Latest Model Runs Show Arctic Blast…

Quote:

The Arctic air is on the map Tuesday afternoon, with a huge pocket of sub-zero air across Central and Northern Canada. The computer models have been very consistent over the past few days in taking this air westward, then southward into next week. A monster area of high pressure is prognosticated to move down the spine of the Rockies, setting up a persistent northerly flow for areas east of there for much of next week. The northerly winds will drive our highs down into the 40s, and perhaps even the 30s, by the end of the week. That will set the stage for lows in the 20s, if not colder. What continues to be interesting, as Heath mentioned in the previous post, is the possibility of some wintry precip by the end of next week. If a low forms in the Gulf and throws moisture back into the cold air, we could see some snow - for the third winter in a row! Here is the Tuesday morning run of the long-range GFS model, valid next Thursday evening, January 13, at 6 PM.



If this were to verify, there would be a swath of snow from Texas to the Florida Panhandle. Odds are the actual scenario will be different than this. However, the probability of a significant Arctic outbreak looks higher by the day and with the cold air in place, any sort of precipitation that manages to form could be of the frozen variety. We’ll certainly keep watching the latest model runs and keep you posted on the potential.

Joe,
I've just finished a Christmas with 9"-10" of snow up here in the Ga. mountains,and am going to be in East Texas at that time. Are you telling me I might have it AGAIN? It seems to be following me!!!

Yes you are and my kids and I want to thank you. Looks like we might get a double shot of snow - 1st) Jan 13th and 2nd) Jan 17th.

Bring it baby.

Oh awesome, I was looking at the GFS lately and it sure does look like this could verify... but this being over a week out, a lot of things can still happen! But I'm feeling pretty good about this one

Quote:It remains to be see how cold it gets here in Alabama, but it is safe to say we will be very cold in the January 12-16 time frame, with potential for single digits lows along the way with sub-freezing highs. It also remains to be seen if we have an overrunning event that would bring the potential for an ice storm here. Watch the Weather Xtreme video, and you will see the GFS hints at snow for Houston, New Orleans, Mobile, and Gulf Shores around January 13, with nothing up this way. Again, this is all voodoo.

[FrenchQuarterGuy]

Well, the cold is for sure going to be here... it's just a matter of moisture. Still praying for a flake or two

70's one week.. 30's the next, with a chance of snow.. Gotta love living in the South.
