AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1045 PM MST SAT DEC 1 2012

.SHORT TERM...SATURDAY NIGHT THROUGH TUESDAY...ISSUED AT 231 PM

ANOTHER ACTIVE DAY OF WEATHER ACROSS THE REGION AS ANOTHER WAVE OF
PRECIPITATION MOVES THROUGH THE REGION. PRECIPITATION HAS BEEN A BIT
SPOTTIER TODAY THAN YESTERDAY. IT HAS BEEN RATHER WARM WITH SNOW
LEVELS GENERALLY RUNNING 7000 TO 7500 FEET WITH A LITTLE SNOW
MIXING WITH THE RAIN IN THE VALLEYS BUT WITH LITTLE OR NO
ACCUMULATION. HOWEVER...WITH WARMER TEMPERATURES AND A BIT MORE
INSTABILITY THERE HAVE BEEN A FEW LIGHTNING STRIKES REPORTED
ACROSS NORTHWESTERN WYOMING. HOWEVER...IT IS NOT WIDESPREAD ENOUGH
TO PUT INTO THE FORECAST. POCATELLO RADAR SHOWS ANOTHER PLUME OF
MOISTURE HEADING TOWARD WYOMING SO WE HAVE MAINTAINED CONTINUITY
FOR TONIGHT WITH LIKELY TO CATEGORICAL POPS ACROSS MOST OF WESTERN
WYOMING. WINDS HAVE BEEN GUSTY THROUGH THE SOUTHWESTERN WIND
CORRIDOR AS WELL AS EAST OF THE ABSAROKAS BUT HAVE STAYED BELOW
WARNING CRITERIA SO NO HIGHLIGHTS WILL BE NEEDED FOR TONIGHT.
SOME SNOW WILL FALL ACROSS THE WIND RIVER RANGE AND ABSAROKAS BUT
SHOULD REMAIN SUB ADVISORY FOR TONIGHT IN MOST AREAS EXCEPT FOR
THE HIGHEST SPOTS.

THE MAIN EVENT STILL LOOKS TO BE ON SUNDAY AS THE MOST POWERFUL
UPPER LEVEL DISTURBANCE AND A COLD FRONT MOVE INTO THE AREA. FIRST
WEST OF THE DIVIDE BETTER FORCING WILL BRING ANOTHER ROUND OF HEAVY
SNOW TO THE REGION WITH AN ADDITIONAL FOOT POSSIBLE ACROSS THE
HIGHER WEST FACING SLOPES. IN ADDITION...WINDS WILL BE QUITE STRONG
WITH SOME GUSTS OVER 75 MPH ACROSS THE HIGHER PEAKS THAT WILL BLOW
AND DRIFT THE SNOW. AS THE COLD FRONT PASSES LATE SUNDAY AFTERNOON
AND EVENING SNOW LEVELS WILL DROP DOWN THE VALLEY FLOORS WITH A
PERIOD OF SNOW BEFORE THE PRECIPITATION ENDS AFTER MIDNIGHT SUNDAY
NIGHT. WE ARE STILL LOOKING AT ACCUMULATIONS APPROACHING 3 FEET IN
SOME OF THE HIGHER WESTERN FACING SLOPES AS WELL. THERE COULD EVEN
BE A FEW LIGHTNING STRIKES AS WELL BUT AGAIN NOT WIDESPREAD ENOUGH
TO PUT IN THE GRIDS.

