AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
157 PM MST WED NOV 30 2011

.SHORT TERM...TONIGHT THROUGH SATURDAY
CANADIAN FRONT IS PUSHING THROUGH CENTRAL WYOMING ATTM WITH THE
STRONGER PUSH STILL IN MONTANA WHERE THE 6-8MB 3 HOUR PRESSURE
RISES ARE. MAIN CHANGE IN THE SCENARIO FROM YESTERDAY IS THE
SLIGHTLY FARTHER EWD SHIFT IN THE POSITION OF THE TROUGH AND UPPER
LOW. THIS EWD SHIFT HAS INCREASED THE THREAT OF SOME WEAK TO
MODERATE DYNAMICS ACROSS THE AREA...ESPECIALLY THE WEST AND SOUTH.
COOLING TOPS NOTED ACROSS THE FAR NORTH ALONG THE FRONT LIKELY
BEING AIDED BY THE NORTHERN VORT AND POSSIBLY LINKING UP WITH SWRN
IDAHO UPPER LOW. THIS INCREASE IN UPPER SUPPORT ALONG THE FRONT
WILL ALLOW FOR A LITTLE MORE SNOW TO FALL ALONG WITH EVEN STRONGER
WINDS TO DEVELOP. INCREASED SNOW AMOUNTS A LITTLE FOR LANDER
SIMILAR TO YESTERDAY...3-4 INCHES. ALSO INCREASED AMOUNTS IN THE
RED DESERT AS BOTH THE GFS AND THE ECMWF HAS MORE FORCING AND
HIGHER QPF BY UP TO A TENTH OR MORE. SURFACE PRESSURE GRADIENT IS
FAIRLY STRONG AND FORECAST TO HIT AT LEAST 18MB ACROSS THE STATE.
WOULD PREFER TO SEE AT LEAST 20MB OR MORE BUT WHEN COMBINED WITH
THE MID LEVEL FLOW OF 45 TO 55KTS IT ADDS UP TO A VERY STRONG PUSH
AND THE POTENTIAL FOR STRONG TO HIGH WINDS AND WHITEOUT CONDITIONS
WHERE AND WHEN MODERATE SNOW FALLS. THIS APPEARS MOST LIKELY OVER
NORTHERN JOHNSON...SWEETWATER COUNTY...BEAVER RIM TO JEFFREY CITY
AND ESPECIALLY OVER SOUTH PASS. I80 TRAVEL WILL LIKELY BE
SEVERELY HAMPERED LATER THIS EVENING INTO THURSDAY WITH SEVERAL
INCHES OF SNOW AND NE WINDS GUSTING 45 TO 55 MPH. SOUTH PASS COULD
EASILY BE CLOSED LATER TONIGHT AS NE WINDS SHOULD INCREASE
DRAMATICALLY AND SEE GUSTS OF 50 TO 60 MPH ALONG WITH OCCASIONAL
MODERATE SNOW. THUS THE BLIZZARD WARNING FOR SOUTH PASS. ALSO
UPGRADED OUR HIGH WIND WATCHES TO WARNINGS AS WE EXPECT THE FRONT
TO BLAST THROUGH THE WIND RIVER CANYON AND THROUGH THE WIND RIVER
BASIN THIS EVENING. WINDS SHOULD EASILY GUST 50 TO 60 MPH ALONG
THE SOUTH SLOPE OF THE OWL CREEK MTNS AND NORTHERN WIND RIVER
BASIN WITH GUSTS TO 70 MPH QUITE POSSIBLE. NOT QUITE AS STRONG AND
PROBABLY BELOW HIGH WIND CRITERIA FOR THE SOUTHERN HALF OF THE
WIND RIVER BASIN INCLUDING RIVERTON BUT STILL WIND GUSTS OF 40 TO
50 MPH OR SO. WE ARE ALSO STILL EXPECTED A HIGH POTENTIAL OF A
RARE MOUNTAIN WAVE EVENT ON THE SW WIDE OF THE WIND RIVER MTNS
TONIGHT AS THE WRF CONTINUES TO SHOW WAVE BREAKING AND A
REASONABLE POTENTIAL FOR STRONG GAP FLOW. THE WEST SLOPE OF THE
WINDS ARE COVERED BY A BLIZZARD WARNING SO THAT WILL COVER THE
LIGHTER SNOWS BUT POTENTIAL DANGEROUS NE WINDS. DOWN LOWER FROM
PINEDALE AND BIG SANDY TO NEAR FARSON NE WINDS WILL INCREASE THIS
EVENING AND PEAK LATER TONIGHT. NE WINDS OF 30 TO 40 MPH WITH
GUSTS OF 60 TO 65 ARE EXPECTED WITH THE POTENTIAL FOR STRONGER GUSTS...
ESPECIALLY WHEN COMBINED WITH LOCALIZED GAP FLOW. ALSO ADDED IN
WINTER WEATHER ADVISORIES FOR THE LANDER FOOTHILLS AND NATRONA
COUNTY WITH THE SLIGHT INCREASE IN THE DYNAMICS AND UPSLOPE. THE
SNOW WILL BE ACCOMPANIED BY GUSTY NORTH WIND...ESPECIALLY IN THE
OPEN AREAS. GRADUAL IMPROVEMENT THEN FROM N TO S ON THURSDAY WITH
SWEETWATER COUNTY AND SOUTH PASS THE SLOWEST TO IMPROVE.

