Boise, ID – A cold front moving into Idaho late Sunday and early Monday will bring a mix of gusty winds, light mountain snow, and scattered showers across Southwest and Central Idaho, according to the National Weather Service in Boise. Forecasters say the strongest impacts will arrive Monday morning, especially in higher elevations and the Magic Valley.
According to the National Weather Service, snow totals will remain light, generally 1–2 inches above 5,000 feet, with ski areas such as Brundage, Tamarack, and Banner Summit expected to see the highest accumulations. Lower valleys including Boise, Nampa, Caldwell, Ontario, and Mountain Home are not expected to see measurable snow.
Wind will be the biggest impact for most residents. Peak gusts Monday are forecast to reach 20–30 mph across the Treasure Valley and into Eastern Oregon, while the Magic Valley may see stronger gusts between 30–40 mph, especially around Twin Falls, Jerome, and Burley. These winds may create areas of blowing dust and reduced visibility in open terrain.
Precipitation chances increase late Sunday into Sunday night. McCall, Banner Summit, and the West Central Mountains show the highest probabilities, with 75–80% chances of snow Sunday evening before tapering off into Monday. Boise and the Treasure Valley maintain only slight chances, mostly 5–15% in scattered pockets.
Travel impacts should remain minor, but drivers heading through mountain passes like Idaho City, Mores Creek Summit, Stanley, and McCall may see slick conditions early Monday. NWS Boise advises anyone traveling into higher terrain to watch for brief bursts of snow and rapidly changing weather.
