Scattered snow showers likely will continue to dust the Rogue Valley today and pile up the white stuff in the mountains, the National Weather Service predicts.

Scattered snow showers likely will continue to dust the Rogue Valley today and pile up the white stuff in the mountains, the National Weather Service predicts.

The weather service's Medford office has issued a snow advisory that remains in effect until 4 p.m. today. The advisory warns of localized showers that can be quite heavy, limiting visibility and blanketing roads.

Meteorologist Marc Spilde said that a cold front moved through the region Tuesday night, delivering freezing weather and precipitation.

A light rain that froze and was then covered with snow created slippery conditions this morning. Fire and police departments across the valley reported numerous fender benders and cars sliding into ditches, but no serious crashes.

Medford police sent out an early morning warning that asked people to limit unnecessary driving, but noted that public works crews were sanding to keep streets as safe as possible. The Medford Fire Department called out additional four-wheel-drive vehicles to ensure they could reach houses on the flanks of Roxy Ann Peak where snow accumulation was deepest.

Another snow shower moved through Medford this morning, Spilde said. Since midnight, the Medford airport got 11/2 inches of snow. Across the valley, snowfall ranged from about half an inch to 3 inches, with the foothills in east Medford reporting the most snow locally, Spilde said. Eagle Point reported 2 inches of snow.

The Oregon Department of Transportation reported 2 inches of new snow on the Siskiyou Pass. There is packed snow on the highway and travelers must carry chains.

Sexton Pass has an inch of new snow, and packed snow on the interstate is breaking up into slush, but snow showers severely limit visibility at times.

Chains are required on large and towing vehicles traveling on Highway 140 between Medford and Klamath Falls and on the Greensprings Summit on Highway 66, the Oregon Department of Transportation reported.

Sporadic showers will continue this afternoon and snow could pile up at elevations above 1,000 feet. The advisory forecasts another 1 to 3 inches.

Overnight, another storm system will move in off the Pacific, Spilde said. It will bring more precipitation, but slightly warmer temperatures. A chance of snow in the valley is most likely before 10 a.m. Thursday. Then snow levels will rise to 2,000 feet by afternoon, so snow will only collect on hilltops.
