Area Forecast Discussion
National Weather Service Riverton WY
255 AM MDT TUE AUG 2 2016

.SHORT TERM...Tuesday through Thursday night

All is quiet at this time across the western and central Wyoming
today. We have three concerns today. One is temperatures. It looks
to be another hot day across the area with high temperatures in the
90s for most of the lower elevations. A few of the warmer areas like
Greybull and Worland could get close to the century mark. We are
going closer to the GFS MOS since it has verified better while most
guidance has been too goo. The second concern is fire weather. For
the most part, winds will not be strong enough for fire weather
highlights. Plus, since Wednesday looks to be more of a concern, we
will not issue anything. A few areas, like the Absarokas could get
close. A place like Buffalo could get the wind, but relative
humidity may not reach critical levels. We will highlight near
critical conditions in the fire weather products. The third concern
is for the potential for thunderstorms. Both the NAM and GFS have
some convection moving across the area with a passage of a
shortwave. Coverage will be sparse and most areas will not see one,
but many areas will have a chance in the afternoon and evening. And
again, if I had a dollar for every time I said this the past month I
would be a rich man, the main threat will be downburst wind with the
large temperature / dew point spreads.

On Wednesday a cold front will sweep across the area from northwest
to southeast. This presents a few problems. One is for high
temperatures, depending on the timing of the front. For now, we have
gone with the warmer solution. These may have to be adjusted though.
As for thunderstorms, both the models are fairly dry with most
activity in then east. As a result, we left continuity alone for the
most part.

The biggest threat on Wednesday is critical fire weather. The front
sweeping southward across the area will tighten the pressure
gradient ahead of it. This will increase southwest flow ahead of the
front and increase wind for places like Casper. And behind the
front, cold advection behind the front will increase winds in places
like the Wind River Basin and Big Horn Basin. Winds look to be at
least breezy if not windy in many locations. In addition, some very
dry air will move in. If the GFS is correct, a place like Riverton
could have a temperature / dewpoint spread as large as 77 degrees.
Nevertheless, fire weather highlights look like a near certainty for
much of the area.

And for those of you that are tired of the hot weather, you will
like Thursday. A cooler, more stable air mass will move in and bring
some nice weather. High temperatures will be around 10 degrees
cooler than on Wednesday. This day will also feature lighter winds
along with somewhat higher humidity that will dial down fire danger
as well.

.LONG TERM...Friday through Tuesday

A couple of disturbances in the southwest flow on Friday in
combination with some monsoonal moisture pulling northward will be
enough for isolated to perhaps locally scattered convection.
Models have been consistent with one wave pushing across the
extreme NW WY while the other pulls across SE WY Friday. The
forecast area is on the anti-cyclonic side of the upper jet and
instability is expected to be quite limited which should help keep
the coverage of the convection limited. On Saturday, models show
enough moisture and instability for isolated convection, but do
not show any distinct wave in the flow at this time.

A shortwave trough pushing around an upper low near Vancouver will
push across the Intermountain West/Northern Rockies of
Idaho/Montana in the Saturday night/Sunday time frame. The GFS and
GEM remain much drier than the ECMWF as they both dry slot much of the
area and suppress the monsoonal moisture to the far
south/southeast sections of the forecast area. Will continue with
mountain PoPs with an emphasis across the NW closer to the wave.

The upper low over Vancouver on Sunday is expected to push slowly
east along the Canadian/U.S. Border Monday and Tuesday reaching
the Saskatchewan/Montana Border late Tuesday. This should keep a
mainly dry southwest flow over the region with fire weather
concerns being the main concern.

.AVIATION.../12Z ISSUANCE/

West of the Continental Divide...KJAC/KBPI/KPNA/KRKS

VFR conditions will prevail through tonight. Isolated showers and
thunderstorms will develop after 19z and continue through 02z.
Gusty wind to 35 knots will be likely near storms or showers.
Some mountain obscuration will remain possible as smoke from
nearby wildfires continue.

East of the Continental Divide...KCOD/KCPR/KLND/KRIW/KWRL

VFR conditions will prevail through tonight. Isolated showers or
storms will occur after 21z through 03z. A gusty wind to 35 knots
will be likely near storms or showers. Will not put VCTS at the
terminal sites at this time due to the very isolated activity.

&&

.FIRE WEATHER...

...NEAR CRITICAL FIRE CONDITIONS FOR PORTIONS OF WESTERN MOUNTAINS...

An upper level disturbance will cross the area today and bring
isolated thunderstorms in the afternoon and evening that could have
erratic wind gusts. This disturbance will also bring breezy
conditions to portions of the western mountains. Although critical
fire danger is not expected at this time, fire danger could be
elevated for a time this afternoon. Mixing and smoke dispersal will
be fair to good east of the Divide and good to very good west of the
Divide.
