Knoxville rolled out of bed to mostly cloudy skies and a chilly 52F early Tuesday, March 31, 2026, but the cool start will not last long. Temperatures are set to surge toward a high near 81F this afternoon as southwest winds ramp up. Gusts could reach around 25 mph, so the late-morning and afternoon commute may feel a lot breezier than it did at sunrise.
Afternoon Winds Pick Up
By midday, southwest winds should turn noticeably breezy, generally around 5 to 15 mph, with stronger gusts on exposed ridges and near the airport. Those gusts may rattle unsecured patio furniture, umbrellas, and lightweight yard gear, so bring items inside or tie them down ahead of time. Expect blustery conditions to hang around through the late-day commute.
Wednesday Storm Chance
On Wednesday, April 1, moisture and instability start to climb, and so does the chance for wet weather. There is roughly a 60% chance of showers and thunderstorms between about 8 a.m. and 2 p.m., with showers and storms becoming likely later in the day and continuing into Wednesday night. Most spots should only see light rainfall totals, although isolated heavier downpours and lightning are possible, so have a rain plan ready if you will be outdoors. The National Weather Service Morristown forecast discussion lays out the full timing and expected impacts.
Weekend Outlook
Early April keeps the heat cranked up. Highs stay in the low-to-mid 80s through Saturday, April 4, before a cold front moves through late Sunday and flips the pattern. Cooler air pours in early next week, and the coldest spots could dip into the low 40s Monday night and Tuesday morning (April 6 to 7), raising a frost concern for tender plants. If you have potted flowers or an early garden outside, keep the covers and blankets handy.
Fire Danger And Local Rules
Dry conditions paired with warm, windy weather have local officials on edge about wildfire potential. Knox County’s ban on open burning remains in effect as crews keep watch for any new fire starts. Details on the burn ban and county restrictions are outlined by WVLT. If you see smoke or an unpermitted burn, report it to local authorities rather than trying to handle it yourself.
Plan Ahead
If you are planning to be outside this afternoon or on Wednesday, secure loose items before the gusts crank up and keep a quick-cover option ready for sudden showers. Check updated forecasts and any watches or warnings throughout the day, and postpone outdoor work if thunderstorms start moving into your area.
