.SHORT TERM...(This evening through Friday)
Issued at 200 PM MDT Wed Oct 11 2017

Some high clouds moving across the CWA in southwesterly upper flow.
Should see a decrease in these through this evening as moisture
decreases thus expecting a mostly clear and quiet night.

A shortwave will eject northeast on Thursday from an upper trough
over the northwestern CONUS. It will push a weak cool front across
the CWA during the day and bring some breeziness especially out west
in the afternoon. Dry weather expected until Thursday night when
a few showers may develop over the northern Panhandle area. A better
push of cooler air will then sink down the high plains Friday cooling
max temperatures about 10 degrees or so especially over the Panhandle.

.LONG TERM...(Friday night through Wednesday)
Issued at 200 PM MDT Wed Oct 11 2017

The 12Z medium range model and ensemble consensus progs the next Pacific
upper trough and cold front to bring cooler and showery weather Saturday.
Snow levels lower to 7500 feet Saturday, however snowfall will be light
with up to an inch possible. The flow aloft backs from northwest to
west-southwest early next week with the passage of a low amplitude upper
ridge. Temperatures will moderate from the 40s and 50s Sunday to the
50s and 60s Monday through Wednesday, along with breezy west-southwest
winds each afternoon for much of southeast and south-central WY.
