The GFS is coming around to a very interesting solution for our weather in the Sunday-Tuesday time frame. But first...
Another freeze is likely tonight. Dewpoints are still in the teens; I think most folks will see 20s by daybreak tomorrow. We are watching a large cloud mass to the west; if those clouds move in here later tonight they could hold temperatures up, especially over West Alabama.
Those clouds will make for a partly sunny day tomorrow... the wave responsible for the echoes over Texas and Louisiana will fizzle and we still expect a dry day tomorrow, and a dry day on Saturday.
COMPLEX SYSTEM: The 12Z GFS is basically advertising a two part storm system now. The first part comes here with a batch of rain and storms late Satudday night through Sunday morning. Upper support now looks limited, and severe weather is not likely. Rainfall amounts of 1/2 to one inch are a good bet with the first period of rain.
PART TWO: Another round of rain and storms is likely late Sunday night into Monday with a stronger upper air wave and a surface cold front. The dynamics will be strong, but once again the thermodynamics are somewhat marginal for severe weather. This should bring another 1/2 inch of rain for most communities.
A COLD CHANGE: There is some Arctic air behind Monday's front. Much colder air will roll in here Monday night into Tuesday. Parts of North Alabama might hold in the 30s all day Tuesday; for now we will forecast highs in the mid 40s here. Wrap around moisture could bring a few snow flurries to North Alabama late Monday night into Tuesday morning; the best chance would be over the northeast part of the state.
AN EVEN COLDER CHANGE: Once again, the GFS sure looks cold as we get into February. For the snow fans, check out the video and see the model output at 240 hours; that shows a nice snow storm for Alabama. But that is all voo-doo at this point; it is just a possibility in this kind of pattern.
A monster western Canada ridge builds in the February 8-11 time frame and will pull some really cold down down into the "lower 48". That is why we are paying so much attention to the temperatures now in Alaska and the western part of Canada.
Thanks to the kids at Bragg Middle School in Gardendale today... they were a great audience. They will be on the KIDCAM on ABC 33/40 News at 5:00. I will be live down at the BJCC at the circus... I will fit in nicely with the clowns.
The next map discussion video will be up by 7:00 a.m. tomorrow!
