Winter Weather Advisory Tonight/Tomorrow

Posted on: 2:44 pm, March 1, 2013, by , updated on: 10:26pm, March 1, 2013

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.
