The second major storm in 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 in Colorado, such as Denver and Colorado Springs, will start as a bit of rain on Monday. As a steady flow of cold air works in, a change to all snow will take place from north to south in the region.
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 a half a foot of snow 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, as well as Cheyenne, Wyo., rain will change to snow more quickly, and there will be more moisture present to work with. Snowfall accumulations in these areas are expected to range between 1 and 2 feet.
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 Casper and Laramie.
A foot or two of snow 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 easily have a foot of snow 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.
If you must travel, 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 snow of varying intensity that will not come to an end until Wednesday night and Thursday.
