Thursday Afternoon Discussion Update 4:00 PM

We enjoyed another good dose of sunshine today and the temperatures served as a nice compliment. Temperatures at last report were in the upper 50s, but keep the jackets handy as we will cool quickly after sunset. Another surge of dry air has reached our area and tonight we will drop just below freezing. We will have a light north wind adding to the chill before midnight and then the winds will diminish. Tomorrow the sky will be sunny for the first half of the day and then high clouds will start moving in late. Clouds will continue to increase overnight, with a good chance for showers on Saturday. A cold front will move in on Saturday and it now appears there may be enough moisture and instability for a few rumbles of thunder south of Tuscaloosa. The system will be a fast mover and by Sunday we will have brighter conditions, with cooler daytime highs.

Some really cold air will head out of Canada on Monday and this will send a cold front racing in our direction. Monday will be a dry and seasonal day; however, we will have windy conditions on Tuesday, with falling temperatures. A stray shower can’t be ruled out in advance of the cold air. The big chill will be in place early on Wednesday, with morning lows near 23 degrees. Some areas may only reach the upper 30s on Wednesday.

Another shot of the really cold air will roll in on Thursday. At this time it appears we may have a shower or two before the next cold blast settles in. We will have to keep a close eye on the timing of the precipitation and cold air. If the right combination manages to materialize we may be looking at winter weather possibilities late next week. It’s still way too early to making any calls, but the active pattern and cold air advances will need to be monitored closely. Some of the long range data shows a massive cold core 10454 MB high settling into the plains. This setup would spell lows in the teens for our area late next week! We’ll keep you posted.

Local Waterways: Flood Warnings continue for portions of the Tombigbee and Black Warrior River this afternoon. The included graphic displays the latest stages and crest forecast. Note that the locations with no crest information means that the crest has been reached for those locations.
