T144 this morning, all of the big 3 showing a snow event that is likely to become more pronounced over the following days. Hard to say which chart is the coldest. What a turnaround!

Even better runs this morning, with the colder air further West..

Quite right PM.

A cold easterly is imo the king of winter weather patterns (If it's cold and snow you're after like myself).

Your point of the cold beginning to back further west as shown on the output is a classic sign of westward correction. Let's hope it continues thus leaving us more room for error.

Awaiting first post that says but it won't snow IMBY etc!! I think many will be surprised to see such consistency from the overnight output and how quick the change to cold looking output it is. Fantastic. Now awaits SW drama!!

What spanners could be thrown in the works then?

It looks a fairly uncomplicated solution to cold that all the major models now show. No counting this one down from 300+.

The fact it is evolving so fast fills me with even more confidence......it just seems the most sensible and likely outcome!

Its cross model support from the ooz, s. With what looks a certainty transition to cold. Perhaps some might not question any possible upset to the evolution, but consider firmer upgrades even still. After all all the synoptic s are there.

Huge movement from all models really to cold solutions, and it's not far away (the development of the Scandi high) so a couple more runs and we should be home and dry

I can't believe the turnaround this morningI think that a lot of posters would do well to save this weeks charts just so they can remember how quick things can change.The experienced posters on this site are fantastic and have been saying for months that a change will happen anytime and doesn't necessarily have to be shown in deep fi.Some members writing off winter can now see our weather on this island is prob the most complex in the world.We are so privileged to have some very knowledgeable posters on this site and is what makes it such a great season.It's coming at last.

Couldn't agree more. As I don't understand all the models the experts are fantastic. Thank you for your your coverage of this up coming cold spell!

Well well well this morning feels like we have rolled double 6, landed a royal flush and spun green 0 on roulette all at once,

No fancy analysis required no detailed confidence posts just happy that all the main 3 are identical st 72,96,120 and 144 with wiggle room for upgrades and potential for snow as early as late sunday....

ECM 168 has widespread -10 air & -12 just coming across the north sea

The same north sea thats warmer than usual.......

Have a good day

S

indeed steve I chocked on my coffee I nearly got out a bottle of fine wine.

cross model confidence across the board and I must say the gem and jma performed amazing in this run up.

 

incredible and how quickly has all this evolved in one night the whole lot went all in the same direction and seeing the gfs lastnight back tracking was a good step.

but to wake up this morning and see this wow.

 

oh please don't let this be a last minute fail incredible absolutely stunning streamers anyone.

Looks great for cold next week, looking at the charts has this got the scope to be prolonged cold????

Looks like it's not one that will last too long, plenty of time to change though...short cold is good after the start we've had...

Oh yes...

Get the cold in place and worry about the snow later..

Well thats what we were all hoping to see this morning and just what you want to

see at the t144-168 time frame rather than at t240 and likely to implode.

Will be very interesting reading the turn around on the Met update later.

Excellent stuff.

If it happens, still FI remember but well done to carinthian, who seemed to predict this when no sign of it on models,

Correct, I wonder where he gets his data from in Austria ?
