Winter v.2 is on the way!
Hi all,
Just trying something here...
A pretty dramatic air mass change is on the way for the British Isles. I hope you enjoyed a bit of warmth the last few days, temps at Foxley here reached 22.3C, the warmest March temperature I've recorded since I started my weather station in Dec 2011.
For some places this is was the warmest spell of March weather since the late 1960s!
A weak cold front will cool things off a bit on Thursday through Saturday, with a brief warmer day on Sunday...but the real fun comes on Sunday night through Tuesday as an Artic Maritime Airmass pushes southwards across all of Britain, plunging us back into winter-like conditions. Could be some wintry showers/snow in place, with daytime temperatures by Monday struggling to get much above 5C. Check out the charts linked.
I think this should let you comment, so ask questions if you have any.

So we are talking about severe temperature differences mixing in the upper atmosphere? Thunder and lighting ? Or not so likely .
ReplyDeleteLooking at different model predictions chance for snowfall is also there from Sunday-Monday onwards, is it actually likely to happen?

ReplyDeleteIt looks like it might be ? We will be completely covered by the Airmass and it looks like we will be fed continuous moisture from the cold polar maritime Airways for a few days? Snow snow snow!
ReplyDeleteThe risk of lightning is pretty marginal, there looks to be about 300 j/kg of CAPE (in the lowest levels), and the showers will be quite shallow (generally up to around 650hPa). But yes, looks like a pretty good chance of snow from Monday morning into Tuesday, although nothing any where near what we saw back in Feb.
ReplyDeleteSnow this morning in Essex - typical bank holiday weather. Next door are still having a BBQ
