Oregon wakes to sharp, biting air as frost clings to rooftops, cars, and fields across the southern Willamette Valley. Breath hangs visibly in the still morning, and sidewalks feel stiff underfoot. This is not a typical coastal chill. Winter has real teeth today.
The National Weather Service has issued a Cold Weather Advisory covering Eugene, Portland, and much of northwest Oregon and southwest Washington. Temperatures and wind chills drop into the 15 to 25 degree range, creating a real frostbite risk with prolonged exposure. The advisory remains in effect through noon, when sunshine finally helps temperatures recover.
Early travel feels unforgiving. Cars take longer to warm, and untreated surfaces stay slick where frost lingers. Drivers should allow extra time and watch shaded areas closely. If you’re heading out, gloves and hats matter more than usual this morning.
By late morning, conditions improve slowly. Sunshine lifts highs into the mid-40s around Eugene, though cold air hangs on longer in valleys. The cold relaxes Sunday, but frosty mornings continue. Overnight lows dip back into the 20s, setting up repeated freeze-thaw cycles that can refreeze moisture on roads.
Looking ahead, Monday brings mostly cloudy skies and a noticeable warm-up. Highs climb into the low 50s, easing travel stress and daily routines. Still, Winter remains present at night. Patchy frost returns late Monday and Tuesday mornings before milder air settles in midweek.
Nationally, a powerful Winter storm dominates headlines with snow, ice, and dangerous cold east of the Rockies. The Pacific Northwest avoids snow impacts for now, but this cold snap serves as a reminder. Even without snow, Winter weather can still disrupt lives.
Check on neighbors, keep pets indoors, and limit time outside early today. How cold did it feel when you stepped outside this morning?
