NATIONAL WEATHER SERVICE RIVERTON WY
910 PM MDT MON AUG 22 2011

.UPDATE...
LET THE RED FLAG WARNINGS FOR ZONES 286 AND 288 EXPIRE AS WINDS HAVE
DIMINISHED AND THE RELATIVE HUMIDITY HAS DROPPED BELOW CRITICAL
LEVELS.

.SHORT TERM...TONIGHT THROUGH THURSDAY

RIDGE OVER THE CENTRAL AND SOUTHERN ROCKIES THIS AFTERNOON WITH A
SHORTWAVE MOVING THROUGH MONTANA.  SUBTROPICAL MOISTURE MOVING
THROUGH WYOMING IN THE FLOW WITH SOME ISOLATED THUNDERSTORMS OVER
THE SOUTHERN ABSAROKAS AND SOUTHERN BIGHORN BASIN AS OF 20Z.  CU
CONTINUES TO DEVELOP OVER THE CWA THIS AFTERNOON AND LOOKS LIKE
ANYWHERE COULD SEE A THUNDERSTORM POP OVERHEAD.  THEREFORE HAVE
ADDED ISOLATED THUNDERSTORMS TO MOST AREAS THIS EVENING...EXCEPT THE
FAR SOUTHWEST WHERE THERE IS A LACK OF INSTABILITY. GUSTY WINDS AND
LOW RHS HAVE PROMPTED THE ISSUANCE OF A RED FLAG WARNING THROUGH 9
PM FRO FIRE WEATHER ZONES 286 AND 288. PACIFIC TROUGH APPROACHES
TUESDAY MORNING AND MOVES ACROSS MONTANA DURING THE AFTERNOON AND
EVENING.  THIS WILL TIGHTEN THE GRADIENT PRODUCING A WEST SOUTHWEST
TO NORTHWEST GRADIENT WITH SPEEDS IN THE 15 TO 20 MPH WITH GUSTS OF
25-30MPH.  WILL ALSO SEE WELL ABOVE NORMAL TEMPERATURES AND VERY LOW
RH'S.  LOOKS LIKE A HIGH POTENTIAL FOR A RED FLAG EVENT TUESDAY
AFTERNOON AND EARLY EVENING FOR THOSE AREAS WITH CRITICAL FUELS.
THIS INCLUDES FWZ 280...281...283...285... 286...288 AND 300.  A
FRONT WILL MOVE THROUGH IN THE AFTERNOON AND EVENING SHIFTING THE
WINDS TO THE NORTH OVER JOHNSON AND NATRONA COUNTIES...AND NORTHWEST
OVER THE REMAINDER OF THE LOWER ELEVATIONS OF THE EAST AND WEST.
SO...WITH THE WINDS...LOW RH AND THE FRONTAL PASSAGE...WILL GO AHEAD
AND ISSUE A FIRE WATCH FOR THOSE FWZ LISTED ABOVE FROM NOON THROUGH
9 PM TUESDAY.  ENOUGH DRY AIR WILL BE IN PACE AND LITTLE IF ANY
INSTABILITY SO DO NOT EXPECT ANY CONVECTION.  SOUTHWEST FLOW AROUND
THE RIDGE RETURNS WEDNESDAY WITH SOME SUBTROPICAL MOISTURE BEGINNING
TO RETURN.  MOST OF THE AREA WILL BE STORM FREE...EXCEPT FOR
SOUTHWEST SWEETWATER COUNTY WHERE A FEW STORMS MAY MOVE OFF THE
UINTA MOUNTAINS.  OTHERWISE...IT REMAINS WARMER THAN NORMAL WITH
DIMINISHED WINDS.  WILL SEE WINDS BEGIN TO RETURN THURSDAY AS THE
NEXT PACIFIC SHORTWAVE MOVES INTO NORTHERN IDAHO AND WESTERN MONTANA
INCREASING THE GRADIENT.  THE SUBTROPICAL  MOISTURE SPREADS ACROSS
THE AREA...DEEPEST OVER THE WEST.  EXPECT TO SEE AT LEAST ISOLATED
THUNDERSTORMS THERE.  TEMPS REMAIN ABOVE NORMAL THURSDAY.

