Area Forecast Discussion
National Weather Service Cheyenne WY
1030 PM MST Thu Feb 1 2018
.SHORT TERM...(This evening through Friday night)
Issued at 248 PM MST Thu Feb 1 2018
Main concerns through Friday will be with winds in the wind prone
areas, then with increasing snow over the higher mtns. Gradient
fcst to increase out west overnight and it appears it will be
enough to bring winds at least close to high wind levels around
the Arlington area. 700H winds come up to near 50kts and decent
downward motion should allow these winds to get strong in that
area so have opted to upgrade the watch to a warning for later
this evening through Friday. The other wind prone areas should
see increasing winds but am not confident that high winds will
materialize there but evening shift will have to monitor.
Otherwise chilly overnight with varying amounts of mainly high
cloudiness advecting over the area from the northwest with some
mtn snow showers. Warmer Friday as the cold surface airmass banked
up against the mtns erodes east and warmer downslope flow ensues.
.LONG TERM...(Saturday through Thursday)
Issued at 248 PM MST Thu Feb 1 2018
Somewhat active in the Saturday through Monday time period as
several disturbances pass across in the northwesterly upper flow.
This time looks to be characterized by some wind events in the
wind prone areas especially late Saturday into early Monday while
a cold front backs in and out against the mtns. Best chances for
widespread snow look to be Sunday and again later Monday as a
couple stronger impulses pass across. In the meantime moist
northwesterly flow will keep snow showers going over the higher
mtns through Sunday, varying in intensity as moisture varies.
Given this rather long period of snow have posted a winter storm
watch for the higher mtns for later Friday night into Sunday as
over a foot of snow looks a decent bet. A milder and drier pattern
then should set in by midweek.

.AVIATION...(For the 06Z TAFS through 06Z Friday night)

.FIRE WEATHER...
