Nashville is starting the day on a deceptively pleasant note, with clear skies over the airport and temperatures near 68°F. Do not get too comfortable. Humidity is already creeping up, and by midafternoon the city will feel hot and muggy, with highs near 93°F and a heat index pushing into the upper 90s. Late tonight, a line of showers and thunderstorms is expected to roll in from the northwest, bringing gusty winds and pockets of heavy rain that could briefly snarl traffic and put a damper on outdoor plans.

Afternoon Heat And Humidity

Temperatures are on track to climb into the low 90s, with south winds around 0 to 10 mph and gusts that could reach 20 mph. The heat index may top out in the upper 90s this afternoon. According to the National Weather Service, the mix of heat and humidity will make midday outdoor activities pretty uncomfortable, so plan on frequent breaks, shade when you can find it, and plenty of water.

Late Night Storms And Monday Rain

Forecasters expect scattered thunderstorms to fire up northwest of the city after midnight, then sweep across Middle Tennessee through Monday morning, with the stronger storms most likely in the overnight hours. Showers and thunderstorms are likely on Monday, and the heavier downpours could drop about a half to three-quarters of an inch of rain in localized spots. Gusts may reach around 25 mph, with damaging winds as the main concern, while the tornado risk stays low.

What To Do Tonight

Keep tonight’s plans loose. Tie down or bring in loose outdoor items, think about shifting gatherings inside, and be ready for brief but intense downpours that can slow traffic or trigger short-lived power or service interruptions. Sign up for Metro emergency alerts and follow preparedness guidance from the Office of Emergency Management for the latest watches and warnings, and check the National Weather Service for updates.

Expect a soggy Monday morning commute as showers hang on into the early afternoon, so build in extra travel time and take it slow in heavier rain. We will share updates if any watches or warnings are issued overnight.
