The Pattern beyond Jan 12

With so much focus on the impending 1/12 event, we really do not have a thread to discuss anything beyond that. Right now it appears that there will some sharp thermal gradients with very cold air in Canada at times trying to spill over NE. The heart of the cold looks to be over the Canadian Prairies and the upper plains of the US with a mean trough position over the central US...this will put us on the eastern portion of the thermal boundaries...and could offer up several chances at SW flow events or gradient type storms.

Euro shows a weak overrunning storm around D6 with a more significant storm around D7-8...that one as modeled has snow changing to sleet/ice written all over it. Its far enough out that all options remain on the table. It looks like a cold storm though with high pressure N of the lakes extending over into Quebec...even if the mid-levels try to warm.

Euro then shows another possibility after D10...it definitely looks like quite an active pattern but certainly a lot more opportunity to taint ptype. It could end up being a very fun pattern though if we can stay on the colder side of most of these gradients...ala 1994.

Can you comment on what you think the conditions will be for the Pats game on Sunday afternnon?

As far as the GFS is concerned it will be incredibly cold and REALLY REALLY sunny out west. I think the 0z gfs had the biggest high pressure i've ever seen settled over the western US. Verbatim there wouldn't be a cloud in the sky from Cali to the missisippi for like two or three days. I mean it could happen but IDK...

moderation seems likely.

Possibly entering a pattern of repeating 8 inchers on a 3-4 days cycle... "maybe"...

PNA on the rise with a -AO offers deep scenarios in the east as well.

CMC and NOGAPS are the junket models but they are flagging 1-3" this weekend, then the NOGAPS actually has the Euro coastal storm next week interestingly enough.

Pattern is not going to be inactive post this event.

Welcome to 1993-94....among my all time favs...

This looks more and more like a gradient pattern for a time. Those are my favorites because our latitude really helps. 1993-94. Tonight's GFS advertises this. And the timing is such that my 1/18 flight to TPA would be delayed or canceled. Which means I may not have to go because if it's an event of size (the snow/ice), 24 hour cancellation means its not worth attending this meeting...of which I'm a principal...oy vey but snow first!

Didn't think the GFS looked all that impressive with the clipper system but from Steve it sounds like the NAM is a bit beefier.

As far as next week goes this certainly looks interesting right now, this almost screams overrunning potential. I know right now through 138 HR the GFS has some strong WAA occurring in the lower-levels but honestly I wouldn't bit at that just yet, still have that cold high just to our north and with the decent snowpack that has been built it totally wouldn't surprise me if as we drew much closer we start to see a more colder solution.

This screams ice storm with a 1030mb high over Quebec, under which sit -30C 2m temps on the 120hr GFS, and a low cutting to our west with a trough anchored over the OH Valley. Would be an interesting set-up for overrunning snows followed by ice, perhaps eventually changing to rain in SNE.
