Nashville woke to clear skies and about 55°F early Tuesday morning (5:35 a.m. CDT), but the calm will not last. A warm afternoon with a high near 77°F is expected before showers and thunderstorms move in late Tuesday and again overnight.
Afternoon Storms Likely
Scattered showers are possible between 11 a.m. and 1 p.m., with showers and thunderstorms most likely from about 1 p.m. to 3 p.m. South-southwest winds of 5–15 mph will gust as high as 25 mph, and the daytime rain chance is about 60%, according to the National Weather Service.
Heaviest Rain Overnight; Flooding Possible
A steadier, heavier band is expected Tuesday night into Wednesday, with new rainfall totals tonight of a quarter to half an inch and additional rain Wednesday that could add another half to three quarters of an inch. The overall multi-day totals could reach 1.5–2.5 inches, with the highest amounts south of I-40, so expect ponding on roads and minor flooding in poor-drainage areas. Temperatures will fall into the upper 50s tonight, with highs in the mid-to-upper 60s Wednesday as cooler air follows the front.
Plan Ahead for Commutes and Events
Evening commutes and outdoor plans from Tuesday night through Wednesday could be affected, especially where heavier pockets of rain line up with rush hour. Leave extra travel time, watch for water collecting in low spots, and secure loose outdoor items before the wind and rain pick up.
We previously flagged this setup in an earlier forecast, see cool temps and dry weekend, and updated guidance now emphasizes the higher overnight rainfall risk. The National Weather Service describes the severe-weather threat as low, but brief strong gusts and lightning remain possible with any stronger storms, so keep an eye on updates and have a way to get alerts if storms rumble through after dark.
