Cheyenne National Weather Service

This is a very strong weather system that has the potential to cause major impacts for early September in localized areas

An early winter storm has Wyoming in its sights and there's a possibility of four inches of snow in many areas Monday night into Tuesday

The agency says "hail, some large, and strong wind gusts will likely accompany stronger storms.''

40 - 60 mph wind gusts, pea to quarter-sized hail and brief heavy rainfall will be possible in the strongest of storms.

REMEMBER: A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area.

Tennis-ball size hail and winds of up to 65 MPH are the main hazards expected with these storms.

The agency says ''It will generally be cool and unsettled through the week as several areas of disturbed weather push through the area.''

Cheyenne and Laramie are currently not under any advisories or warnings, but that could change.
