Pattern Dazzling December
- Thread starter Rain Cold
- Start date
Our “cool” shot next week has been trending much colder because the injection of energy rounding the AK/BC ridge 
This is getting hard to ignore now. I imagine a lot of Mets will begin to discuss this potential over the next 1-3 days. Incredible pattern coming up right before Christmas
I think we’re starting to cook here… 
Dang 1076mb high coming out of BC on the Canadian
How about a little baja vort Christmas miracle..

That first little storm on the GFS run came from a wave pinwheeling down from the northern stream…but yeah, the thought occurred to me that we have no idea where these storms are going to come from out at range, but if we can get this pattern to set in, it’s going to become harder to miss out
No pair of pants are safe this week. We’re going to see some wild runs.
Very well put. The occasions of the southeast getting a decent storm without snowpack in place across the north are few and far between. The only times that come to mind are the Christmas Ice Storm in 1998 and 1/2-3/2002

Really hope the 12z Euro and EPS will show some support from what we just saw from the GFS in regards to next weekend. That’s a nice look for us to the west. All of this mild weather we’ve had will be 100% worth it if this pattern we are starting to see will unfold. Some very exciting times ahead and some late nights coming. No better time of year for it than the week before and of Christmas. Really hope we can get that board wide snow storm that we’ve all been waiting for what seems forever.
The gefs is pretty mid with the GFS storm barely any support
Theoretically this could end up being our legit table setter for the energy that comes after this storm. Very marginal cold air to work with here but this type of storm would surely bring the cold air south enough to where we want it for whatever happens 20-25th .. exciting model watching times ahead. Expect some fun runs over the next several days.
Such a weenie pattern on the 12z GEFS 
One note of caution for those of us east of the Appellations, this pattern as modeled favors areas to the west where the best cold looks to set up. Texas to Alabama looks like the place to be for the next couple of weeks.
Energy phasing in the pacific, ridge sliding east and +PNA/-EPO is the result, with the west based -NAO trending stronger again as well
Trends are incredible right now
Trends are incredible right now
Of note, the mean trough axis has shifted east on the GEFS. Nice!
Not necessarily. I agree that the biggest temperature anamolies will be west of the Apps, but this is an overall pattern that does promote better opportunities of strong CAD east of the Apps. Also we’re going into an MJO phase that supports a more muted SER.
Edit: I should have said that yes those Texas to Alabama are in very good as they have more ways to score, the overall pattern is such that could support a long tracking board wide storm
