Clark County residents can expect to see snow throughout the day today — but it won’t be much.
The bigger problem for residents may be the Monday morning commute on icy roadways.
The National Weather Service issued a winter weather advisory Saturday afternoon that covers all of Clark County and the Portland-metro area. Snow will likely hit the region in two waves today, but total accumulations aren’t expected to be more than 4 inches, said Matthew Cullen, a meteorologist with the National Weather Service in Portland.
“The higher elevations will be most likely to see more, lower elevations are more likely to see less,” he said.
The first round of snow will arrive this morning, between 5 and 8 a.m., Cullen said. Those in the higher elevations of Clark County can expect to see the snow first, he said.
Temperatures will reach the upper-30s before cold air moves in, bringing another wave of snow in the late afternoon and evening. Areas above 500 feet will see a total of 1 to 4 inches of snow. Those below 500 feet won’t get more than about an inch, Cullen said.
The accumulations may also vary depending on where the cold air sets up, Cullen said. But whatever snow does fall Sunday will freeze overnight. Temperatures will drop to about 25 degrees in Vancouver and the lower 20s in outlying areas, he said.
“Any moisture that’s left will likely freeze with overnight temperatures that low,” he said.
Conditions will improve Monday as the sun comes out and temperatures climb to the mid-30s. Monday will be dry, but any residual moisture from Sunday is at risk of refreezing Monday night, Cullen said.
Overnight lows will be in the low 20s, possibly the teens, bringing Clark County its coldest night in months, he said.
“Plan for those temperatures because this will be quite cold,” he said.
