Oregon drivers step into a damp, chilly Monday morning as rain taps roofs and clouds sit low over the Blue Mountains. In Pendleton, wet pavement and cool air define the first Monday of 2026, with winter conditions lining up behind today’s rain.
According to the National Weather Service, light rain continues through the morning with temperatures climbing into the upper 40s by afternoon. Winds stay breezy at times, adding a raw feel to the day. Roads across Umatilla County remain slick, especially during school drop-offs and the midday commute.
Conditions shift quickly after sunset. Skies partially clear Monday night, allowing temperatures to fall near 30 degrees. That drop raises concerns for black ice on untreated roads, bridges, and rural highways, including stretches of U.S. Route 30 and nearby county roads. Drivers should slow down and watch shaded areas early Tuesday.
Tuesday brings another round of rain, with highs near 48 degrees. Gusty southwest winds develop, pushing moisture back into the region. By Tuesday night, colder air moves in. Rain becomes more persistent, and temperatures dip into the mid-30s, setting the stage for a rain-to-snow mix.
By Wednesday morning, winter tightens its grip. Light snow may mix in at times, especially during early hours, with snow levels lowering close to valley floors. Accumulation appears limited, but even light snow or slush could impact travel. Keep extra space between vehicles and allow more time.
Thursday continues unsettled with additional rain and snow chances before a gradual improvement late week. Nights stay cold, with lows hovering near freezing.
Meteorologists continue monitoring incoming systems across the Pacific Northwest, meaning winter travel issues could evolve quickly. Commuters should stay weather-aware through midweek.
