Little low for tomorrow looks like it has been nudged a bit further north, with a warm sector making it up to Morecambe Bay and across to Bridlington. Could still be some wintry weather over high ground as the system moves in tomorrow morning, as well as more generally over Cumbria, NYM and the Dales if this is the track the system takes.

GFS 12z out to t222 and all the way through the run the Euro/North African High is absolutely dominant. It's really difficult to see how it is going to get shifted anywhere in the near future, at least based on that run.

You look at the GFS and it is definitely not zonal, very meandering if anything.

So an ice day for some northern parts, a snow risk for parts of the middle and continuing mild in the south seems to sum up the next day or two.


So, a chilly few days for northern parts before the milder westerly regime strikes back once more. Based on uncertainties beyond the next week to ten days it is way to early to write off December based on anything beyond guesswork and flimsy extrapolation.

December is not written off as far as I'm concerned.  I'd take mild all month if we could have frost and snow at Christmas.

For anyone to write off the rest of this month when we still have 20 days to go would be unwise, to say the least. As I said earlier, if we were now inside the last week of December having had a mild, zonal month and the models were showing what they are for next week, then yes, OK. But often forecasting one week ahead is a tricky business with our climate, let alone three weeks.


Andy Woodcock once famously wrote off virtually a whole winter month based on what at the time seemed like poor model output from a cold point of view, and was later made to eat is words big time. Regardless of my own preferences, I would hate to see this happen to anyone else now!

No comments on the 12z ECM???
Nope. Thought not as it shows unrelenting zonal mild mush as far as the eye can see.
Denying that December is likely to be a write off is denying the seemingly inevitable. There is no doubt as far as I can see, and so odds on a record mild December in my view.
It is a dreadful ECM for cold and continually ignoring run after run of these operational Is just mild denial but I do understand why people refuse to believe it - if things can't get worse then hope must remain I guess.
It is only one month and things can change, but not for the foreseeable.
Until I see even the remotest sign of blocking or the Euroslug dissipating, I can't see any way out of this AT THE MOMENT.
We desperately need a pattern change but when and where that will come from is beyond me.

Don't know about that, winds will be light so evaporational cooling will, likely, take over. I suspect the likes of leeds far from seeing sleety flakes will see a covering of wet snow.

having said that, I don't think I remember the model output looking so bleak... Maybe 2013/14. The atmosphere can't help but to pull up mild SWesterlies.
