August 27, 2021 #TriCitiesWx Forecast

The sunny and hot weather will continue for the next few days, but a change is possible as we get into next week. Welcome to the Tri-Cities Weather Blog forecast for this weekend!

A dome of high pressure is locked in over us, and generally when that happens, a tropical storm is the only thing that will change the situation. That may well happen, as Tropical Storm Ida heads for landfall along the Gulf Coast as a hurricane early next week. It’ll be a day or two after that before storms from it will get here after that, though. Here’s the outlook to fill the time before that:

  • Tonight-Partly cloudy, after a couple evening storms depart. Low 68.
  • Saturday-Mostly sunny. Pop-up showers and storms are possible in the afternoon. High 92.
  • Sunday-Sunny and hot, a small chance of a shower or thunderstorm in the afternoon. High 93.
  • Monday-Mostly sunny, with a small chance of rain or a thunderstorm. High 92.

The blocking pattern we have going on will keep fronts from coming in, so sunny and hot weather with stray showers and storms in the afternoon being our forecast with low 90s for temperatures through Monday.

What will be Hurricane Ida likely makes landfall along the Gulf Coast Monday morning. It could be a category 2 or 3 storm, which would not be good for anyone where the storm hits. That system pushes the high pressure out of the way, bringing a good chance of rain and thunderstorms Tuesday and Wednesday at least.

Those storms will not bring as much intensity as the Gulf Coast will see, because hurricanes typically lose the intensity over land that they typically gain over the hot water in the Gulf of Mexico. So, more likely what will see is rain and storms moving into the area, perhaps Tuesday and Wednesday at this point. Individual storms might bring damaging wind gusts, but most likely nothing like the sustained winds in triple digits that the hurricane normally brings to the coast.

One thing that the storm will do is provide us with a good supply of cloud cover. So as we get to the middle of next week, the start of September might have cooler temperatures because of the clouds and rain. There’s a lot of time before all of this, so make sure to check for my forecast on Sunday afternoon for more details.

Meanwhile, we’ll be at the Appalachian Fair with two booths representing all of our stations in commercial building number 1! It’s the one at the top of the hill, and it’s got air conditioning! So take a break from the heat outdoors and say hello to us! We’ll be there through 8 PM Friday and Saturday afternoon until 8 in the evening as well. Have a great weekend!
