A Winter Weather Advisory goes into effect at 12 PM Friday and lasts through 6 AM Saturday. A storm system bringing some light to moderate snow should produce around 1-2″ of snowfall for most of the Tennessee Valley region by daybreak on Saturday. Heavier snow is likely to the north in the Winter Storm Warning areas of Middle Tennessee.
Some school systems have already made the decision to dismiss early on Friday. Check our list for updates throughout the afternoon and evening.
From our discussion on WHNT.com:
The National Weather Service in Huntsville issued a Winter Weather Advisory for Lauderdale, Limestone, Colbert, Lawrence, Franklin (AL), Lincoln, and Moore Counties effective 12 PM Friday to 3 AM Saturday in advance of the snow. The Winter Weather Advisory extends eastward from 6 PM to 6 AM for the following counties: Madison, Morgan, Cullman, Marshall, DeKalb, Jackson, and Franklin (TN).
A load of rain moves in tonight through Friday morning, and there is low potential for some localized flooding as a solid 1-2 inch soaking rain develops. Isolated three-inch rainfall totals are possible through midday Friday. The threat of severe weather stays to our south; however, some thunder and lightning will accompany the widespread rain here in the Tennessee Valley through the night.
A gradual transition from rain to snow begins around midday near US 43 in The Shoals, but it will be around 4-6 PM before the first flake even falls in Huntsville. The change-over time ranges from about 3 to 7 PM around Albertville, Scottsboro, and Fort Payne.
Total accumulations of one to two inches of snow are likely by midnight, and some hazardous travel is to be expected – especially on bridges. Travel will be much worse in Tennessee where the heaviest band of snow sets up; some communities north of Nashville could see over six inches of snow by Saturday morning.
