An all new edition of the ABC 33/40 Weather Xtreme video is available in the player below, and on iTunes…
With a clear sky and light wind, temperatures will drop pretty quickly this evening, and most spots will wind up in the mid 30s early tomorrow, with a freeze for the colder valleys. Tomorrow will be a nice day with ample sunshine an afternoon high in the mid 60s.
A dry front rolls through here tomorrow night with some clouds, but no rain. Then, a fresh supply of cooler air arrives on Thursday with daytime temperatures about 10 degrees cooler. Most everyone around here will be close to freezing by Friday morning.
THE WEEKEND: Saturday still looks dry and pleasant with a high in the 60s. To the west, a major storm system will form just east of the Rockies, with a deep surface low over East Colorado Saturday. This low is forecast to move from that spot to near Chicago on Sunday, and will drag a strong surface cold front in our direction. While a few showers are possible during the day Sunday, the GFS continues to hint that the primary risk of showers and storms ahead of the front will come Sunday night. The 12Z run of the GFS has come in with a stronger upper trough and surface low, hinting that strong storms could become an issue around here Sunday night. Instability values still look marginal for severe weather, but models might be underestimating the moisture return. Something to keep an eye on for the rest of the week.
Still looks like a system with one-half to one inch of rain for Alabama… another little chip off the huge drought we are dealing with here. Keep in mind rainfall deficits are in the 21 to 29 inch range across the northern half of the state for 2007.
NEXT WEEK AND BEYOND: The rain moves out early Monday morning, followed by a sharp change to colder weather for the first few days of next week. Out in the land of voodoo, the GFS shows a nice snow event for northern Tennessee and Kentucky around December 8, and several shots of pretty cold air coming down this way through December 12. Looks like temperatures all average below normal for the Deep South for the next few weeks.
