The Seattle area should prepare for the possibility of wintry conditions this weekend, according to the National Weather Service.

The weather service issued a special weather statement that snow could fall in Western Washington this weekend, likely in Whatcom, Skagit and San Juan counties. With a forecast low of 32 degrees on Saturday night, Seattle’s temperatures will probably be too warm for snow, according to meteorologist Johnny Burg.

A high-pressure system over Canada will push the cold air into Western Washington from the Fraser River Valley, according to the weather service. Because it’s unknown how far south the cold air from Canada will extend, drivers should be aware of changing road conditions, Burg said.

“The question is how far the colder air will go and if it will be cold enough for snow,” Burg said. “So drivers should be aware the possibility (of snow) exists and prepare for it.”

For Seattleites, the cold air will be a stark contrast to the springlike weather on Friday. The 58-degree high recorded at Seattle-Tacoma International Airport wasn’t warm enough to break the record of 68 degrees from 1968, but it was 7 degrees warmer than average.

The weekend cold won’t last long. A warm front will bring moderate precipitation of a quarter- to a half-inch of rain Sunday afternoon through Monday night, when the forecast high will be in the 50s.

The weather service issued a wind advisory Friday afternoon, effective until 4 p.m. Saturday, for western Whatcom County, including Bellingham and Sandy Point. The northeast 25 to 35 mph wind with gusts near 50 mph is expected to be strong enough to snap small tree branches and cause local power outages.

Across the Cascades, the weather service forecast an unseasonably cold air mass in the region, with light snow starting Saturday night, becoming moderate to heavy on Sunday.
