AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
337 PM MST SAT DEC 1 2007

.SHORT TERM...TONIGHT THROUGH TUESDAY
FORECAST WORKING OUT ABOUT AS EXPECTED WITH THE ONLY CAVEAT BEING
THE SECONDARY SHORTWAVE COMING UP FROM THE SW NOW. THE GFS
DEPICTED THIS YESTERDAY BUT THE NAM HAD IT STAYING WELL TO THE
SOUTH ACROSS COLORADO. THE GFS WILL WIN THIS ROUND AND HAVE ADDED
MORE POPS THIS EVENING ACROSS THE TRACK OF THIS SYSTEM. POTENTIAL
FOR EVEN HIGHER POPS DEPENDING ON HOW THIS SYSTEM REACTS WHEN IT
HITS THE COLD DOME ACROSS CENTRAL COLORADO. AFTER THAT...THE MAIN
FOCUS WILL BE ISENTROPIC UPGLIDE SNOW ACROSS THE WEST FROM AS
EARLY AS LATE SUNDAY AFTERNOON THROUGH TUESDAY WITH ONLY BRIEF
RESPITES. OTHER CONCERN IS TEMPERATURES WARM ENOUGH WHERE THE
VALLEYS COULD CHANGE TO RAIN AT TIMES LATE IN THE AFTERNOON
MONDAY AND AGAIN TUESDAY. THE OTHER SERIOUS CONCERN IS HIGH WIND
POTENTIAL ACROSS AREAS EAST OF THE DIVIDE FROM SUNDAY NIGHT
THROUGH AT LEAST TUESDAY MORNING. WILL ISSUE THE FIRST HIGH WIND
WATCH FOR THE CODY FOOTHILLS AND ABSAROKA MOUNTAINS FROM 03-18Z
MONDAY. CROSS SECTION AROUND CLARK SHOWING STABLE MOUNTAIN TOP
LAYER BY LATE TOMORROW ALONG WITH 40-50KT H7 WINDS OVER YNP.
SOUNDINGS NOT SHOWING A MTN TOP INVERSION YET BUT THIS WILL HAVE
TO BE WATCHED. WITH STRONG LEE TROUGHING DEVELOPING AND IMPRESSIVE
THERMAL GRADIENT FROM THE HIGH PLATEAU TO THE WEST...THIS MAY BE
ENOUGH FOR GAP FLOW TO HIT HIGH WIND CRITERIA. MTN WAVE POTENTIAL
IS THERE ALSO AND WILL JUST NEED TO BE ANALYZED INTO SUNDAY.
POTENTIAL FOR HIGH WINDS AT TIMES CONTINUE INTO TUESDAY MORNING.
PARAMETERS LOOK EVEN MORE IMPRESSIVE FOR MONDAY AND/OR MONDAY
NIGHT INTO TUESDAY MORNING. EVEN THE LANDER FOOTHILLS WILL HAVE TO
BE WATCHED BUT WITH H7 FLOW MORE WNW WILL NEED TO SEE HOW THIS
DEVELOPS AS WE NEED MORE CROSS BARRIER FLOW. NW FLOW HIGHER UP
THOUGH COULD ACT AS A CRITICAL LAYER. THE GAP FLOW FROM MUDDY GAP
TO CASPER WILL ALSO BE IN FULL FORCE WITH ONLY NEGATIVE BEING THE
AFOREMENTIONED NW H7 FLOW. TEMPERATURES WILL BE TRICKY AS THE WARM
TO ABOVE 0C LATER MONDAY INTO TUESDAY ALONG WITH MILDER LOWS IN WIND.

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY
NW FLOW ALOFT FOR TUE NIGHT WITH MOISTURE IN THE FLOW. SOME LIGHT
SNOW FOR THE MOUNTAINS WITH DRY WEATHER ELSEWHERE. ON WED THE GFS
MODEL HINTS AT A DRIER DAY WHILE THE ECMWF MODEL IS WETTER. WILL
KEEP THE PRECIP CHANCE IN THE MTS WITH ONLY A SLIGHT CHANCE ACROSS
THE LOWER ELEVATIONS. ON THURSDAY THE GFS MODEL BRINGS A WEATHER
SYSTEM ACROSS THE REGION. THE ECMWF MODEL SHOWS SOME RIDGING AHEAD
OF A DIGGING TROUGH ALONG THE WEST COAST. GFS MODEL HAS A WEAK
TROUGH OFF THE WEST COAST THU. FOR NOW WILL STAY THE COURSE AND
LEAVE A CHANCE OF SNOW IN THE MTS AND FAR WEST VALLEYS WITH DRY
WEATHER FOR LOWER ELEVATIONS EAST OF CONTINENTAL DIVIDE. ECMWF
INDICATES A DECENT TROUGH PASSAGE FRIDAY WITH A WEAKER SOLUTION
SHOWN ON THE GFS MODEL. THIS LEADS TO A CHANCE OF SNOW FOR THE MTS
AGAIN WITH A SLIGHT CHANCE IN THE BASINS. SATURDAY LOOKS TO BE
MOSTLY DRY ASIDE FROM SOME LIGHT SNOW FOR THE MTS. BIG MODEL
DIFFERENCE WITH OVERALL WEATHER PATTERN BY NEXT SAT WITH THE ECMWF
SHOWING A WEATHER SYSTEM APPROACHING THE REGION FROM THE WEST. THE
GFS MODEL HAS A NW FLOW AND A TROUGH GLANCING THE AREA. LOW
CONFIDENCE FORECAST IN THE EXTENDED DUE TO POOR MODEL AGREEMENT.
AS FOR TEMPS...SEASONAL TO ABOVE NORMAL HIGHS NEXT WEEK WITH COLD
LOWS AT NIGHT.

&&

.AVIATION...
LIGHT TO MODERATE SNOW SHOWERS WILL CONTINUE THIS EVENING WITH MVFR
CIGS AND VSBYS.  CONDITIONS WILL GRADUALLY IMPROVE THIS
EVENING...BECOMING VFR BY 06Z MOST AREAS.  THE FLOW WILL BECOME WEST
OVERNIGHT WITH SOUTHWEST TO WEST BREEZES INCREASING IN THE TYPICAL
LOCATIONS.  LOOK FOR THESE WINDS TO PICK ESPECIALLY SUNDAY AFTERNOON
AND NIGHT INTO MONDAY.  SNOW WILL BEGIN TO MOVE INTO NORTHWEST
WYOMING LATE SUNDAY WITH THE MAIN IMPACT BEING AROUND KJAC.

&&

.FIRE WEATHER...
MORE AREAS OF SNOW WILL CONTINUE INTO THE EVENING HOURS AND IN
SOME AREAS OVERNIGHT. THE MAIN FORECAST PROBLEM AFTER TONIGHT WILL
BE SNOW IN THE WESTERN MOUNTAINS AND STRONG TO POTENTIALLY
DAMAGING WINDS IN OTHER LOCATIONS SUNDAY NIGHT THROUGH TUESDAY.
ALL AREAS EAST OF THE CONTINENTAL DIVIDE WILL NEED TO BE WATCHED
FOR VERY STRONG WINDS ALONG WITH MANY MOUNTAIN LOCATIONS. MIN RHS
WILL LOWER EAST DAY EAST OF THE DIVIDE ALONG WITH WARMING TEMPERATURES.
