AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
300 PM MDT SAT SEP 8 2012

.SHORT TERM...TONIGHT THROUGH TUESDAY
CURRENT RIDGE ALOFT OVER WYOMING WILL FLATTEN BEGINNING SUNDAY.
THIS WILL ALLOW MOISTURE TO ADVECT INTO WYOMING LATE SUNDAY INTO
MONDAY. BEFORE ALL THIS HAPPENS...IT WILL BE CLEAR AND WARM THROUGH
SUNDAY. TEMPERATURES EAST OF THE CONTINENTAL DIVIDE SHOULD APPROACH
90 SUNDAY AFTERNOON. SUNDAY NIGHT TEMPS ALSO TO REMAIN WARM ACROSS
THE REGION.

AFOREMENTIONED MOISTURE SHOULD BRING SCT-BKN CLOUDS BY SUNDAY NIGHT
AND CONTINUE INTO MONDAY. MOST OF THIS EXPECTED TO BE MID LEVEL...BUT
WIDELY SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP BY MONDAY
AFTERNOON WITH POSSIBLY GREATER COVERAGE OVER FAR WEST AND
SOUTHWEST PARTS OF FORECAST AREA.

ATTENTION THEN TURNS TO NORTHERN STREAM TROUGH AND ASSOCIATED COLD
FRONT PUSHING ACROSS WEST CENTRAL WYOMING MONDAY NIGHT. THE TROUGH
WILL PUSH ANY LOW AND MID LEVEL MOISTURE MAINLY TO OUR EAST AND
SOUTH ON TUESDAY. CENTRAL AND NORTHERN LOCATIONS WILL CLEAR AND BE
QUITE COOL BEHIND THE FRONT. THE ONLY EXCEPTION LOOKS TO BE FAR
SOUTH...SWEETWATER COUNTY...WHERE MODELS DO HOLD ON TO SOME RELATIVE
HUMIDITY AND CLOUDS MONDAY NIGHT INTO TUESDAY. HOWEVER...BEST
MEASURABLE PRECIPITATION CHANCES TO BE OVER COLORADO ON TUESDAY.

RED FLAG WARNING WILL BE IN EFFECT FOR PARTS OF FORECAST AREA
BEGINNING SUNDAY AFTERNOON DUE TO WIND AND VERY LOW RELATIVE HUMIDITY.

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY
TUESDAY NIGHT...ISOLATED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE
ACROSS EXTREME SOUTHERN WYOMING.

WEDNESDAY THROUGH THURSDAY...COOLER TEMPERATURES ANTICIPATED
WEDNESDAY NIGHT THROUGH THURSDAY EVENING...WITH GENERALLY DRY
CONDITIONS.

FRIDAY THROUGH SATURDAY...WARMING TEMPERATURES WITH CONTINUED DRY
CONDITIONS.

MODELS IN FAIR AGREEMENT WITH THIS TIME FRAME. OUT OF THE MAIN
MODELS...THE GFS IS THE PRIMARY MODEL DEMONSTRATING THE SHOWER
ACTIVITY ACROSS THE SOUTHERN REACHES OF THE FORECAST AREA...THOUGH
THE EURO STILL INDICATES THE PRECIPITATION WILL GENERALLY STAY SOUTH
OF THE AREA...THOUGH WITHIN VERY CLOSE PROXIMITY OF THE BORDER. WITH
THE OPPORTUNITY PRESENT ITSELF...HAVE INCLUDED THESE WEAK SHOWERS
FOR WEDNESDAY NIGHT. HIGH PRESSURE THEN GENERALLY EXPECTED TO MOVE
INTO THE AREA WITH DRY CONDITIONS.

A STRONG AREA OF LOW PRESSURE MOVING ACROSS SOUTHERN CANADA WILL
SEND A SURGE OF COLDER TEMPERATURES ACROSS THE AREA WEDNESDAY AND
THURSDAY...ESPECIALLY IMPACTING WEDNESDAY NIGHT VALUES. THE EFFECTS
OF THIS SYSTEM WILL BE PRESENT THROUGH THURSDAY...WITH REBOUNDING
TEMPERATURES EXPECTED FRIDAY.

&&

.AVIATION.../00Z ISSUANCE/
VFR CONDITIONS ASSOCIATED WITH A HIGH PRESSURE SYSTEM EXPECTED TO
CONTINUE THROUGH SUNDAY AFTERNOON. LIGHT WIND OVERNIGHT MAY PERMIT
SMOKE TO SETTLE INTO THE BASINS...CREATING PERIODS OF MVFR
CONDITIONS. A DISTURBANCE WILL BEGIN TO MOVE INTO WESTERN WYOMING
SUNDAY AFTERNOON...WHICH MAY BRING SOME ISOLATED MOUNTAIN SHOWERS
DURING THE LATE AFTERNOON HOURS...WITH ASSOCIATED VCSH AT NEARBY
TERMINALS. MOST SHOWER ACTIVITY IS EXPECTED TO REMAIN OUT OF THE
BASINS UNTIL AFTER 00Z MONDAY.

&&

.FIRE WEATHER...
FIRE WEATHER CONCERNS WILL MAINLY OCCUR ON SUNDAY ACROSS WEST CENTRAL
WYOMING. INCREASING SOUTHWESTERLY FLOW ALOFT WILL RESULT IN BREEZY
CONDITIONS BY SUNDAY AFTERNOON. THE TRANSITIONING PATTERN AND WIND
FLOW WILL ALSO BRING LOW RELATIVE HUMIDITIES SUNDAY AFTERNOON AND
EVENING. MOST OF THE REGION WILL SEE HUMIDITIES DROP BELOW 15
PERCENT. WEATHER WILL REMAIN DRY THROUGH SUNDAY NIGHT.

MOIST SOUTHWEST FLOW AND DAYTIME HEATING ON MONDAY WILL AT LEAST
PRODUCE WIDELY SCATTERED SHOWERS AND THUNDERSTORMS...SPREADING ACROSS
THE SOUTH AND POTENTIALLY EAST DURING THE AFTERNOON. THERE COULD
BE SOME DRY LIGHTNING ASSOCIATED WITH THIS DEVELOPMENT...ESPECIALLY
OVER THE RAWLINS DISPATCH AREA AND POSSIBLY MOVING INTO THE WIND
RIVER MOUNTAINS. RELATIVE HUMIDITIES WILL ACTUALLY BE ON THE RISE
MONDAY INTO MONDAY NIGHT WITH AN APPROACHING COLD FRONT.