NOT MUCH OF A BREAK BETWEEN SYSTEMS. THE FLOW REVERSAL BEGINS
QUICKLY THURSDAY NIGHT WITH SW WINDS DEVELOPING IN THE WIND
CORRIDOR AND IN THE CODY FOOTHILLS WHICH WILL LIKELY RESULT IN
EVENING LOWS AND THEN RISING TEMPERATURES. THE NEXT SYSTEM MOVES
DURING THE DAY FRIDAY ACROSS THE NORTH AND IN THE CENTRAL AND
SOUTH BY FRIDAY EVENING. SYSTEM MAY HAVE A LITTLE LESS MOISTURE TO
WORK WITH BUT POTENTIALLY STRONGER DYNAMICS WITH THE UPPER LOW
FORECAST TO BE CLOSER. HAVE INCREASED POPS SIGNIFICANTLY LATE
FRIDAY INTO FRIDAY NIGHT BUT THESE WILL LIKELY HAVE TO BE
INCREASED FURTHER OVER THE NEXT DAY. THIS SYSTEM LOOKS EVEN COLDER
THAN THE CURRENT SYSTEM WHICH SHOULD MAKE FOR A CHILLY FRIDAY
NIGHT UP NORTH IF IT CLEARS IN TIME AND THEN A VERY CHILLY EARLY
DECEMBER DAY ON SATURDAY.

.LONG TERM...SATURDAY NIGHT THROUGH WEDNESDAY
THE LONG TERM MODELS ARE IN DECENT AGREEMENT EARLY IN THE PERIOD AND
DIVERGE THEREAFTER. NOT MANY CHANGES WERE MADE TO THE PREVIOUS
FORECAST EXCEPT FOR THE INTRODUCTION OF SOME SLIGHT CHANCE POPS
LATER IN THE TERM TO ACCOUNT FOR THE SMALL POSSIBILITY OF ANOTHER
SYSTEM MOVING THROUGH...THOUGH CONFIDENCE IS VERY LOW AFTER THE
WEEKEND.

PREVIOUS LONG TERM DISCUSSION...
GLOBAL MODELS SHOW THE NORTHERN PORTION OF A SPLITTING TROUGH
PUSHING INTO THE PLAINS SATURDAY/SATURDAY NIGHT...WITH ANOTHER
SHORTWAVE DIVING SOUTH OUT OF CANADA INTO THE NORTHERN ROCKIES AND
NORTHERN PLAINS SUNDAY. PRECIPITATION WITH THE FIRST SYSTEM SHOULD
EXIT THE AREA SATURDAY...BUT CHANCES RETURN QUICKLY BY SUNDAY WITH
THE NEXT SYSTEM. WILL STILL HAVE RELATIVELY LOW POPS...WITH AN
EMPHASIS ALONG AND EAST OF THE DIVIDE. HOWEVER...THE MAIN IMPACT
FROM THE SYSTEM SUNDAY...WILL BRING YET ANOTHER REINFORCING SHOT OF
COLD CANADIAN AIR INTO THE FORECAST AREA.

