AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
417 PM MDT TUE MAY 27 2014

.SHORT TERM...TONIGHT THROUGH WEDNESDAY
THE BAND OF THUNDERSTORMS THAT TRACKED EAST ACROSS SWEETWATER COUNTY
HAS JUST ABOUT CROSSED OVER THE BORDER INTO CARBON COUNTY.
IN THE MEAN TIME...OTHER CONVECTION HAS FORMED OVER THE SOUTHERN ABSORKA
AND OWL CREEK MTNS. ANY STORMS THAT FORM WILL LIKELY STRENGTHEN
AS THEY PROPOGATE EAST NORTHEAST INTO JUICIER AIR. DEW POINTS WEST
OF THE DIVIDE ARE ONLY IN THE TEENS AND 20S WITH 30S AND 40S EAST
ALONG WITH A 52 DP AT BYG. HOWEVER...THE AIR MASS IS STILL LIKELY
CAPPED IN THE NORTHEAST ZONES SO AFTER THE CELLS GROW...THEY WILL'
EVENTUALLY DIE OFF AS THEY APPROACH JOHNSON COUNTY UNLESS THE CAP IS
BROKEN. THE STORM DEVELOPMENT SHOULD FAVOR THE NORTHEAST BOUND DRY LINE.

THE GFS APPEARS MORE REPRESENTATIVE AS TO WHAT WILL ACTUALLY OCCUR
WEDNESDAY AS THE CIRCULATION OFF THE PACIFIC NORTHWEST COAST MOVES
INLAND AND THE STEERING FLOW BACKS AND TIGHTENS. HOWEVER...THIS
SOUTH FLOW WILL USHER IN EVEN HOTTER AND DRIER CONDITIONS WITH
MANY LOCATIONS WITNESSING LOW 90S EAST OF THE DIVIDE. TEMPS TODAY
ARE ALREADY WARMER THAN THEY HAVE BEEN ALL SEASON IN SOME AREAS.
WE WILL LIKELY FLIRT WITH NEAR RECORD TEMPS AT CPR...RIW...LND AND
WRL WEDNESDAY AS H7 TEMPS APPROACH 15C. THE RH WILL DIP TO THE
UPPER SINGLE DIGITS IN SWEETWATER COUNTY WEDNESDAY. SOUTHWEST
WINDS WILL INCREASE OVER MUCH OF THE CWA WITH THESE SFC WINDS
EFFECTIVELY LOWERING THE DP AND RAISING TEMPS. THIS WILL TURN OUT
TO BE A PHANTOM CRITICAL FIRE WEATHER DAY AS FUELS REMAIN NON
CRITICAL. THE...NAM ON THE OTHER HAND...IS HINTING AT MORE OF A
SCENARIO THAT INVOLVES A COOLER AND MORE MOIST VERSION OF
WEDNESDAYS WX WITH HIGHER POPS BUT WILL THROW THIS IDEA OUT BASED
ON THE AFOREMENTIONED SYNOPSIS.

