On Thursday at 11:26 p.m. the National Weather Service issued a special weather statement until Friday at 6 a.m. for Lower Columbia Basin of Oregon and Foothills of the Northern Blue Mountains of Oregon.
“Patches of freezing drizzle are moving through the area, with temperatures currently hovering between 20 and 30 degrees. As a result, light ice accumulation is causing a thin glaze of ice on roadways, particularly on bridges, overpasses, and lightly used corridors. Conditions are expected to persist until 6 a.m. Use caution if traveling,” says the weather service.
