The outlook for the latter half of June is leaning toward Wyoming being between a ridge along the west coast and a trough along the Mississippi Valley. This currently brings a higher chance for above normal temperatures, especially to the west. This will also keep Wyoming in a more active pattern, with more likely chances for precipitation.

After a warm and sunny Friday, the arrival of a cold front Friday night will make for a cloudy and cool Saturday and Saturday night across areas east of the Continental Divide. Temperatures will be significantly cooler in this region, and a gusty northerly wind will make for a "chilly" summer day. Heading to the Bighorns? Prepare for some light snow or rain depending upon elevation. Western areas will be seasonal under a mostly sunny sky through Saturday.
