.SHORT TERM...(Tonight - Saturday)
Issued at 248 PM MDT Thu Oct 12 2017

A cool front is progressing slowly east across the plains this
afternoon but little weather associated with it other than a band
of high clouds. Should see some increase in clouds over mainly
east-central Wy into the Panhandle this evening. Some mid level
instability could still squeeze out a few light showers over the
northern Panhandle later this evening but little if any pcpn seems
likely.

Dry and mild conditions across the CWA Friday with a surface front
lying against the mtns. Cooler over the plains with some breezy
afternoon winds out west. An upper trough over the Pacific
northwest will move east through Friday night and should reach
western Wy by early Saturday. This wil push a stronger cold front
across the CWA late Friday night and Saturday morning with widely
scattered post-frontal showers mainly over western and northern
parts of the CWA Saturday. An inch or two of snow may fall over
the highest peaks.

.LONG TERM...(Saturday night - Thursday)
Issued at 248 PM MDT Thu Oct 12 2017

A quiet weather pattern will prevail through the extended forecast
period. Medium-range models are in fairly good agreement w/broad &
flat upper-level ridging in place over the central Rockies through
mid next week, giving way to dry northwest flow aloft over the CWA
through Wednesday. Daytime high temperatures should be near normal
values for mid October, with no chances for precipitation.
