KNOXVILLE, Tenn. (WVLT) - The heat quickly returns, but luckily the humidity is slower to build back up. This leaves us climbing several degrees each day, to reach 100 degrees Wednesday. This is a First Alert Weather Day, because 90s for highs are common this time of year, but triple digits are not, and this is the hottest day in a decade!

Monday stays mostly sunny with low humidity once again, but we’re back to the upper 80s to 90 degrees for the afternoon. With very little movement in the region, an Air Quality Alert in effect all day for Knox and surrounding counties. A Code Orange for Air Quality means sensitive groups may want limit strenuous activity outside, which includes children, elderly, and anyone with heart or lung disease.

The low humidity lets the heat drop quickly this evening, and fall to another mild night of 60 degrees tonight.


You might feel the slightly higher humidity for Tuesday, but the heat also builds to a high of 95 degrees. It’s still mostly sunny.

Another 5 degree jump to the next day’s high puts Wednesday at 100 degrees. Reaching 99 or greater in Knoxville doesn’t happen often, so that’s why we have this day highlighted as a First Alert Weather Day. It will still be sunny and dry.

Actually most of the First Alert 8-Day Planner is dry, which means the next Drought Monitor is likely to show the heat continuing to dry out the ground. We’re in the mid 90s, for the most part, Thursday into next week, with only a spotty shower or storm. We could see scattered rain and storms next Sunday night into Monday, and we’ll keep you updated on that trend!
