AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1040 AM MST THU NOV 17 2011

.UPDATE...

SNOWFALL HAS BEGUN ACROSS PORTIONS OF WESTERN WYOMING THIS
MORNING...WITH OBSERVATIONS NOTING THAT SOME SNOWFALL IS MODERATE
TO HEAVY ACROSS THE WESTERN MOUNTAINS AND VALLEYS. BECAUSE OF
THESE ONGOING CONDITIONS...THE WINTER STORM WARNING FOR THESE
AREAS IS IN EFFECT NOW. AS SNOWFALL PROGRESSES... SIGNIFICANT
ACCUMULATIONS WILL BE POSSIBLE ACROSS OTHER AREAS OF THE
CWA...WITH ADDITIONAL WINTER WEATHER HIGHLIGHTS PRESENT. PLEASE
CHECK THE WINTER WEATHER HIGHLIGHT PRODUCT...AND WIND HIGHLIGHT
PRODUCT FOR INFORMATION REGARDING ONGOING HAZARDS.

.SHORT TERM...TODAY THROUGH SATURDAY NIGHT

A VERY ACTIVE FORECAST IN THE SHORT TERM BEGINNING WITH AN ONGOING
HIGH WIND EVENT AND ENDING WITH A POTENTIALLY SIGNIFICANT SNOW EVENT
ACROSS THE CWA.  MOUNTAIN WAVES WILL BE BREAKING ALONG THE EASTERN
SLOPES OF THE ABSAROKAS THIS MORNING WITH WIND GUSTS OVER 75 MPH
ALREADY REPORTED WITH GAP FLOW AT THE MOUTH OF THE CLARKS FORK
CANYON.  THE POTENTIAL FOR HIGH WIND EXISTS IN THIS AREA INTO THE
AFTERNOON HOURS TODAY.  ADDITIONALLY...HIGH WIND IS POSSIBLE ALONG
THE WIND CORRIDOR INCLUDING THE GREEN MOUNTAINS AND THE CASPER AREA
TODAY.  H7 WIND OF 50 TO 55 KTS IS EXPECTED TO DEVELOP AS MID LEVEL
FLOW BACKS TO THE WEST WITH THE APPROACH OF A DIGGING TROUGH ALONG
THE PACIFIC COAST.  THE THREAT FOR HIGH WIND IN THIS AREA WILL
DIMINISH AS THE SUN GOES DOWN THIS EVENING WITH DECOUPLING OF THE
BOUNDARY LAYER.  AS FLOW BECOMES SOUTHWESTERLY LATE TODAY LEE
TROUGHING AND MOUNTAIN WAVE POTENTIAL DEVELOPS FOR THE LANDER
FOOTHILLS.  A HIGH WIND WATCH IS IN EFFECT FOR THIS AREA OVERNIGHT
TONIGHT.  THERE IS LESS CERTAINTY IN THIS AREA SO WILL PASS TO THE
NEXT SHIFT FOR FURTHER ANALYSIS.

