If you have hatches, it may be about time to batten them down. The National Weather Service in Cheyenne is projecting at least 8 inches of snow in Albany and Laramie Counties, and up to 16 inches in higher elevations.

The amount of snowfall mixed with 30-50 mph wind gusts is a recipe for closed roads, dangerous conditions, and limited to no visibility.

Snowfall is expected to begin Sunday night, continue all day Monday, and taper off Tuesday morning.
