Boise, ID – Damp air and gray skies linger across the Treasure Valley this morning as Idaho edges toward a quieter stretch of weather for the holiday. Early rain chances today and Tuesday could bring slick roads and light showers, but forecasters say the pattern will shift to calmer, colder conditions by midweek.
According to the National Weather Service in Boise, scattered rain showers will taper off late Tuesday as high pressure builds in from the west. Afternoon highs will hover near 48°F, with cooler nighttime lows dipping into the upper 20s to low 30s. While no snow is expected in Boise itself, higher elevations east of the city could see light flurries Tuesday night as a weak cold front slides through the region.
By Wednesday, skies clear out and the air turns crisp — a classic late-fall setup for Thanksgiving gatherings and early morning travelers. Thanksgiving Day will stay partly sunny with highs around 51°F, followed by a mild cooldown heading into Friday. The weekend could bring another round of light rain or snow showers, but travel impacts appear minimal for now.
Residents should still watch for frosty mornings through Saturday as lows flirt with the freezing mark, signaling the first early winter tease of the season.