THE DIGGING TROUGH CONTAINS A COMPLEX MISHMASH OF SHORTWAVES THAT
WILL BE AFFECTING THE AREA OVER THE NEXT FEW DAYS. LIGHT SNOW WILL
BEGIN LATER THIS MORNING IN THE FAR WEST AS ISENTROPIC LIFT SETS UP.
 THE ATMOSPHERE WILL BE RELATIVELY DRY DURING THIS PERIOD ALLOWING
FOR MAYBE A COUPLE INCHES OF ACCUMULATION IN THE TETONS AND PORTIONS
OF YELLOWSTONE NATIONAL PARK BEFORE SUNDOWN.  SNOWFALL WILL INCREASE
IN INTENSITY AND COVERAGE THIS EVENING AS A DEFORMATION AXIS SETS
UP.  SNOWFALL RATES OF UP TO AN INCH PER HOUR ARE POSSIBLE AT TIMES
IN THE FAR WESTERN MOUNTAINS OVERNIGHT THROUGH THE DAY FRIDAY.  12
TO 18 INCHES OF SNOW ARE POSSIBLE IN AREAS OF THE TETONS AND
SOUTHWEST PORTIONS OF YELLOWSTONE AS WELL AS IN THE TOGWOTEE PASS
AREA. THE JACKSON VALLEY SHOULD SEE 5 TO 9 INCHES OF SNOW WITH
THE HIGHER AMOUNTS IN THE NORTHERN END OF THE VALLEY. WINTER
WEATHER ADVISORIES WILL LIKELY BE NEEDED ELSEWHERE IN THE WEST. A
WINTER STORM WATCH IS IN EFFECT FOR THESE AREAS. THE TEMPERATURE
FORECAST IS A BIT TRICKY FRIDAY WITH A COLD FRONT PLUNGING
SOUTHWARD DURING THE DAY. WENT A LITTLE BELOW GUIDANCE FOR HIGHS
FRIDAY IN THE WIND RIVER BASIN AS TIMING OF THE FRONT IS A LITTLE
IN QUESTION AND THE POTENTIAL FOR PRECIPITATION TO SPILL OVER EAST
OF THE DIVIDE DURING THE AFTERNOON HOURS BRINGING EVAPORATIVE
COOLING INTO THE EQUATION. LOWERED TEMPERATURES FRIDAY NIGHT AS
COLD POST FRONTAL AIR MOVES IN. SNOW WILL CONTINUE THROUGH
SATURDAY FOR MUCH OF THE AREA EAST OF THE DIVIDE. WILL CONTINUE
MONITORING FOR THE POTENTIAL NEED FOR HIGHLIGHTS LATE FRIDAY INTO
SATURDAY MORNING. ANOTHER COLD NIGHT IS IN STORE FOR SATURDAY
NIGHT AS MUCH OF THE AREA CLEARS OUT AND NOCTURNAL INVERSIONS
DEVELOP. MOST AREAS WILL SEE LOWS IN THE SINGLE DIGITS WITH AREAS
WEST OF THE DIVIDE DIPPING BELOW ZERO.

.LONG TERM...SUNDAY THROUGH THURSDAY

COLD AIRMASS WILL LINGER OVER AREA SUNDAY WITH SOME SNOW SHOWERS
LINGERING ACROSS THE WESTERN MOUNTAINS ALONG AND SOUTH OF INTERSTATE
80.  A WARMING TREND FOLLOWS MONDAY THROUGH WEDNESDAY WITH THE
AIRMASS DRYING OUT ACROSS THE WEST AND SOUTH.  CHANCES OF SNOW
INCREASE ACROSS THE WEST THANKSGIVING DAY AS THE NEXT PACIFIC STORM
SYSTEM MOVES ONSHORE.  BREEZY TO WINDY AREAS WILL DEVELOP ACROSS THE
WIND CORRIDORS WEDNESDAY AND THANKSGIVING DAY.

MEDIUM RANGE GLOBAL MODELS IN GOOD OVERALL AGREEMENT WITH BACKING
FLOW AND WARMER...DRIER AIRMASS PUSHING INTO THE AREA MONDAY THROUGH
WEDNESDAY.  ECMWF AND GFS SHOW SUBSTANTIAL SPREAD WITH THEIR
HANDLING OF NEXT PACIFIC TROUGH LATE IN THE WEEK BUT HAVE TRENDED
SLOWER OVERALL WITH THIS SYSTEM.  ON SUNDAY...TRAILING CLIPPER MOVES
INTO THE NORTHERN HIGH PLAINS WHILE SW UPPER LOW IS KICKED INLAND
INTO BAJA CALIFORNIA/SW U.S. SUNDAY NIGHT.  BOTH MODELS ARE BRINGING
UP SOME MOISTURE AND UPGLIDE INTO THE SOUTH AHEAD OF THIS SYSTEM
WITH THE ECMWF SPREADING MORE MOISTURE NORTHWARD ACROSS WESTERN
WYOMING.  BOTH MODELS THEN DRY THE AIRMASS OUT TUESDAY AS THE SW
UPPER LOW EJECTS ACROSS THE SOUTHERN PLAINS.   SOUTHWEST FLOW
INCREASES WEDNESDAY WITH INTENSIFYING LEE SIDE SURFACE TROUGH...AND
WINDS PICKING UP ACROSS THE WIND CORRIDORS.  ECMWF SPLITS NEXT
INCOMING PACIFIC TROUGH THURSDAY WHILE GFS KEEPS TROUGH INTACT AND
IS FASTER BRINGING IT ACROSS ROCKIES THANKSGIVING DAY.  PREFERRED
SLOWER ECMWF WOULD BRING CHANCES OF SNOW INTO THE WESTERN MOUNTAINS
THANKSGIVING DAY AND LEAVE SOUTHERN AND CENTRAL WYOMING DRY...BREEZY
TO WINDY AND MILD.
