A warm front will deliver balmy temperatures and rain to a big swath of Oregon this weekend, but the Rogue Valley won't get as wet as the coast and points north, forecasters said.

A warm front will deliver balmy temperatures and rain to a big swath of Oregon this weekend, but the Rogue Valley won't get as wet as the coast and points north, forecasters said.

A special weather statement issued by the National Weather Service office in Medford forecasts increasing rain tonight through Saturday, when the warm front sweeps in from the southwest.

The storm will slam into the Oregon Coast on Saturday morning, then slide inland to the northeast.

"It's a bull's-eye for Pacific City and Manzanita," said meteorologist Mike Ottenweller.

About two inches of rain is expected there in the storm, he said. An inch to an inch and a half is forecast for Coos Bay, Roseburg and Brookings, but Medford and Ashland probably will get around a quarter of an inch.

"We're pretty well protected by the mountains," Ottenweller said.

The chance of rain will pick up tonight locally, and Friday will be showery across the region. The current forecast predicts a 100 percent chance of precipitation in Medford on Saturday, probably arriving around 4 a.m.

Snow levels will be around 5,500 feet when the storm arrives and will lift to 9,000 feet or higher. Ottenweller said Southern Oregon's snowpack likely won't get flushed out because relatively little precipitation is expected in the Siskiyous and Cascades.

In Douglas County, on the coast and other areas where heavier rainfall is expected, creek and river levels are expected to rise rapidly, but at this point, flooding isn't likely.
