Pattern Dazzling December

Sending it yalls way! Finally gonna feel like Christmas!

Tar Heel inspired me to look at my TWC forecast for Roanoke (which is just the GFS forecast). Looks great haha

To top off the weenieness, the GEFS at the end of the run had another jet extension with another bout of Aleutian low ? remember how persistent it was last January ?

 

[Myfrotho704_]

this is one of the best 10 day modeled patterns I’ve ever seen

Not much change with the 18z EPS to me, basically the same

 

[griteater]

Look Mama, we made it

 

[griteater]

18z GEFS Mean AO gets down to -4.6

 

[NCSNOW]

The GEFS literally has it all. -EPO/-NAO/-AO/+PNA, a strong subtropical jet, nice 50-50 low, with a wave hanging back over the SW US

The Holy Grail Pattern

We could literally have a board wide from Texas to Virginia and up toward Iowa snowstorm and or multiple snows within a week in this set up. It really doesn't get any better. Not saying we can't find a way to screw it up but man I can't recall a more promising month ahead.

I mean could it get even better??

Yeah, center the lowest heights in SE Canada. Then we can get rid of the Great Lakes Low on some of the models

Well considering the last decade it's about as good as it gets or as good as we've seen imo.

Great Lakes' lows, or troughs centered over the great lakes, typically regress eastward with time. If this look verifies, our highest chances of a Miller-A storm would actually be around New Year as opposed to Christmas week.

If I'm keeping it 100 (lol), it was nice to see the GEFS trend a little east with the TPV that drops down above the Great Lakes and into SE Canada, but remember, the GEFS is the farthest east with this feature as was discussed. The CMCE and EPS were farther west with it. Both of those eventually push it east, but we would likely get into wintry threats quicker with the GEFS solution as it offers more ability to keep storms from climbing north. If you are in western areas of the forum, it's less of an issue for you.

Anyway, let's see where we go this evening. Here's a comparison of the big 3 ensembles with the placement of that TPV as it drops down - 18z GEFS / 12z CMCE / 12z EPS

Nice look on the 18z EPS next weekend.

ICON 00z taking a step in a better direction out west getting rid of the deeper low pressure off the coast

Mean trough axis has shifted dramatically further east on the ICON over the past few runs.
