We are experiencing a rare back-to-back showing of 80-degree days for this time of year. So, why not? Ditch some of your responsibilities and get outside today.
Thursday’s a good day to play hooky if you’re a warm-weather enthusiast. It’s almost certainly the last day of 80-degree temperatures we’ll see until spring, according to the National Weather Service in Seattle.
“We have one last day of summerlike weather to deal with and then it’s onward to fall as we know it,” weather-service meteorologist Dustin Guy said. “So if you’re a fan of the warm weather, get out there today and if you’re not, wait 24 hours. “
On Wednesday, the temperature hit 80 degrees at Seattle-Tacoma International Airport and is expected to reach 83 degrees Thursday, 16 degrees above the 67-degree average, Guy said.
“Climate-wise, it’s very unprecedented to have two warm days back to back. It rarely happens,” Guy said. The last time was in 1987, when it reached into the 80s on Sept. 30 and Oct. 1.

This week’s warm weather is due to a strong ridge of high pressure over us and an offshore flow that keeps marine air out of the interior, Guy said.
But it won’t last.
By Friday, temperatures are expected to drop 20 degrees, he said, taking us from “well above the average to well below.”
The weekend’s weather will be cool and unsettled, with daytime temperatures in the 60s and overnight lows in the low 50s, the weather service predicts, and the following workweek will be much the same.
Monday and Tuesday may be a little drier, but it will continue to be cool and cloudy with highs in the lower 60s and lows dipping down into the 40s.
“Temperatures in the 70s and 80s will be a thing of the past probably, it’s a good bet, until next spring,” Guy said.
While rain is inevitable, Guy said we should hope October is not as wet as last year’s, which was the wettest on record with 10.05 inches of rain, almost three times the average.
“We don’t want that to happen,” Guy said, “but so far the first week of October looks pretty normal.”
