Area Forecast Discussion
National Weather Service Riverton WY
231 AM MDT WED SEP 7 2016

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT

THUNDERSTORMS CONTINUE TO ERUPT OVER EASTERN WYOMING WHERE THE
BEST CAPES ARE. THESE SHOWERS ARE JUST BARELY CLIPPING OUR AREA
FROM EASTERN SWEETWATER COUNTY THROUGH NATRONA AND JOHNSON
COUNTIES. THE SHORTWAVE RESPONSIBLE FOR THESE SHOWERS WILL TAKE
THROUGH 09Z TO CLEAR THE AREA.

THEN THE FLOW BECOMES MORE ZONAL TODAY RESULTING IN STRONGER WEST
WINDS USHERING IN DRIER AIR. THESE SYNOPTIC SCALE WINDS WILL LINE UP
WITH THE TOPOGRAPHY AND RESULT IN ACCELERATED WINDS THROUGH OUR
SOUTHERN WIND CORRIDOR TODAY. THE COMBINATION OF DRY AIR AND
INCREASED WINDS WILL RESULT IN ELEVATED CRITICAL FIRE WEATHER
CONDITIONS. WE ISSUED A FIRE WEATHER WATCH YESTERDAY FOR OUR
SOUTHERN FIRE WEATHER ZONES BECAUSE THIS PARTICULAR EVENT APPEARED
TO BE RIDING THE FENCE BUT IT STILL APPEARS TO BE A SOMEWHAT
BORDERLINE EVENT. WILL GO AHEAD AND NOT ISSUE THE WARNING BUT JUST
PUT IN CRITICAL FIRE WEATHER WORDING IN ALL OF OUR FIRE WEATHER
PRODUCTS THIS MORNING. THURSDAY APPEARS SIMILAR TO TODAY AS FAR AS
RH GOES BUT WINDS WILL BE A BIT STRONGER ALONG WITH SLIGHTLY HIGHER
RH. THESE WINDS WILL INCREASE IN RESPONSE TO AN APPROACHING
SHORTWAVE/COLD FRONT ALONG THE NORTH PACIFIC COAST AND WILL
EVENTUALLY TRACK ACROSS MONTANA AND WYOMING FRIDAY MORNING. MOISTURE
WITH THIS WEATHER FEATURE WILL BE SCANT AND ONLY AFFECT FAR NORTHERN
WY, PROBABLY ONLY GIVING THE FAR NORTHERN MTNS SOME PRECIP, PERHAPS
JUST THE NORTHERN BIG HORNS FOR THURSDAY AFTERNOON, THURSDAY NIGHT,
AND FRIDAY. TEMPERATURES WILL BE 5 TO 10 DEGREES COOLER FRIDAY
BEHIND THE FRONT EXCEPT IN OUR EAST CENTRAL ZONES SUCH AS
CPR/BYG/RIW TEMPERATES WILL BE A GOOD 15 DEGREES COOLER FRIDAY. MUCH
DRIER AIR WILL THEN USHER IN FROM THE WEST FRIDAY NIGHT IN THE WAKE
OF THIS WEATHER SYSTEM.

.LONG TERM...SATURDAY THROUGH WEDNESDAY

The weekend looks dry and warmer with continued fire weather
concerns. Most areas looks breezy to windy and many of the lower
elevations and foothills look very dry, especially the south half.
Thankfully, our weather system for early next week will cool things
off and bring in increasing moisture levels. Overall longwave
pattern shows the mean trough centered near our area now will move
eastward as a strong ridge develops just off the PacNW coast. With
the little further east mean trough axis, it looks like the majority
of the energy will stay off to the north and east early next week.
It will still likely turn cooler and unsettled for a couple days as
the weather system moving just south of the west end of the
Aleutians moves over the developing ridge and then digs into the wrn
Great Basin (or even as far west as nrn CA) and closes off to our
west. A cold Alaska system will likely help with a strong cold
frontal passage Sunday night into Monday morning as it brushes just
off to the northeast. Some energy from our wrn Great Basin upper low
overrunning the cold front will help with the pcpn potential on
Monday into Monday night. Airmass will likely turn more unstable
Tuesday into Wednesday as temperatures start to rebound and cool
upper low to the west provides some cooler mid levels, moisture and
weak forcing. So still probably a decent chance of some light to
locally moderate pcpn Monday turning more showery/tstms, especially
along and west of the divide Tuesday into Wednesday with
temperatures moderating after a much cooler/colder Monday.

&&

.AVIATION.../12Z ISSUANCE/

VFR conditions will prevail through the forecast period. Story
FOR WEDNESDAY will be increasing westerly flow behind the
departing shortwave this morning. Winds will increase at KCPR and
KRKS between 15z-18Z/Wed, and later in the afternoon at KBPI and
KPNA. West-to-northwest flow aloft will favor speeds of 15-25kts
by late afternoon at these terminals. Could also be some 10-20kt
winds at KCOD but confidence is not as high there. Winds will
decrease shortly after 00z/Thu with speeds becoming less than
12kts at each terminal by 02Z/Thu. Conditions will be dry, and
any isolated weak shower would be confined to areas very close to
the Montana border.

&&

.FIRE WEATHER...

WEST FLOW ALOFT WILL INCREASE OVER WESTERN AND CENTRAL WYOMING
with limited MOISTURE. TEMPERATURES WILL GRADUALLY WARM AS THE
flow increases. RELATIVE HUMIDITY WILL BE LOW WITH GUSTY
AFTERNOON and evening WINDS, ESPECIALLY ACROSS THE SOUTH,
INCLUDING FIRE weather zones 277 279 and 289 TODAY AND THURSDAY.
WILL GO AHEAD AND upgrade the FIRE WEATHER WATCH TO A WARNING AS
GUIDANCE HAS BEEN fairly consistent IN ADVERTISING A BORDERLINE
RED FLAG EVENT FOR Fire weather ZONES 277, 279, AND 289. A COLD
FRONT WILL PUSH ACROSS the area THURSDAY NIGHT FOLLOWED BY COOLER
WEATHER FRIDAY, especially east OF THE DIVIDE. THEN A WARM UP
ALONG WITH STRONG DRYING west winds WILL POSE THE GREATEST
WIDESPREAD CRITICAL FIRE weather conditions FOR THE WEEK THIS
WEEKEND. THIS WILL BE FOLLOWED BY a potential COOL WET WEATHER
EVENT EARLY NEXT WEEK. IN FACT, THE RH WILL WASTE NO TIME IN
PLUMMETING TO THE UPPER single digits AS EARLY AS FRIDAY
AFTERNOON BEHIND THE FRONT ACROSS Lincoln and SWEETWATER
COUNTIES.
