Tuesday, March 3, 2026, started off gray and chilly around Knoxville, with patchy fog and temperatures hovering near 43°F. That cool, misty vibe will not last long, though. As the day goes on, the fog thins, skies brighten into the afternoon, and highs climb to around 72°F with a south breeze that turns noticeably breezy at times.
Afternoon Winds Pick Up
As the atmosphere mixes out this afternoon, low clouds lift and winds pick up, with gusts around 15 to 20 mph at times. That could make for a bit of a blustery evening commute. Forecasters at the National Weather Service Morristown say the strongest gusts are most likely in exposed valley and ridge locations.
Late-Week Records
Temperatures take off through the rest of the week, with mid 70s on Wednesday and readings near 80°F on Thursday. By Friday, low 80s are on the table, which is roughly 15 to 20 degrees above normal for early March. Knoxville’s average high in March sits at about 58°F, making this a notably warm stretch for the season, according to Weather Atlas.
Weekend Rain And Thunder Risk
Rain chances return late in the week and ramp up into the weekend. Showers are likely Saturday and Sunday, and there is a growing chance of showers and thunderstorms Sunday night into Monday. Forecasters note that rising humidity and dew points into the 60s this weekend will boost the potential for stronger storms, though no watches or warnings are in effect right now, per the National Weather Service Morristown.
What To Know
Plan on some reduced visibility on area roads this morning where the fog hangs on, and give yourself a little extra time for the drive. You will also want a quick wardrobe upgrade later this week as temperatures surge into much more springlike territory. If you have outdoor plans for the weekend, keep an eye on updated forecasts before heading out, since the exact timing and coverage of showers and thunderstorms could still shift.
