Freezing rain may hit region tonight
Sleet and freezing rain are forecast to hit portions of Southern Oregon and Northern California tonight and early Thursday and could lead to "extremely dangerous" travel conditions, according to the National Weather Service.
The weather service has issued a Winter Storm Watch for early this evening through early Thursday because accumulations of sleet and ice could make it dangerous to walk or drive in these areas.
Of particular concern are portions of Siskiyou County and Interstate 5 north of Grenada, as well as the IIlinois Valley area and Highway 199, according to the weather service.
Some of the year's coldest air will sit beneath a warm front passing over the region, according to the weather service. The result will be pockets of rain and sleet for an hour or two, but the ice could remain longer in some areas, the weather service states in its watch report.
The freezing rain, which can coat surfaces with a layer of ice, is created when the warmer precipitation passes through the colder air near the ground. Even small accumulations of ice are considered safety hazards.
