Pattern December to Remember

Everyone’s favorite. Cold and dry.

That W Pac typhoon supercharges the -EPO on this GFS run

Christmas morning I'd take it and run

 

[Wild Weather Monger]

Based off what ? Imo I still like After Christmas/early jan the GFS often is to quick

We're getting quite a few operational runs off and on out in this timeframe threatening an artic outbreak along with various storm signals that week. Just the latest 12zGFS with cold air in place with a reinforcing shot following along with a robust low pressure near S. Florida is intriguing, to say the least.

Cutoff out west progresses east and starts to muck things up starting Christmas day

Need that cutoff close to the GOA we always make these cutoffs/-EPOs work in spring seemingly

East Coast Ridge Flex in 3...2....1...

December 25-January 1st that will be pattern change week or at least a period where we start shying away from monster SER vs more cold attacks

If it were able to retrograde under the ridge trying to nose into AK to its north the gfs would have printed out silly cold numbers. Nice trend to see but let's see if there's any legitimacy in the look within the gefs or the other models today

Still so far away at this point almost everything at that range could just be noice .. updated MJO forecasts may be helpful in trying to grind down generally where we’re headed in that period

Enjoy the cold while you have it! Don’t be looking at how we screw it up in 19 days! ?and I’m trying to look at the brighter side of things these days! After 35 and rain today and tonight, I get to finish with a deform band and 35mph winds! ?

East Coast Ridge Flex in 3...2....1...

Seems like we will be fighting that fight for a while

 

[Tarheel1]

I get to 29 degrees on the 20th, and basically don’t get much above 20 degrees through the end of that run on the GFS!

 

[Webberweather53]

GEFS also trending to a stronger -EPO in the extended. The W Pac typhoon superposed onto the MJO amps the N Pac wave pattern even more sending a stronger ridge into the Beaufort Sea & Alaska later in week 2.

More excellent work by BAMWX. Their forecast is laid out clear and concise.

Myself, I would not expect much of a chance of snow except in the mountains as the storm track could favor inland paths

Love 2 c it

Starting to look like a classic CAD pattern.

Gefs with actual BN temps in the SE at 300hr

Nice pattern to pump out Miller Bs
