Denver, CO – A weak but moisture-bearing system will bring periods of light mountain snow to northern and central Colorado late Sunday through Monday, creating minor travel impacts for elevations above 9,000 feet.
According to the National Weather Service in Denver/Boulder, snow is expected to begin Sunday evening and continue into Monday morning, with the heaviest accumulation focused along the higher peaks and passes of the Front Range, Summit County, Rocky Mountain National Park, and portions of the I-70 corridor. While snow totals remain on the lighter side, slick and slushy roads are likely in the high country, especially overnight.
Travelers crossing high mountain passes—including Berthoud Pass, Loveland Pass, Rabbit Ears Pass, and areas near Vail Pass—should be prepared for winter driving conditions Sunday night. Temperatures at elevation will support roadway accumulation, even as lower valleys and foothills see primarily rain showers. The NWS encourages drivers to check cotrip.org for chain laws, travel cameras, and updated road closures.
Meanwhile, communities along the foothills and northern plains—including Boulder, Fort Collins, Greeley, Longmont, and Brighton—may see light rain showers through Monday as the system passes. Snow is not expected to accumulate in these lower-elevation locations, but brief heavier bursts could occur along higher foothills.
Forecasters say confidence is high in the timing of the storm, though snowfall totals vary depending on elevation and localized bands. Mountain areas could receive from a dusting to several inches, while lower elevations remain mostly wet.
Drivers heading toward the mountains late Sunday or early Monday should allow extra time and prepare for rapidly changing conditions.
