Monday will be worse: Some locations could see 110 degrees

The heat wave sweltered past 100 degrees Sunday in much of Snohomish County and Western Washington.

EVERETT — Abnormal heat continued to wilt Snohomish County and the entire Northwest on Sunday, sending people flocking to air-conditioned buildings and bodies of water. 

Monday was expected to be worse. An excessive heat warning for Western Washington, with forecast temperatures in the upper 90s and possibly higher, was extended through Tuesday by the National Weather Service in Seattle.

The forecast high for Everett on Monday is 99, but farther east in Snohomish County the temperature could reach 110 degrees.

Over the weekend, temperatures reached the upper-90s in Everett and other areas near the water, but inland highs soared past 100 degrees in places such as Marysville, Lynnwood, Monroe, Snohomish and Lake Stevens. Darrington reached 107.

To the south, even locations near Puget Sound reported triple digits. The temperature at Seattle-Tacoma International Airport reached 104 Sunday, breaking the record for that location. It was the second straight day of triple digits there, a first since record-keeping began.

Portland had it worse. Temperatures there exceeded 110 degrees in some places. And east of the Cascades, in the Tri-Cities of Pasco, Kennewick and Richland, 115 degrees was reported late Sunday afternoon.

Tuesday will likely bring temperatures in the upper 90s in many locations, the weather service said.

Some relief is coming later this week, with highs in the low 90s and 80s.

Officials continued to warn that the hot weather is more than just uncomfortable as many libraries and senior centers opened to provide relief to those most vulnerable.

“Heat stroke is an emergency!” the weather service said in the posted excessive heat warning. “Call 911.”
