An Arctic cold front has bellied up to the Rocky Mountains and will keep Casper and locations along and east of the mountains very cold through Saturday.  Periods of snow will be found across the state as well through Sunday.  For tonight and early Saturday the heaviest snow will be in central and southeastern areas.  Three to five inches is possible for southeastern Wyoming with 6 to 12 inches in the southern mountains.   Casper will see two to four inches. 

A break from most of the snow will occur during the day Saturday, but a new round is likely for central, western, southern and eastern Wyoming Saturday night and Sunday!
