Looks like a little bit of Bartlett ridging North just enough to give a touch of frost I'm afraid - absolute tat.

No Atlantic blocking but doesn't one of those show an Easterly (Scandi block) by 29th and another a UK high?

Not familiar with those charts or up on my Icelandic

Just seen the latest forcast and all they're saying is watch this space for Tuesday - Thursday. Be prepared for a lot of slight changes on the Models. Yesterday the weather system on Wednesday/Thursday went through the south now it's more towards Scotland. It wouldn't surprise me if it ended up going through the middle. A lot can change in 24hours.

It’s all about 168-192 tomorrow...??

Have you been on the sherry again! :D

As backtracks go the last 36 hours would give a trigger shortwave Scandi high trauma a run for its money.

Once again the UK feeding off scraps at the buffet table.

It really does suck to be a coldie in the UK.

Okay I will take your word for it as I am not sure how to interpret them  :D

Would of thought that colder cluster on the graph though can't be Westerly based as they have London sub zero at night and 2 or 3C during the day.

Just hang fire to tomorrow eve ....

Steve, you were predicting a very cold flow over the south this weekend (I was dubious with the warm continent). You were quite certain of a col and temperatures close to zero by day. As you know, it’s been far from that cold.....

Looking great for my area (West-Central Scotland) for snow in the next 72-96 hours! Models are giving some great snow potential from that midweek storm (Fionn soon maybe?), along with all those bloody showers from tomorrow evening onwards! 

Shame that this week's potential is being dampened by the IMBYness in here, just because it's not what a lot of us want. I was bloody fuming when those sliders were dumping FEET of snow in the Midlands, now it's our turn! :D

I thought that one with the uk high would still give frosts under clear skies or the slack one that's not far off a continental drift without actually being one but I stand corrected because I hate those charts and maybe its me who cant read them!

Yep - not as cold as predicted — but the 500Mb pattern was pretty good match for Europe-

The 2 late Minor models continue to push back south of the storm

Ian F has just tweeted that Thursday storm could be 250 miles further North or South than currently shown, still lots of uncertainty from METO.

Ensembles say it all really. Cold for the north till end of the week and then huge uncertainty after that. The jetstream is meandering alot so I dont buy zonal mild trash.

There's a few stonkers in there actually - more than I thought looking at the mean.

Well said! 

As you said lots of potential for snow to fall here across Scotland over the coming week. If the models are correct then some areas could see some serious amounts of snow.

Thundersnow? Yes please! :yahoo:

and the good thing about it is, any one of those "stonkers" is a feasible outcome. :good:

Nothing as good as the one already pointed out but a few -7c or below and attempts at splitting PV - too much of a mess and that usually isn't a good sign.
