AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1138 AM MDT WED AUG 15 2012

.SHORT TERM...WEDNESDAY THROUGH FRIDAY NIGHT

A STRONG COLD FRONT THAT WILL USHER IN SOME OF THE COOLEST AIR SINCE
SPRING IS NOW MAKING ITS WAY THROUGH SOUTHERN MONTANA AND WILL ENTER
NORTHERN WYOMING AROUND 8Z. A PUSH OF STRONG WINDS MOVED THROUGH
MONTANA WITH GUSTS TO 60 MPH. PRESSURE RISES HAVE DROPPED BUT WE
STILL ANTICIPATE SOME WIND GUSTS POSSIBLY AS HIGH AS 50 MPH AS THE
FRONT MOVES INTO NORTHERN WYOMING. THE FRONT WILL CONTINUE TO
DRIVE SOUTHWARD THROUGH THE DAY REACHING SOUTHERN WYOMING BY
MORNING. ONE QUESTION IS HOW MUCH PRECIPITATION WILL FALL. THE
BEST DYNAMICS STILL LOOK TO MOVE NORTH OF THE AREA SO ANY
PRECIPITATION OUTSIDE OF OROGRAPHICALLY ENHANCED AREA WILL LIKELY
BE SPOTTY. THE HIGHEST POPS WILL BE OVER THE BIGHORNS AND EAST AS
WELL AS UPSLOPE AREAS OF THE ABSAROKAS AND WIND RIVER RANGE.
ANOTHER QUESTION WILL BE FOR POSSIBLE THUNDERSTORMS. SPC HAS THE
WHOLE STATE UNDER A GENERAL AREA. HOWEVER...THERE IS NOT A LOT OF
CAPE EXCEPT OVER SOUTHERN WYOMING AND SOME MOUNTAINS. FOR NOW WE
HAVE LEFT ISOLATED THUNDERSTORMS IN THE FORECAST ALTHOUGH THE
CHANCE IS VERY MINIMAL IN NORTHERN WYOMING WHERE COOL AIR WILL
MOVE IN AND AN INVERSION SETS UP. THE NEXT DILEMMA IS FOR
TEMPERATURES ACROSS THE AREA. THESE WILL BE A PAIN IN THE NECK TO
SAY THE LEAST. WITH THE FRONT ARRIVING EARLY IN THE NORTH...EXPECT
ONLY 60S IN PLACES LIKE CODY AND BUFFALO WITH SOME AREAS STAYING
IN THE 50S. MEANWHILE...AREAS IN SWEETWATER COUNTY WILL SEE HIGHS
INTO THE 80S. THE TOUGH AREAS WILL BE PLACES LIKE CASPER AND
RIVERTON. FOR NOW WE HAVE PLAYED THE MIDDLE GROUND WITH HIGHS IN
THE 70S. ALSO...WITH THE LATE ARRIVAL OF THE FRONT IN SOUTHERN
WYOMING AND GUSTY WINDS AHEAD OF THE FRONT...A RED FLAG WARNING
HAS BEEN ISSUED FOR THIS AFTERNOON.

THE CHANCE OF SHOWERS SHOULD TAPER OFF LATER TONIGHT AS THE FRONT
PUSHES OUT OF THE AREA WITH MOST AREAS DRY BY MORNING. THE
EXCEPTIONS WILL BE THE FAVORED UPSLOPE AREAS WITH EAST AND NORTHEAST
FLOW WHERE SHOWERS WILL BE A BIT MORE NUMEROUS. WITH 700 MB
TEMPERATURES FALLING INTO THE 30S...AN INCH OR TWO OF SNOW
ACCUMULATION IS POSSIBLE ABOVE 10000 FEET. HOWEVER...NO TRAVEL
PROBLEMS ARE EXPECTED WITH ANY ACCUMULATING SNOW TO BE ABOVE PASS
LEVEL.

THE MAIN PROBLEM FOR THURSDAY WILL BE TEMPERATURES EAST OF THE
DIVIDE. A LOT DEPENDS ON HOW QUICKLY CLOUD COVER CAN MOVE OUT. MOST
MODELS CLEAR OUT THE CLOUDS FOR THE AFTERNOON BUT IT STILL LOOKS
RATHER COOL WITH 70S IN MOST AREAS EAST OF THE DIVIDE WITH SOME 60S
STILL POSSIBLE IN JOHNSON COUNTY. MEANWHILE...WEST OF THE DIVIDE
EXPECT MAINLY DRY WEATHER WITH TEMPERATURES CLOSE TO NORMAL. A
SPOTTY SHOWER OR THUNDERSTORM MAY DEVELOP IN THE AFTERNOON OVER THE
ABSAROKAS WITH WEAK EASTERLY UPSLOPE FLOW...BUT THESE LOOK TO BE FEW
AND FAR BETWEEN AT THIS POINT.

A WARMING TREND THEN LOOKS TO BEGIN FOR FRIDAY AS RIDGING BEGINS TO
BUILD IN AGAIN FROM THE WEST AND FLOW TURNS TO MORE OF A WESTERLY
DIRECTION. A BIT OF MOISTURE RETURNING MAY BRING A FEW HIGHER
ELEVATION THUNDERSTORMS BUT NOTHING WIDESPREAD. EXPECT HIGH
TEMPERATURES TO REACH NEAR NORMAL LEVELS FOR MOST OF THE REGION.

.LONG TERM...SATURDAY THROUGH WEDNESDAY

MEDIUM RANGE GLOBAL MODELS BEGIN THE EXTENDED PERIOD IN OVERALL GOOD
AGREEMENT ON SATURDAY WITH AMPLIFIED UPPER RIDGE OVER THE
INTERMOUNTAIN WEST...A DRY LIGHT NORTHERLY FLOW ACROSS CENTRAL AND
EASTERN WYOMING.  THIS PATTERN WILL KEEP TEMPERATURES NEAR OR BELOW
NORMAL EAST OF THE DIVIDE...MAINLY IN THE 75 TO 85 DEGREE RANGE.

