Seattle-area sets mark for longest snowy period in 52 years
The Puget Sound region’s last gasp of snow this week fell Thursday night, with temperatures finally set to warm into the high 30s and low 40s by the weekend.
According to the National Weather Service, Thursday marked the fifth straight day with measurable snow at Sea-Tac Airport, marking the longest such streak since 1969, and the seventh longest streak since records began in 1945.
The great melt
After a New Year’s Eve in the upper teens, a “warm front” moves through on Saturday and a chance of rain starts Sunday.
“As we get into Saturday, we’ll start to noticeably warm through the day so it is going to be cool as we begin the weekend — Saturday morning still looks pretty chilly,” Carly Kovacik, a meteorologist with the National Weather Service, told KIRO Radio. “But as we go through the day, Saturday will actually warm back up toward 40.”
As local meteorologist Michael Snyder pointed out to KIRO Radio’s Charlie Harger earlier in the week, this run of frigid weather is far from ordinary.
“It’s pretty unusual — the last time we were in the mid-teens was 2010,” Snyder noted.
According to the National Weather Service, record low temperatures for Dec. 26 were set at Sea-Tac Airport, Quillayute, Bellingham, and Hoquiam. On Monday, temperatures in the Seattle area dipped down to 17 degrees Fahrenheit, marking the coldest day since November 2010.
Seattle’s high of 23 degrees Monday was the city’s coldest day in 31 years, according to the National Weather Service.
Travel and transportation
Freeways across the region have been continuously treated with anti-icer to “reduce snow and ice build-up as much as possible,” according to the Washington State Department of Transportation. And while salting roads can help remove layers of ice and snow, “salt isn’t effective once temperatures drop to about 15-20 degrees.”
WSDOT crews have also been plowing high-priority highways 24/7.
“Our goal in plowing is to make at least some lanes passable on as many state routes as possible,” WSDOT said on Twitter. “We work off of our priority maps, so the highest-traveled routes will receive the most attention.”

For those looking to use public transit, King County Metro will remain on a limited schedule with their focus on 60 so-called “core” bus routes prioritized for snow and ice removal.
At Seattle-Tacoma International Airport, delays have persisted throughout the week. In total, the airport said almost 1,500 flights were canceled in December, with 80% of them in the final four days of the month.
