AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
208 PM MDT FRI MAY 30 2014

.SHORT TERM...TONIGHT THROUGH SATURDAY

REMOTE SENSING SHOWING LARGE TROF TO THE WEST...LARGE RIDGE TO THE
EAST W/ OUT FA CAUGHT BETWEEN. SMALL SW CURRENTLY COMING INTO
SWRN/SRN PORTIONS OF THE CWA WILL HELP TO TRIGGER SHOWERS AND
THUNDER TODAY...ESPECIALLY OVER THE MOUNTAINS AND A NEARLY
STATIONARY FRONT DRAPED DOWN THE LEE SIDE OF THE ABSAROKAS...INTO T
HE WIND RIVER BASIN...THEN TO THE SOUTH AND INTO ERN SWEETWATER
COUNTY.

TODAY...UPR SW MOVING FROM S TO N ACROSS THE FA WILL COMBINE WITH
MODEST MOISTURE AND FORCING ALONG TERRAIN AND STATIONARY
FRONT/BOUNDARY TO GIVE ISOLATED TO SCATTERED SHOWERS AND THUNDER. ML
CAPE VALUES WILL RANGE FROM 500 TO 1000 J/KG OVR THE CENTRAL AND NRN
BASINS WHERE SOME MOISTURE POOLING HAS OCCURRED BEHIND A WEAK COLD
FRONT THAT PUSHED SWD OVERNIGHT. SHEAR WILL TEND TO BE MARGINAL AT
20 TO 25 KTS PLUS/MINUS...WITH STORM MOVEMENT FROM 15 TO 30 MPH MOST
AREAS...MUCH SLOWER MOVEMENT TO THE EAST IF STORMS CAN OCCUR...WHICH
WILL BE LESS LIKELY OVERALL WITH CAPPING IN PLACE...AND A LITTLE
FASTER IN THE NW ZONES. WILL HAVE TO WATCH FOR ANY TERRAIN TIED OR
AREAS THAT CONTINUALLY PRODUCE NEW CONVECTION FOR ENHANCED RAINFALL
AMOUNTS LOCALLY. OTHERWISE...NOT GENERALLY EXPECTING MUCH MORE THAN
A QUARTER OF AN INCH AT ANY ONE LOCATION. STRONG CONVECTION ENDING
BY EARLY EVENING...WITH SHOWERS LINGERING THRU MIDNIGHT IN SOME
PLACES. A FEW STRONGER STORMS CAN BE EXPECTED TODAY WITH MAINLY
STRONG WIND GUSTS AS  DCAPE RANGES BETWEEN 750 AND 1100 J/KG THIS
AFTERNOON...IN ADDITION TO SMALL/MARGINALLY SVR HAIL POSSIBLE.
BOUNDARY CRAWLERS OFF OF ADJACENT TERRAIN AND SFC FRONT/BOUNDARY
LIFTING NWD COULD PROVIDE AREAS OF ENHANCED VORTICITY AND A SMALL
CHANCE FOR AN ISOLATED WEAK TORNADO IN FAR EASTERN FREMONT OR
WESTERN NATRONA OR SERN WASHAKIE COUNTIES LATE THIS AFTERNOON OR
EARLY EVENING.

SATURDAY...SIMILAR SET-UP BUT WITH SLIGHTLY WARMER LL TEMPS...AND
THUS GREATER LL INSTABILITY...COMBINING WITH MORE ROBUST AND DEEP
DYNAMICS...ALL OCCURRING OVER A CONTINUING BUT MORE MOBILE SFC
FRONT/BOUNDARY ONCE AGAIN. UPR VORT MAX WILL HELP TO SPUR THIS ON
TOO BY LATE AFTERNOON. THIS TIME THE AREA OF CONCERN WILL RANGE FROM
CNTRL SWEETWATER COUNTY WHERE STRONG WIND MAKING THUNDERSTORMS WILL
BE LOCATED...TO THE NORTHEAST THROUGH ERN FREMONT AND ACROSS
NORTHERN NATRONA AND NORTH THROUGH JOHNSON COUNTY...WHERE CAPPING
WILL HOLD A BIT LONGER...BUT COMBINE WITH ML CAPE OF A THOUSAND OR
MORE J/KG AND 0-6KM SHEAR RUNNING 35 TO 40 KTS BY LATE AFTERNOON TO
PRODUCE MORE TYPICAL THUNDERSTORMS WITH A FEW SUPERCELLS POSSIBLE
ALONG WITH ALL THEIR ATTENDING SVR WX...INCLUDING LARGE
HAIL...STRONG DAMAGING WINDS AND EVEN A COUPLE OF TORNADOES. WILL
ALSO INCLUDE THE NORTHERN BIG HORN BASIN IN THIS MESS. CURRENT FCST
SFC BOUNDARY LOCATION LOOKS TO BE LOCATED FROM EXTREME NERN
SWEETWATER COUNTY OR SERN FREMONT COUNTY...NE INTO CNTRL
NATRONA...THEN NORTH THROUGH CENTRAL JOHNSON COUNTY...WITH ANOTHER
FRONT/BOUNDARY LOCATION INTO NRN BIG HORN BASIN AS THE NEXT COLD
FRONT BEGINS TO MAKE ITS WAY SWD BY LATE AFTERNOON. THIS WOULD BE
THE LOCATION TO EXPECT THE DAYS STRONGEST STORMS IN ADDITION TO THE
LOCATION OF POSSIBLE TORNADIC STORMS.

