KNOXVILLE, Tenn. (WVLT) - Thursday’s cold front brings rain and gusty storms. A WVLT First Alert starts late in the afternoon when the front moves in, and then the cooler air settles in tomorrow.


Rain and isolated storms are developing at times ahead of the front, through the afternoon hours. Some sunshine breaks out in the afternoon, but that just fuels the storms later. We top out around 72 degrees ahead of the storms.

The cold front moves in bringing scattered downpours and isolated stronger storms late afternoon through the evening. We’ll climb to a 60% coverage in the evening. Wind gusts can pick up to around 20 mph, but a storm could have winds gust up to 40 mph at times. Now, some stronger storms can gust to 45+ mph, plus have some very heavy rain in spots. A WVLT First Alert is in place from 4 to 9 PM.

Tonight will get back to a partly cloudy view by the early morning, with a low around 50 degrees.


We’ll wrap up the week with highs back in the mid 60s. There are some breaks in the clouds Friday, but the afternoon looks mostly cloudy with spotty rain.

If you’re planning some fall fun or festivals this weekend, we’re looking at sunshine on Saturday and a nice seasonable high of 70 degrees. Isolated rain could pop-up Sunday, and it’s looking warmer at 77 degrees. This warm-up is ahead of some more showers next week.

Meanwhile, the Vols are on the road for Saturday’s game. In Alabama, it will actually be closer to 80 degrees for the high on Saturday. In your I’m All Vol forecast, the 7 PM game cools through the 60s with a clear sky.

We’ll be in the mid-70s again Monday, with increasing rain and storms again in the late afternoon to evening hours. This carries over showers into Tuesday, and then temperatures are pushed back down again.
