Eastern Washington is bracing for another round of sizzling summer weather, with temperatures expected to reach 100°F on Monday, September 11, and remain in the upper 90s throughout the week.

Scorching Forecast: 100° Heat Returns to Eastern Washington

Tri-Cities,  Walla Walla, and Yakima will feel the heat the most. While September usually brings a break from the scorching sun, this forecast says otherwise.

Here's what to expect according to NOAA:

• Monday (9/11): 100°F+

• Tuesday–Friday: Upper 90s

• Warm overnight lows in the 60s–70s

The all-time high temperature in the Tri-Cities was 118°F, recorded on June 29, 2021, so it looks like we won't hit any record temperatures over the next few days, but look for Monday to be a triple-digit heat day with the rest of the week

As we start next week, are we getting one last spurt of summer? I think so.
