Sunday is a First Alert Weather Day. Prepare for the possibility of strong to severe storms between 2 p.m. and 10 p.m. Sunday.
There is the potential for a severe weather outbreak over parts of Mississippi, Tennessee and Alabama. Make sure you are checking back for the most recent and accurate forecast. We will be providing updated information throughout the weekend on social media, WAFF-TV and our First Alert Weather App.
Forecast guidance is showing a forecast that could lead to long tracked significant tornadoes, large hail, damaging straight line winds and flooding rain. 2-4 inches of rain looks likely as we will see multiple rounds of storms. This is our current thinking on how this forecast will play out based on the most recent guidance.
We will begin Sunday morning with widespread rain and a few storms along a warm front. The morning storms will most likely just produce gusty winds, small hail and heavy rain. After the warm front lifts north into middle Tennessee the air will become increasingly unstable across all of north Alabama.
Shortly after 1 p.m. we expect the atmosphere to become capable of producing severe storms. They will likely develop out west along the Alabama/Mississippi state line between 2 p.m. and 3 p.m. They will quickly track to the northeast at speeds near 70 mph. After 4 p.m. we could see supercell type storms develop anywhere. They could quickly become severe and track northeast.
We expect a prolonged timeframe where we could see multiple severe storms tracking NE at 60 to 70 mph. The final round of storms will likely come from a squall line tracking east ahead of a cold front around 10 p.m.
Stay weather alert and prepare for these possibilities. Again, this is a forecast and we will not know the exact conditions of the atmosphere until the event begins to play out Sunday afternoon. Have multiple ways to receive critical weather information.
The weather for Saturday look great with increasing clouds and highs near 70.
