July 21, 2021 #TriCitiesWx Forecast

Smoke from wildfires out west has drifted into our area via the jet stream, so today’s sunny day wasn’t as sunny as expected! The hazy conditions caused air quality to be worse than normal, too. I’m keeping an eye on that situation in today’s Tri-Cities Weather Blog forecast!

For most, the air wasn’t terrible to breathe today. But if you have sensitivity due to lung issues like asthma, then being outside for a long time could’ve caused a problem. I was out for about an hour today, and my asthma didn’t bother me all that much. It was just hot! More heat is on the way for a while. Here’s the outlook:

  • Tonight-Partly cloudy, with hazy conditions. Morning fog possible. Low 62.
  • Thursday-Mostly sunny, possibly hazy at times as well. Highs near 90.
  • Thursday night-Mostly clear, low 61.
  • Friday-Sunny and hot. Highs near 90.
  • Saturday-Sunny and hot, with a stray afternoon shower or thunderstorm possible. High 92.
  • Sunday-Sunny and hot, a small chance of rain or a thunderstorm in the afternoon, high 92.

The jet stream helped lift (and thankfully, distribute far and wide) the smoke from the wildfires out west up into Canada, down through the middle of the country, then over us. It looks like today was the worst of it from an air quality standpoint, which is good news. Hazy conditions are possible through tomorrow, though.

From there, the forecast goes back to summer heat. It’s likely every day the next four days will be at 90 or above, especially once the smoke clears…literally! I can’t rule out a pop-up shower or thunderstorm on Friday, even though the outlook doesn’t mention it. The better chances of that–which are still pretty small–are for the afternoons this weekend.

Thanks for checking here for the forecast. Happy Thursday to all!
