Looks like the MetO have belatedly realised there will be damaging winds this afternoon - the yellow warning has now been extended to cover Kent, East Sussex and so forth. Better late than never, I guess, although as I said yesterday... a lot of people will be caught out by this!

Wow.
We need to take this seriously. Possible disruptive snow event around the 3rd.
Lots of factors need to come into play here, but potential there is.

All models are going for some kind of snow event in about a week somewhere.

Historically the snow risk used to trend south over time, but it has not done that this winter at all so I'm not going to count on that.

In the end what I expected to happen did indeed happen - MetO raw now has 51 as the strongest gusts (in an hour), GFS ended up at 52. The highest gust recorded at the yacht club a few miles away is 48, but it's relatively sheltered from the SW/SSW.

I'd love to know why the MetO raw so predictably undercooks max gusts. It's done it half a dozen times over winter, and now spring - with usually a whole day of "ninja upgrades" as the winds approach. Similarly GFS always seems to go too high, backing down at the last minute...

GFS ensemble mean is going for lying snow north yorkshire northwards Wednesday-Friday. Amounts vary but typically 1-3cm lower levels, 2-7cm hills, 10-30cm mountains. This would be causing alot of excitement if it was January. Pretty good for an ensemble mean.

WX temps downgraded for spring warmth since yesterday, only appearing around the Black Sea/Caspian and extreme S Spain. Otherwise little change over the next two weeks - cool/cold for Scotland and N Scandinavia, on the cool side of norm for the rest of NW Europe. Rain for Atlantic coastal countries incl Britain week 1, decreasing week 2 and mainly affecting N Spain/S France/Norway with Britain in a damp but not soaking patch between.

GFS Op - current LP continuing its tour of W Britain while filling until Mon 1st when combining with LP in Baltic to form an E-W trough from mid-Atlantic to Sweden. Within this trough distinct LP centres come and go; for Britain, Ireland Wed 3rd, Scotland Fri 5th, Wales Sat 6th, Channel Mon 8th, all 990-1000mb; rather cool NE-lies predominate in the N, milder but not much in the S. From Wed 10th zonal W-lies though rather cool and a brief intrusion of LP 1000mb Sat 13th as it zips locally across Scotland.

ECM -agrees with GFS but with minor differences in LP centres within that trough; Cornwall Wed 3rd, Scotland Sat 6th. The last frame Mon 8th turns the trough into two large areas of cold LP, Greenland and Norway, Britain in a weak col between, with the Greenland LP threatening to extend towards the Bristol Channel.

GEFS - in the S, good agreement of ens members on near-norm at first becoming mild Fri 5th; then a second mild peak for the main cluster is spoilt by a very cold op run before some agreement on near-norm again from Wed 10th. Rain frequent from Mon 1st to Wed 10th, a little drier after that. Scotland (& to less extent N England) temp on norm to Tue 2nd then a big contrast with the S as most ens members dip 6 or 5C BELOW norm until Fri 5th, then the second mild peak and return to norm as above but less agreement. Periods of rain in the same time frame but more sporadic and heavier  when they do occur, snow looking likely in places 3rd-5th.

06z Op run today shows quite another snow event for the south and west @ 276z: - If only....it was in winter. More evaporative cooling? Response to the SSW still?

Easter weekend doesn’t look too bad for many, I’m more bothered by the prospect of wintry weather in the following week up here.

In fact, I've lost track of how often we have gone into BST only for our weather to then turn colder with wintry showers, or possibly even some actual snow.

Given that we had very little in the way of snow during the winter, the weather gods will have had a real cheek if that ends up being the outcome next week as a lot of the output is suggesting.

Seeing the 12 GFS run showing the Atlantic throwing low after low after low towards the UK as we go into the first week of April is testing my patience - as if I haven't got bored of this seemingly endless Autumn months ago. The latest UKMO run offers a slightly better picture - at least as far as here at the SE of the UK is concerned but our maritime-type climate is such a drag most of the time.

Part of me has been thinking that the wet spell which has been ongoing since last autumn has been payback for the dryness that southern areas experienced during the summer of 2022 and the 2021/22 winter. That very dry spell seemed to mostly be concentrated on southern parts as I don't recall there being any prolonged dry spells anywhere in Scotland during the first half-dozen months or so of 2022.

As you say, this wet period nicely balances some of the very dry conditions of previous years - it remains to be seen when the lurch back to prolonged dry conditions will occur! (Obviously I'm hoping it's not during summer, as I enjoyed having a green lawn for once... it's rare to see that through the whole summer down here).

FWIW the "final warming" is going to be late this year. In theory that means an unsettled spring, in practice? We'll see...
