As things stand this looks ideal for a snowy spell - Temperatures of +1c or +2c max by next Saturday with low pressure to the south across Bay of Biscay and Channel could bring some sleet/wet snow inland? - Won't take this too literally because we have all bee let down before:

I wouldn't base a forecast for a week ahead on just one run Tallyho, as those charts will doubtlessly change again over the next few days.

If you get your hopes up based on them then you're just setting yourself up for an epic fall!


No, you should instead rely more on the high-res charts (available on Meteociel) and especially high-res models like the Euro4 and Arpege and NMM - these still aren't perfect but they're a damned sight better at it than the regular old GFS.


(And the time to get excited in my experience is when it's persistently shown at short-range on the Met Office local forecast output. That and having non-disputable snowworthy conditions, ie sub -10C at 850 with a moisture / convective source).


There could well be some surprises later this week but I for one am not even expecting as much as a flake of sleet where I am.

0/10 this winter so far.

From IF


Temperatures are about to start a decline to below average and expectations are for quite a few weeks of that situation remaining, with cold/bocked weather dominating. It could last well into March. Longer range products have only just started reacting to the MJO phase 7 (which tends to have instantaneous response in outcome here) due to lag. Now we can see the direction becoming clearer in GloSea5 and EC Monthly, we await the operational model centres to catch-up. Storm track is expected to become ever more southerly in next 1-3 weeks, with inherent prospect of these passing to S-E of UK and resultant risk of wintry hazards. It's total chalk and cheese change versus winter so far and evidence is now compelling for most protracted period of below-normal temperatures seen for some time. It matches exactly the UKMO Seasonal Team assessment for this winter, but only now is the model evidence becoming well aligned. 


IF Again


EC-EPS run below average all the way to end of run (see below, Reading shown). Considering too how all 51 ENS members sit in a single cold cluster by 6 March (see below), the support for a lengthy period of NW-N'ly dominated flow, as per GloSea5 and EC Monthly, is starting to get reflected now in other products.

Chart of the day probably goes to the ukmo day 6 but it's still borderline snow for the south. Still we're in with a chance which is better than its been for 99% of this sorry excuse for a winter.

TBH after the winter we have just had I will gladly take a week or two of cold, dry weather with night frosts and sunny days.

It would mean I can get outside and prepar for spring and summer, I am sick of being stuck in the house like a hermit.

A cold end to the month will also scupper the mildest winter on record, the last thing we want is GW bores gloating about a record warm winter!

In the north this winter since Christmas has just been rather mild than anything exceptional with some frost and snow, winter 1988/89 was far warmer overall than this winter north of Manchester.

Also, if it does turn cold for the next 4 weeks then it will be hats off the the MetO for it's seasonal trend although I suspect they thought colder weather would arrive a couple of weeks earlier.

But for now it's buy, buy Uncle Barty and that dreadful mega zonality.

I'm pretty sure that if this February had turned out to be as mild overall as Feb 1998, as predicted by some people here a month or so ago, this winter would almost certainly have beaten the record of 1868-69 as the mildest winter on record. There has never though, as far as I have seen, been any suggestion from the model output over the past few weeks of this month being like February 1998, at least not with any consistency.

A repeat of the spring & summer which came later in 1995 would be most welcome!
