AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
928 PM MST TUE FEB 28 2012

.SHORT TERM...TONIGHT THROUGH FRIDAY

THE MID LEVEL CIRCULATION HAS ALREADY ACCELERATED AND EXITED EAST
NORTHEAST INTO THE NORTHERN PLAINS. WRAP AROUND MOISTURE CONTINUES
TO GIVE AREAS NORTH AND EAST OF THE OWL CREEK MOUNTAINS PERIODS OF
SNOWFALL. THIS SNOW SHOULD BE ENDING RIGHT AROUND 01Z WHEN THE
LAST OF THE WINTER WEATHER ADVISORIES EXPIRE. THE SNOWFALL WAS
DYNAMICALLY DRIVEN WITHOUT THE HELP OF ORTHOGRAPHICS GIVEN THE
LACK OF A HIGH TO THE NORTH AND RESULTED IN A WEAK SURFACE
GRADIENT. SNOWFALL RANGED FROM 3 TO 8 INCHES ACROSS MUCH OF THE
AREA UNDER THE ADVISORY IN CENTRAL AND NORTHERN WYOMING WITH
GENERALLY LESS OVER SOUTHERN WYOMING. THE HEAVIEST ACCUMULATIONS
SEEM TO OCCUR ALONG AND TO THE LEFT OF THE MID LEVEL STORM TRACK.
THE JET COUPLET LAST NIGHT AND THE Q VECTOR FORCING TODAY ALSO
HELPED.

THEN THE ATTENTION QUICKLY SHIFTS TO A SNOW EVENT ANTICIPATED FOR
WESTERN WYOMING FOR WEDNESDAY AND WEDNESDAY NIGHT. AFTER A
TRANSITORY FLAT RIDGE AXIS QUICKLY TRACKS ACROSS WYOMING AROUND
12Z WEDNESDAY...A DIFLUENT STRENGTHENING WESTERLY FLOW WILL ONCE
AGAIN ESTABLISH ITSELF OVER THE ARES WEST OF THE RIDGE AXIS FOR
THE REST OF WEDNESDAY AHEAD OF AN APPROACHING OPEN PACIFIC TROUGH
ALREADY ABOUT TO MAKE LANDFALL ONTO THE PACIFIC COAST. THIS SPELLS
SNOWFALL FOR WESTERN WYOMING WITH A GOOD UPSLOPE COMPONENT
DELIVERING ADDITIONAL SNOWFALL TO THE HIGHER ELEVATIONS. THE
VIGOROUS LEAD SHORTWAVE WITHIN THIS BROAD TROUGH WILL PACK ANOTHER
STRONG PACIFIC COLD FRONT IN ITS WAKE WHICH WILL CRANK THE WINDS
UP ONCE AGAIN ACROSS THE CWA LATE WEDNESDAY AND WEDNESDAY NIGHT
INCLUDING THE AREA AFFECTED BY THE WINTER STORM WATCH THAT HAS
ALREADY BEEN ISSUED FOR THE ANTICIPATED AFOREMENTIONED SNOW EVENT
EXPECTED FOR WESTERN WYOMING. ONCE AGAIN...THE MID LEVEL COLD AIR
WILL NOSE RIGHT INTO THE MIDDLE OF THE CWA IN THE FORM OF A
KATAFRONT. ALTHOUGH WE ARE ONLY LOOKING AT BORDERLINE WINTER STORM
SNOW AMOUNTS FOR THE WEST...BLOWING SNOW ASSOCIATED WITH THE
ASSOCIATED COLD FRONT WOULD JUSTIFY A WATCH AT THIS STAGE OF THE
GAME. THE OVERALL FLOW WILL BE OUT OF THE WEST SOUTHWEST WHICH
ALSO FAVORS THE WEST SLOPE OF THE WIND RIVER MOUNTAINS WITH EVEN
SOUTH PASS LIKELY GETTING SIGNIFICANTLY IMPACTED WEDNESDAY EVENING. WITH
THESE TYPES OF FRONTS...ONE CAN EXPECT AT LEAST SOME BRIEF SPOTTY
PRECIP AT SOME POINT EAST OF THE DIVIDE...IN THIS CASE DURING THE WEE
HOURS OF THURSDAY MORNING BUT FOR NOW ONLY WENT WITH SLIGHT CHANCE
SO WE MATCH UP WITH OUR NEIGHBORS.

