Fort Collins, Colorado – A colder, storm-driven pattern is locking into northern Colorado as December begins, triggering a December Snow Alert while winter in Fort Collins turns more aggressive. While it’s too early to determine exactly how many inches of snow could fall, one thing is certain: Colorado is positioned for an above-average amount, especially along the northern Front Range where upslope patterns frequently amplify snowfall.
According to the Climate Prediction Center, below-normal temperatures and near- to above-normal precipitation are favored across the central Rockies through December. According to the National Weather Service in Boulder, this setup supports multiple early-winter storm windows, including strong upslope systems, clippers, and Arctic fronts that can deliver significant snow to Larimer, Weld, and Boulder counties.
According to CDOT, travel hazards are expected to increase along I-25 from Longmont to Wellington, Highway 287, and I-76 near Greeley as colder mornings allow black ice and bursts of heavy snow to reduce visibility. Mountain corridors west of the metro — including Cameron Pass and Poudre Canyon — may see drifting snow and dangerous wind chills. Drivers should carry winter kits, keep devices charged, and allow extra travel time.
Holiday events across Fort Collins, Greeley, Loveland, and Boulder may face scheduling adjustments if storm systems arrive during evening hours. Residents should dress in layers, protect exposed pipes, and prepare for outages if wetter snow combines with gusty winds along the foothills.
While exact totals remain uncertain this early, long-range trends strongly support a colder, snow-heavy pattern — raising confidence that Northern Colorado is headed for a snowy December and lifting White Christmas prospects across the Front Range.
