Clear skies and muggy air greet Nashville this morning, with temperatures near 72F at Nashville International Airport, but the calm is on borrowed time. A slow-moving frontal zone is sliding in and will send rounds of showers and thunderstorms across the area today, keeping rain chances elevated straight through Memorial Day weekend. Scattered heavy downpours could trigger brief urban flooding and throw a wrench into already clogged commutes.
Afternoon Downpours Likely
According to the National Weather Service, showers and thunderstorms are most likely this afternoon and evening, with new rainfall totals of about three-quarters of an inch to one inch possible in the stronger cells. Storms should be most numerous from midday into the evening, and occasional gusty winds and localized downpours could quickly cut visibility and cause ponding on neighborhood streets. Drivers should expect slower travel where the heaviest cells line up with busy roadways.
A Familiar Wet Pattern
This stretch keeps alive a soggy pattern that has already been a nuisance this month. Earlier in May, similar hit-or-miss storms slowed commutes across the city. Read about the storms that snarled May 6 commutes for background on how this setup has been playing out.
Weekend Outlook And Flood Risk
The stalled front and multiple disturbances are expected to keep medium to high rain chances in the forecast each day into the holiday. The National Weather Service notes that total rainfall of more than 2 inches is possible across much of Middle Tennessee through the weekend, with locally higher amounts where storms repeatedly track over the same locations. A system on Friday may also crank up stronger southerly winds, with gusts up to about 25 mph in the more robust storms, before the front stalls again over the region. That combination raises the risk of minor flash flooding in poorly drained spots and could lead to last minute cancellations or delays for outdoor Memorial Day plans.
How To Prepare
Sign up for local weather alerts, keep a close eye on changing forecasts, and build extra time into your commute in case heavy rain slows things down. If you have outdoor plans, line up a backup indoor option, keep rain gear handy, and be ready to pivot if storms roll through at the wrong time.
