That scorching summer heat we've been lucky enough to avoid so far appears to be on its way to Seattle and most of Western Washington.

Driving the news: While much of the week could bring rain and cooler than average temperatures, forecast models are showing a strong upper-level ridge of high pressure developing that could bring above-normal temperatures to the Seattle area starting around Aug. 13, Michael Fagin with Washington Online Weather told Axios.

  • National Weather Service warning coordination meteorologist Reid Wolcott said the heat event, if it happens, is expected to last through Aug. 16.
  • It's not going to be as extreme as the June 2021 heat wave that brought a 108-degree day to Seattle, an all-time high, but several days with highs near 90 degrees cannot be ruled out, according to the National Weather Service.

Yes, but: Temperatures are expected to be cooler than average early this week with a good possibility of rain between Tuesday and Thursday, Wolcott said.

  • Fire risk to the region from the developing ridge will depend in some measure on how much, where and when we get rain, he added.
