Area Forecast Discussion
National Weather Service Cheyenne WY
1140 PM MDT Fri Oct 14 2016

.UPDATE...
Issued at 725 PM MDT Fri Oct 14 2016

Sent a quick update to cancel the High Wind Warning for western
and northern Carbon county as winds have lowered below 40 MPH and
are expected to stay there through the night. Kept the warning
out for east-central Carbon county including the Arlington area
for the rest of the night since several models do show the llvl
gradient increasing over this area after midnight...so can not
rule out gusts between 50 to 60 MPH due to gap winds.

&&

.SHORT TERM...(This evening through Sunday)
Issued at 401 PM MDT Fri Oct 14 2016

Widespread dry and windy conditions have been observed today over
much of the forecast area, so the Red Flag Warning remains in
effect through early this evening. Regarding the High Wind
Warning, a few sites along the I-80 corridor out near Arlington
have reached or surpassed warning threshold, with a couple others
in central and northern Carbon County quite close in the low to
mid 50mph range. Will leave the warning as is for now, but
wouldn't be surprise to  see locations other than Arlington see
winds come down early. A brief break in the winds is anticipated
for the Arlington area later this evening, but strong winds look
to return around midnight with 700mb winds progged to range 50-55
kts with an inversion just above mountain top. So extended the
Warning for the North Snowy Range Foothills (which includes the
I-80 corridor near Arlington) through early Saturday morning.
Will have to keep an eye on the I-80 Summit as well, but models
do not fully support high winds potential here. It will still be
windy, but thinking gusts will only be in 45-50 mph range.

The shortwave trough causing the strong winds today will quickly
move to the northeast late tonight and tomorrow. The llvl gradient
will weaken as a result, so winds overall will be weaker. In
addition, moisture advection from the west and cooler temps
will keep humidities overall higher in the upper teens to low
20s. Therefore, fire weather concerns will be less than today,
but still elevated. A few rain/snow showers still look possible
over the high mountains and vicinity tomorrow morning with
increasing moisture, but no impacts are expected.

Late Sunday morning and afternoon will likely bring return of
high winds as the next shortwave trough moves over the northern
Rockies. Gradient and wind progs are more favorable for high
winds than with the current system, so will have to contemplate
wind highlights along and west of the Laramie Range over the next
couple forecast cycles.

.LONG TERM...(Sunday night through Friday)
Issued at 401 PM MDT Fri Oct 14 2016

Forecast challenges will focus on high wind potential early in the
period, then precipitation and cooler temperatures mid-week. Leading
edge of 120kt west-southwesterly upper jet moves from northern CA
across NV, UT and into WY Monday. Strong cross barrier flow/mountain
wave sets up late Sunday night through Monday. High winds are
certainly a good bet for the Arlington, Bordeaux and Vedauwoo areas
during this time and headlines will likely be issued as we draw
closer to the event. Monday will be another mild day with highs in
the 60s and 70s east of the Laramie Range and 50s west. Moisture
will spread into southern WY Monday with rain showers developing
along and west of the Laramie Range through the afternoon. A Pacific
cold front is progged to move through the CWA Monday night with
relaxing pressure gradient and diminishing winds. Mountain showers
will end Monday night with the departure of one shortwave trough.
Per the ECMWF, a deeper shortwave trough will track east across
WY/CO Tuesday night and Wednesday with fairly widespread rain/snow
showers. Conversely, the GFS forms a cutoff low over central WY
midday Wednesday and settles south into CO/NM through Thursday.
This scenario would prove to be cold and wet for CWA. Not buying
the GFS solution and will lean closer to the ECMWF with showers
ending Wednesday night. Expect temperatures trending cooler than
normal Tuesday and Wednesday. A sprawling upper ridge amplifies
over the western CONUS Thursday and Friday, with temperatures
moderating to above normal and dry conditions resuming.

&&

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1138 PM MDT Fri Oct 14 2016

Southwest winds will remain breezy at RWL through around 10Z with
gusts to 20-30 kts. Winds will increase once again by late morning
across southeast WY with gusts to 20-30 kts. Mid to high level
clouds will pass over the area throughout the taf period.

&&

.FIRE WEATHER...
Issued at 601 PM MDT Fri Oct 14 2016

Critical fire weather conditions will ease somewhat this evening.
Windy conditions will prevail tonight over portions of Albany and
Carbon Counties, with humidities not expected to recover a whole lot
from today. Increasing moisture and cooler temps tomorrow, along with
weaker winds, should keep critical conditions at bay. However, should
still expect elevated fire concerns through Saturday afternoon. A
return of strong winds on Sunday could bring critical conditions
to the plains in the afternoon.
