A slow-moving winter system is expected to keep snowfall going across the northern and central Rockies on Thursday, with impacts stretching from Montana into Colorado. While the most intense snowfall may occur earlier in the week, lingering snow showers and periods of accumulation remain possible, particularly in higher elevations and along key travel corridors.
Across Montana, snow is expected to continue into Thursday, especially across western and central portions of the state, including areas near Bozeman, Helena, Great Falls, and Butte. Colder air firmly in place will support snow as the dominant precipitation type, with intermittent bursts capable of reducing visibility and creating slick road conditions. Mountain passes may see the greatest impacts as snow persists through the day.
Farther south into Wyoming and Colorado, snow chances are expected to increase or linger Thursday as the system gradually shifts southeast. In Colorado, areas along and west of the Front Range, including Denver, Boulder, Fort Collins, and Colorado Springs, may see periods of snow or snow showers, especially during the morning and midday hours. While snowfall rates may be lighter at times, on-and-off snow could still lead to slushy accumulation on roadways.
The primary concern is prolonged winter travel impacts rather than a single burst of heavy snow. Snow-covered roads, icy patches, and reduced visibility are possible on major routes including I-90 in Montana, I-25 and I-70 in Colorado, and across mountain passes connecting the two states. Gusty winds at times may contribute to blowing snow in open areas.
By Thursday night, snow activity is expected to gradually diminish from north to south, but cold temperatures will allow slick conditions to persist into early Friday. Travelers are urged to plan for winter driving conditions, allow extra time, and monitor updates closely, as small shifts in system strength could extend snow impacts longer than currently expected.
