KNOXVILLE, Tenn. (WVLT) - Slightly above average temperatures and “dog days of summer” humidity continue through the next week.

Eventually this weekend, that high humidity will generate a few showers and thunderstorms. These are totally unorganized and can impact your afternoon and be anywhere on the map. So, have rain gear with you the next several afternoons.

Next week we’re back to the 90s - where we likely will stay for a while.

See below for the new US Drought Monitor. Most of Scott County is in the lowest level of drought.

Friday should have a few more mid-level clouds. That may hold down the temperature 2 degrees or so. That may not be enough to notice, however, as humidity remains even higher Friday. That will keep the feels like temperature in the mid 90s late afternoon Friday. There’s also slightly better chance of rain. This is reminiscent of about a month ago when we had an east to west rain event.

That means that storm should start on the mountain tops, descend of the foothills, linger in the valley, and fizzle out as they go back up hill onto the Cumberland Plateau. Overall though it’s just a 20% chance of rain.

The first half of Saturday looks really nice, albeit more muggy. High temperatures should be from the upper 80s to near 90. After 2 PM rain begins in circling the Tennessee River Valley. These storms could briefly be strong but widespread severe weather is not likely. The coverage is better than in previous days. By late night Saturday about 4 in 10 of our acres have some much-needed rain.


To me, Sunday looks like it will have more clouds and at least the *chance* of more heavier rain, even though the overall coverage is similar to Saturday. Many stay dry while others could pick up half an inch of rain. Rain is back for others on Monday. That’s the 4th of July, also called Independence Day. The rain is trending towards the middle of the afternoon - to be blunt, it’s too early to know exactly when it will rain.

We’re staying at or near 90 degrees during most of the afternoons of next week. The overall chances of rain are pretty small, but definitely not zero.