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY

PERSISTENT FOUR CORNERS UPPER RIDGE TO DOMINATE THE EXTENDED.
TEMPERATURES EXPECTED TO BE NEAR OR SLIGHTLY ABOVE NORMAL.
INGREDIENTS DO NOT SEEM TO COINCIDE EARLY IN THE EXTENDED FOR MUCH
CONVECTIVE ACTIVITY ALTHOUGH A FEW ISOLATED THUNDERSTORMS ARE NOT
OUT OF THE QUESTION FRIDAY AND SATURDAY.  DYNAMIC FORCING AND
MOISTURE REMAIN DISPLACED AS A PARADE OF SHORTWAVES WILL CONTINUE
ACROSS SOUTHERN CANADA AND SUBTROPICAL MOISTURE REMAINS TO THE
SOUTH...OCCASIONALLY BEING PUSHED INTO FAR SOUTHERN WYOMING BY
SOUTHWEST FLOW AROUND THE RIDGE.  MODELS TRY TO BRING A PACIFIC
SHORTWAVE FAR ENOUGH SOUTH TO TAP THE MONSOON AND BRING A GREATER
CHANCE OF THUNDERSTORMS FOR SUNDAY AND MONDAY BUT DISAGREE ON THE
TIMING AND MAGNITUDE OF THE DISTURBANCE.  THE ECMWF IS MORE BULLISH
WITH THE MOISTURE SO WIDESPREAD SHOWER ACTIVITY WOULD BE MORE LIKELY
ON MONDAY WITH THE EURO SOLUTION.

&&

.AVIATION...

VFR CONDITIONS WILL PREVAIL THROUGH THE NIGHT INTO TUESDAY.  PERIODS
OF MOUNTAIN OBSCURATION ARE POSSIBLE DUE TO SMOKE FROM KJAC TO
KU25.  AN ISOLATED SHOWER OR THUNDERSTORM IS POSSIBLE THROUGH 06Z VC
KRKS BUT ELSEWHERE DRY CONDITIONS ARE EXPECTED.  WESTERLY WIND WILL
SHIFT TO THE NORTHWEST AT 10-20KT BY 12Z AT KBYG AND KWRL AND BY 18Z AT
KCPR AS A WEAK FRONT PUSHES THOUGH.

&&

.FIRE WEATHER...

ISOLATED THUNDERSTORM ARE POSSIBLE ACROSS MUCH OF THE DISTRICT THIS
AFTERNOON AND EVENING AS A WEAK DISTURBANCE MOVES THROUGH.
LIGHTNING AND GUSTY OUTFLOWS WILL BE THE PRIMARY THREATS.  WILL ALSO
SEE SOME GUSTY WINDS THIS EVENING WITH RH'S BELOW 15%...ESPECIALLY
OVER THE WINDS AND ABSAROKAS.  HAVE ISSUED RED FLAG WARNING THROUGH
9 PM FOR 288 AND 286.  THOSE AREAS OVER MUCH OF THE SOUTHWEST WILL
EXPERIENCE THE WEATHER...BUT THEY DONT HAVE CRITICAL FUELS.  LOOKS
LIKE TUESDAY WILL BE AN ACTIVE FIRE WEATHER DAY.  AN APPROACHING
TROUGH WILL BRING GUSTY SOUTHWEST TO NORTHWEST WINDS TO MUCH OF THE
AREA ALONG WITH VERY LOW RH'S AND WARM TEMPERATURES.  A FRONT WILL
MOVE THROUGH IN THE AFTERNOON AND EVENING SHIFTING THE WINDS TO THE
NORTH OVER JOHNSON AND NATRONA COUNTIES...AND NORTHWEST OVER THE
REMAINDER OF THE LOWER ELEVATIONS OF THE EAST AND WEST.  WILL BE
ISSUING A FIRE WEATHER WATCH FOR THOSE ZONES WHERE FUELS ARE
CRITICAL. THIS INCLUDES FWZ 280...281...283...285...286...288 AND
300 FOR TUESDAY FROM NOON THROUGH 9 PM.  WEDNESDAY WILL SEE THE
WINDS DECREASE...THOUGH THE RH'S AND WARM TEMPERATURES CONTINUE.
THERE COULD BE AN ISOLATED THUNDERSTORM FORM OFF THE UINTAS.
ISOLATED THUNDERSTORMS RETURN OVER THE WEST ON THURSDAY.  WINDS WILL
BE ON THE INCREASE AS WELL AS A WEAK DISTURBANCE APPROACHES.
