June 17, 2025 Tri-Cities Weather Blog Forecast

Tuesday, June 17

Recently, we’ve popped into a summer weather pattern including well more in the way of showers and storms around the area than we’re used to as we hit the official first day of summer on Saturday. That will be the day we launch all the way into the muggy 90s heat we’re used to in an East Tennessee summer. Welcome to the Tri-Cities Weather Blog forecast through this weekend!

  • Tonight-Some scattered showers and storms still, otherwise partly cloudy. Low 68.
  • Wednesday-Morning fog in spots, but partly to mostly sunny and scattered showers and storms. High 86.
  • Wednesday night-Scattered showers and storms mainly in the evening, otherwise partly cloudy. Low 67.
  • Thursday-Partly cloudy with scattered showers and storms around, ending late. High 84.
  • Friday-Sunny skies after morning fog. High 85.
  • Saturday and Sunday-Sunny and hot. High near 90 Saturday, 92 on Sunday.

The key in the forecast in the next couple of days invoves a “cold” front that will move through on Thursday. Yes, you’ll notice temperatures actually go up from Thursday to Friday. That’s because of fewer clouds, and the front brings briefly lower humidity. That will set the stage for a hot start to summer this weekend.

As it is right now, we’re going to see a good chance of off and on showers and storms between now and Friday. Some days–like today–will feature little rain, others will have more of it. Looks like the more day will be Thurday. That summer front moves through and kicks off lots of rain and thunderstorms.

After that, we’ll see things clear off after some Friday morning fog. Computers indicate deeper heat levels arriving pretty quickly on Saturday, getting us to our first 90 degree reading in a while, and probably the first 90 degree forecast of 2025 on Saturday. We’ll go from there to the low 90s Sunday and probably deep into next week. Pop-up showers and storms (our normal fare this time of year) will come back each afternoon.

This is something we get every summer at some point, so we all know what to do. Make sure the air conditioning works (and if it doesn’t, call now for repairs!), keep refreshments around if you need to be outside, and schedule lots of breaks. In the meantime, spend the next couple days getting indoors when storms approach. Stronger storms could make things interesting Thursday, and I’ll keep an eye on that.

Thanks for checking here for the forecast!
