Oregon – Cold air sits heavy across the Blue Mountain foothills this morning as breath fogs briefly and cars scrape light frost. The ground feels firm, and the chill lingers longer in shaded spots. Winter remains in control early today.

According to the National Weather Service in Pendleton, temperatures hovered near 36 degrees before sunrise with light east winds. Skies stay mostly cloudy today, keeping highs near 52 degrees. While no winter alerts are active, cold morning conditions still affect travel and daily routines.

Drivers should watch for slick patches on bridges and rural roads, especially along Highway 11 and Highway 395 during the early commute. Frost can form quickly where temperatures dip near freezing, even without precipitation.

Sunday follows a similar pattern. Morning lows fall into the low 30s, then rebound into the low 50s under partly sunny skies. The quick temperature swing remains the main winter concern, particularly for early travelers and outdoor workers.

Conditions improve slightly into early next week. Monday and Tuesday bring more sunshine and milder afternoons, with highs climbing into the upper 50s. Nights stay cold, dipping back into the low to mid-30s, allowing frost to redevelop in colder pockets.

By Wednesday, skies turn sunnier, though highs ease back into the low 50s. The dry stretch continues, offering stable travel but persistent cold mornings.

Across the nation, winter storms impact the Great Lakes and Northeast. Locally, Pendleton stays quiet, but winter still demands attention. Flash freezing can occur when frost melts and refreezes near sunrise, especially on untreated roads.

Daylight is slowly improving. By the end of January, Pendleton gains about 40 extra minutes of evening light, helping afternoons warm faster.

Residents should dress in layers, allow extra travel time early, and stay alert for icy spots. How cold did it feel where you started your morning?
