Yes a proper lazy wind forecast on Monday.


 


I must say though I do find it bizarre how the air can blow across the warm Atlantic for a couple of thousand miles and still give temepratures close to zero in Scotland, and yet on the relatively short track across the UK it manages to reach 8 degrees by the time it hits the south coast. Where does all that heat come from?

Anyway largely irrelevant as unfortunately I cannot see it working out like that.  GFS probably overdoing the cold air, look at ECm for the same period,  nowhere near as cold.

As much as you tend to think the air has travelled around the LP. As its an area of low pressure its effectively sucking in air from all directions including its southern flank. HPs are pushing air our from their cells and vice versa for the LP. So to the south of the UK their cold air is mpre modified atlantic air, where as the air to the north is likely to be more of the polar variety.

The FI ensembles of GFS are showing some chances of a high to NE / Center ed over the UK. The control run shows it nicely, with a mean showing high pressure of sorts!

Yes - look upwind too, the jet is weakening by the 20th - even with amplification from the steep temperature gradient off the USA, which could be the first chance a block could form and stick for more than a couple of days, without a atmosphere stripping solar wind like jet stream blasting us like we are rioting in the face of a water cannon. Likely cold spring to freeze those early flowers - primroses are competing with my snow drops and daffy are looking very hopeful!! It's only Feb 4th - what the proverbial is going on with my garden. Day lilies popping up like mushrooms after a manuring.

It may be late and naff, but I need a cold snap like the desert needs the rain!!

The Wednesday storm doesn't really develop as much on the 12Z GFS but there is another monster a few days later, reaching 930mb to the north of Scotland.

This could well be the most interesting spell of the winter coming up. I think there are too many options for it not to be. In the past this type of thing often causes a major reset of patterns so anything is possible after the storms pass.

GFS 18z Aaaaaaaaaaaaand it's back on again for my neck of the woods with 100 mph gusts in the small hours on Tuesday night - comparable with the Great Gale of Oct '87.

Still room for adjustments of course but that's cutting it a bit close now.

If it’s still there on Thursday night then I might take it seriously.
Having said that it’s impressive to see 100mph gusts being modelled across lowland south UK - that’s quite rare.

At least if it does impact the south, tv news outlets might cover it.

Wow - this morning's GEFS down here has one of the strongest signals I've ever seen for exceptionally mild conditions as we approach the end of winter:

http://www.meteociel.fr/cartes_obs/gens_display.php?x=&y=&run=0&ville=Londres&lat=51.5085&lon=-0.12574&runpara=0&type=6&ext=1 

It's very unusual to see such strong agreement at the 10 day+ range. Not that it counts for much, as we all know ensembles can turn on a sixpence, but it'd be sod's law if it happened!

GFS has calm HP to Fri 7th, then gales from Sat for the whole week at first from SW the NW and back to SW again (Meto widespread warning Sat/Sun, probably more to come). Unlike yesterday, the dominant LP stays up to the north until Thursday, and only then developing more local and closer centres, notably on Fri (950mb Rockall) though ECM has this a day earlier. HP back in charge from Mon 17th to end of run on Fri 21st, mostly to the E/SE and bringing up warmth from the south.


GEFS shows cold and wet for week from Sun 9th, good if brief chances for snowfall (a dead cert over the hills, I'd have said) then remarkably mild from 15th (a couple of days later in Scotland)


Jetstream running strongly and directly across the UK from Sun 9th for a full week, then slowly weakening and breaking up into loops by Wed 19th - by then positioned to N of UK but never really going away.


The pptn http://www.wxmaps.org/pix/prec4 follows the jet, most of the UK wet at first, then in week 2 restricted to north. The associated temp chart has amazingly widespread positive temp anomalies for N/central Europe in week 1, up to +8C in Scandinavia.

While both ECM & GFS are showing next week's affair a downgrade and put back to Thursday, it could still flip back. Sadly it does mean the whole thing remain as a NAO+ state for as far as the eye can see. Oh well, keeps heating costs down.


i'm not too overly concerned about this weekends winds with 40/45 mph and up to 70 mph gusts as those are not truly exceptional values for this time of year. Most of it will be coming in from the SW so I'll be relatively sheltered by the nearby hilly built up area anyway.

Overall it was the 7th warmest, or joint 15th warmest if you go by CET.
