Advisory Expanded; Widespread Icing Possible
The National Weather Service has extended the Winter Weather Advisory for North Alabama to include Cullman, Morgan, Madison, Jackson, DeKalb and Marshall Counties this morning. A mixture of rain, freezing rain, sleet and snow are moving through the Tennessee Valley now, and temperatures are still far enough below freezing for considerable short-term hazardous travel.
The worst conditions are found over Southern Middle Tennessee north to Nashville. This photo is from Fayetteville via Carleen Massey:
Here’s a look at Hytop Nexrad showing the precipitation type on the left and the “reflectivity” on the right. Areas where sleet and snow are melting while falling through the sky are causing some “bright banding” on the reflectivity. That’s the hotter reds & yellows north of Huntsville:
This mixture ends by Noon, and travel conditions will rapidly improve as temperatures warm into the forties this afternoon.
