AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
354 PM MDT TUE JUN 24 2014

.SHORT TERM...TONIGHT THROUGH WEDNESDAY

WV IMAGERY SHOWING RIDGE AXIS OVER THE WRN BORDER OF WY...TROFFING
EAST WITH EMBEDDED SW/WEAK JET STREAK EXITING EWD...A WEAK VORT MAX
CRESTING THE RIDGE NOW...AND ANOTHER SW/JET OVR THE GREAT BASIN. AT
THE SFC...LOW P STILL OF THE SW...HIGH(ER) PRESSURE OFF TO THE NE
ACROSS THE NRN PLAINS...WITH THREE WEAK BOUNDARIES ACROSS THE
CWA...ONE ACTING LIKE A VERY WEAK FRONT AND STILL DRAPED ALONG THE
ERN SLOPES OF THE MOUNTAINS E OF THE DIVIDE. THE OTHERS ARE
ASSOCIATED W/ THE SW LOW...WITH WEAK INVERTED LOBES STRETCHING TO
THE N ALONG OUR WRN BORDER WITH ID...AND THE OTHER POINTED EWD
ACROSS SWEETWATER COUNTY INTO ERN FREMONT AND THEN E INTO NATRONA
COUNTY. THIS SET-UP OFFERS UP A FEW DIFFERING CONVERGENCE ZONES IN
ADDITION TO THE MOUNTAINS. ERLY FLOW E AND N OF THE SOUTHERN
BOUNDARY...WESTERLY/SOUTHWESTERLY TO THE WEST AND SOUTH OF THE
BOUNDARY. HIGHER CAPE WILL ONCE AGAIN SHOWING ALONG AND N OF THIS
BOUNDARY IN THE MORE ERLY FLOW...GIVING SOME ADDITIONAL FOCUS AND
STRENGTH TO POSSIBLE STORM INITIATION THIS AFTERNOON...ALONG WITH
THOSE THAT MAKE IT OFF FROM THE MOUNTAINS. ADDITIONALLY...THE WEAK
RIDGE RUNNING SW WILL RIDE OVR THE FA BY MID-DAY...HELPING TO SPARK
EARLIER CONVECTION EVEN AS HEIGHTS ARE ON THE RISE. ATTM...STORM
PARAMETERS LOOK TO REMAIN MOSTLY AOB SEVERE LEVELS. HOWEVER STRONGER
STORMS AND ISOLATED SVR MAY STRETCH ALONG/NORTH OF THE SOUTHERN SFC
BOUNDARY AND A BIT FURTHER INTO THE CENTRAL CWA TODAY WITH 0-6 KM
SHEAR HOVERING BETWEEN 20 AND 30 KTS...INCREASING SOMEWHAT EARLY
THIS EVENING AND OVERNIGHT. CIRRUS CLOUD SHIELD MOVING ACROSS THE FA FROM
WEST TO EAST IS CURRENTLY KEEPING MUCH OF THE REGION W OF THE DIVIDE
UNDER CONTROL EARLY. BIG HORNS CURRENTLY CAPPED BUT IN SUNSHINE WILL
LIKELY GO LATER AFTER THE SRN ABSAROKAS WHICH ARE LESS CAPPED...THEN
PORTIONS OF THE SFC BOUNDARY OVR SWEETWATER AND SUBLETTE COUNTIES
NEXT. WILL HAVE TO WATCH FOR OPENING IN THE SHIELD FOR CI TO OCCUR
ELSEWHERE. THIS MAY ALSO KEEP SFC HIGHS FROM REACHING FCST LVLS...OR
MAY OCCUR RATHER LATE IF THEY DO.