DEEP AND DRY NORTHERLY FLOW WILL BE IN PLACE MONDAY...SO EXPECT
BELOW AVERAGE TEMPERATURES...BUT DRY CONDITIONS.

WARMER CONDITIONS ARE EXPECTED TUESDAY AND WEDNESDAY...AS THE UPPER
FLOW BACKS TO THE WEST/NORTHWEST...WITH MEDIUM RANGE MODELS
DIFFERING IF A TROUGH WILL DIG SOUTHEAST OUT OF BRITISH COLUMBIA
INTO THE NORTHERN ROCKIES TUESDAY NIGHT/WEDNESDAY. WILL KEEP THE
FORECAST MAINLY DRY FOR NOW...AND WAIT FOR BETTER MODEL CONTINUITY
BEFORE INTRODUCING AREA WIDE POPS.

.AVIATION.../00Z ISSUANCE/
WEATHER CONDITIONS WILL CONTINUE TO DETERIORATE ACROSS THE REGION
TONIGHT. AREAS OF MVFR/IFR CIGS AND VSBYS IN -SN WILL BE ENCOUNTERED
ACROSS MOST OF THE STATE WITH THE LOWEST CONDITIONS EXPECTED AS THE
FRONT PASSES BY AND ALONG AREAS NORTH OF MOUNTAIN RANGES...INCLUDING
CASPER MOUNTAIN. THE SURFACE PRESSURE GRADIENT WILL RAPIDLY
INTENSIFY AFTER 00Z THURS WITH STRONG N-NE WINDS AT 20-30KTS WITH
GUSTS TO 40 KTS PREVAILING ACROSS MOST AREAS...ALONG WITH AREAS
IFR/LIFR -SN BLSN VCNTY AND EAST OF A KEVW-KLND-KCOD LINE OVERNIGHT.
DRIER DOWNSLOPE NE WINDS WILL PREVAIL WEST OF THE DIVIDE AFTER 00Z
THUR WITH THE STRONGEST WINDS AND POSSIBLE MOUNTAIN WAVE ACTIVITY
EXPECTED ALONG THE WEST SLOPES OF THE WIND RIVER MTS...VCNTY KPNA.
VERY STRONG WINDS ARE ALSO EXPECTED VCNTY OWL CREEK MTS AS WELL.
CONDITIONS WILL BEGIN TO CLEAR IN THE WEST FIRST AFTER 02Z AND THEN
ACROSS THE NORTH...HOWEVER...WINDS WILL REMAIN STRONG THROUGH AT
LEAST 18Z THU IN THESE AREAS. THE SNOW WILL CLEAR ACROSS CENTRAL
WYOMING TOWARD THE END OF THE PERIOD.

.FIRE WEATHER...
A VERY STRONG CANADIAN COLD FRONT IS PUSHING RAPIDLY SOUTH ACROSS
THE DISTRICT LATE THIS AFTERNOON. THE RESULT WILL BE VERY STRONG
WINDS ACROSS MUCH OF THE AREA...LIGHT TO LOCALLY MODERATE SNOW AND
FALLING TEMPERATURES. BLOWING SNOW WILL ALSO CAUSE TRAVEL PROBLEMS
TONIGHT...ESPECIALLY IN JOHNSON...SWEETWATER AND SOUTHERN FREMONT
COUNTIES INCLUDING SOUTH PASS. THE WEATHER WILL IMPROVE ON
THURSDAY FROM NORTH TO SOUTH BUT IT WILL BE SHORT LIVED AS ANOTHER
