The morning map discussion video is FINALLY on the server:

Had some wi-fi issues that have finally been resolved.
Cold is the word this morning; everyone around here is below freezing. Some spots are down in the mid 20s; I see where Anniston reports 26 degrees. We should note these numbers are well below the GFS MOS values that were shown yesterday. As J.B. writes below, there is some patchy dense fog out there, and of course, any leftover wet spots are now icy spots. Be careful out there.
We enjoy ample sunshine today, and a decent chance we reach the low 50s this afternoon.
BOB: Our weekend storm will zip through here tomorrow night, and the rain will come while many of you are asleep. The NAM is a little wetter, and GFS a little drier. Both models show the deeper moisture over south Alabama. Critical thickness values remain to the north of here, so the chance of any wintry precipitation around here looks very small. Just a light, cold rain Saturday night. Best chance of rain now seems to come from about 4:00 p.m. tomorrow through 4:00 a.m. Sunday. Any ice pellets or snow flakes would be north of U.S. 278, and up there the moisture is so limited there might be little precipitation at all.
NAM extraction shows only 0.12" here from Bob. Nothing to get excited about.
The sun should return on Sunday and Monday with chilly temperatures.
HOPE: Our final storm of this series comes in here in the Wednesday-Thursday time frame. The big question is this: to phase, or not to phase. The GFS and the European say no phasing... they keep the southern short wave apart from the northern branch. This will prevent any really cold air from getting involved in the storm, and also prevent it from becoming a super-duper storm of major strength.
I think the best course of action is to go with the "no phased" look for now. If that is correct, then Hope will be very similar to Bob (the weekend storm coming in) in terms of the imact on Alabama.
The 00Z GFS looks good to us; it shows a surface low in the Gulf of Mexico with precipitation extending up over the northern two-thirds of Alabama late Wednesday night into Thursday. The 0 degree (C) line at 5000 feet is over northwest Alabama, so for now it looks like a mostly rain event.
But again, like I have written here dozens of times, I like to take these systems one at a time. So, once Bob gets out of here we can have a really good look at Hope.
CHRISTMAS: The GFS continues the idea of a storm system to the west of Alabama on Christmas day, with a rain mass to the west over Louisiana, Arkansas, and Mississippi. Temperatures should warm to "normal" levels for this time of the year (50s and 30s).
The 06Z GFS goes nuts with the system develops a deep upper low over Alabama and Georgia the day after Christmas with very low thickness values. I don't trust any specific solution right now as the model is struggling with the pattern.
Headed over to Anniston today for the annual "Bake A Christmas" day at WTDR-FM, Thunder 92.7. Those guys have been doing this for years; they auction baked goods and a variety of other cool prizes to raise money to provide Christmas toys for families in need in east Alabama. If you live in East Alabama be sure and listen, and give us a call!
The afternoon map discussion video will be ready by 3:30 this afternoon...
