Knoxville is starting the day in a haze, with patchy fog cutting visibility in some of the valley spots and readings hovering near 34°F at local observing sites. By this afternoon, though, the gray should give way to partly sunny skies, a high near 67°F, and light southerly breezes for a late-winter day that feels more like early spring.
Afternoon And Tonight
Through the afternoon, expect partly sunny skies with a high near 67°F and south winds around 0 to 5 mph, so it will feel mild rather than blustery. Tonight turns mostly cloudy, with temperatures only slipping to around 54°F. Southwest winds pick up to 5 to 10 mph, and gusts could reach 25 mph, enough to rattle any loose backyard decor or trash can lids. According to the National Weather Service Morristown, this morning's fog should stay patchy and mainly confined to the valleys.
Midweek Rain And Gusts
On Wednesday, winds step up a notch, with southwest breezes of 10 to 15 mph and gusts up to about 30 mph, especially across the mountains and foothills. A chance of showers moves in late Wednesday night. The best shot at steadier rain, along with the highest odds for showers and thunderstorms, arrives Thursday night into Friday, when rain chances climb into the 50 to 70 percent range.

Weekend Outlook
Showers and a few thunderstorms are likely on Friday, with highs near 69°F ahead of a cooler push of air over the weekend. Saturday should top out in the upper 50s, and Sunday into Monday will feel noticeably colder, with highs mainly in the 40s and overnight lows dropping toward the 20s by Monday night. Forecasters note that any stronger storms Thursday night into Friday could bring brief heavy downpours and gusty winds, but widespread severe weather is not expected. The National Weather Service Morristown advises keeping an eye on updated forecasts if you have travel or outdoor plans late in the week.
What This Means For Your Plans
Short sleeves might work this afternoon, but do not forget the umbrella for late-week outings. Secure loose patio furniture, grills, or decorations before the gustier periods roll in, and give high-profile vehicles a little extra room on exposed stretches of road. If you are heading into the foothills or mountains, expect the earliest showers and strongest winds there, and check local conditions before you go if your plans are sensitive to changing weather.
