...Light to moderate snowfall event increasingly likely for Christmas eve and Christmas day across southeast Wyoming and western Nebraska...

For the snowy...Sierra Madre and likely over the northern Laramie range...a long duration heavy snowfall event is looking increasingly likely for Sunday through Tuesday...with possible snowfall amounts over these mountains of 15 to 30 inches in the long duration snowfall event.

For Christmas eve...and Christmas day...the models are now coming into agreement for a possible 12 to 24 hour snowfall event across much of southeast Wyoming and to a lesser extent over western Nebraska.

Over Christmas eve and Christmas day...a well pronounced disturbance aloft will move across our region...with a band of light to moderate snow likely setting up somewhere over southern Wyoming and northern Colorado...although the heaviest snowfall is quite uncertain at this time...six to seven days away.

While uncertainty a week away is still great with model uncertainty...lower elevations could possibly receive 1 to 4 inches of snow...with 5 to 10 inches of snow over the mountains on Christmas eve and Christmas day.

We will continue to monitor the possible snowfall event closely over the mountains Sunday through Tuesday...as well as over much of southeast Wyoming for Christmas eve and Christmas day... so please continue to monitor media sources...including your National Weather Service Cheyenne website...and facebook and twitter pages.
