A stiff south wind overnight brings in air that sets us up for a heavy rain event that may feature a few marginally severe thunderstorms late Saturday night into Sunday morning. This does not look anything like the tornado outbreak from November 30th. Following the rain and storms, it gets darn cold on Sunday: temperatures dropping into the low-30s with a wind chill around 15 to 25 degrees. Some rain may mix with sleet and snow, but we do not anticipate any significant accumulations of snow or ice (although some slick spots may develop on roads that do not dry well after heavy rainfall).
More on the stormy weather: Some light showers develop overnight through Saturday morning, and Saturday does look like a breezy, mild, occasionally-rainy day. Total rainfall through 10 PM will range from a few hundredths of an inch to as much as one-half inch from scattered, on-again, off-again showers.
The Storm Prediction Center has outlined a low-end risk of severe storms from southeastern Texas to the Tennessee Valley from Saturday evening into Sunday morning.
We believe the greatest threat of any legitimate severe weather is west and southwest of the Valley, but we need to be on alert for heavy storms that might have a shot a producing some strong winds between 10pm Saturday and 7 AM Sunday. The Storm Prediction Center notes that the higher probability of any tornadoes would be in Louisiana and Mississippi; the threat is not exactly zero for the Tennessee Valley, so we’ll keep watch for you as always!

Heavy rain to wintry mix? We expect a solid 1-3″ rainfall across North Alabama and Southern Tennessee Saturday through Sunday morning, and as that rain ends some sleet and/or snow may mix with it for a brief period. Temperatures will plunge to the low 30s with a strong northwest wind making it feel more like the upper 10s and lower 20s:
We do not expect significant wintry precipitation: no winter storms, very little if any impact whatsoever. A few slick spots may develop in areas where roads have a tough time drying off after heavy rain. We’ll get around 1″ to 3″ total, so there’s certainly a chance of some icy spots Sunday afternoon through Monday morning.
