Idaho starts the day under a quiet winter sky, where cold air hangs low over Boise and breath turns visible at sunrise. Pavement feels stiff and dry for now, but temperatures hovering near freezing keep early commuters alert.
A Weather Alert mindset remains appropriate across the Treasure Valley this morning as lows sit in the low 30s. While skies stay mostly clear, cold ground temperatures can still create slick patches on bridges and shaded roads. Drivers heading out before midmorning should slow down and watch for isolated icy spots.
According to National Weather Service data from Boise Airport, temperatures rebound quickly today. Highs climb into the mid-50s with light winds, easing winter’s grip by afternoon. The calmer pattern reduces immediate hazards, but cold nights continue to matter.
Tonight cools back near the freezing mark. That cooling cycle keeps refreeze potential in play where moisture lingers. Even without precipitation, winter driving habits still apply after dark and before sunrise.
Monday brings a steadier feel. Sunshine dominates, winds stay light, and highs reach the low 50s. The pattern turns more stable, helping roads fully dry during the day. Tuesday builds on that trend, with highs near 50 again and clearer skies offering a welcome February break.
By midweek, Boise sees consistent sunshine and daytime temperatures in the low to mid-50s. Nights remain cold, dipping into the low 30s, a reminder that winter is not finished. To be fair, this stretch is calmer than recent cold snaps gripping much of the country.
Meteorologists continue tracking broader winter patterns across the West and Plains. For now, Boise benefits from a quieter window through the first week of February.
Plan morning travel carefully, dress in layers, and keep an eye on shaded streets during colder hours.
