Right enough of this shameless ramping! :D

I’d advise people remain cautious and not start picking out hats for the snowman till the track of the slider and depth of cold gets within T48 hrs.

The same thing happened with the GFS super blizzard which met a tragic end.

I know it’s hard and it’s exciting because snow has been so rare in recent winters but I have several counselors off on holiday at the moment and the NW helpline simply won’t cope if it goes pear shaped ! :cold-emoji:

Ha ha everybody needs to take it run by run,step by step,day by day let's just enjoy the ride.

You know what - I havent seen 1 hopecast on here. People have put all their points of view across in a pretty good mannor- infact its been pretty good debate. The only post that sticks out a mile

Still coming slowly off a cautious fence Long term total global atmospheric angular momentum trends can tell you a lot about pattern changes due to the effects the rises and falls in global wind-

I hate bringing a word of caution re. FI on the GFS, but ...

I'd like to see a lot more agreement for the cold. However, ECM is great so here's hoping. Meanwhile, a tasty cold weekend brewing here :)

Thanks for this - a rare sight indeed, when did we last see a classic 5 wave pattern - I can't remember, long time that cold in east USA/E canada has also occured with cold here.

@rossby waves!..

Tut-tar mr jet!....

Anyway much lies ahead' and like a broken record!..

Pointless atm of exacting on the first slider incoming [email protected]/placement/overhead bearings.

This is a wide open as they come(and usualy are)!.

1-things for almost certain some will be making the news -weekend-early next week!??..

Fridays all round suites are the defining line for me...

Meantime try to gage' some definition on the incoming wintry weather....

And chill a tad!!?

ECM eps are an absolute stonker and an upgrade on the 0z upto around D10-12, after that there is still a euro trough but it gets pushed much further south and east and is weaker than it was a few runs ago but there is signs of a height rise between Greenland and Scandi which ties in with a growing signal in the GEFS extended of a 'Murr sausage'

is this 4 inches falling or 4 inches lying as they are completely different not every flake lies obviously please  people dont get carried away with computer generated maps of snow cover many people will disiponted when they turn out wrong :cold:

No its lying, although looking at snowkings graphic, they could have been lying in another sense!!!  They do look well overdone those charts.

Overdone?

Certainly not a lot of moisture is associated with these slider lows typically somewhere gets a good dumping.

Yep, it’s not your typical slider coming up against a block that sucks the moisture out of the system, somewhere is going to get a serious dumping!!! Still to be resolved where, Oxfordshire somewhere is my bet.

I'm talking the ones on weather.us, they have been showing ridiculous snowfall totals over the last 7 or 8 runs.

Bit further east in biggin Hill will do nicely

mate

18z should help with the correction.

if it’s south again that’s a small trend

if it’s north I give up till th 0z

OH NO on the 18z  at  6h the Greenland high bone has connected to the Scottish low bone which can only mean the sliding snow fest will track into the Bay of Biscay which will mean the jet fires up and the blo torch westerlys pick up and we all BBQ for xmas ..........Does it not?

well  the event Friday has a few hot spots under snow for hours on end.  even if it were 1 flake an hour  people would still have a covering.   Now for the slider

well i hope its on the conservative side of things and its even HIGHER more southern and flatter areas deserve something better after 3 years of dross after last weeks 5 inches lying for 5 days here a further 10 would cheer me up nicely it can lay here for weeks on end the best of luck

Would be good to see the Euro trough extend further east if we were to get an easterly further down the line, as over the next few days there is a lot of WAA pumping up across Wern Russia and eastern Europe the source region for an easterly. It's all very good having an easterly, but you need the source to be cold. Strong southerly jet tracking into western Europe to the south of the UK next week may help extend the  Euro trough south and east though. Anyone notice nasty deepening low moving across France Monday on EC?

Anyway, that's too far off in the future, snow shower watching Friday and Saturday, slider low with snow threat watching on Sunday ... more than enough to concentrate on for now.
