Denver, CO – Snow is expected to gradually increase across Colorado’s high country beginning Wednesday, with hazardous mountain travel conditions developing by Wednesday afternoon and continuing into Thursday.
According to the National Weather Service in Denver/Boulder, scattered light snow is expected through Wednesday morning, followed by steadier snowfall developing by Wednesday afternoon. The most significant impacts are forecast north of the Interstate 70 Mountain Corridor, where snow chances and accumulations will be highest.
Mountain passes including Berthoud Pass, Loveland Pass, Rabbit Ears Pass, and Cameron Pass show increasing probabilities of snowfall Wednesday afternoon through early Thursday. Forecast data indicates precipitation chances rising into the 60 to 80 percent range at several higher-elevation locations during peak travel periods.
While snowfall totals will vary by elevation and location, the National Weather Service emphasizes that travel impacts are the primary concern, not just accumulation amounts. Snow-covered roads, reduced visibility, and slick conditions are expected to develop along I-70, US-40, CO-14, and connecting mountain routes, particularly during the late afternoon and evening hours Wednesday.
Snow is forecast to continue at times into Thursday, prolonging hazardous travel conditions for commuters, commercial drivers, and recreation traffic heading into the mountains. Lower elevations and the urban corridor are expected to see minimal impacts compared to higher terrain.
Drivers are urged to plan ahead, monitor road conditions, and be prepared for winter driving conditions if traveling through the mountains. Chain laws or traction requirements may be implemented with little notice as conditions deteriorate.
Ski travelers, delivery drivers, and overnight commuters should allow extra travel time and check updates before departure.
