AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
324 PM MST SAT DEC 27 2008

.SHORT TERM...TONIGHT THROUGH TUESDAY
MODELS REMAIN IN FAIRLY GOOD AGREEMENT ON ACTIVE WX PATTERN ACROSS
WYOMING. SHORTWAVE RIDGING ALOFT TO BE REPLACED BY MOIST ZONAL
FLOW ON SUNDAY. THIS MOISTURE IN THE STRONG ZONAL FLOW WILL
RESULT IN PLENTY OF SNOW IN THE WESTERN MOUNTAINS AND INCREASE IN
SFC WINDS ACROSS MOST LOWER ELEVATIONS EAST OF THE DIVIDE.

FIRST...WEST OF THE DIVIDE. THIS AREA WILL BE AIDED BY GOOD
ISENTROPIC LIFT AND DEEP MOISTURE. HAVE TO BELIEVE SNOWFALL WILL
BE CONTINUOUS IN THE WESTERN MOUNTAINS AND MOST OF YELLOWSTONE
NATL PARK SUNDAY INTO MONDAY AND POSSIBLY TUESDAY. MODELS SHOW
GENEROUS QPF OVER THIS REGION...INCLUDING THE WESTERN VALLEYS. HARD
TO NAIL DOWN SNOW AMOUNTS AT THIS TIME...BUT WILL LIKELY REACH
WARNING CRITERIA FROM THE TETONS TO PARTS OF SALT AND WIND RIVER RANGES.
THEREFORE...WILL ISSUE WINTER STORM WATCH FOR MOST OF WESTERN WYOMING
BEGINNING SUNDAY AFTERNOON. ISENTROPIC LIFT SHOULD WEAKEN BY LATE MONDAY
ACROSS WESTERN WY.

AT THE SAME TIME...A VERY SUBSTANTIAL WIND EVENT LOOKS TO BE
DEVELOPING IN THE FAVORABLE WIND PRONE AREAS OF THE RIVERTON CWA.
A PRONOUNCED UPPER LEVEL JET WILL PUT MOST OF NORTHERN AND CENTRAL
WY IN FAVORABLE HIGH WIND SCENARIO...ALTHOUGH STRONGEST WINDS
LOOK TO MIX DOWN SUNDAY NIGHT AND MONDAY. HOWEVER...GOOD DOWNWARD
FORCING BEGINS DURING THE DAY SUNDAY AS REGION IS UNDER INFLUENCE
OF RIGHT FRONT QUADRANT OF H3 JET. THIS IS WHEN 110-120KT JET
NOSES INTO NORTHERN WY. H7 WINDS ARE EVEN MORE IMPRESSIVE BY
EARLY MONDAY...SPCLY FROM THE MONTANA/WYOMING BORDER TO THE CODY
FOOTHILLS. IN FACT...WILL UPGRADE HIGH WIND WATCH TO HIGH WIND
WARNING FOR ABSAROKAS AND CODY FOOTHILLS BEGINNING THIS EVENING.
CURRENT OBS AND WIND PROFILE WILL KEEP WINDS NEAR OR ABOVE CRITERIA
THIS EVENING AND MOST OF TONIGHT FOR THOSE AREAS.

WIND DIRECTION EVEN BECOMES MORE FAVORABLE BY SUNDAY AFTERNOON INTO
MONDAY FOR HIGH WIND EVENT FROM SOUTHERN WIND RIVER MOUNTAINS TO
KCPR. ALTHOUGH WILL HIT WINDS HARD ACROSS THESE WIND PRONE AREAS
TONIGHT AND EARLY SUNDAY...WILL GO EVEN STRONGER BY SUNDAY AFTN
AND HOIST A HIGH WIND WATCH. THIS WATCH WILL ALSO INCLUDE THE
ABSAROKA RANGE AND CODY. OVERALL...ALL MODELS SUPPORT THIS
SCENARIO. MOST OF WIND RIVER BASIN SHOULD BE SHELTERED FROM THESE
STRONG WINDS THROUGH SUNDAY...BUT MONDAY COULD BE DAY INVERSION IS
BROKEN RESULTING IN WINDY DAY JUST ABOUT EVERYWHERE.

