Fog cut visibility across parts of the Knoxville area early Monday, May 4, but the murky start will not last. Skies are expected to clear out, turning the day sunny and warm with highs near 79°F. Southwest winds will kick up through the afternoon, with gusts up to about 25 mph on exposed hills and bridges. Expect a breezy evening and overnight lows in the mid-50s.
Afternoon Winds Crank Up
Southwest winds should run around 5 to 10 mph through the morning, increasing to 10 to 15 mph by midday with stronger gusts later in the day. Lightweight patio furniture, trash cans, and garden décor could get nudged around, and drivers of high-profile vehicles may notice more crosswinds on open stretches of highway. Tonight looks mostly clear with a low near 55°F as winds relax after dark.
Wet Stretch Arrives Tuesday Night
A frontal system sliding into the region will drag in showers and thunderstorms starting Tuesday night and lingering through Thursday morning. The most persistent and heaviest rain is expected from Wednesday into Wednesday night. Areas south of I-40 have the best shot at picking up an inch or more of rain in that window, which will bump up the risk of localized flooding and ponding on roads. Some of the stronger storms could bring gusts up to about 30 mph. For detailed timing and any watches, check the NWS Morristown forecast discussion.
What To Watch This Week
Tuesday should start mostly dry with just a slight chance of a stray afternoon shower and a high near 79°F. The first steady batch of rain and thunderstorms looks to arrive Tuesday night into Wednesday. Wednesday itself is shaping up to be a wet, windy day with highs near 74°F. By Thursday, the front lingers, and cooler air settles in, before a sunnier, drier pattern returns Friday with highs around 70°F.
We first highlighted this developing setup in our May 1 frost threat preview, and forecasters are now refining the timing and flood potential as new data comes in.
If you have outdoor plans, consider shifting Tuesday night into Wednesday events indoors, and keep an eye on the sky before hitting the road. Residents in low-lying or poorly drained spots should be ready for brief urban flooding during the heaviest downpours. This space will be updated if any watches or warnings are issued, and you should continue to monitor local emergency channels and the NWS for the latest advisories.
