A large trough of low pressure will be settled over the Pacific Ocean and western parts of the nation for the rest of today, Wednesday, and Thursday.  This will funnel subtropical moisture and atmospheric instability into the state of Wyoming during this time.  However, there is not as much moisture associated with this weather system compared to the one last week.  Expect early sunshine during this time and then clouds will thicken for the afternoon and evening hours.  There will also be a chance for isolated to scattered showers and thunderstorms.  Any storms that develop could be capable of producing strong winds, lots of lightning, and small hail.  Temperatures will remain mild and close to average through at least Thursday.  Daytime highs will be in the 50's and 60's, with some lower 70's in the far eastern Plains.  The large weather system that has been settled over the west coast will slowly propagate east on Friday and Saturday, which will create a better chance for showers and thunderstorms.
