Sparkling Weather Ahead

The coolest air so far this season continues to flow into Alabama on brisk northwest winds this afternoon. Checking our SKYCAM site at Cheaha State Park (Alabama's highest point just south of Anniston), we are showing 72 degrees with a cobalt blue sky. The high on the big mountain today so far is only 72.

We are still projecting an average low of 50 degrees by daybreak tomorrow, but of course the range will probably be from abour 45 in the cooler valleys to 55 on the ridgetops. Thursday morning should be about 2 or 3 degrees cooler in most places.

QUICK CHANGES BY FRIDAY: Moist air will surge northward on Friday, and we will bring back a chance of showers and thunderstorms Friday afternoon into Friday night. The system responsible for the rain opportunity will be weakening, however, as it moves from the plains toward the Great Lakes. This will mean no significant chance of severe weather, and probably no especially heavy rain. But, there is no doubt some high school football fans will have to dodge raindrops for the first time this season Friday night.

THE WEEKEND: A surface front will stall northwest of Alabama as it becomes parallel to the upper air winds, and we will have to maintain a chance of scattered showers and thunderstorms on Saturday and Sunday with warm and humid conditions. No total wash-out, but a shower or storm will be possible at just about any time over the weekend. Highs will be in the 80s, and dewpoints will stay well up in the 60s (quite a contrast to the continental Polar air rolling in here this evening).

NEXT WEEK: The GFS finally moves dry air back in here during the day Monday. A stray shower will be possible Monday morning, but we should be in sunshine by Monday afternoon, and at this point the middle part of next week looks dry.

LONG RANGE: Check out the video today and see the 12Z GFS output for October 1. If that happens to be correct, that setup could bring a risk of severe weather, and get us down in the 30s after the upper trough passes. But, as we all know, that is in voodoo land and there is no skill in a specific forecast that far in advance.

TROPICAL: Hurricanes Gordon and Helene will remain far out at sea, and the systems that show up on the GFS remain open Atlantic storms for the next two weeks.

David, Jason, and J.B. did a great job.

Once again, I will try to post some thoughts on the coming winter season here on the blog by 9:30 or 10:00 tonight. The next map discussion video will be posted by 7:00 a.m. tomorrow!
