December 2021

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

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

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 . . .

I feel like when you look at something that far out, it’s always better to go by the ensembles. I do agree that it’s something to watch though.

[Stratton20]

Iceresistance Yes I do agree it is something to be watched, but it is 12-13 days out, so expect changes

Light freeze Dec 8/9 near the Houston area, but that's no surprise.

[Stratton20]

by days 11-13 the 12z GFS is showing the potential for a huge arctic outbreak in early december, still far out but their definitely is a growing signal for this

by days 11-13 the 12z GFS is showing the potential for a huge arctic outbreak in early december, still far out but their definitely is a growing signal for this

Also 2 Major Central & Southern Plains Snowstorms, the entire State of Texas will go under a deep freeze if the 12z GFS verified.

[Stratton20]

Iceresistance definitely something to keep a close eye on as we move closer to december

Iceresistance definitely something to keep a close eye on as we move closer to december

Forgot to mention that there are 2 POWERFUL High Pressure areas in December as well, 1059 MB in Wyoming & 1056 MB in Colorado

[Stratton20]

That would definitely mean some seriously cold air for december, model support is starting to grow on to this arctic blast, will see as we get closer to that timeframe

Thinking ahead. If that does verify, how cold? Wondering if we will have rolling blackouts.

[Stratton20]

Sambucol it would be very cold but nothing like last february though, thats if this verified, still too far out but at least their is a signal
