Oregon – A sharp early chill is gripping Pendleton and the Columbia Basin right now, where frost is forming on roads, rooftops, and fields, creating slick patches and agricultural concerns through the morning hours.
According to the National Weather Service in Pendleton, a Freeze Warning remains in effect until 9 a.m., with temperatures dropping as low as 24°F across eastern Oregon and parts of southeast Washington, including the Yakima and Kittitas valleys . Clear skies and light winds are allowing rapid cooling in low-lying areas.
Across Pendleton, Hermiston, and along I-84, drivers should watch for isolated icy spots on bridges and shaded stretches. While widespread ice is not expected, even brief slick areas can lead to sudden braking issues. Plan extra travel time through mid-morning and use caution on rural roads.
For residents and growers, the freeze poses a serious risk. Frost can damage early crops, vineyards, and sensitive plants. Cover vegetation now and protect exposed pipes to prevent damage.
Conditions improve quickly by midday, with sunshine pushing highs to around 58°F. A rapid warm-up follows into Saturday, reaching near 71°F with partly sunny skies.
By Sunday, temperatures climb further into the mid-70s under mostly cloudy skies, offering a brief stretch of mild spring weather. However, changes are already developing.
By early next week, rain chances return, with showers possible by late Monday night and more widespread precipitation into Tuesday.