THURSDAY WILL FEATURE A MOIST AND UNSTABLE AIRMASS WITH OTHER
RIPPLES IN THE WESTERLY FLOW WITH MANY AREAS SEEING CONVECTIVE
SNOW SHOWERS...ESPECIALLY IN THE WEST AND MOUNTAINS.

ON FRIDAY THE AIRMASS WILL STABILIZE AND THE THREAT OF STRENGTHENING
WIND WILL INCREASE. THE THREAT OF ANY MOUNTAIN WAVE POTENTIAL CAN
BE INTERROGATED BY LATER SHIFTS FOR BEGINNING LATE FRIDAY. THE
GRADIENT SURFACE AND ALOFT WILL INCREASE FRIDAY. THIS WILL KEEP
LIGHT SNOW GOING IN THE FAR WEST WITH A WESTERLY UPSLOPE COMPONENT
GOING ON THERE.

NO BIG FLUCTUATIONS IN TEMPERATURES ARE ANTICIPATED WITH RELATIVELY
SEASONAL TEMPS EXPECTED FOR LATE FEBRUARY.

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY

ROUGH AXIS PULLS INTO THE PLAINS FRIDAY AND FRIDAY NIGHT...WITH
STRONG MOIST NORTHWEST FLOW DEVELOPING ACROSS THE FORECAST
AREA...AND LASTING THROUGH SATURDAY NIGHT. THIS WILL RESULT IN A
DECENT CHANCE FOR PERIODS OF SNOW...MAINLY OVER THE
NORTHWEST/NORTHERN MOUNTAINS...AND ADJACENT LOWER ELEVATIONS...AS
WELL AS THE POTENTIAL FOR SOME STRONG/HIGH WINDS. HAVE INCREASED THE
WINDS OVER MUCH OF THE AREA FOR SATURDAY AND SUNDAY AS MODELS STILL
INDICATE A DECENT PRESSURE GRADIENT REINFORCED BY STRONG WINDS ALOFT
THROUGH SATURDAY NIGHT.

MEDIUM RANGE MODELS THEN SHOW RIDGING DEVELOPING SUNDAY...BUT DIFFER
ON THE AMPLITUDE. EITHER WAY...WARMER AND DRIER CONDITIONS WITH MUCH
LIGHTER WINDS WILL PREVAIL SUNDAY. GLOBAL MODELS STILL SIGNIFICANTLY
DIVERGE ON HOW A TROUGH WILL AFFECT THE AREA MONDAY AND TUESDAY OF
NEXT WEEK. HOWEVER...THE GENERAL TREND IS FOR A LEADING SHORTWAVE
TROUGH PUSHING ACROSS EXTREME NORTHERN ROCKIES MONDAY/MONDAY
NIGHT...WITH A MORE PRONOUNCED DIGGING TROUGH ACROSS THE
WEST/INTERMOUNTAIN WEST ON TUESDAY...ESPECIALLY WITH THE 00Z AND THE
12Z GFS...WITH NO INDICATION OF THE TROUGH SPLITTING. WILL KEEP
PRECIPITATION CHANCES LIMITED TO THE HIGHER ELEVATIONS OF THE WEST
ON MONDAY...KEPT BROAD BRUSH LOW POPS ACROSS THE WEST MONDAY NIGHT
AND TUESDAY AND INTRODUCED SOME SLIGHT CHANCE POPS TO SOME OF THE
LOWER ELEVATIONS AND ACROSS THE SOUTH. WINDS WERE INCREASED A BIT
