Drier Air Arrives Tonight

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

THIS MORNING: As projected, a deepening surface low is near Columbus, Mississippi early this morning. This low is headed northeast, in the direction of East Tennessee, and is pulling a warmer airmass northward through Alabama. A band of showers and storms will move through during the morning hours, but at this point there is no surface based instability, and we still don’t expect any severe weather for the next few hours, However, later today in the warm sector, there could be a few storms that try and rotate due to the high levels of low level storm relative helicity in place. The best chance of severe weather later today will be south of a line from Roanoke to to Montgomery to Andalusia, where SPC has a slight risk of severe weather defined. We will keep an eye on Clay, Talladega, Calhoun, Cleburne, and Randolph Counties later this morning, where there might be a little instability involved.

Additional rain amounts of 1/2 to 1 inch are likely today, and many places around here will wind up with a storm total of 2 to 3 inches. Very beneficial.

HANG ON TO YOUR HAT: The pressure gradient will tighten up in response to the deepening low, and winds could gust as high as 30 mph at times. The NWS has issued a wind advisory.

TONIGHT/TOMORROW: Colder and drier air arrives tonight as the sky becomes clear. We start the day in the mid 30s tomorrow, followed by a sunny sky and a high in the low 60s.

THURSDAY/FRIDAY: A secondary push of cooler arrives Thursday, but there is very little moisture and we don’t expect any rain. We will call it partly sunny with a high in the upper 50s. Friday will be cool and dry; the colder spots could see a freeze early Friday, with most spots in the mid 30s. The high Friday will be at or just over 60 with a bright, sunny sky. The weather will be perfect for the Alabama/Georgia State game at Bryant Denny Stadium Thursday night, with temperatures falling into the 40s during the game with a clear sky.

OUR WEEKEND: Very, very nice. Sunny pleasant days, clear chilly nights. Highs in the 60s, lows in the 39 to 44 degree range. No chance of rain.

THANKSGIVING WEEK: Watch the Weather Xtreme video for a day by day look at next week. The latest few runs of the GFS have been trending slower with the mid-week rain. We might see a few showers Tuesday and Wednesday with mild temperatures, but the 00Z run of the GFS brings in the main band of showers and thunderstorms on Thanksgiving Day, with potential for strong storms. Then, Black Friday (and Iron Bowl Friday) looks dry but sharply colder. This, of course, is still out there in voodoo land, and this could (and probably will) change.

The NAO still shows a strong negative spike as we begin December… the gates to the Yukon could very well open up if this is true. See the Weather Xtreme video for the charts.
