Morning lows as cold as 10 degrees Sunday
HUNTSVILLE, Ala. (WHNT)– It was a bitterly cold start to the second half of the weekend across the Tennessee Valley.
Thanks to a clear sky, dry air and a light wind, temperatures plummeted well into the teens. Winchester was the coldest out of the areas where we can get a reliable temperature reading. The thermometer dipped to 10 degrees there!
Other communities in southern Tennessee also threatened single-digit lows this morning; Frankewing in Giles County dropped to 11 degrees, while Huntland settled at 12.
Temperatures across north Alabama weren’t much higher this morning. Valley Head in DeKalb County, a notorious cold spot in the Tennessee Valley, dropped to 14 degrees. Crossville, Russellville and Cullman all reached 17 degrees. Huntsville’s official low was 20 degrees, though a thermometer on Redstone Arsenal shows 15 as the lowest temperature Sunday morning. Muscle Shoals’ official low was 21.
The main reason why temperatures were able to get so cold was the snow pack to the north of us. Although the wind became much lighter last night, it was still generally out of the north. This meant the cold air blowing toward us over the snow pack was not able to moderate, so you may have noticed an extra bite to the air early this morning.
The expansive snow pack could be seen across more than a dozen states on visible satellite imagery Sunday morning.
