AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1156 AM MST THU JAN 1 2009

SHORT TERM...TODAY THROUGH SATURDAY NIGHT
UPDATED TO UPGRADE THE WINTER STORM WATCHES FOR THE STAR VALLEY...
SALT AND WYOMING RANGES AND THE PINEDALE TO BONDURANT ZONE. SNOW
IS COMING DOWN UP TO AN INCH PER HOUR IN THE NRN STAR VALLEY AND
UP TO A HALF INCH PER HOUR AROUND PINEDALE. MAIN FORECAST
CHALLENGE IS THE WARMING THAT WILL OCCUR TONIGHT INTO FRIDAY
MORNING THAT HAS THE POTENTIAL TO CHANGE SOME OF THESE AREAS TO
RAIN. HOWEVER...DUE TO THE CURRENT SNOWFALL AND THE POSSIBILITY
THAT IT WILL NEVER CHANGE OVER DUE TO STEADY PCPN FALL...WE WILL
UPGRADE THE WATCH IMMEDIATELY. ALSO POSTED A WINTER WEATHER
ADVISORY FOR THE WIND RIVER MOUNTAINS THROUGH FRIDAY EVENING. SOME
WINTER STORM AMOUNTS WILL FALL IN THE NRN RANGE AND THAT WILL BE
INDICATED IN FUTURE STATEMENTS. SOUTH PASS TRAVEL WILL BECOME QUITE
CHALLENGING LATER TONIGHT AND ESPECIALLY FRIDAY.

SHORTWAVE ZIPPING ACROSS MONTANA EARLY THIS MORNING WITH
ASSOCIATED COLD FRONT MOVING INTO NORTHERN WYOMING. SOME LIGHT
SNOW FALLING IN SHERIDAN WHICH WILL MOVE INTO NORTHERN JOHNSON
COUNTY SHORTLY. LIGHT SNOW ALSO FALLING OVER THE NORTHWEST AND
NORTHERN STAR VALLEY AND SALT RIVER RANGE. SO FAR...AMOUNTS HAVE
BEEN LIGHT FOR THE MOST PART...BUT HAVE SEEN UP TO 4 INCHES AT
RENDEZVOUS BOWL PLOT. QUITE A WINDY DAY YESTERDAY...WITH MANY
AREAS NEARLY REACHING HIGH WIND CRITERIA.

ISENTROPIC LIFT CONTINUES TODAY IN THE NORTHWEST...AND GRADUALLY
INCREASING IN THE SOUTHWEST AS THE DAY PROGRESSES.  MOISTURE ALSO
INCREASES AS THE DAY GOES ON IN THE SOUTHWEST.  THE ISENTROPIC LIFT
CONTINUES TONIGHT INTO FRIDAY BEING THE MAIN SNOWFALL DYNAMICS.
THEN BAROCLINIC LEAF DYNAMICS AND RRQ JET DYNAMICS TAKE OVER IN THE
LATE MORNING HOURS FRIDAY.  STILL LOOKS LIKE THE HEAVIEST SNOWFALL
WILL FALL IN THE TETONS AND SOUTHWEST YELLOWSTONE PARK...WITH THE
BEST SNOWFALL RATES OCCURRING WITH THE BAROCLINIC LEAF ON FRIDAY.
THE TETONS AND SOUTHWEST YNP SHOULD SEE 1 TO 2 FEET WITH LOCAL
AMOUNTS TO 3 FEET POSSIBLE.  HAVE OPTED TO DELAY THE SOUTHWEST
WINTER STORM WATCHES 12 HOURS... BECAUSE OF THE DELAY OF THE ONSET
OF THE MORE INTENSE SNOWFALL TONIGHT INTO FRIDAY.  WILL ALLOW THE
NORTHWEST WINTER STORM WARNINGS CONTINUE THROUGH 06Z SATURDAY.  SNOW
ADVISORIES MAY BE NEEDED TONIGHT AND FRIDAY FOR THE WIND RIVERS AND
ABSAROKAS.

GRADIENT TIGHTENS ONCE AGAIN LATE THIS AFTERNOON AND EVENING ACROSS
WYOMING.  GRADIENT QUITE TIGHT OVER THE ABSAROKAS AND CODY FOOTHILLS
AS WELL AS THE GREEN MOUNTAINS AND NATRONA COUNTY.  POTENTIAL EXISTS
FOR MTN WAVE ACTIVITY OVER THE CODY FOOTHILLS WITH MTN TOP INVERSION
SETTING UP TONIGHT JUST ABOVE H7.  H7 WINDS...MTN TOP LEVEL...WILL
BE 50 TO 60 KTS OVER THESE AREAS BEGINNING THIS EVENING AND
PERSISTING THROUGH 00Z SATURDAY.  HAVE INCLUDED THESE AREAS IN HIGH
WIND WATCHES FROM 6 PM THIS EVENING THROUGH 6 PM FRIDAY.  THE EAST
SLOPE OF THE WIND RIVER MOUNTAINS WILL BE CLOSE...BUT HAVE LEFT THEM
OUT OF A WATCH FOR NOW.  DECENT COLD FRONT MOVES INTO NORTHERN
WYOMING AROUND 06Z SATURDAY WHICH SETS UP AN UPSLOPE FLOW EAST OF
THE DIVIDE...ESPECIALLY FOR JOHNSON AND NATRONA COUNTIES.  THIS WILL
BRING THE SNOW TO THESE AREAS AS WELL.  IT MAY WORK ITS WAY BACK
INTO THE WIND RIVER AND BIG HORN BASINS AS WELL.  TROUGH MOVES
THROUGH SATURDAY WITH H7 TEMPS AROUND -20C MOVING IN BEHIND IT.  MAX
TEMPS SATURDAY WILL BE QUITE COLD...WITH MAX READINGS IN THE TEENS.
WINDS SLACKEN SATURDAY NIGHT AND SKY CLEARS.  THIS WILL LIKELY LEAD
TO OVERNIGHT LOWS WELL BELOW ZERO.

LONG TERM...SUNDAY THROUGH THURSDAY
NORTHWEST FLOW ON SUNDAY WITH A BREAK IN THE PRECIP FOR THE WESTERN
MTS AS ONLY ISOLATED SNOW SHOWERS ARE EXPECTED. DRY ELSEWHERE ON
SUNDAY. THE NEXT SURGE OF MOISTURE IS FORECAST FOR SUNDAY NIGHT AND
MONDAY INTO THE WESTERN MTS. THIS OCCURS AS A NEW WEATHER SYSTEM IN
THE NW FLOW MOVES TOWARD THE ROCKIES ON MONDAY. THE TROUGH MOVES
THROUGH THE REGION MONDAY NIGHT. BEST CHANCE OF SNOW WILL BE IN THE
MOUNTAINS. SCATTERED SNOW SHOWERS ELSEWHERE WITH THE COLD FRONT
PASSAGE. NW FLOW ALOFT FOR TUESDAY WITH MOISTURE IN THE FLOW FOR THE
WESTERN MOUNTAINS AGAIN. MOSTLY DRY ELSEWHERE ON TUE. THE MOIST NW
FLOW IS FORECAST TO PERSIST THROUGH WED AND THEN THE NEXT TROUGH IS
SLATED FOR NEXT THURSDAY. THIS WOULD KEEP THE CHANCE OF SNOW GOING
