In addition to the snow, very cold temperatures and blustery north winds will create areas of blowing snow and dangerous windchill temperatures through Thursday.

Maximum wind gusts of 65-80 miles per hour are possible.

The snow and blowing snow will reduce the visibility to less than 1 mile at times.

Just for reference, wind speeds of 74 miles per hour are generally considered to be hurricane-force winds.

Interstate 80 meanwhile was closed between Rawlins and Cheyenne.

Heavy snow and strong winds may be widespread during this time with significant travel impacts.

A Freeze Watch is in effect for most lower elevation areas for Monday night as that cold air settles into the area.

The Cheyenne Office of the National Weather Service says severe thunderstorms featuring up to quarter-size hail and 60 mile-per-hour winds are possible.

We "could even hit record high temperatures in southeastern Wyoming! Sunny to mostly sunny skies are expected throughout the day with this heat.''

The main hazards will be large hail to the size of golfballs and 60+ mph winds, along with frequent lightning.
