AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
231 AM MST FRI NOV 9 2012

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT

MOISTURE FROM THE APPROACHING AREA OF LOW PRESSURE HAS BEGUN TO MOVE
INTO WESTERN WYOMING...WITH SNOWFALL CONTINUING TO SPREAD ACROSS THE
MOUNTAINS. SNOWFALL WILL REMAIN OVER THE AREA THROUGHOUT THE DAY
UNDER THE INFLUENCE OF THE WAVE OF LOW PRESSURE. MODERATE SNOWFALL
ACCUMULATIONS ARE ANTICIPATED...WITH A WINTER WEATHER ADVISORY IN
EFFECT FOR THE WESTERN MOUNTAINS AND VALLEYS. THE HEAVIEST SNOWFALL
APPEARS MOST FAVORABLE BEFORE NOON TODAY WITH SNOWFALL RATES OF 2
INCHES AN HOUR OR MORE. SNOWFALL RATES OF AN INCH AN HOUR WILL
CONTINUE THROUGH THE DAY. TODAY AND TONIGHT WILL HAVE THE HIGHEST
IMPACT WITH 6 TO 10 INCHES OF SNOWFALL IN THE MOUNTAINS AND 2 TO 5
INCHES POSSIBLE IN THE BASINS. SNOWFALL INTENSITY EXPECTED TO WEAKEN
LATE TONIGHT...THOUGH LIGHT SNOWFALL WILL CONTINUE THROUGHOUT
SATURDAY ACROSS THE AREA.

SNOWFALL WILL SPILL EAST OF THE DIVIDE THIS AFTERNOON...WITH
WIDESPREAD COVERAGE ANTICIPATED BY THIS EVENING. PERIODS OF
HEAVIER SNOWFALL ARE EXPECTED OVER THE BIGHORN MOUNTAINS THIS
AFTERNOON AND INTO THE EVENING HOURS. A WINTER WEATHER ADVISORY
HAS BEEN ISSUED FOR THIS AREA. MODELS INDICATE THE POTENTIAL FOR
THE DEVELOPMENT OF VERY STRONG WIND ACROSS THE WIND CORRIDOR AREA
THIS AFTERNOON. UPPER LEVEL WIND IN EXCESS OF 50 KTS HAS BEEN
SUGGESTED ON RECENT MODEL SOLUTIONS. IT IN ANTICIPATED THAT THIS
STRONG WIND WILL IMPACT THE AREA...AND A HIGH WIND WARNING IS IN
EFFECT THROUGH THE EVENING HOURS FOR THE DEVELOPMENT OF THIS WIND.
DURING THE LATER AFTERNOON AND EARLY EVENING HOURS...IT IS
POSSIBLE THAT THE COMBINATION OF STRONG WIND WITH SNOWFALL WILL
CREATE HAZARDOUS TRAVEL CONDITIONS. CONDITIONS WILL BE MONITORED
WITH PUBLIC UPDATES EXPECTED THROUGH THE DAY.

THE AXIS OF THE WAVE OF LOW PRESSURE WILL THEN APPROACH THE AREA
SATURDAY AFTERNOON AND EVENING...HELPING TO MOVE PRECIPITATION
FURTHER EAST. AN APPROACHING RIDGE OF HIGH PRESSURE IS THEN
ANTICIPATED BY SUNDAY. HOWEVER...MODELS DO INDICATE THE PRESENCE OF
SOME WRAP AROUND MOISTURE AS THE AREA OF LOW PRESSURE MOVES FURTHER
EAST. THIS WILL KEEP SOME LIGHT SNOWFALL ACROSS AREA THE WESTERN
MOUNTAINS THROUGH THE REMAINDER OF THE WEEKEND.

THE MILD TEMPERATURES WILL BE REPLACED WITH MUCH COOLER VALUES
TODAY...WITH WIDESPREAD COOLER TEMPERATURES EXPECTED BY SATURDAY.
COLDER TEMPERATURES WILL PERSIST THROUGH SUNDAY.

.LONG TERM...MONDAY THROUGH FRIDAY
FLAT RIDGE IS STILL FORECAST TO MOVE INTO THE AREA MONDAY INTO
TUESDAY WITH MODERATING TEMPERATURES. THIS LOOKS TO BE A DIRTY RIDGE
WITH PERIODS OF MID AND HIGH CLOUDS POTENTIALLY AFFECTING THE
TEMPERATURES. WE DO HAVE SOME VERY SMALL POPS IN THE WESTERN
MOUNTAINS MONDAY NIGHT AND TUESDAY BUT THEY'VE BEEN TONED DOWN FROM
THE MEDIUM RANGE PROCEDURE AND CONFIDENCE LOW THAT THERE WILL BE
ANYTHING UNDER THE RIDGE. ODDS INCREASE SOME TUESDAY NIGHT THROUGH
WEDNESDAY OF PCPN IN THE FAR WEST AS TROUGH DIGS ALONG THE WEST
COAST AND SOME INCREASE IN MOISTURE...MID LEVEL FRONT AND JET
STREAK DYNAMICS COULD POTENTIALLY COME INTO PLAY. THE ECMWF
HOWEVER...DEVELOPS THIS TROUGH OFFSHORE WITH MORE OF AN INFLUENCE
FROM THE NRN STREAM. SO KEEPING THE POPS LOW FOR NOW AND SEE IF WE
HAVE BETTER AGREEMENT TONIGHT. THE GFS THEN PUSHES THIS TROUGH
WELL TO OUR SOUTH THURSDAY INTO THURSDAY NIGHT WITH JUST A WEAKER
TROUGH PASSAGE FURTHER NORTH. THE ECMWF IS 12-18 HOURS SLOWER AND
WEAKER WITHOUT MUCH OF A NRN EXTENSION OF THESE TROUGH. JUST
KEEPING LOW POPS IN THE MOUNTAINS FOR NOW.
