Those who like very hot weather: Get outside for the last day of what is likely the last heat wave of the season. For others, including older people and others sensitive to the heat, take care.

It is not expected to last. Sunday’s high temperature in Seattle reached 90 degrees, according to the National Weather Service. It kicked off a two-day mini-heat wave, with temperatures Monday also expected to be in the upper 80s and mid-90s, according to Gary Schneider of the National Weather Service in Seattle, which announced a heat advisory through Monday. The risk is moderate for those sensitive to the heat.

Yet another heat wave grips parts of US West

The hottest temperatures will extend south from Seattle through Tacoma and Olympia, reaching Chehalis, and east to the foothills of the Cascades.

The heat wave will not be as hot or as long as the recent six-day streak of hot temperatures, which climbed to the upper 90s. And, Schneider said, there are no more heat waves on the horizon.

Once we get to the middle of August, the chance of temperatures getting into the 90s starts going down, according to Schneider. “We’re kind of in the peak of the hot season right now,” he said.

“On Tuesday, we’re back into the low to mid-80s, which is slightly above normal, but cooler,” Schneider continued. “And then on Wednesday, we’ll actually be below normal.”

That’ll mean the temperature in the 70s, with potential rain showers and thunderstorms possible. Temperatures are expected to rebound late in the week, according to the National Weather Service, with dry days forecast for Thursday and Friday bringing highs in the low 80s.
