Idaho – Headlights glow against low clouds this morning as damp air settles into the Treasure Valley. Light snow showers drift through early, softening road edges and creating slick patches before daylight gains strength.
According to the National Weather Service in Boise, snow showers are likely through late morning, with total accumulation staying under half an inch. Patchy fog develops at times, especially during the morning hours and again late at night, reducing visibility and increasing the risk of icy travel.
Across Boise and nearby communities like Meridian, Eagle, and Kuna, commuters should plan extra time early today. Wet pavement can refreeze quickly where temperatures hover near freezing. Bridges, overpasses, and shaded streets are most vulnerable. Slow down along I-84, surface streets, and neighborhood roads where visibility may drop suddenly in fog.
Conditions stabilize heading into Thursday, though clouds remain stubborn. Highs reach the low 40s, offering modest relief but keeping roads damp. Fog becomes the primary concern Thursday night into Friday morning, when temperatures dip back below freezing. Drivers should expect pockets of slick travel during early commutes.
A noticeable shift arrives by the weekend. Friday stays mostly cloudy with highs near the low 40s, but Saturday pushes toward the upper 40s, signaling a gradual winter break. Sunday looks even milder, with highs near 50 degrees under mostly cloudy skies. Snow is not expected during this stretch, improving overall travel conditions.
The broader western pattern favors drier weather into early February. NOAA’s 6–10 day outlook points to near- to below-normal precipitation across Idaho, while warmer-than-average air spreads east across the country.
For now, timing matters most. Watch for snow and fog early today, then refreezing late at night. How are conditions where you’re driving this morning?
