More importantly, initiation now creeping towards the day 10 marker. 

Still all looks to be coming together for an early Jan cold spell...

From December 27th 2020, zonality will be banned from mixing with the UK. We appreciate that this may come as a shock to younger people and old Uncle Barty. This ban will last for a minimum of ten days.

That is a completely disorganised PV with a whopper of an Aleutian low. Good signal for SSW.

Of course things can go wrong, but we're about as loaded towards a cold outcome as we can be at this range.

Nothings ever nailed in meteorology but when you’ve got all of the big players all singing from the same hymn sheet for the winter ahead then you have to have a little more faith than usual. Of course Ian could well be proven right but the NH profile is nothing like it was in 97.

ECM will be interesting to see if there is any westward influence of the high. Runs off slightly more current data so would be a good sign if it does

January will IMO buck the trend of recent January's and cone out with a below average, possibly well below average CET. I expect it will be quite dry but all areas will see at least some snow.

Make the most of this mild December because I foresee a severe January ahead.

Guys let’s get away from Ian bashing, actually what he has said on this thread is reasoned and quite factual.

In the meantime some interest for coldies, it’s all up in the air again as is usual with most UK cold spells/ snaps

http://www.wetterzentrale.de/maps/ECMOPEU12_192_1.png  The outcome could be mild and mobile but it could very well be something much more interesting. I could of course ignore all that and bet on the UK default climate pattern, but that doesn’t need any analysis.

I always find it frustrating that anytime a half decent storm low develops in the Atlantic, a half assed block always sets up in just the right position to push it off course. A block that will bring nothing of interest in itself, but just strong enough to steer anything of interest from the Atlantic away.

ECM brings snow to many as does the UKMO however at this early stage & with ~ 540 thicknesses then its all a bit marginal but with scope for improvements- Ideally in the form of a bit more 'continental feed' underneath... SE is much much better than SSE in this scenario...

Seems there are a succession of Atlantic storms lined up for next week, but not sure which one or two have our name firmly on them.
Could be headline makers in there, certainly the coasts will take a battering with coastal erosion and over topping.

Come mid January when we're still enduring Atlantic system after system, rivers are beginning to burst, and the best cold has been a few frosty night's inbetween, I bet you'll be bragging about how you had predicted this all weeks or months earlier 🤣😋

That would be good enough for most Steve as we all know we dont need massive -ve 850s in s/e feed its happened before we just need more of them to grow.

The chart below shows the rainfall pattern for the next 10 days across the UK, and shows how wet it is generally expected to be.

However, you will probably have noticed in that map that the driest area appears to in SE Scotland once again.

One thing which I have kept on mentioning in both the Current Conditions thread and the Precipitation Watch Thread is the manner in we are just not getting as much rain here in this part of the world just now as what the rest of the UK appears to be getting according to what everyone else is reporting on those threads, even though we are getting more rain than what we have been getting for a while. The above chart shows clearly, how this is likely to be the case for the next 10 days as well, resulting in that rainfall gap between here and the rest of the UK getting even bigger over that time.

Yet we in this part of the world have one of the biggest rainfall deficits in the UK to have built up over the course of the year. Last month was wetter than average here, though not by much and whilst the rest of the UK is running much wetter than average just now, our rainfall totals during this month so far are running at no more than average. This means that whilst the rainfall deficit may well be getting made up in the rest of the UK, that just isn't happening here in SE Scotland, and doesn't look like happening during the next 10 days either, going by the above chart.

I therefore find it weird that mother nature appears to be picking on this area of the UK in particular, for not giving us as much rainfall as the rest of the UK although I'm sure than anyone who is more knowledgeable than me, will be able to give a very good reason for why this is the case.

Have to say I'm shocked at some of the posts on the other side about a possible snow event towards the end of next week. Two golden rules for this to  happen (away from the highest ground ) -

  • cold air has to be in place first before the PPN arrives
  • if it isn't then colder air has to be pushing back against the PPN to turn it to snow

 

Whatever the wind direction, none of the models show the above happening.

 You’ve been in the game long enough to know the big 3 +144 charts are as enticing as they come for the UK. Atlantic is always odds on but at +6 days any adjustment west would bring a snow event. ECM also holds the block to the NE as the Atlantic fizzles....
