PORTLAND, Ore. - An early winter blast of light snow moved into the Northwest Monday as temperatures dropped and higher elevations saw light accumulations of snow.

Snow fell at lower elevations but was not sticking to well-traveled roadways Monday morning. ODOT cameras showed snow falling at many busy intersections and highways, but it was not sticking to most roads.

In outlying areas where the snow was heavier and temperatures colder, schools closed or were delayed, and police were kept busy with traffic problems and stranded motorists.

The snow level is expected to remain low through the day on Monday in the Portland area with temperatures remaining in the 30s or low 40s most places, including the coast.

Outlying areas could remain at or below freezing.

Upper elevation roads such as Highway 26 through the West Hills could see some snow on the roadway, but accumulations are expected to remain very light.

Temperatures are expected to drop Monday night, but any snowfall should be light and localized as only small showers are expected.

In locations east of Cascade Locks in the Columbia River Gorge and in higher elevations, snow stuck to some roads, creating hazards for commuters.

Oregon Department of Transportation crews were out in force Monday with snowplows and other equipment, including a gravel/de-icing combination that has seen success in other areas of the state.

Snow showers or ice may return on Thursday, when another weather system combines with cold air in the region.

KATU Meteorologist Rod Hill says a strong weather system coming in off the Pacific Ocean could meet cold air coming out of the Gorge, possibly setting up a scenario for snow or light freezing rain in the region on Thursday.
