The National Weather Service said a long swath of Oregon and Washington, including the greater Vancouver area, may experience patchy, light freezing rain Friday morning.
There is a small window of possibility for the forecasted freezing rain in the area. The rainfall will create little, if any, ice accumulation on the roads from 8 to 10 a.m. for the Willamette Valley and Clark County, according to the weather service.
The threat may last until 1 p.m. for valleys in the south Washington Cascades, far north Oregon Cascades and Upper Hood River Valley, according to the weather service.
At 3 a.m. Friday, temperatures in many lowland areas were in the upper 20s to lower 30s.
