The heat is (almost) on.
A massive dome of high pressure bulging up from the Southwest will overtake Seattle this weekend, sending the mercury soaring more than 20 degrees above average. High temperatures at Sea-Tac Airport, where the city’s official weather readings are taken, should be hugging the upper 60s this time of year. Instead, we’re likely to flirt with 90 degrees by Sunday.
Exactly how warm will it get? To the audience we go!
