Frost Advisory in Effect Tonight
Skies will gradually clear overnight, and this lack of cloud-cover combined with light winds will allow temperatures to fall into the mid-to-lower-30′s by sunrise Saturday, resulting in the possibility of frost, particularly in the usual cold sheltered valleys.
A frost advisory is in effect for all of North Alabama and Southern Middle Tennessee from 4AM to 9AM Saturday morning.
