Idaho – Light flakes drift through gray skies early, brushing windshields and quiet streets as winter tightens its grip. In Boise, the morning begins cold and damp, and small changes today could carry outsized impacts for drivers and pedestrians.
According to the National Weather Service in Boise, snow is likely early with mostly cloudy skies and lows near 28. Little accumulation is expected, but even a thin coating can slick roads before temperatures rise. Northwest winds stay light, though visibility may briefly drop during steadier bursts.
Conditions improve later today as clouds break. Sunshine pushes highs toward the upper 30s, helping melt leftover snow on sidewalks and side streets. That thaw sets up a familiar January hazard. Once the sun drops, refreezing becomes likely, especially on shaded roads and parking lots. Plan slower travel this evening and watch for black ice.
Friday brings calmer winter weather. Skies turn mostly sunny with highs near 42. Roads should improve during daylight hours, though cold nights persist. Friday night drops into the mid-20s under clear skies, keeping frost and icy patches in play through early morning.
The weekend stays quiet but cold. Saturday and Sunday trend mostly sunny with highs in the low 40s. Nights dip into the mid-20s again, extending the freeze-thaw cycle. Crews may spot-treat problem areas, but drivers should stay alert on neighborhood streets and bridges.
Early next week looks slightly milder, with highs in the low-to-mid 40s continuing. Meteorologists continue monitoring systems across the West that could reintroduce snow chances beyond the weekend.
There is a bright spot. By late January, Boise gains roughly 40 minutes of daylight, easing the long winter stretch. Heading out this morning or later tonight? Tell us how road conditions look in your part of the Treasure Valley.
