Area Forecast Discussion
National Weather Service Cheyenne WY
1029 PM MDT Mon Oct 24 2016

.SHORT TERM...(This evening through Wednesday night)
Issued at 158 PM MDT Mon Oct 24 2016

High clouds streaming across the CWA in southwesterly upper flow
ahead of a large upper trof off the west coast. A shortwave
ejecting ahead of this trough will cross the central Rockys later
tonight into Tuesday and is expected to bring widely scattered
showers to mainly western parts of the CWA during that time. Any
snow will be confined to the highest mtn tops with lack of any
real cold air. Upper ridging returns to the region Wednesday in
the wake of the shortwave. A weak cool front will push across the
CWA Tuesday night bringing some minor cooling for Wednesday but
temperatures still holding above seasonal norms.

.LONG TERM...(Thursday through Monday)
Issued at 158 PM MDT Mon Oct 24 2016

No major concerns with portion of the forecast package.

Confidence is high that temperatures will remain above normal
through the remainder of the week and this weekend, due to the
influence of the upper level ridge over the Rockies. The only
question is the timing of the shortwave moving through the region
on Friday or Saturday. The GFS is starting to blend with the
Ensembles and the ECMWF solution in bringing the shortwave
through Friday night into Saturday. Precipitation chances will be
rather limited due to very meager moisture profiles. However, we
still cannot rule out the potential for windy conditions on Friday
night into Saturday especially over the wind prone areas. We may
also receive a slight cool down on Saturday. Otherwise, the next
shortwave could impact the area on Monday-Monday night.


.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 1028 PM MDT Mon Oct 24 2016

VFR conditions with broken mid and high clouds over the area over
the next 24 hours. Weak showers out near KRWL will continue
overnight with the Panhandle and areas east of the Laramie Range
dry. Winds picking up again after 15Z through 00Z.


Issued at 158 PM MDT Mon Oct 24 2016

Fire weather concerns look to remain low for most of the week with
min rhs sufficiently high and winds modest for the most part. Some
elevated concerns possible Thursday afternoon as min RHs get close
to 15 percent just east of the mtns and winds become gusty.
