The National Weather Service has issued a heavy snow warning that goes into effect at 10 p.m. and predicts 2 to 6 inches of snow tonight oro Tuesday across Southern Oregon, including in Medford and Ashland.

The warning predicts snow at elevations higher than 1,000 feet between 10 p.m. today and 4 p.m. Tuesday. Elevations above 2,000 feet in the Coast Range and Douglas County foothills could see 8 to 12 inches of new snow pile up. Medford is at about 1,400 feet.

Another cold front is sweeping into the region, hitting the coast this evening and spreading inland through the early morning hours and into the day Tuesday. Snow levels are expected to dip to sea level, but significant accumulations arenít expected there. Snow levels will hover between 500 and 1,500 feet across the region all day.

The forecast predicts that the front will surge through the Rogue Valley between 10 a.m. and 1 p.m. Tuesday, bringing wind and colder temperatures.

Gusty south to southwest winds east of the Cascades and Siskiyous and in the mountains will create areas of blowing and drifting snow that will limit visibility, the snow warning said. Severe winter weather will make travel dangerous, it warned.

The chance of snow continues through the week as a string of fronts moves across the region.
