Maybe it won’t be a white Christmas after all, but there’s a pretty good chance of a white weekend, with as much as 3 to 5 inches of snow possible in Seattle and much of the Puget Sound region.
The National Weather Service defines a white Christmas as having at least an inch of snow on the ground at 4 a.m. Dec. 25. This year, snow is most likely to fall between Saturday night and Sunday night, NWS Seattle said on Twitter.
Weather-service meteorologist Carly Kovacik said the snow won’t arrive in a single storm, but rather in a series of rain systems starting Thursday morning. After a period of clear weather, the second system in the series will move down from the Alaska Panhandle and the B.C. coast, arriving over Western Washington late Thursday and Friday.
On Saturday and Sunday, a set of smaller rain events, combined with colder temperatures, is expected to bring some “sustained snow,” she said.
In Seattle, there’s a “greater than 95% chance” of seeing an inch of snowfall between 4 p.m. Saturday and 4 p.m. Monday, and a 60% chance of seeing 4 inches, the weather service said.
“BOTTOM LINE: Much of the lowlands could see 3-5” of snow in the most likely scenario,” the weather service tweeted.
