Not bad on GFS- depends what you want from t, I suppose but it's a far cry from the endless 5C+ uppers dross of December. This wintry map is only a week away. When does FI start- is it post 120?

13C uppers over Brighton. High for early Feb.

Can anybody tell me where the PV is on this chart? Is it that little low E of Canada?

A true wintry blast now starting to feature in the extended output. Will this be winters last chance saloon? It would tie in with what met office have been writing about since November.
Those hoping for an early spring might have to keep the gloves hats and scarves handy or a while yet.
Cool, then cold then even colder as we approach mid Feb.
I think the switch is now showing.

Not sure about winter returning but I am more concerned about that nasty secondary low showing on the GFS for February 6th. It's still 6 days away yet but if those charts verified the south would get a real battering.

I think it will be next week when the first signs may start to appear in FI. 


As Ive said before, one week of cold with a fall of snow that hangs about for a few days would rescue this winter for me from the reject pile.  The modal average for days of laying snow is zero, zilch, nothing for many areas.  In other words - a snowless winter, whilst not the norm, is the most common outcome in terms of days of laying snow.  Mean averages are dragged up by freak years such as 2010, 2005 IMBY, 1963, 1979, 1985 etc....My point being, that pre-conceived expectations perhaps should be set in advance at the modal average outcome (speaking from a southern urban perspective), and that any advance from zero for snowcover days in a winter is a bonus...


The models continue to show zonality as the favoured outcome, with just one breakaway option popping in this morning.  Plenty of time for this to change, and as an illustration, there are another 40 GFS runs between now and February 9th.



 


On the other hand, IF there is to be no cold spell in February, March can deliver both pleasant spring mildness and sparkling sunshine, as much as the earlier half can deliver the coldest weather of the winter period, March is often a fascinating period for model watching.


From a model watchers point of view, it really can be win-win.

One thing about which there is excellent model agreement is the worryingly strong winds for northern parts on Monday night. Another sleepless night wondering about power outages and more weather damage for a swathe of the country.

I wouldn't rule out another red warning (for the Western Isles)

Massively unsettled sums it up but you can certainly see how a significant cold spell could turn up with charts like the day 10 ECM.

Frankly, when even the coldest ensemble members only bring highs of 3C or so for London, it's really not much to get excited about if you live down here.


My benchmark for spotting cold spells hasn't changed: it's still several runs in a row with multiple -10C 850 members, along with some showing ice days. The output at the moment doesn't meet the first crtieria, let alone the second!

GFS control. Once Imogen clears, we have a shot, and it maybe the last hurrah for the season

Poor runs again but do I spot spring in the air on the GFS 06z for St Valentines day?

High pressure to the south east with a mild feed would be most welcome so I can get out in the garden and forget this dreadful winter.

I still can't see anything to change my thoughts that we have a robust form of cool zonality dominating for another 10 days with only transient HLB.

Does anyone know when was the last time that southern England was under 500hPa heights below 500?  The T+216 charts are pretty close.


Cold, wet and windy is better, at least in terms of variety, than the slug-fest that was on offer not so long ago.

Since it's in deep FI, it's not really worth losing any sleep over anyway, IMO.