WED BEGINS WITH UPR RIDGE CENTERED OVR WY WITH GREAT BASIN LOW
BUILDING INTO SWRN WY...WITH A KINDA/SORTA WARM FRONT/INVERTED TROF
EXTENDING TO THE NE THEN N ALONG THE BIG HORNS. THIS WILL OPEN THE
DOOR TO SERLY LL FLOW THROUGH AT LEAST NRN NATRONA COUNTY AND ALL OF
JOHNSON COUNTY...WITH DECENT MOISTURE RETURN THRU AT LEAST THE
MORNING PERIOD...POSSIBLY INTO THE EARLY AFTERNOON. AS A WEAK RIDGE
RUNNING SW/JET STREAK MOVES ACROSS THE AREA IN THE AFTERNOON...AT
LEAST ISOLATED CONVECTION WILL OCCUR ALONG/NEAR TROF/FRONT/BOUNDARY
N OF THE SFC LOW ALONG WITH WHAT CAN GO OVR THE BIG HORNS. PLACEMENT
OF THE TROF/FRONT/BOUNDARY WILL MEAN EVERYTHING AT THIS TIME...WITH
MOST SEVERE WEATHER OCCURRING ALONG/EAST OF THE BOUNDARY WHERE CAPE
RANGING FROM 1200 TO 2000 J/KG AND DEEP SHEAR WILL BE MAXIMIZED IN
OUR FA FOR A SHORT TIME BEFORE GETTING SQUEEZED OUT ACROSS THE ERN
BORDER. A LITTLE OF EVERYTHING COULD OCCUR...INCLUDING LARGE
HAIL...DAMAGING WINDS...AND/OR AND ISOLATED TORNADO...ESPECIALLY
ALONG THE BOUNDARY WHERE SOME SFC BACKING OF THE WINDS IS EXPECTED
UNTIL A FRONT MOVES SOUTH ACROSS THE ERN COUNTIES IN RESPONSE TO
MID/UPR FORCING AND THE RETREAT OF THE SW SFC LOW AND ANY DEVELOPING
LEE LOW IN CO.

.LONG TERM...WEDNESDAY NIGHT THROUGH TUESDAY

A CLOSED LOW OFF THE BRITISH COLUMBIA COAST WILL SWING A VORT LOBE
THROUGH THE AREA WEDNESDAY EVENING. THIS WILL BE THE FIRST IN A
SERIES OF SHORTWAVE TROUGHS THAT WILL ROTATE AROUND THIS PARENT
LOW THROUGH SATURDAY. SCATTERED THUNDERSTORMS WILL CONTINUE
THROUGH MUCH OF THE EVENING WEDNESDAY NIGHT FROM THIS VORT LOBE
ALONG WITH A CHANCE OF STRONG THUNDERSTORMS JOHNSON AND NATRONA
COUNTIES WHERE THE BEST CAPE WILL BE. THURSDAY WILL BE A REPEAT
OF WEDNESDAY BUT THE SEVERE THREAT WILL BE MAINLY OVER NORTHEAST
BIG HORN AND JOHNSON COUNTIES LATE THURSDAY WITH THE NEXT
SHORTWAVE. THURSDAY SHOULD SEE THE STRONGEST SOUTHWEST BREEZES
ACROSS THE CWA AS THE SFC GRADIENT TIGHTENS A BIT. WE WILL
CONTINUE WITH THE SHORTWAVES ROTATING THROUGH EVERY 24 HOURS
THROUGH SATURDAY. HOWEVER A CLOSED LOW WILL ESTABLISH ITSELF
NORTH OF THE CENTRAL MONTANA CANADIAN BORDER WITH THE ASSOCIATED
MAIN TROUGH AXIS APPROACHING THE ROCKIES WHICH WILL PRODUCE MORE
NUMEROUS MAINLY LATE DAY SHOWERS AND THUNDERSTORMS AND CLOUDS
WHICH WILL COOL TEMPS DOWN BY AROUND 5 TO 10 DEGREES BY FRIDAY. ON
SATURDAY NIGHT THE MAIN TROUGH WILL TRACK ACROSS THE REGION FOR
THE COOLEST WEATHER OF THE WEEK TO OCCUR SUNDAY BEHIND THE TROUGH
AXIS BUT NOT AS COOL AS TEMPS WERE TWO WEEKENDS AGO. THE THREAT
OF LATE DAY T STORMS WILL CONTINUE THROUGH SUNDAY AND MONDAY WITH
A WEAK SHORT LIVED COOL FRONT DUE THROUGH THE AREA MONDAY. NEXT
TUESDAY SHOULD FEATURE THE LEAST LIKELY DAY FOR ANY SHOWERS AS A
RIDGE BUILDS IN WITH CONFLUENT FLOW.

FOR THE SOUTHERN DISPATCH ZONES WHICH WILL NOT HAVE MUCH OF A
CHANCE FOR PRECIPITATION. WINDS WILL COME AROUND TO THE

DURING THE DAY. STRONGER GUSTY WEST WINDS WILL LAY ACROSS THE
SOUTHERN ZONES 277 278 279 AND 289 WHERE WHERE IN COMBINATION WITH
