Impacts in the Denver region are expected to start late in the evening on Monday, Dec. 12, and continue into Tuesday morning, with two to three inches of snow in the metro area and up to four inches in the northern region of Denver.
Pavement conditions will be slick as temperatures fall through the night. Heavy snow is predicted for the Plains east of Denver through Tuesday evening, with blizzard conditions expected.
Crews first make continuous plow passes on the most heavily traveled state-maintained routes, including I-25, I-70, I-76, I-270, I-225, C-470, and other major highways. Then, once the storm subsides, crews will plow different state routes.
CDOT will be in a complete snow shift on the I-70 Mountain Corridor from Golden to the Eisenhower-Johnson Memorial Tunnel. Snow is likely this afternoon and evening, with some blowing snow and heavy snowfalls at times. Poor visibility is expected after midnight, with windchills five to fifteen degrees below zero.
Snow, blowing snow, and poor visibility are expected to continue through Tuesday night.
Snow shifts begin this afternoon and evening in El Paso County and the Pueblo, Trinidad, and South Park areas. Primary areas are expected to be impacted by U.S. 160/La Veta Pass and I-25/Raton Pass. Monument Hill is expecting minimal amounts of snow.
The Arkansas Valley remains on standby if the storm tracks to Southeast Colorado.
Blizzard conditions are expected in areas east of Greeley and along the eastern plains of northwest Colorado on Tuesday morning.
Strong winds gusting up to 60 mph will produce blowing and drifting snow even after the snow ends, leading to possible extended road closures into Wednesday and possibly even Thursday in rural areas as the wind continues.
CDOT works with partners in Wyoming, Nebraska, and Kansas to coordinate possible closures. This means even if Colorado highways are OK, roads may be closed for travel into other states because of conditions there.
Southwest & South-Central Colorado
Heavy snow accumulations are expected for the mountain ranges of southwest and south-central Colorado through Wednesday.
Travel is expected to be difficult with blowing snow and low visibility. Freezing temperatures will also create icy, slick road conditions. Once the storm has cleared, can expect, periodic road closures can be expected on mountain passes to allow for avalanche mitigation operations, possibly through Thursday.
I-70 Mountain Corridor and Northwest Colorado
Snow is expected along the I-70 Mountain Corridor, with higher totals starting at the Eisenhower Johnson Memorial Tunnel and moving east. Further N.W., U.S. Highway 40 will receive much higher snow totals, with more than 20 inches possible through Thursday for Rabbit Ears Pass.
Heavy snow is expected along U.S. 40 near Craig, CO 139 Douglas Pass, CO 65 Grand Mesa, CO 133 McClure Pass, and CO 82 near Aspen. Motorists should plan for winter driving conditions, including blowing snow, low visibility, and low temperatures.