MODEL SOLUTIONS BEGIN TO DIVERGE ON SUNDAY...MAINLY INVOLVING THE
HANDLING OF SHORTWAVES EJECTING FROM EASTERN PACIFIC TROUGH
RESULTING IN THE FLATTENING OF DOWNSTREAM RIDGE.  BOTH ECMWF AND GFS
FLATTEN RIDGE OVER INTERMOUNTAIN WEST BY 12Z MONDAY.  GFS SHOWS MORE
PROGRESSION OF UPPER HIGH INTO SOUTHERN ROCKIES BY 12Z WEDNESDAY AS
EASTERN PACIFIC TROUGH MAKES LANDFALL IN NORTHERN CALIFORNIA.  ECMWF
BRINGS SHORTWAVE OVER TOP OF RIDGE...DIVING SHORTWAVE SOUTH ACROSS
WYOMING ON TUESDAY.  THERE IS LITTLE CONFIDENCE IN EITHER OF THESE
SOLUTIONS.

TEMPERATURES WILL RETURN TO NEAR 90 ACROSS THE CENTRAL BASINS ON
SUNDAY...AND THEN A FEW DEGREES WARMER ON MONDAY.  ECMWF AND GFS DO
AGREE ON ROTATING SOME HIGH LEVEL MONSOONAL MOISTURE INTO THE
WEST ON SUNDAY AND ACROSS WYOMING ON MONDAY AND TUESDAY. FORECAST
KEEPS SLIGHT CHANCES OF THUNDERSTORMS CONFINED TO THE WEST SUNDAY
AND MONDAY...SPREADING INTO CENTRAL AREAS ON TUESDAY.

&&

.AVIATION.../18Z ISSUANCE/

COLD FRONT HAS PUSHED AS FAR SOUTH AS THE WIND RIVER RANGE AND GREEN
MOUNTAINS AS OF LATE MORNING. NORTHERLY WINDS HAVE NOT BEEN AS
STRONG OR PERSISTENT AS WAS EARLIER EXPECTED. HAVE BACKED OFF WINDS
BEHIND THE FRONT FOR TERMINALS EAST OF THE DIVIDE. BKN CLOUD DECKS
FROM 020-040 MSL HAVE DEVELOPED IN THE WESTERN BIG HORN BASIN AND IN
JOHNSON COUNTY. MOUNTAIN TOP OBSCURATIONS ABOVE 080 MSL WILL BE
FREQUENT THROUGH THE OVERNIGHT HOURS. KCPR AND KCOD WILL BE THE MOST
LIKE LOCATIONS TO SEE MVFR THIS AFTERNOON AND TONIGHT. FRONTAL PUSH
THROUGH KRKS SHOULD COME BETWEEN 23Z/WED AND 02Z/THU WITH GUSTY
EAST-NORTHEAST WIND BEHIND THE FRONT. KPNA AND KBPI COULD BRIEFLY
SEE SOUTHEAST WIND LATE TONIGHT BUT KJAC WEST OF THE DIVIDE WILL SEE
NOTHING MORE THAN ENHANCED NORTHERLY DRAINAGE FLOW AFTER SUNSET.
REDUCED VISIBILITY DUE TO SMOKE MOST LIKELY TO BE AN ISSUE AT
KJAC...KPNA... KBPI AND KAFO WHERE WIND DIRECTION AND SPEED ARE NOT
FAVORABLE FOR SCOURING OUT THE WESTERN WILDFIRE SMOKE. EVEN WITH THE
SMOKE AT THESE LOCATIONS THESE TERMINALS WILL BE VFR THROUGH THE
PERIOD. LOWER VFR CLOUD DECKS SHOULD DISSIPATE BETWEEN 14Z-17Z/THU
AS NEAR SURFACE LAYER WARMS AND DRIES AND UPSLOPE FLOW WEAKENS.

&&

.FIRE WEATHER...

A COLD FRONT WILL DROP SOUTHWARD THROUGH THE STATE FROM NORTH TO
SOUTH EAST OF THE DIVIDE TODAY. A PERIOD OF GUSTY WINDS WILL
ACCOMPANY THE PASSAGE AS WINDS TURN FROM THE WEST TO THE NORTH AND
NORTHEAST. THE FRONT WILL USHER IN COOLER TEMPERATURES AND HIGHER
HUMIDITY FOR AREAS FROM THE WIND RIVER RANGE AND GREEN MOUNTAINS AND
NORTHWARD TODAY ALONG WITH SPOTTY SHOWERS AND THUNDERSTORMS. ACROSS
SOUTHERN WYOMING...EXPECT ANOTHER WARM AND BREEZY DAY WITH LOW
RELATIVE HUMIDITY. AS A RESULT...A RED FLAG WARNING HAS BEEN ISSUED
FOR THAT AREA. PLEASE SEE THE FIRE WEATHER PRODUCTS FOR DETAILS. A
WETTING RAIN AND POSSIBLE SOME HIGHER ELEVATION SNOW MAY FALL ACROSS
THE ABSAROKAS...WIND RIVER RANGE AND ESPECIALLY THE BIGHORNS THIS
AFTERNOON AND TONIGHT. HIGH PRESSURE WILL BUILD OVER THE AREA FOR
THURSDAY AND BRING INCREASING SUNSHINE ALONG WITH LIGHT WINDS.
TEMPERATURES WILL REMAIN BELOW NORMAL EAST OF THE DIVIDE AND NEAR
NORMAL WEST OF THE DIVIDE.
