Model Output Discussion - the cold has arrived
Snowy L replied to Community Team's topic in Forecast Model Discussion
Yes hopefully a Storm Arwen scenario but with better blocking to follow. -

Well models improving with one half of the problem (stronger northern blocking), but we really need improvements on weakening the giant Mediterranean high developing next weekend. -

Doesn't change outcome on Sunday/Monday, but better Greenland heights and low oriented a bit better (ENE/WSW instead of NNE/SSW) -

This breakdown has a lot more support, but I wouldn't bet against models underestimating Northern heights either just like last week. Won't be enough to stop the breakdown imo but hopefully enough to not have a dartboard low to our Northwest not moving anywhere. -
Winter 2022/23 - Moans, Ramps & Chat
Snowy L replied to cyclonic happiness's topic in Spring Weather Discussion
Only the UK can get raging Southwesterlies from a completely dead Atlantic. Would be the perfect send off to 2022 after having a once in a decade 10-day December cold spell result in near zero snow for my area. -

Happens a lot ahead of an Atlantic low where there is widespread light snow. A lot of the time (and almost certainly this time due to lack of strong easterlies) it will just be light stuff giving a dusting but sometimes (1st March 2018 best example) it can give a better snow event than the actual Atlantic low itself. Given how dry this cold spell had been I'll happily take the former. -

Yes Atlantic low looking slidey again.
