First time in a long time id say the charts are looking a lot more spring like.  Pressure stabilizing to the south, less precipitation and overall calmer conditions.

WX temps - freezing weather in far N of Europe going, going, [nearly] gone by week 2. Generally mild and above norm temps for Europe in week 1, but in week 2 some real warmth developing over Spain and the Black Sea, but with some colder weather returning to W Europe and pishing down towards Italy, Britain on the fringe of this. Wet for Britain and NW Europe week 1, but for C/SE Europe week 2 and Britain becoming drier on the edge of some very dry weather moving N from Spain.

GFS Op - LP (Kathleen) moving N and deepening 950mb Rockall Saturday, filling but with quite a deep trough moving across Britain on Tue 9th. HP moving up from the SW for a few days at the end of that week, then after a brief interval with LP moving into the Norwegian Sea and winds in the N on Mon 15th, HP re-asserts itself and dominates Britain from Wed 17th - dry but maybe not warm as wind is still NW-ly.

ECM - like GFS but pressure recovers less after trough on Tue and Monday's N-lies coming more directly from a long way N.

GEFS - temps up - down - up - down to cool Wed 10th, then a solidly mild period lasting to Sun 14th all with good ens agreement, then returns to norm as agreement breaks up. Some rain around Tue 9th, rather dry at other times except for Scotland at first and NW Scotland more generally, even there dying away slowly.

Contrast the situation two years ago to where we are now where the ground in much of the UK is completely saturated after months of above average rainfall, even in the areas that are normally drier. I think we would now need an exceptionally dry & warm period for the rest of the spring and going into the start of summer for the ground to get anywhere near the level of dryness there was two years ago.

That is well below what it should be at midday for the first week of April, even in Scotland. It is forecast to get milder though over the weekend up here.

It reached 19C in one location in NE Scotland back in January, around the time of one of the storms I think it was. There was a very mild sector over the UK or at least some areas at the time, IIRC. I think how far south the wind is originating from has a lot of say in how mild/warm it gets too.

I imagine the vast majority of us here don't want a repeat of 2022 (I certainly don't). That said, with so many flood warnings in force across the country right now, I think a dry spell regardless of prevailing temperatures is needed PDQ.

WX shows the current 'layered' temp profile (freezing N Scandinavia, mild/warm in Med, a mildness gradient in between) changing in week 2 to one in which rather cooler weather spreads south over W Europe balanced by heat over W Spain and the Urals. Rain for the far NW in week 1 (Ireland to Norway) decreasing in week 2 though not entirely absent; in week 2 the heavy rain is for the Alps and C/SE Europe.

GFS Op - Storm Kathleen drifts N-wards to Iceland, filling, but generating a local 'runner' whistling across S England 990mb Tue 9th. Then a period of mild SW-lies controlled by HP 1030mb over Biscay to Sat 13th, terminated by LP moving past Shetland to Scandinavia with winds going round to the N by Mon 15th. HP then forms a ridge from Greenland S-wards through the Atlantic quite close to Britain though possibly cool but a new development, not shown yesterday, is LP originating Faeroes Thu 18th running south and deepening to 995mb Wales Mon 22nd (formerly the Atlantic HP hung on)

ECM - very much like GFS, perhaps LP in Atlantic closer after Tue 9th so winds are stronger and more W-ly than SW-ly.

GEFS - temp dropping in stages to cool by Wed 10th the recovering to mild (very mild in S) until Mon 15th at which point a sudden drop to norm, all with good ens agreement. Mean then stays near norm as individual runs spread out with op on the cool side.  Occasional pulses of rain to Wed 10th then mostly dry in most runs, some peaks in a few ens members ca Thu 18th.

Still so early in spring though, and the lack of posts from the snow and cold hopecasters is a refreshing reminder that winter (even though it’s not cold or snowy anymore, anyway) is as far away as ever.

