Cold December Days

The Tuesday morning map discussion video is on the server:

On mornings like this when I worked on Red Mountain many years ago I would say it is so cold I saw Vulcan with his hands in his pockets. We are way down in the 20s, and we will run the complete list of lows on here later this morning. Looks like most communities will have lows between 20 and 25 degrees.

Dry but cold weather continues through tomorrow. Another significant freeze is ahead tonight. Once again, we reject the MOS guidance numbers. They are too warm.

THURSDAY: Once again, nothing on the big map board this morning to make us change our minds in the event. Mostly a cold, rainy day for us. But there are some issues:

EARLY MORNING: At the onset of the precipitation, tempertaures could be near freezing over northwest Alabama and parts of the Tennessee Valley. Even if temperatures are in the mid 30s, evaporative cooling could bring temps down to 31 or 32. This could mean some bridge icing early Thursday morning thanks to a wintry mix. The best chance of this is along and north of a line from Hamilton to Cullman to Collinsville. I guess we can't rule out a few icy spots as far south as I-20, but that looks pretty unlikely at this point.

A cold rain should fall during the day Thursday as temperatures warm into the upper 30s.

THURSDAY NIGHT: As the surface low moves up the Atlantic coast, cold air will deepen and often there is a brief change to light snow before the storm winds down. The best chance of this seems to be over northeast Alabama; mainly across high terrain (above 1,000 feet). I would not be surprised if a dusting of snow is found early Friday up on Lookout Mountain around Mentone and Desoto State Park. And, I guess flurries could be seen as far south as Birmingham, but once again that looks unlikely at this point.

Other regional notes about this storm system:

MEMPHIS: NWS in Memphis thinks the city could see 1 to 3 inches of snow from this storm. Best chance of accumulating snow will generally be along north of I-40... with a wintry mix to the south down into far northern Mississippi and northern Alabama (as discussed above).

CAROLINAS: The ole CAD effect (cold air damming), or the WEDGE, could set up some ice with this storm from northeast Georgia up through parts of the Carolinas.

DALLAS: A winter storm watch remains in effect. Some ice and snow is possible for the metroplex tomorrow and tomorrow night, and they will probably hold in the 20s all day tomorrow with Arctic air invading from the north.

FRIDAY/THE WEEKEND: Friday should feature gradual clearing, and the weekend will be dry. Hey, we might even reach the low 50s... like a heat wave!

The GFS is now holding back the next storm system until Monday night and Tuesday of next week... will wait until the 12Z run before we change our forecast.

LONG RANGE: Looks cold. We, of course, will have periods of warming, but the overall trend looks cold. With those -50s showing up in Alaska and western Canada, you have to think it might be pretty cold down here as we approach Christmas....

COLD WATCH: A quick peek at current Alaska observations shows -42 at Deadhorse. Ouch.

YAHOOOO: Our streaming agreement with AL.COM is on Yahoo:

James,
Is the streaming video in Real Audio format or Windows Media? It would be nice to have a choice. Where I work, they block Real Audio for some reason... Thanks for the hard work!

Now, GO WORK ON THAT SNOW THING!! Just Kidding!!

Mike

I watched the live video and it worked great during severe weather when I did not have a TV.

I have a question....
This morning there was an accident on I-65 South at Hwy 31 supposedly due to icing of the road. They had to bring out a sand truck. If that was the case today, do you think we'll have more problems than suspected Thursday morning down this way? Like icing of bridges, etc.
Thanks for all you do.

No... the reason there was patchy ice this morning is because the leftover moisture was still on the roads when temperatures fell below freezing. Unless the temperatures are below freezing when the rain starts Thursday(not looking likely), there won't be problem.

Thanks for answering me. Most of the time when I post no one ever responds. I don't have questions a lot and I am FAR FROM a meteorologist, but I like reading what people think.
