AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1134 PM MDT SUN JUN 23 2013

.SHORT TERM...TONIGHT THROUGH MONDAY

A PACIFIC TROUGH WILL BRING INCREASED CLOUDS TO THE SOUTH AND WEST
TONIGHT WITH INCREASING WINDS ACROSS THE SOUTH AND THROUGH THE WIND
CORRIDOR TO THE CASPER AREA.  TEMPERATURES WILL BE MILD TONIGHT.
MONDAY SOME SHOWERS AND ISOLATED THUNDERSTORMS WILL MOVE INTO THE WEST
AND MAY DEVELOP OVER THE HIGHER ELEVATIONS OF THE BIGHORN
MOUNTAINS. WINDS WILL PICK UP ACROSS THE AREA WITH VERY DRY CONDITIONS
AND HOT TEMPERATURES IN THE BASINS AND EASTERN PLAINS.

.LONG TERM...MONDAY NIGHT THROUGH SUNDAY

ANOTHER WELL DEFINED TROUGH WILL TRACK NORTHEAST ACROSS WYOMING
MONDAY NIGHT AND TUESDAY MORNING. THIS TROUGH WILL PRODUCE A GOOD
CHANCE OF THUNDERSTORMS ACROSS NW WYOMING MONDAY NIGHT AND
TUESDAY. LIKE WITH SATURDAYS TROUGH...THIS TROUGH WILL HAVE A
SIGNIFICANT AMOUNT OF Q VECTOR FORCING FOR A SUMMER FEATURE SO
SOME OF THESE THUNDERSTORMS COULD BE FAIRLY SIGNIFICANT. THE BEST
CAPES WILL BE IN THE FAR NORTH MONDAY NIGHT. IN THE
MEANTIME...FARTHER FROM THE DYNAMICS DIRECTLY ASSOCIATED WITH THIS
TROUGH...WEST SOUTHWEST WINDS WILL INCREASE OUT AHEAD OF THIS
APPROACHING TRAILING TROUGH FROM RKS TO RIVERTON TO BUFFALO
DRAWING IN HOT DRY DESERT AIR. THIS HAS PROMPTED THE ISSUANCE OF A
FIRE WEATHER WATCH FOR FIRE WEATHER ZONES 300...280 AND 285 FROM
18Z MONDAY THROUGH 03Z TUESDAY. THEN THE COMBINATION OF
INSTABILITY AND A TIGHT PRESSURE GRADIENT HAS PROMPTED PART TWO OF
THE FIRE WEATHER WATCH FOR THE SAME TIMES AND ZONES ON TUESDAY.
THEN FOR THE REST OF THE WEEK FOR THE FIRST TIME THIS YEAR...WE
TRULY GET INTO A SUMMERTIME PATTERN WITH THE NEXT PROMINENT
PACIFIC TROUGH BECOMING STATIONARY OFF THE PACIFIC COAST INSTEAD
OF PROGRESSIVELY TRACKING EAST ACROSS THE COUNTRY WHICH WILL ALLOW
THE HIGH PRESSURE AREA OVER TEXAS TO MIGRATE TO THE 4 CORNERS
AREA. BY THE END OF THE WEEK THE TYPICAL RING OF FIRE WILL DEVELOP
WITH THUNDERSTORMS BEGINNING TO ROTATE CLOCKWISE WITHIN THE OUTER
CIRCULATION OF THE HIGH PRESSURE AREA. SO BY NEXT SATURDAY AND
SUNDAY...THUNDERSTORMS SHOULD FORM MAINLY ON THE EAST SLOPE OF THE
NORTHERN MTNS WHERE A LIGHT SURFACE NORTHEAST UPSLOPE FLOW WILL
DEVELOP. HIGH TEMPERATURES WILL CLIMB WELL UP INTO THE 90S LATER
IN THE WEEK AS THE HIGH STRENGTHENS.

&&

.AVIATION.../06Z ISSUANCE/

SOUTHWEST FLOW ALOFT CONTINUES OVER WEST CENTRAL WYOMING THROUGH
MONDAY WITH DRY AND BREEZY CONDITIONS. SHOULD EVEN GET WINDY
ACROSS THE USUAL WIND PRONE AREAS BY MID AFTERNOON ON MONDAY.
OTHERWISE...VFR CONDITIONS WILL PREVAIL WITH A GRADUAL INCREASE IN
MID LEVEL MOISTURE. BY MONDAY EVENING...A FEW THUNDERSTORMS ARE
POSSIBLE OVER FAR WESTERN WYOMING INCLUDING YELLOWSTONE NATIONAL
PARK. GUSTY SURFACE WINDS WILL OCCUR NEAR ANY STORMS.

&&

.FIRE WEATHER...

FIRE WEATHER WATCH MONDAY AFTERNOON THROUGH TUESDAY EVENING ZONES 280...
285 AND 300.

TONIGHT WILL BE DRY AND MILD WITH BREEZY CONDITIONS. SOUTHWEST
WINDS WILL PICK UP ON MONDAY BECOMING WINDY ESPECIALLY ACROSS
SWEETWATER AND NATRONA COUNTIES. MANY AREAS WILL SEE RELATIVE
HUMIDITY AT 10 PERCENT OR LOWER IN THE AFTERNOON AND EARLY
EVENING. CLOUD WILL INCREASE ACROSS THE AREA WITH SHOWERS AND
ISOLATED THUNDERSTORMS IN THE WESTERN AND FAR NORTHERN MOUNTAINS.
