Idaho — A gray, muted dawn settles over Boise as patchy fog clings to the valley floor, softening headlights and turning wet pavement into a reflective haze. The air feels cool and still, carrying that faint late-November sharpness that hints at the winter transition now underway. With Thanksgiving travel ramping up across the region, drivers should plan extra time, especially on I-84 where fog pockets tend to linger and visibility drops quickly.
Showers taper early as clouds thicken again through the morning. Light winds allow fog to redevelop in stubborn patches, particularly near low-lying neighborhoods and open stretches east of the city. This slow clearing may affect mid-morning commuting and early holiday departures, so residents should watch for sudden changes in visibility.
By Friday, conditions improve. Sunshine breaks through and temperatures reach near 50°, giving the Treasure Valley a brief, welcome reset. Saturday stays mostly sunny and mild, ideal for yard cleanup, early decorating, or pre-holiday errands before crowds swell next week. Light winds keep the day pleasant, making it one of the best travel windows of the week.
However, a Winter Tease shows up on extended models for next week. Cooler air works back into Idaho, and a possible rain-to-snow changeover may develop near Tuesday or Wednesday. Any accumulation remains uncertain, but the pattern aligns with emerging national signals suggesting heavier snow bands across parts of the Northwest, Central U.S., and Rockies between November 25 and early December—a key period for Thanksgiving travelers.
For now, Boise enjoys a quieter stretch, but early winter signs are growing harder to ignore.
