Icy conditions contributed to a wild night on Jackson County roads Tuesday, police said.

Icy conditions contributed to a wild night on Jackson County roads Tuesday, police said.

"Wrecks started picking up as the road became more icy," said Jackson County Sheriff's Sgt. Marty Clark. "I expect it to get worse before daylight."

Several crashes were reported on Highway 140 and Highway 62, police said. Clark said he experienced slick roads in downtown Medford.

"We advise people to stay home and not go out unless they have to on nights like this," Clark said.

Oregon State Police dispatchers said the Siskiyou Summit remained open at 10 p.m. Tuesday night, though steady snow had fallen on the pass throughout the day.

National Weather Service meteorologist Frederic Bunnag said only trace amounts of snow hit the valley floor. One man did call in to report nearly an inch and a half of accumulation on the outskirts of Talent west of Highway 99.

"It had rained earlier and the temperatures dropping to below freezing created the ice on the road," Bunnag said.

A second band of storms was predicted by around midnight that could've brought more snow.

Forecasters are calling for slight chances of snow in the Medford area until Thursday. The predicted highs could reach the mid-30s, Bunnag said.

"The temperatures still could drop to below freezing at night, keeping the icy conditions," Bunnag said.
