Tuesday is a First Alert Weather Day for strong-to-severe storms moving in for the evening and overnight hours.
Skies will be mostly cloudy today with scattered rain showers. You may hear a few rumbles of thunder as well, but no severe weather is expected today. Winds will be out of the southwest today around 10 mph. Look for highs to push into the upper 60s this afternoon…about 15° warmer than average. Skies remain mostly cloudy tonight with isolated showers possible.
Tuesday is our first alert day, but the severe threat doesn’t materialize until the evening hours over northwestern AL. During the day, scattered showers are possible and it will be breezy. South winds should be sustained at 10-20 mph with gusts as high as 30 mph. It will be unseasonably warm with highs into the lower 70s.
During the day, strong/severe storms should fire up to our west across north MS. Initially, those storms would head into west TN…but eventually they should form into a line that moves east into the Valley. It's into the evening when stronger storms are more likely to move into the TN Valley.
That line should approach northwest AL after 5-7 p.m. Storms would track east with time and likely wouldn't approach the Huntsville Metro area until after 8 p.m.
The primary threat would be for damaging wind gusts of up to 65 mph. A brief, spin-up tornado is also possible, especially west of I-65. The storm line should weaken as it moves east, but severe weather is still possible for the HSV Metro area as well as northeastern AL. The severe threat does diminish with time into Wednesday morning.
Wednesday will bring a return of cooler weather with breezy west winds and highs limited to the mid/upper 50s. We’ll be into the upper 20s that night as skies clear. We’ll see mostly sunny skies and dry weather to finish the work week. Highs should stay in the 40s for Thursday and Friday with lows dipping below freezing overnight. Temperatures start warming for the weekend.
