PORTLAND -- A boundary separating Arctic air and milder Pacific air holds with it the potential for snow in Portland this coming weekend.
All this as we leave behind one of the coldest winter periods of the last 70 years.
"Our weekend forecast continues to be uncertain. A boundary separating Arctic air and milder Pacific air is expected to be right over our heads," explained KGW meteorologist Rod Hill. "If the boundary holds, Portland will see weekend rain and highs in the 40s, while the Columbia River Gorge sees snow and ice with wintry accumulations."
But the other option would be snow showers in the valley, including Portland. That could happen if the boundary pushes further west, Hill said.
Temperatures were expected to drop into the 30s overnight Saturday and Sunday, with highs only in the lower 40s.
"Then on Sunday, the moisture should be a bit more widespread, so some wet snow showers are possible around the metro area," added KGW Meteorologist Nick Allard. "But , I don't expect much and it should be mainly with elevation."
KGW Chief Meteorologist Matt Zaffino said Portland has already had the 11th-coldest December-to-February period since 1941 and winter is not quite over.
