May shocker: strong winds, squally showers, even the potential for wintry showers

Kermit.de.frog · 04-05-2021 2:29pm

Had quite the epic hail shower about an hour a go. Sunny and pleasant 6.5c at the moment.

11c in Cork now, nice and sunny. But the wind outside would cut you in half. Ordinarily this would be excuse enough to head somewhere (anywhere) nicer but not this year.

“Hold firm” Chris we’ll get out of here allright vaccines and digital cert have to rescue us. My car showing the temp as 4.5 degrees a few mins ago during a shower.

Would check May 1996 for temperatures, in the CET record that's the recent cold one (9.1 vs their recent average of 11.7). In our contest, the IMT for five locations has a May average of 11.0 for 1981-2010. April came in one degree below normal (7.4 vs 8.4). But for the CET it came in colder than that (6.4 vs 8.5). So parts of Britain were in that coldest in 35 years region (1986 was 5.8).

Lovely winter scene here in Newcastle Dublin

The national mean here in that month (May '96) came in at just 9.0c, which is 1.8c below the 81-10 average. The opening days of that month were particularly grisly, with the maxima not breaking 9.0c in parts of the north and east. I don't remember much about this month except that I do recall seeing dry snow falling on a day something like today.

Mean SLP pattern and 850hPa temp anomaly for the month as a whole. Unsurprisingly, it doesn't look to dissimilar to the forecast pattern over the next 7 days or so.

Hefty hail shower just passed through Dublin 16 and we had a temporary white cover.

Looking ahead, tomorrow the coldest uppers arrive over Ulster, 522 dm thickness reaches approx Leitrim to north Leinster and stays there most of the day so in parts of NI as low as 519 dm, 850 mb temps near -6 C, any higher elevation showers could turn to snow or ice pellets.

A bit of a secondary push of cold air on Thursday will at least keep it well below normal to Friday.

Any optimism about temps this weekend looks a bit premature to me, it will certainly try to recover in the southeast and may reach 14 or 15 C there, but the way this next low is coming in, warm advection is very weak and the overcast will kill it off, with a steady rain setting in later and into Sunday. Then it's another three cold days after that.

The GFS gives some promise of a brief warmup around Thursday 13th and Friday 14th where it could be near 20 C. Then there would be yet another cold spell developing in the following week as the winds turn northerly again.

Overall I can't see the mean temperature getting past 10 C at any point before the very end of the month. It may reach 9 C briefly in that warm spell then fall back into the 8s.

Hailstoning in North Donegal as I type.

And pretty windy too, not a patch on yesterday but still blustery.

Tyrone212 · 04-05-2021 8:01pm

A bit of sleetyness mixed in at the end of the last shower.

Hail?

Bought Kiwi plants a month ago and thought I would get them planted out. They are not doing well in their small pots. Think will have to bite the bullet Friday and get them out, hopefully last real frost on Thursday night?

Oneiric 3 · 04-05-2021 9:20pm

I kinda got to wondering if this ongoing northerly stream has anything to do with (admittedly. very small) ongoing eruption in Iceland? I do remember back in 2010, that the much larger eruption there seemed to coincided with an unusual amount of northerly winds around this time of the year as well.

External Association · 04-05-2021 9:40pm

I remember May 1996 quite well. When you'd be out from 7-9pm it felt like twilight on a cold northerly with frost in the first week of March. Your breath holding visible in the air.

The June Bank Holiday weekend was very cold too. That summer was poor overall bar a warm week mid to late June, 27C in Shannon and a warm week mid July. August was cool and very cloudy.

Tyrone212 · 04-05-2021 10:31pm

Sleet and pockets of snow showing up on netweather radar.

Gee MT! Cheerful soul! I hear there is snow in parts of Canada...

Actually it is not the temp that is so damaging for my needs (as long as there is no frost) but the high winds. As a serious gardener/grower. My home is small and currently the bathroom is stacked with seed trays taking refuge from wind scorch. Little is germinating.. And the lack of rain until now... Even that first shower saw wee green shoots appearing to gladden my old heart..

As we are of course cut off by the gales also, growing is even more vital. Even the chickweed is not up yet. ( good vitamin- rich eating is chickweed)

yeah i remember ome of these years from the GAA games I know they are only saturdays and sundays but give a good snapshot of weather week to week. i remember that year well because meath won sam. leinster final day v dublin in last sunday in july was a downpour , the kerry v mayo semi final was wet day to and the other semi final meath v tyrone was overcast and cool. i remember the first meath v dublin game in 1991 was june bank holiday sunday very cool and windy as was the replay the following week and third game was in pouring rain, June 1991 must have been a very bad month.

Down to -2C one night in early June 1991. Very cold start. Even the 4th Dublin v Meath game on 6 July was very sunny but only 15-18c.

The summer took off on Saturday 10th August when my Laois lost to Meath in the Leinster final

Mid 20s late August and 28.4c on 5th September 1991 in Valentia. The weather broke shortly after mid September 1991.

Kilkenny v Wexford hurling 1996 first round on June Bank Holiday Sunday was a cold day. I remember the rain Meath v Dublin Leinster final, 10pts to 8pts I think?

Got ridiculed for telling friends that I remember a decent frost in June. Would have been early 90's so possibly that time.

If I recall correctly July is the only month in Ireland without a frost recorded at one of the weather stations?

Donegal Storm · 05-05-2021 12:04pm

Plenty snow on the hills in Donegal today

In the North the record low for July is -1.1 in Tyrone and -0.3 in Longford.

Met Eireann has the all time July low at -0.3c in Longford:

Ground frosts however, although rare, are not unheard of in July.

-5.6c record low for May

Any chance of us hitting that?

-3c tonight ...maybe -4c in Mt Dillon/Markree or Mullingar/Dublin Airport

I was wondering if the weather had anything to do with the eruption of La Soufriere in the Caribbean which is more active than the one in Iceland.

God only knows but certainly a lot of ash thrown into the atmosphere from that series of eruptions a couple of weeks back.

There was a few nights heavy frost last May, burned the leaves off potatoes, and young trees around here, even damaged a few acres of Norway Spruce I'm growing, which is supposed to have good resistant to late frosts

wow your good! yes i remember being at wexford v kilkenny i thought it seemed like mid may all right everyone in coats and jackets. i was at it because Meath played Offaly in the first game in hurling , Meath put in a really brave perfermonance i think it was 2-12 to 2-18. yes the dublin -meath leinster final was played in a downpour and we got a famous breakthrough victory, we also had a famous THE breakthrough victory over dublin in july 1986 which was on a downpour as well. the famous 1986 summer!

i think the Laois v Meath leinster final was wet overcast day on August 10th 1991 too. the roscommon semi final was played in beautiful warm day and all ireland final v down where our heart was broken was also lovely and warm. That game still haunts many meath fans....
