Idaho wakes to a wintry mix this morning as light snow drifts across the Boise Valley, coating cars, rooftops, and quiet streets in a thin, icy crust. The air feels damp and raw, visibility patchy under thick fog. For many residents returning from Thanksgiving travel, the weather brings a full reminder that winter has arrived — and it’s not planning to leave soon.
According to the National Weather Service in Boise, light snow will continue early Sunday with up to a half-inch accumulation possible, mainly before 8 a.m. Roads could become slick where melting and refreezing occur, especially on bridges and shaded stretches of I-84. Drivers should slow down and allow extra space — fog and wet pavement will persist through midmorning before skies clear.
By Monday, high pressure returns, pushing temperatures into the low 40s with mostly sunny skies. But don’t get too comfortable: a weak system Tuesday could bring another 30% chance of rain and snow, followed by patchy fog Tuesday night. That mix of moisture and chill could again cause early-morning slick spots and low visibility — a hallmark of early December in southern Idaho.
Looking toward midweek, conditions turn calmer but stay seasonably cool, with highs near 40°F through Friday. Another weak disturbance may pass by next weekend, but models currently show limited moisture. Still, with freezing mornings ahead, flash-freeze risks remain high for those traveling or commuting before sunrise.
