The second major storm in as many weeks will begin on Monday, bringing another round of heavy snow to the Rockies and Plains through at least the middle of the week.
Major cities along the Front Range, such as Denver and Fort Collins, will start as rain on Monday. As a steady flow of cold air works in from the north, a change to all snow is expected by late in the day or at night.
Snowfall amounts in Denver are dependent upon how much cold air is in place and how much moisture there will be. At this time however, it looks as if anywhere from 4-8 inches will fall across the metro area with the highest accumulations in the western suburbs and the lowest in the eastern suburbs.
Farther north in Boulder and Fort Collins, rain will change to snow more quickly, and there will be more moisture present to work with. Snowfall accumulations here will range from 6-12 inches.
All snow will fall north and west of Denver along the foothills and in the mountains. This includes places such as Eldorado Springs, Crescent, Wallstreet, Jamestown, Nederland, Ward and Estes Park, to name a few. All snow will also fall farther north into southeastern Wyoming, across cities such as Cheyenne and Laramie.
Snowfall of 12-24 inches is likely across these areas. Blowing and drifting snow could lead to drifts of several feet high along north-facing sides of buildings and out in open areas.
This storm will also impact the plains of eastern Colorado and western Nebraska. Locations from Greeley and Sterling in Colorado northeastward to Scottsbluff and Chadron in Nebraska could have as much as 6-12 inches by Wednesday night.
Major travel disruptions are expected from this storm, especially along important interstates. Snow will fall at close to 2 inches per hour at times, and when combined with wind gusts of 30-40 mph, travel will become very dangerous, if not impossible, along parts of Interstate 80 in southern Wyoming.
Similar dangerous travel is along Interstate 76 in northeastern Colorado and Interstate 25 from Denver to Cheyenne.
Your best course of action will be to avoid traveling during this storm. If travel is absolutely necessary, be sure to have a winter weather survival kit with you in your vehicle.
This kit should include a flashlight, blankets, hand warmers, food and water, flares and a snow shovel.
This will be a long-duration storm with the heaviest snow arriving in several rounds. It will not come to an end until Wednesday night and Thursday.
