It’s been an active past few days across the Tennessee Valley with multiple rounds of heavy rain and thunderstorms, leading to flash flooding in some areas. Just since early last evening, a large part of southern middle Tennessee has seen near or over 2 inches of rain, with a large swath of 4 to 6 inch rainfall estimates along the Highway 412 corridor. Additional rainfall estimates of 2 to 4 inches have been common in Limestone, Madison, and Morgan Counties in north Alabama with widespread 1″+ rain estimates covering the vast majority of north Alabama elsewhere. Heavier rain has shifted off to our east for now, but we are not done with the rain chances just yet!
More scattered showers and storms are possible as we head through the evening and overnight into the early morning hours. Where they happen, there could be some heavy rainfall, loud thunder, and maybe a bit of gusty winds, but we are not expecting severe storms or a tornado threat overnight! Scattered storms will be possible at any time during the day on Thursday, but they will be much more scattered in nature than the past few days. Things begin to calm down by later Thursday night with the loss of daytime heating.
A few more isolated thundershowers are possible on Friday, but deeper moisture will be shifting out. We shift back to drier weather for the weekend into early next week as an upper low sets up over the Appalachians and pulls drier air into the area. Daytime highs in the lower 80s the next few days ease back into the mid 80s as we head into next week.
