Oregon – Frost clings to windshields and breath hangs in the air this morning as temperatures struggle in the mid-20s across eastern Oregon. Roads look dry for now, but conditions are setting up for a slippery change by tonight.
According to the National Weather Service in Pendleton, a weak system moving in later today brings a chance of snow, sleet, and freezing rain late this evening and into early Wednesday. Temperatures hover near freezing overnight, creating a narrow window where light icing could develop before precipitation turns mainly to rain after daybreak.
Pendleton starts the day near 25°F with mist reported early. Afternoon highs reach the upper 30s to near 40°F, still cold enough to allow ice to linger on untreated roads. The highest concern window runs late tonight through early Wednesday morning, especially on bridges, overpasses, and less-traveled routes.
Travelers along Highway 30, Highway 11, and I-84 near Pendleton should remain alert. Even light freezing rain can create sudden slick spots. This is also prime time for flash freezing if moisture refreezes before sunrise. Slow down, increase following distance, and avoid abrupt braking.
By Wednesday afternoon, temperatures climb toward 50°F, helping roads improve quickly. Rain becomes lighter and more scattered through midweek. Thursday and Friday stay milder, with highs in the low 50s and occasional rain showers, keeping pavement damp but ice-free.
Looking ahead, longer-range outlooks suggest temperatures trending above seasonal averages into early February, reducing prolonged winter impacts locally. That said, brief cold snaps like this can still surprise drivers in eastern Oregon valleys.
For now, plan evening travel carefully, allow extra time early Wednesday, and keep an ice scraper handy. Are roads slick yet where you are around Pendleton?
