The other thing that I think we're fighting a bit (in addition to the AK vortex) is the Atlantic block really for most of the first week of January is too far east IMO. I'd like to get the core of the block west of Greenland in Baffin bay. It kind of gets there at the very end of the GEFS run, but it's late to the party. Earlier it looked it was going to set up nicely there the first week, but it's backed off of it I think. With the pacific and not ideal Atlantic block, not excited for the first half of January, but we'll see I guess. At least we're not last year.

Don’t read too much into the exact placement of the block on a long range ensemble mean, it’s almost always going to be dampened & equatorward vs reality (which suggests it could be too far SE). Odds are, if it’s very amped as the ensemble already suggests, it will retrograde west in time as it advects itself against the mean westerly flow.

For areas west of the apps our best chance is the New Year’s Eve system. We want the low further south . Right now it favors western Tennessee.

The weekend system. Would most likely be a late bloomer and favors the Carolinas

Further South meaning like the gfs

If nothing else this is impressive to look at. Euro shows a split at 10mb...I didn't realize a split favored cold in Eurasia and not necessarily in the conus.

There could be some wave 2 at the end, but this is mostly a displacement/k=1 event. Stratosphere-induced temperature anomalies are stronger and more significant overall in Eurasia than the CONUS. Only the SE & eastern US have significant temperature anomalies from sudden warmings in the lower 48 and those anomalies are even more significant if you sort for SSWEs during El Ninos which are more frequently displacement type (like this one will be).

Just an fyi for anyone that didn't know you can get free euro precip maps at pivotal weather. No eps stuff though

How do I get to precip maps? All I could find was like 850 maps and such?

Do you know why those areas are favored? At first glance one would think any geographic area would be equally favored for a warming event happening at the pole.
 
Do I have to sign in? I think all I saw was mslp maps. I was in a hurry and am at work,

You have to go to the ecmwf hi-res model to see the surface
