Freezing rain might pelt Medford, Ashland and other chilly areas in the Rogue Valley Thursday evening, the National Weather Service reports.
"We have cold air that is trapped in the valley and we're not sure when that's going to clear," meteorologist Misty Duncan said, explaining that there is a layer of warm air above that. "If the rain falls through the warm air and then through the cold air, it's likely to freeze."
The weather service station in Medford is calling for a 70 percent chance of freezing rain to fall between 4 p.m. and 10 p.m., Thursday, but there should be little ice accumulation, Duncan said.
After 10 p.m., Thursday, the temperature should climb above freezing as the valley's blanket of cold air disperses. Then, the freezing rain will turn to water, Duncan said.
"Expect any areas that are still snow-covered and still in the shade ... any areas that haven't been in the sun for the last few days will probably have ice accumulation," Duncan said. "It's kind of just concentrated in the valleys where the cold air is still stuck."
The weather service is also calling for freezing fog across the Rogue Valley from 10 tonight until 1 p.m. Thursday.
Friday's forecast calls for a 20 percent chance of rain before 10 p.m., after which a high of 46 is expected as the sun begins to shine through lingering clouds.