OTHERWISE...IT WILL BE DRY EAST OF THE DIVIDE WITH THE EXCEPTION
OF THE BIG HORN MOUNTAINS. RH FIELDS SUPPORT PTCLDY TO MOCLDY
SKIES EAST OF THE DIVIDE INTO TUESDAY. HOWEVER...THE LOWER
ELEVATIONS COULD BE MOCLR AT TIMES SUNDAY AND SUNDAY NIGHT DUE TO
THE DOWNWARD FORCING/DRYING. AND WITH THE EXCEPTION OF THE WESTERN
MOUNTAINS...TEMPS WILL BE AT OR ABOVE NORMAL THROUGH TUESDAY
WITH THE DOWNSLOPING WINDS ACROSS THE RIVERTON CWA.

WILL LET LATER SHIFTS ADJUST TIMING OF WIND AND SNOW AMOUNTS IF
NECESSARY. THIS WILL HAVE TO BE THE CASE FOR THE HIGH WIND WARNING
IN ZONES 2-3...SPCLY SINCE WARNING WILL LIKELY NEED TO BE EXTENDED.
OTHERWISE...HIGHLIGHTS WILL BE OUT BY LATE THIS AFTN.

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY
FORECAST FOR THIS PERIOD WEIGHTED HEAVILY TOWARD THE
ECMWF...ESPECIALLY IN THE LATER HALF OF THE PERIOD. OMEGA BLOCK
REMAINS OVER THE NORTH CENTRAL PACIFIC AND BERING SEA THROUGH THE
PERIOD WITH STRONG PROGRESSIVE ZONAL FLOW OVER THE U.S. GFS
OPERATIONAL BECOMES INCREASINGLY OUT OF PHASE WITH GEFS MEAN AND
ECMWF AS IT ATTEMPTS TO SPLIT SHORTWAVE ENERGY AROUND TOP OF
BERING SEA RIDGE AND DOWN WEST COAST OF NORTH AMERICA RATHER THAN
THIS ENERGY TAKING THE PATH OF LEAST RESISTANCE BY UNDERCUTTING
THIS RIDGE. THEREFORE GFS BRINGS A MUCH STRONGER SHORTWAVE ACROSS
AREA THURSDAY. FEW CHANGES MADE TO GOING FORECAST WITH HIGH CHANCE
OR LIKELY POPS MAINTAINED ACROSS THE WESTERN MOUNTAINS THROUGH THE
PERIOD...WITH THE LOW-END POPS BEHIND SHORTWAVE PASSAGE TUESDAY
AND THE HIGH-END POPS AHEAD OF AND WITH SHORTWAVE PASSAGE
WEDNESDAY AND WEDNESDAY NIGHT. THIS NEXT SHORTWAVE IS EXPECTED TO
DRIVE A COLD FRONT INTO NORTHERN WYOMING THURSDAY WITH SOME LOW
POPS ACROSS THE NORTHERN BIG HORN BASIN THROUGH JOHNSON COUNTY.
ECMWF SHOWS STRONG WARM AIR ADVECTION ALONG WITH DRYING IN THE
WEST FRIDAY AND SATURDAY. HOWEVER FORECAST WAS WEIGHTED MORE
TOWARD EARLY JANUARY CLIMATOLOGY MAINTAINING HIGH CHANCE POPS
ACROSS THE WEST WITH NEAR OR SLIGHTLY ABOVE SEASONAL TEMPERATURES
AND BREEZY TO WINDY CONDITIONS EAST OF THE DIVIDE.

.AVIATION...
WIDESPREAD LIGHT TO MODERATE SNOW WILL CONTINUE FAR WESTERN
MOUNTAINS AND VALLEYS TONIGHT. THE ASSOCIATED IFR CONDITIONS WILL
IMPACT KJAC TONIGHT THROUGH SUNDAY. AREAS OF MVFR CONDITIONS IN
LIGHT SNOW ARE EXPECTED FARTHER TO THE EAST...IMPACTING KBPI AND
KPNA TONIGHT AND SUNDAY. VFR CONDITIONS WILL PREVAIL EAST OF THE
DIVIDE. STRONG TO VERY STRONG WEST/SOUTHWEST WIND WILL CONTINUE OVER
THE HIGHER TERRAIN OF WESTERN WYOMING...IN THE LEE OF THE ABSAROKA
MOUNTAINS AND THROUGH THE WIND CORRIDOR FROM JUST NORTHEAST OF KRKS
TO KCPR. LCL BLOWING SNOW WILL REDUCE VISIBILITY AND CREATE BRIEF
WHITEOUT CONDITIONS.
