Historic winter storm to impact Rockies and Plains

Christopher Nunley

A historic winter storm will cripple parts of the Rockies and Plains over the weekend. Some areas will experience feet of snow, which will create significant travel impacts, allow for power outages, as well as damage to trees. A few areas that will see the biggest impacts are Colorado, Wyoming, and parts of Nebraska.

A potent upper-level system is moving over the Southwest. This system will move northeast into the Rockies over the weekend, followed by the Plains early next week. Deep moisture is feeding north ahead of the system, which will contribute to the heavy snow as the moisture is forced up the Front Range of the Rockies.

Current Winter Weather Alerts

A plethora of winter weather alerts have been issued across Colorado, Wyoming, and parts of Nebraska. A blizzard warning is in effect for southeastern Wyoming and the northern Nebraska Panhandle where heavy snow and strong winds will lead to white out conditions. A winter storm warning has been issued for central Colorado, southern & central Wyoming, the southern Nebraska Panhandle, and South Dakota where heavy snow will fall. A winter storm watch has been issued for parts of northwestern Nebraska and southwestern South Dakota for heavy snow potential.
