Winter Weather Advisory Tonight/Tomorrow

10:25 PM Update: If you’re wondering why some counties south of the Tennessee Valley are “in” while you are “out” of the advisory, it’s because there is different criteria for a Winter Weather Advisory for each NWS office. The Huntsville NWS office issues a Winter Weather Advisory for at least one inch of snow; Birmingham issues it for a quarter-inch of snow. -Jason

In anticipation of some minor accumulations of snow and near or sub-freezing temperatures the National Weather Service has issued a Winter Weather Advisory for Jackson, DeKalb, and Franklin (TN) Counties from 9PM tonight through 12PM Saturday. The National Weather Service in Birmingham has also posted a Winter Weather Advisory for several counties in Central Alabama.

Even though major accumulations of snow are not expected., a few slick spots may develop late tonight/early tomorrow morning, especially on the bridges and overpasses in the higher terrain of Northeast Alabama and Southern Middle Tennessee, where the temperatures will be cooler.

The full text from the National Weather Service can be found below. Even though we are not expecting a major winter storm tonight, we will be on top of any potentially hazardous travel conditions that may develop, keeping you updated on-air and online: WHNT.com, Facebook, Twitter, and here at ValleyWX.com.
