A tropical air mass over the Tennessee Valley means heavy downpours on Thursday afternoon and evening have the potential to drop a lot of rain in a short time: as much as 0.75″ to 1.25″ in less than 60 minutes. The heaviest storms slowly dissipate after 7 PM, and only light, spotty showers and sprinkles last beyond that through midnight.

Scattered showers and storms remain likely at times through the weekend, but we do not expect enough rain to get us out of the drought. Every little bit helps, though. See how the drought expanded to include much of Madison County in the “Extreme” category this week on our Valleywx Blog!