.LONG TERM...SATURDAY NIGHT THROUGH FRIDAY

SOUTH SOUTHWEST FLOW ALOFT WILL BE OVER WESTERN AND CENTRAL WYOMING
ON THE NORTHEAST SIDE OF AN UPPER LEVEL LOW CENTERED OVER THE
DESERT SOUTHWEST.  THE UPPER LEVEL FLOW WILL BE DIVERGENT PROVIDING
UPPER LEVEL SUPPORT FOR VERTICAL LIFT WHICH WILL BE IN COMBINATION
WITH THERMAL HEATING IN THE EARLY EVENING HOURS.  SCATTERED SHOWERS
AND ISOLATED THUNDERSTORMS WITH SMALL HAIL AND STRONG WIND GUSTS
WILL BE OVER THE AREA AND MOST NUMEROUS IN THE MOUNTAINS AND EAST
WHERE BETTER LOW LEVEL MOISTURE WILL BE AVAILABLE.  THE SOUTHWEST
WILL BE ON THE DRY SIDE IN THE LOWER LEVELS SUPPORTING STRONG DRY
MICROBURST WINDS. CONVECTION WILL DECREASE RAPIDLY THROUGH LATE
EVENING BUT SOME SHOWERS WILL LINGER OVER THE MOUNTAINS AND EAST
OVERNIGHT.  DO NOT EXPECT MUCH CHANGE IN OVERNIGHT LOW TEMPERATURES
WITH SLIGHT WARMING.  A PACIFIC UPPER LEVEL TROUGH WILL APPROACH THE
WEST OVER WESTERN MONTANA EXTENDING SOUTHWEST INTO SOUTH CENTRAL
IDAHO AND NORTHERN NEVADA.  THIS PACIFIC TROUGH WILL BE THE KICKER
TO EJECT THE SOUTHWEST LOW EAST INTO WESTERN NEW MEXICO AND
EVENTUALLY CUT OFF THE MOISTURE ADVECTION FROM THE SOUTH SUNDAY
THIS WILL BRING A PATTERN CHANGE WITH A SERIES OF PACIFIC TROUGHS IN
WESTERLY FLOW THAT WILL SET UP OVER WESTERN AND CENTRAL WYOMING.
THIS WILL SHIFT THE THREAT OF SHOWERS AND THUNDERSTORMS INTO THE
WEST AND NORTH WITH DECREASED ACTIVITY IN THE SOUTH AND EAST.
TEMPERATURES WILL COOL SUNDAY WITH A COLD FRONT MOVING SOUTH FROM
MONTANA SUNDAY MORNING CONTINUING THROUGH THE DAY. CONVECTION WILL
DECREASE AS THE FIRST PACIFIC TROUGH MOVES EAST INTO THE NORTHERN
HIGH PLAINS AND WEAK RIDGING ALOFT OCCURS.  THIS WILL BE BRIEF WITH
ANOTHER PACIFIC TROUGH MOVING INLAND INTO THE PACIFIC NORTHWEST
MONDAY NIGHT.  THIS TROUGH WILL MOVE INTO THE NORTHERN ROCKIES AND
NORTHERN GREAT BASIN INTO WESTERN WYOMING ON TUESDAY WITH MORE
SHOWERS AND THUNDERSTORMS IN THE WEST.  EXPECT TO SEE INCREASING
SOUTHWEST LOW LEVEL FLOW WITH WARMING AND DRYING. THEN COOLING IS
LIKELY ON WEDNESDAY AS ANOTHER COLD FRONT MOVES SOUTH. AFTER WEDNESDAY
PATTERN BECOMES REDUNDANT WITH AFTERNOON AND EVENING CONVECTION
AND SLIGHT WARMING.
