Area Forecast Discussion
National Weather Service Cheyenne WY
849 PM MDT Thu Oct 20 2016

Issued at 846 PM MDT Thu Oct 20 2016

Increased the winds overnight in the 06-12Z period across the
Arlington/Bordeaux areas as the 850 mb CAG-CPR gradient comes up
to 45 meters. Not expecting high wind highlights at this point,
however a few gusts to 45-50 mph will be possible.


.SHORT TERM...(This evening through Saturday)
Issued at 135 PM MDT Thu Oct 20 2016

Quite mild and dry weather will be over the CWA through Saturday
with only concerns being with fire weather. The next couple days
will see an upper ridge slip east across the region with just some
high clouds spilling over the area. Weak impulses moving over the
northern Rockys will induce some lee troffing which will create
some gusty winds around the southeast Wy mtns mainly in the
afternoons. Sunshine and downslope flow will bring warmer temps
across the CWA Friday with even warmer temps Saturday as 700H
temps rise from around zero C today to about 4-6C Saturday and
near 8C Sunday. Max temps over the Panhandle Sunday look to
reach/exceed 80.

.LONG TERM...(Saturday night through Thursday)
Issued at 135 PM MDT Thu Oct 20 2016

Upper ridging across the central and southern Rockies will keep
most of any shortwave energy north of our area through
Sunday...then as a strong upper low moves into the Pacific
Northwest the upper flow over Wyoming and western Nebraska goes
more west to southwesterly bringing an increase in passing
shortwaves across the region Monday into Tuesday. Ensembles have
increased chances of rain and snow (higher elevations) across
parts of Carbon and Albany counties early in the week. It also
looks to be rather breezy across Carbon and Albany counties Sunday


.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 846 PM MDT Thu Oct 20 2016

Vfr conditions through the taf period. Winds will increase at the
southeast WY sites between 06-12Z with gusts to 20-25 kts through
the early afternoon on Friday. A few high level clouds will pass
over the area from time to time.


Issued at 135 PM MDT Thu Oct 20 2016

Expect to have at least some elevated fire weather concerns the
next couple days as warmer temperatures and increased winds
occur. Most likely area for critical conditions Friday afternoon
out west but fuels are considered non-critical now. Concerns
increase over the plains Saturday but at this time only expecting
marginal conditions for a relatively short time Saturday
afternoon. Conditions then turn a little cooler and more moist
Sunday into early next week lowering concerns.
