KNOXVILLE, Tenn. (WVLT) - A summery ‘holding pattern’ of low rain chances and increasingly hot weather is here to stay for at least the next week. We’ll have a good shot at our first 90 degree day all year.

About the best rain chances in the coming ten days are just around the corner, so keep reading to learn more!

WHAT TO EXPECT

In short, you can expect to crank the A/C on, if it’s not already plugged in. Tonight is pretty dry with just a couple of showers in Northeast Tennessee.

Tuesday is warmer earlier in the day. There’s a better ‘bullseye’ for a few smaller afternoon storms: you’ll find that towards Claiborne and Hawkins County, plus the Cumberland Gap and the Tri-Cities. That’s closer to a coin flip for rain. The rest of us – outside of that likely zone – should stay dry.

Wednesday is nearly identical to Tuesday – with both the rain zone and timing, plus the muggy and hazy feel. It’s maybe 2 degrees warmer but that’s about the only change as the blocking pattern continues to strengthen over the Smokies.

LOOKING AHEAD

Rain chances all but disappear after that, but the cicadas and allergens should both pick up. The ground temps will be much, much warmer, triggering both of those to emerge faster.

We have hazy sunshine Thursday and Friday. Any and all rain chances this weekend, which are very low by the way, should be high atop the Smoky Mountains peaks.

Our first 90 degrees in the forecast of 2021 come next Monday and Tuesday. One note: that’s the forecast for Knoxville. Those at higher elevations will not be *quite* as hot.

Temperatures will flirt with 90 degrees by the upcoming weekend.
