Boise, Idaho – A more active late-winter pattern is lining up for Idaho in the Feb. 21–27 window, with precipitation odds climbing to 60% to 70% and temperatures easing back toward seasonal norms statewide.
According to the National Weather Service Climate Prediction Center, Idaho falls within a near-normal temperature zone for the 8- to 14-day outlook, meaning highs and overnight lows should track close to late-February averages. While no prolonged Arctic surge is indicated, colder nighttime readings will support snow potential, especially in higher elevations.
Precipitation probabilities are significantly elevated, with a 60% to 70% chance of above-normal moisture. For the central mountains, including Stanley and McCall, that favors accumulating snow with passing systems. In eastern Idaho, communities such as Idaho Falls and Pocatello could see steady snow if colder air holds in place. Across the Treasure Valley, including Boise and Nampa, rain or a rain-snow mix is possible during the day, with snow more likely overnight if temperatures dip below freezing.
Drivers should prepare for slick conditions on Interstate 84 and U.S. Highway 95 during early morning hours. Mountain passes, including Lookout and Galena summits, could see reduced visibility and snow-covered roads during active periods.
The broader pattern supports multiple systems moving through rather than a dry stretch. Additional updates from the National Weather Service may refine timing and potential snowfall totals as late February approaches.
