Early Spring Storm System To Impact Central Wyoming

A low pressure system over the central high plains will bring upslope flow and snow or a rain and snow mix across much of central Wyoming today.  Some roads may become slushy and slick in the basins, while mountain passes will likely be snow-covered with limited visibility in snow and blowing snow at times. 

What/When: Snowfall will begin Saturday morning, and continue through late Saturday  evening. Moderate snowfall accumulations are expected above 6000 feet, with increased wind creating blowing snow over mountain passes.

Amounts / Intensity: 

Natrona County: 2-4 inches with higher accumulations possible south of Casper. 4-6 inches possible over Casper Mountain. Areas of northeast wind 10 to 20 mph with gusts to 30 mph.

Johnson County: 1 to 3 inches. North wind 15 to 20 mph with gusts 30 to 35 mph.

Fremont County: 1-3 inches.   4-8 inches over the eastern slopes of the Wind River Mountains, including the South Pass area. Northeast wind 20 to 30 mph causing blowing snow and limited visibility over South Pass.

Absaroka Mountains: 4-8 inches, with the highest accumulations anticipated over the southern half the the mountain range. Blowing snow will be possible with gusty wind expected Saturday afternoon. 

General Impacts:

Blowing snow can create periods of limited visibilities on mountain passes  through the event. 
Those with outdoor recreation plans should monitor current weather conditions. Dress in layers if heading outdoors, and avoid overexertion.
