EVERETT — For those who pay attention to weather records, feel free to celebrate with a swig of ice water before reading this.

As of 2:30 p.m. Monday, Everett’s Paine Field reached 88 degrees, eclipsing the previous high of 87 degrees set July 8, 2010, according to the National Weather Service.

Except it’s not really an official record because Paine Field is not a recognized weather station, said weather service meteorologist Dev McMillian on Monday.

“I guess it broke an unofficial record,” McMillian said. “It’s the warmest temperature on this day.”

Speaking of warmth, the overnight low through 4:30 a.m. Monday was 73 degrees at Paine Field.

“In 76 years of records at this location, a low temperature at or above 70 degrees has occurred just twice,” the weather service wrote on X.

And it’s likely today’s “unofficial record” will rise a few more degrees before cooling down for the night.

As of about 3 p.m. Monday, other stations showed temperatures ranging from 83 in Marysville, 91 in Lake Stevens and 97 in Darrington, according to the weather service.

One more piece of bad news for those who don’t like it that warm: A heat advisory, originally scheduled to end Tuesday, has been extended until 5 p.m. Wednesday. Hot conditions that could reach into the mid to upper 90s in some areas will pose a moderate to major risk of heat-related illness. By Thursday, forecasters predict a slight cool-down with temperatures dropping to the low 80s in much of Snohomish County.

It could be worse. On Monday at 3 p.m., the temperature in Death Valley, California, was 124 degrees.
