Seattle area poised for ‘record high heat’ this weekend

Temperatures will start to climb in the mid-1980s on Friday. By Saturday and Sunday, the region will warm to “potentially dangerous levels” in the Seattle and Olympia area, according to the National Weather Service.

The NWS issued an excessive heat warning effective Friday through Monday afternoon for most of western Washington, the Cascades and most of the Peninsula.

The highest triple-digit heat probability on Saturday will be “primarily for interior areas of Tacoma to the south,” according to the NWS. Sunday will likely be “a repeat of Saturday” for the most part, although there is still a chance that the 100 degree temperatures will move “just slightly north.”

Historically, Seattle has only experienced temperatures of 100 degrees in June once, on June 9, 1955, hitting three digits in total on three occasions. By Sunday or Monday, the region will see what the NWS calls “all-time record heat,” with a chance that Seattle will see its all-time hottest day for any month.

KIRO 7 meteorologist Nick Allard predicts agrees Seattle “will break records every day this weekend,” predicting a record high of 101 degrees on Sunday, then 102 degrees on Monday next week (another record).

“If you watch Sea-Tac, or SEA now, the record has been officially held there since 1945. We’ve only hit 100 or more twice,” Allard told KIRO Radio’s Gee & Ursula. “If you go back to before 1945, the federal building was the official observation post. Seattle only hit 100 twice. So if you go back to our long history of measuring temperature, we only hit 100 or more four times. “

Allard pointed out that if we hit 97 on Saturday that alone sets a record for the hottest June on record.

“It’s madness, I tell you! Allard joked.

Additionally, there is a chance that we could see the mercury reach 100 on Saturday and Sunday.

“If we were to hit 100 two days in a row, that never happened,” Allard said. “If we had to do it three days in a row, it would be on another level. I don’t think we will.

He suspects it will end up being a hotter, drier summer.

All along the West Coast, this is all part of what the University of Washington Cliff Mass climatologist describes as a “mind-boggling” forecast.

“Several global models are predicting an extraordinarily unusual heat wave this weekend in the Pacific Northwest,” Mass detailed in a blog post on Monday. “A heat wave so extreme that many places could experience their hottest temperature on record. “

“The forecasts are just crazy,” he added.

Mass indicates expected highs next Monday around 105 degrees at Sea-Tac and 110 degrees at Olympia, with areas near Richland peaking at 115 degrees.

“Quite honestly, it’s hard to believe my eyes,” Mass said in a second blog post on Wednesday. “This is unprecedented and dangerous meteorological territory.”

The National Weather Service says it will also be very hot in the mountains if your plan was to escape the heat at higher elevations. Indeed, the heat could have major impacts on snow and glaciers.

“Please tread carefully if you leave next week,” the NWS tweeted.