WX temp charts haven't really picked up on the current high values noted in W Europe implying only a brief warm spell (the charts show a weekly average), Week 1 charts show warmth persisting only in E Europe, across Ukraine and of course the Mediterranean shores. NW Europe as a whole is mild and a little above norm. Week 2 charts look much like yesterday, freezing weather breaking up into small patches in Scandinavia, warmth moving N-wards over Spain and Ukraine, while a push from the general direction of Iceland brings cool weather to Britain and NW Europe and restores freezing weather to the Alps. A large area of very dry weather over S Europe in week 1, with some rain persisting in NW Britain and Norway; in week 2 the latter fades and heavy rainfall appears around the Adriatic.

GFS Op - storm Kathleen moves NE and loses its identity in the Norwegian Sea while a small but potent secondary LP 995mb moves rapidly up the Channel Tue 9th bringing in NW-lies briefly. HP then develops 1030mb over France and extends E-wards but with LP never far from NW Scotland Britain lies under SW-lies through to Sat 13th. Pressure then drops over the Baltic bringing NW-lies to Britain (yesterday it showed more of a direct N-ly) but by Wed 17th Britain is back under HP from the Atlantic. LP then tries again Fri 19th, arriving Cape Wrath from the N 990mb but after a brief visit to the N Sea is pushed back N-wards by HP 1030mb Germany Tue 23rd with S-lies for Britain.

ECM - Similar to GFS but after Sat 13th the Baltic LP is deeper and closer but not displacing the Atlantic HP, so expect N-ly gales for the E Coast with a greater pressure gradient.

GEFS - temps dip to cool Wed 10th soon resuming very mild (6C above norm) until Sun 15th/Mon 16th when a sudden drop to cool in all ens members (good chance of snow in the N at this time), mean soon returning to norm and staying there to Tue 23rd in the middle of a moderate spread of outcomes. (Not as cool in week 2 as suggested by WX above). Scotland and the W get heavy rain on Tue but otherwise only small amounts of rain and that not in all ens members for the next fortnight.

Some very tenuous signs of mild improvement. Looks drier for the south as pressure builds across the continent. Unfortunately it then ridges up toward Greenland and plunges us into a northerly. All at range though and nothing like cross-model agreement. 

Someone will say if only it was January

No real change in WX temps today. From yesterday:  Week 1 charts show warmth persisting only in E Europe, across Ukraine and of course the Mediterranean shores. NW Europe as a whole is mild and a little above norm. Week 2 charts look much like yesterday, freezing weather breaking up into small patches in Scandinavia, warmth moving N-wards over Spain and Ukraine, while a push from the general direction of Iceland brings cool weather to Britain and NW Europe and restores freezing weather to the Alps. For rainfall, as yesterday, week 1,  some rain persists in NW Britain and Norway; in week 2  heavy rainfall appears around the Adriatic but a great improvement for Britain with some very dry weather working in from the SW.

GFS Op - small LP running across England tomorow (Tue) 1000mb then pressure rising 1030mb France with SW-lies for Britain slowly going round to W-lies by Sat 13th. Low pressure running SE from Iceland to Baltic then turns winds to the NW briefly (not as much N-ly as shown yesterday) but HP re-establishes, this time over Britain, in place by Tue 16th and intensifying 1035mb Scotland Fri 19th before moving on to Norway Wed 24th and allowing NE-lies to affect E England with shallow LP near Denmark.

ECM - as GFS until Sat 13th. Then the LP running SE is closer, takes a swipe at NE Scotland as it goes by, more definite N-lies to follow, and pressure then rises only half-heartedly with a centre1025mb Brittany Thu 18th and W-lies for Britain.

GEFS - temp profile much as yesterday, dip to cool Wed 10th, a swift rise to mild (very mild in the S) lasting to Sun 14th when sudden decline to cool, all with good ens agreement. The mean recovers to norm but in the midst of a spread of outcomes, op mild and control cool. After the next day or so (when heavy rain in Scotland, showers in S), very little rain, perhaps a bit more in a fortnight's time in the south, but W Scotland and N Ireland only slowly become drier..
