A line of thunderstorms is expected to develop and move into the area during the predawn hours, part of a vigorous storm system affecting a large part of the nation's heartland.
A deepening surface low will track from the Plains to the western Great Lakes region by late tonight, bringing high winds, rain, and snow to a wide area. Blizzard warnings are in effect for parts of Iowa and Minnesota for tonight.
The cold front trailing from the low will surge eastward during the night, triggering a line of potentially severe thunderstorms that will cross the South just ahead of the front. The prime area for severe will extend from northern Mississippi through Tennessee and Kentucky, including a small part of western Alabama. The main threat will be damaging winds, though a few tornadoes cannot be ruled out.
The line should weaken some as it approaches east Alabama, but should hold together enough to bring heavy rain, considerable lightning, and possibly high winds to our area. A slight risk for severe weather extends barely into the western part of the News3 coverage area.
The front will follow the storms and clear us out by Friday afternoon in most areas. Air behind the front will be Pacific in origin, bringing a return to seasonable temperatures for the weekend.
