EVERETT — A hot weekend awaits the Puget Sound region, including the possibility of triple-digit temperatures Sunday.
Kirby Cook, a science and operations officer with the National Weather Service in Seattle, said cities away from the water could break records on Sunday.
“We are expecting in Snohomish County anything as high as 100 degrees,” he said.
Cook said high pressure moving in and offshore flow will bring warm air from east of the Cascades, causing warm, dry weather beginning Friday and spiking during the weekend.
According to Cook, the Aug. 16 record at the nearest climate-data site, Seattle-Tacoma International Airport, is 98 degrees, set in 1967. Seattle isn’t expected to break that record this weekend, but that doesn’t mean other cities won’t.
Forecasters anticipate highs in the mid- to upper-80s Saturday, with temperatures reaching the 90s on Sunday. Inland cities like Monroe and Darrington are expected to peak at close to 100 degrees.
Cook said such highs aren’t unheard of, but they are unusual because Western Washington typically sees its warmest days in July.
Forecasts show temperatures cooling off to the mid-80s Monday and returning to more normal temperatures, in the upper 70s, on Tuesday.
“It is still going to be warm and dry for much of the week, but the hot day is really going to be Sunday,” Cook said.
The weekend weather could pose moderate to high heat risks. Cook advised people who plan to be outside to stay properly hydrated and reduce their exposure by staying in the shade.
“The most important thing is to maintain awareness and pay attention to the forecast,” he said.
