UPDATE: The National Weather Service in Portland has issued a winter weather advisory that includes Southwest Washington and the Portland-Vancouver metro area. Forecasters expect 1 to 2 inches to fall at the lowest elevations, with more accumulating in the foothills and mountains late Saturday into Sunday. The advisory is in effect from 10 p.m. Saturday to 4 p.m. Sunday, according to the weather service.
Forecasters are keeping their eye on a mass of cold air expected to reach the Northwest on Saturday, bringing low-elevation snow showers to the region for the next few days.
Updated forecast models suggest the cold air may arrive closer to 4 p.m. than 10 p.m. Saturday, as originally predicted, according to the National Weather Service. But snow showers still aren’t predicted to begin until late Saturday night and into Sunday, according to the weather service. At least some accumulation is expected in places, but likely won’t amount to much.
On Sunday, Vancouver’s high temperature is expected to reach 36 degrees, with snow showers continuing throughout the day. About an inch of accumulation is possible, according to the weather service. Similar conditions will stretch into Monday and early Tuesday.
