Seattle reached 108 degrees Monday evening, setting another heat record, according to the National Weather Service in Seattle.

The new record was set just after 6 p.m. at Seattle-Tacoma International Airport, according to meteorologist Johnny Burg. It’s the hottest temperature recorded in Seattle since at least 1945.

Temperatures hit 106 degrees at the airport at 2:45 p.m. Monday, breaking the previous record of 104 degrees set on Sunday.

Monday’s heat marks the third consecutive day of more than 100 degrees as most of the Northwest continues to swelter under an excessive heat warning.

 The low for Monday was only expected to be in the mid-90s — about 20 degrees above what is typical this time of the year in Seattle, according to meteorologist Jeff Michalski. 

According to the weather service, Olympia, Quillayute and Bellingham also broke their all time records. Olympia and Quillayute reached 110 degrees and Bellingham reached 99 degrees.

An air quality alert is in effect through Monday evening in parts of King, Pierce and Snohomish counties, due to significant spikes in smog levels.

Some relief is expected by Wednesday, when temperatures are expected to drop down into the 80s in Seattle.
