A good GFS run with a good dollop of snow away from the SE where the low closes off however there probably around 200 miles of variability for that low - in terms of location so no real concrete location yet-

Post that Easterly building...

The point where it makes sense to swap posting NW view charts in favour to the closer Euro view - this is a great run, and well within the possible range of the extended, all in, super-ensemble.

Just wished it would be better uppers and hold its position and not sink.

Uppers less important in an easterly and with embedded surface cold in the preceding days.

Those asking about a scandi ridge as opposed to the predicted greeny ....... the recent trend to scandi ridge wasn’t an extended ens idea. It’s grown recently on the back of the east Atlantic height rise pushing northeast (and possibly behaviour of the arctic high which is tough to predict) 

my thoughts are that a height rise seems to be an extension of the wedges that have been modelled but with the downwelling now showing in the trop,output, these are trending to Upper ridges ...... the Canadian vortex is too close to greeny to allow one to appear within the next ten days around Greenland  ..... hence more towards scandi. As the Canadian vortex sinks further into n America, so any ridge can retrogress towards Iceland and then Greenland  

Basically if you were to look textbook coldspell for the UK up, that’s it right there!

scandi—> Griceland—> Greeny :spiteful:

No you need steep lapse rates not just from surface to 850 but further up than that as well in order to create convection - you don't need  -15c like march but -10 would be needed together with 520-530 (ish 500mb heights, preferably -12c
