...Storm System to Bring Cold Temperatures and Widespread
Precipitation to the Region Wednesday Night Through Friday...

An area of low pressure tracking towards Utah will slow as it
crosses the central Rockies on Thursday and Friday. Precipitation
associated with this system will begin falling across southeast
Wyoming on Wednesday night. Snow-levels will be around 6000 feet,
with snow likely falling in areas along and west of the Laramie
Range. Meanwhile, temperatures will be warm enough for
precipitation to remain mostly rain at elevations below 5500
feet. Temperatures on Thursday and Friday will feel more like
February than May, with highs expected to only reach the 30s and
40s. Precipitation will continue through Friday morning before
coming to an end Friday afternoon.

Confidence is increasing that southeast Wyoming mountains above
7000 feet could receive 6 inches or more of snow from this event,
with possibly a few inches of snow mainly on grassy surfaces at
Cheyenne and Laramie. Meanwhile lower elevations of the southeast
Wyoming and the western Nebraska Panhandle can expect widespread
1 to 2 inches of rainfall.

Those with travel plans between Cheyenne and Rawlins late
Wednesday Night through Friday should check back for the latest
forecast information.