MEANWHILE...EAST OF THE DIVIDE THE MAIN STORY TOMORROW WILL BE THE
WIND. EXPECT THE PRESSURE GRADIENT TO CONTINUE TO TIGHTEN IN SUNDAY
MORNING AS THE COLD FRONT APPROACHES THE AREA FROM THE NORTHWEST.
MODELS CONTINUE TO SHOW 700 MB WINDS OF 50 TO 55 KNOTS OVER THE AREA
AND GOOD MIXING FROM TEMPERATURES POSSIBLY APPROACHING RECORD
HIGHS...WE WILL CONTINUE THE HIGH WIND WATCH FOR NATRONA COUNTY AS
WELL AS THE GREEN AND RATTLESNAKE RANGES. WE WILL ALSO ISSUE A HIGH
WIND WATCH FOR THE ABSAROKAS AS WELL. AS FAR AS SNOWFALL...THE
ABSAROKAS AND WIND RIVER RANGE WILL LIKELY SEE ADVISORY LEVEL
AMOUNTS AND THESE WILL PROBABLY BE ISSUED EARLY SUNDAY MORNING.
ACROSS THE LOWER ELEVATIONS...WE STILL FEEL MOST AREAS WILL HAVE
ONLY SLIGHT CHANCES LATER SUNDAY EVENING AS THE FRONT CROSSES AND
MANY AREAS WILL SEE RAIN INSTEAD OF SNOW WITH THE WARMING DOWNSLOPE
FLOW. MODELS HAVE SHOWN A BIT MORE PRECIPITATION ACROSS SOUTHERN
SWEETWATER COUNTY SO WE UPPED POPS AND QPF A BIT IN THAT VICINITY.

QUIET WEATHER WILL RETURN ON MONDAY AS HIGH PRESSURE BUILD ACROSS
THE AREA. TEMPERATURES WILL BE COOLER BUT ONLY FALL BACK TO LEVELS
THAT ARE CLOSE TO NORMAL FOR THIS TIME OF YEAR. THE NEXT WEATHER
MAKER THAN APPROACHES ON TUESDAY WITH THE NEXT CHANCE FOR SNOW
ACROSS THE WEST.

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY

BY TUESDAY NIGHT MOUNTAIN SNOWFALL AND VALLEY RAIN AND SNOW WILL BE
WELL UNDERWAY IN WESTERN WY DUE TO ISENTROPIC LIFT OUT AHEAD OF THE
NEXT APPROACHING SHORTWAVE TROUGH WITH THIS SNOWFALL CONTINUING
THROUGH WEDNESDAY. WEST SOUTHWEST WINDS WILL INCREASE ALONG THE
SOUTHERN WIND CORRIDOR AS WELL AS ALONG THE LEE SLOPES OF THE
ABSAROKA AND WIND RIVER MOUNTAINS TUESDAY NIGHT AS THE PRESSURE
GRADIENT TIGHTENS AND THE FLOW BACKS IN RESPONSE TO THE APPROACHING
TROUGH. THIS SHORTWAVE TROUGH WILL EXTEND FROM A CLOSED LOW THAT
WILL BE CLOSING OFF AND TRACKING EAST ACROSS CANADA. AS THE MAIN
PORTION OF THE TROUGH TRACKS EAST TO OUR NORTH...SOME PRECIP WILL
SPILL OVER THE DIVIDE FROM WEST TO EAST WEDNESDAY NIGHT INTO
THURSDAY. SIGNIFICANT SNOWFALL ACCUMULATION SHOULD STACK UP IN THE
WESTERN MOUNTAINS FROM THIS WEATHER FEATURE DURING THE PERIOD
TUESDAY NIGHT THROUGH WEDNESDAY NIGHT. THIS TROUGH WILL DRIVE A SLOW
MOVING BACKDOOR COLD FRONT SOUTH ACROSS THE STATE DROPPING HIGHS BY
AROUND 15 DEGREES BY THURSDAY. THIS TROUGH AND ASSOCIATED SURFACE
COLD FRONT WILL NOT PUSH DIRECTLY SOUTH ACROSS WYOMING LIKE EARLIER
MODEL RUNS HAD ALLUDED TO...RATHER WE JUST GET GLANCED BY THIS
FEATURE. THEN ON FRIDAY AND SATURDAY A STRONGER NEGATIVELY TILTED
UPPER LEVEL TROUGH WILL BE APPROACHING THE CWA FROM THE NORTHWEST
KEEPING TEMPERATURES ON THE RELATIVELY COOL SIDE ALONG WITH LIGHT
SNOW IN THE WEST. BY LATER SATURDAY AN ASSOCIATED CANADIAN COLD
FRONT WHICH WILL APPROACH NORTHERN WYOMING BY LATE SATURDAY AND WILL
HELP INCREASE THE CHANCES FOR SNOW IN THE NORTHWEST AND NORTH.
