SPOKANE, WA — Gray skies and patchy freezing fog blanket Spokane early this morning, a typical late-November chill that settles low in the valley. Car roofs glisten with frost, and visibility drops below a mile in some areas. Drivers along I-90 should use caution during the early morning hours — slick spots and limited visibility are possible through midmorning.

The calm start won’t last long. A moist Pacific front approaches the Inland Northwest, spreading light rain Sunday that could briefly mix with snow as temperatures hover near freezing. This isn’t Spokane’s first brush with snow this season, but it’s another reminder that winter travel hazards are gradually returning. By Sunday evening, a cold rain settles in, with minor slushy accumulation possible on grassy surfaces north of town before temperatures edge above freezing.

Monday brings a clearer, brighter break under partly sunny skies and highs in the mid-40s — a short reprieve before another unsettled stretch midweek. For Thanksgiving travelers, local roads should stay mostly dry through midweek, but national weather patterns tell a different story. A major cold front forming across the central U.S. could unleash heavy snow and air travel delays from the Rockies to the Northeast just as millions take to the skies and highways.
