The Cheyenne Office of the National Weather Service has updated it's forecast for a major winter storm that is expected to blast the area over the next few days.

In a late Sunday afternoon email, the agency included the following:

• A winter storm beginning late Sunday night is set to cause major impacts to portions of southeast Wyoming and western Nebraska due to heavy snow and blowing/drifting snow.
• Widespread 12 to 18 inches of snowfall is likely, with areas near the Pine Ridge receiving 20 to 30 inches.
• Along with the heavy snowfall, strong wind gusts 45 to 55+ mph Tuesday, will cause very hazardous conditions across east central Wyoming and the northern Nebraska panhandle
