Sounds like it’ll be a helluva good storm!

An unseasonably cold weather system will swing southeast from
British Columbia toward Wyoming at the end of this week. A
moisture laden stream of Pacific moisture will feed this storm
system which may result in very abundant snowfall amounts for the
mountains of Western and Central Wyoming from late Thursday night
through Saturday morning.
