Knoxville wakes up mostly cloudy this morning, but temperatures will climb into the upper 60s by afternoon, with southwest winds gusting up to 25 mph. Expect a warm, blustery day with a high near 68°F before showers move in. Rain is likely late tonight (Tuesday night), arriving after about 11 p.m. and lingering into the early hours of Wednesday, which could leave roads slick for the Wednesday morning commute.
Afternoon Winds Pick Up
According to the NWS Morristown, southwest winds will ramp up this afternoon, with sustained speeds of 5–15 mph and gusts up to 25 mph in spots. Those gusts can jostle high-profile vehicles and cyclists and may send unsecured outdoor items skittering down the street, so use caution if you are driving or biking. It is worth keeping an eye on updates if you have outdoor errands or deliveries planned.
Late-Night Rain And Overnight Warm-Up
Showers are expected to move in after about 11 p.m., with the chance of measurable rain climbing to roughly 90% overnight and most locations picking up light totals of less than a tenth of an inch. Temperatures will fall to the mid-40s this evening, then rebound into the low 50s overnight, so the pre-dawn Wednesday commute could be mild but wet. For background on the multiday warm-up, see our earlier forecast.
Weekend Wind Watch
Looking ahead, forecasters are also eyeing a possible mountain-wave wind event late Saturday into Sunday, when a stronger southerly flow could send especially strong gusts spilling down from the ridges into valley corridors. That threat is still uncertain, so check later updates if you have weekend outdoor plans and consider securing loose patio furniture and trash cans as a precaution. We will publish watch or warning notices if local officials issue them.
