maybe a snow shower, I don't know because my flight took off in the snow) at the end of March but it was warm in London. I think it was the 30th or 31st of March 2010 but I'll look at the charts later to confirm.

    Edit: Looks like those dates given above seem right but I don't remember it getting cold in London like the charts suggest,

    London wasn't even one of the warmest spots in March 2012, it was generally Scotland. You could not ask for a better spell of weather in March than that during that month as temperatures were so fine with unbroken sunshine, just wish that could have stayed with us during the Summer - one of the worst Summers you can find, 2012 is.

    You can see what 30/31 March 2010 was like in this BBC forecast:

    I have nice photos of the March 2012 fine spell on my DS which is nice to look at when you have weather like we've had in the past few days.

    London can feel oppresive because of the amount of people and traffic which probably explains why it felt so much warmer compared to here. i would say that those dates are correct. I was probably imagining that it was warm there because of how cold it was here. May 2012 also had a lovely spell of weather didn't it?

    I remember flying down the east coast on the afternoon of the 27th in totally clear skies. A slight inversion out over the sea, but from above it (3000 ft) I could clearly see Wales. Visibility at Casement was 45 km that afternoon and 40 km at Valley.

    Then Dublin ATC let me fly back in over the city at 3000 feet, well above the usual max 1700 ft. Quite a sight to see the big guys just to my north coming in to land at Dublin and me higher than them.

    As the Northern Ireland figure from the UKMO has released, I can say now that the IMT for March 2018 was 4.4c which makes it the coldest since 2013 and to no surprise, one of the coldest on record. 2013 was -1.1c colder. Fascinatingly enough, March was colder than January by a deviation of -0.8c. It also is fifth colder than average month in a consecutive run for the IMT since November, will April continue this trend?

    Sryan, do you know when the last time we had a March maximum of less than 13.9C was? It's 2C colder than March 2013's maximum so I wouldn't be surprised if it is near record-breaking cold. I can also see that March 2018 is the only year from the data you have so far that February had a higher maximum than March and wow, look at the 0.1C difference between the January and March maximum. Just shows how unusual March was.
