December 2021

[Iceresistance]

The 12z GEFS (November 21st, 2021) is showing this for December, it's been showing the primed cold air for a while. (not in detail until now)

[Stratton20]

Iceresistance yes Ive seen this, I definitely think we will get a few cold snaps in december, but the cold air definitely will start to build up in canada over the next several weeks, just a matter of wheb it comes down and where it goes

[Iceresistance]

The GFS model is showing consistency of at least 1-2 major Winter Storms across the CONUS in Early December

[Stratton20]

Iceresistance that is pretty far out, still their are signs as we approach the first week of December of potentially arctic air spilling into the united states

Any heading to SETX?

[Stratton20]

Sambucol na, its so far out

Don't know, it's too far out to be 100% sure.

EDIT: The 2 storms are no longer there, but there is consistency for a cold wave in the same time period

The 12z GFS must be drunk. It’s showing a 1067mb high in western Canada.

That’s major. Correct?

never gonna hold up...never does

[Stratton20]

Thats far out, but something to watch, a 1067 mb high is no joke

1047mb highs have a hard time verifying much less 1067. That would be historic. I miss srain. He’d always write up these paragraphs for us on here if he thought something was coming. Since he moved, he rarely posts. At least half of what I know about the weather came from him.

Seasonal on average for the next 6-10 days. NOAA is betting on warmer in mid-December but I'm going to roll the dice on a brief cold snap.

Which model has that?

EDIT: 12z GFS

[Stratton20]

I dont think december will be warmer than nornal, especially with the cold air starting to build in Alaska, keeping my fingers crossed that NOAA is wrong here And Iceresistance the 12z GFS showed that high

The 18z GFS has a 1053 MB High in Southern Canada & in Montana

[Stratton20]

Iceresistance yup saw that, their definitely is a signal that changes will be on the way as we head toward the first week of december , a cold snap would be welcomed

[Iceresistance]

18z GFS is getting me strongly concerned for Early December

Thats far too out on the model to be worried about right now IMO

But the GFS has consistency on the potential December Cold Wave, this storm is only proving it, it needs to be watched very closely . . .
