Salt Lake City, UT – A powerful Arctic front will push into Utah beginning Saturday, November 30, sending temperatures tumbling and creating hazardous travel conditions through the first week of December.
According to the National Weather Service, a strong Arctic air mass descending from Canada will settle across the Intermountain West, dropping temperatures well below normal. The Climate Prediction Center forecasts a 70–85% chance of below-average temperatures statewide, with overnight lows in the single digits and subzero wind chills possible across northern and central Utah.
Drivers traveling along I-15 and I-80 should prepare for slick highways, blowing snow, and limited visibility—particularly in canyons and higher elevations. The Utah Department of Transportation urges motorists to reduce speeds, check road advisories, and carry emergency kits as Arctic air grips the region.
This cold outbreak marks the strongest of the season so far, signaling a shift to sustained winter weather for Utah and much of the western U.S. The chill will likely persist into mid-December before any major warm-up occurs.
Residents are encouraged to layer clothing, protect plumbing and outdoor pets, and stay alert for wind chill advisories. Snow accumulation may also increase avalanche risks in mountainous terrain.
