Sharply Colder Air Arrives Saturday

HAPPY THANKSGIVING! What a delightful day for Alabama… Birmingham reports 71 degrees at 3:00… that is nine degrees above the average high of 62, and 8 degrees away from the record high for November 22, 79 set way back in 1900. The sky is sunny and humidity is low. Nobody is complaining.

We will enjoy one more relatively mild day tomorrow with a high in the mid to upper 60s, but a cold front will pass through the state during the afternoon hours that will bring some clouds, and maybe even a few sprinkles to the northern quarter of Alabama. Measurable rain is not expected, and the weather begins to turn sharply colder tomorrow night.

COLD WEEKEND: Both the GFS and the NAM now have our low at 32 degrees early Saturday morning. The day Saturday will be sunny, but breezy and cold. The GFS is printing a high of only 49 degrees for Birmingham Saturday afternoon, and then we head for the 20s early Sunday, which will be our coldest morning so far this season. Sunday will be sunny and cool with a high in the upper 50s.

FOOTBALL WEATHER: For the high school playoff games tomorrow night, temperatures will drop through the 40s with a chilly north breeze at 7 to 14 mph, but the sky will be generally clear.

Saturday’s Iron Bowl in Tuscaloosa will be dry and cold. The sky will be sunny with a kickoff temperature near 51 degrees. The mercury will drop into the mid 40s by halftime, and could very reach the upper 30s by the final whistle. A north breeze of 10-15 mph will make it feel colder.

UAB will travel to a warmer setting, where they play UCF in Orlando Saturday (11:00 a.m. CST kickoff). The sky will be mostly sunny, with temperatures rising from near 66 at kickoff to around 70 degrees by the fourth quarter.

NEXT WEEK: A dynamic weather system will impact Alabama late Monday night and Tuesday. Run to run consistency has not been that great, and the latest GFS in hand (12Z) isn’t as bullish on severe weather. It hints at potential for strong storms, main in the window from midnight Monday night to 12:00 noon Tuesday. But, with limited instability, and a rather unfavorable surface pressure field, the severe weather threat looks somewhat marginal. But, this will probably change again as we get closer, so stay tuned. Looks like rain amounts of 1/2 to 1 inch are likely.

Colder and drier air returns Tuesday night. See the Weather Xtreme video for the graphics and details.

I will produce the next Weather Xtreme video tomorrow…

Happy Thanksgiving!

**I will produce a Weather Xtreme video later today when I arrive at ABC 33/40**

MILD THANKSGIVING DAY: Happy Thanksgiving from the weather team at ABC 33/40… the good news is that our weather will remain delightful today with ample sunshine and a high around the 70 degree mark. Doesn’t get much better this time of┬áthe year.

TO THE NORTH: A cold front is moving steadily southward over the nation’s breadbasket, and that front will push through North Alabama late tomorrow afternoon. A few sprinkles could accompany the front over the Tennessee Valley region of extreme North Alabama, but the air will be very dry down this way and we don’t expect any measurable rain as the front blows through. We will reach the mid to upper 60s tomorrow afternoon.

COLD WEEKEND: Saturday will be a different kind of day; while the sun will be out in full force, the weather will be windy and cold. Many North Alabama communities won’t get out of the 40s, and a stiff north wind will make it feel colder. Then, by early Sunday morning, temperatures will drop into the 22-28 degree range, with some potential for upper teens for the coldest valleys across North Alabama. It should be the coldest morning so far this fall. The day Sunday will be sunny and cool with a high in the upper 50s.

FOOTBALL WEATHER: Tomorrow night will be dry and cold for the remaining high school playoff games; the sky will be mostly fair with temperatures falling into the 40s during the games with a north breeze of 10-15 mph.

Then, the biggest game of the year in our state is Saturday, and the weather will be cold and dry for the Iron Bowl in Tuscaloosa (2:30 p.m. kickoff). The sky will be clear; the kickoff temperature will be around 51 degrees, falling into the 40s by halftime, and possibly into the upper 30s by the final whistle. A brisk north wind of 10-20 mph will make it feel colder.

SEVERE WEATHER NEXT TUESDAY? Computer model data continues to show a dynamic storm system moving into Alabama Tuesday. The dynamics will certainly support strong to severe storms, but the thermodynamics remain in question. It will all depend on the amount of instability, so we will be watching computer model trends closely in coming days. Much colder air will follow the storms on Wednesday.