.LONG TERM...WEDNESDAY NIGHT THROUGH TUESDAY
RIPPLES IN THE SW FLOW WITH A GRADUAL INCREASE IN MID LEVEL MOISTURE
FROM THE SOUTH WILL BE THE MAIN WEATHER STORY FOR THE SOUTH. THE LOW
LEVELS WILL BE DRY WITH BREEZY TO WINDY CONDITIONS. ISOLATED HIGH
BASED SHOWERS OR ISOLATED THUNDERSTORMS ARE POSSIBLE WEDNESDAY NIGHT
AND THURSDAY. A FEW OF THE HIGHER BASED STORMS THURSDAY AFTERNOON
MAY PRODUCE 50 MPH WIND GUSTS OR MORE...OTHERWISE IT WILL JUST BE A
WARM AND WINDY DAY. FURTHER NORTH...A COLD FRONT WILL TRY AND PUSH
SOUTH INTO AT LEAST THE NORTHERN ZONES LATER WEDNESDAY NIGHT INTO
THURSDAY MORNING. HOW FAR SOUTH THIS FRONT CAN MAKE IT THURSDAY IS
IN QUESTION. THE NAM PUSHES IT ALL THE WAY TO THE CONTINENTAL DIVIDE
WHILE THE GFS KEEPS IT IN THE FAR NRN ZONES. FOR NOW...I'M KEEPING
IT TO THE NRN THIRD OF THE AREA DURING THE DAY THURSDAY BEFORE IT
MAKES A PUSH SOUTH THURSDAY NIGHT. A FEW STRONGER STORMS MAY DEVELOP
ALONG THE FRONT ON THURSDAY. BEHIND THE FRONT...IT WILL BE MORE
STABLE SO ANY CONVECTION MAY BECOME ELEVATED AS IT MOVES NE FROM THE
MORE UNSTABLE AIR SOUTH OF AND ALONG THE COLD FRONT TO NORTH OF THE
COLD FRONT. ISOLATED SHOWERS COULD LINGER JUST ABOUT ANYWHERE
THURSDAY NIGHT WITH WEAK RIPPLES AND A MODEST AMOUNT OF MID LEVEL
FLOW FROM THE S AND SW. ON FRIDAY...SOME DAY 2 OR RETURN FLOW
MOISTURE MAY OCCUR IN THE ERN ZONES WHERE SE FLOW IS POSSIBLE
BRINGING IN SOME UPPER 40S TO LOWER 50 DEW POINTS INTO THE ERN
ZONES. DEPENDING ON THE AMOUNT OF HEATING AND THE EXACT DEW
POINT...THE FORECAST SOUNDINGS SHOW SOME CAPES IN EXCESS OF 1000J/KG
IN JOHNSON AND NATRONA COUNTIES FRIDAY AFTERNOON. LATER SHIFTS CAN
WATCH THIS EVOLUTION. TEMPERATURES WILL BE QUITE TRICKY ON THURSDAY
WITH CONSIDERABLY COOLER CONDITIONS NORTH OF THE FRONT AND QUITE
WARM STILL SOUTH. THE FRONT MAY LIFT OR WASH OUT BY SATURDAY BUT A
STREAM OF MID LEVEL MOISTURE FROM THE SOUTH WILL KEEP WIDELY
SCATTERED TO SCATTERED AT LEAST HIGHER BASED STORMS GOING WITH THE
FAR NORTH POTENTIALLY SEEING A FEW STRONGER STORMS. AS THE NEXT
UPPER LOW FORMS AND MOVES INTO THE GREAT BASIN ON SUNDAY...THE SOUTH
MAY SEE SOME DRIER AIR IN THE MID TO LOWER LEVELS MOVE IN WHILE A
FRONTAL BOUNDARY HANGS ACROSS THE NORTH ALONG WITH POTENTIAL BETTER
LIFT. THE WHOLE AREA THOUGH MAY AT LEAST BE IN GENERAL ASCENT AHEAD
OF THIS CLOSED UPPER LOW. POTENTIAL FOR ISOLATED SHOWERS AND
THUNDERSTORMS WILL EXIST EVEN AT NIGHT WITH THE OBVIOUS INCREASE
DURING THE AFTERNOON HOURS. GFS SHOWS THE LOW WEAKENING AND MOVING
TO OUR NORTH ON MONDAY WITH DECENT MOISTURE BUT LESS INSTABILITY. A
GOOD CHANCES OF SHOWERS AND ISOLATED THUNDERSTORMS LOOKS GOOD FOR
THE NORTH WITH A GENERALLY DRY AND WINDY SOUTH. IF THE LOW IS A
LITTLE FURTHER SOUTH LIKE THE ECMWF THEN SUNDAY AND MONDAY COULD BE
MUCH MORE ACTIVE ACROSS MORE OF THE AREA...ESPECIALLY THE NORTHERN
TWO THIRDS. HEIGHTS REBUILD ON TUESDAY AHEAD OF ANOTHER POTENTIAL UPPER
LOW MOVING INTO THE WESTERN PART OF THE U.S. COULD SEE THE FRONTAL
BOUNDARY HANGING ACROSS THE NORTH WITH SOME LATE DAY FORCING IN THE
NWRN CORNER. MORE ISOLATED COVERAGE AT BEST IN THE FAR SOUTH EXCEPT
DOWNWIND OF THE NEARBY MOUNTAIN RANGES.

.AVIATION.../00Z ISSUANCE/

EAST OF THE DIVIDE...KCOD/KCPR/KLND/KRIW/KWRL ROUTES

A SURFACE COLD FRONT WILL STALL OUT ALONG THE CONTINENTAL DIVIDE AND
BEGIN TO RETREAT NE AS A DRIER SOUTHWEST FLOW PUSHES INTO CENTRAL
WYOMING THIS EVENING. ISOLATED SHOWERS AND THUNDERSTORMS WILL FORM ALONG
THIS RETREATING BOUNDARY MAINLY VCNTY AND SOUTH OF A 50NE RKS-KCPR
LINE WITH THE ATMOSPHERE LIKELY REMAINING MORE CAPPED TO THE
NORTH. THUNDERSTORMS WILL DIMINISH OR MOVE EAST OUT OF THE AREA BY
04Z WEDNESDAY LEAVING MAINLY CLEAR SKIES AND GENERALLY LIGHT WIND.

WEST OF THE DIVIDE...KBPI/KJAC/KPNA/KRKS ROUTES

VFR CONDITIONS WILL PREVAIL THROUGH TUESDAY NIGHT WITH SFC SOUTHWEST
WINDS INCREASING TO 15-20KTS OVER MUCH OF THE AREA FOR THE REST OF THIS
AFTERNOON. ISOLATED THUNDERSTORMS WILL DEVELOP DURING THE REST OF
THIS AFTERNOON AND WILL BE MOVING EAST THROUGH THE EARLY EVENING
HOURS. WINDS WILL DIMINISH WITH SUNSET. ISOLATED SHOWERS AND
POSSIBLY A THUNDERSTORM OR TWO WILL MOVE IN FROM THE SOUTHWEST
ACROSS THE AREA 06Z-12Z WEDNESDAY.

&&

.HYROLOGY...
A RIDGE OF HIGH PRESSURE WILL CONTINUE TO WARM TEMPERATURES ACROSS
MUCH OF THE FORECAST AREA FOR THE NEXT COUPLE DAYS. TEMPERATURES
WILL WARM TO THE LOW 90S FOR SOME PORTIONS OF THE STATE BY
WEDNESDAY. THESE WARMER TEMPERATURES MAY RESULT IN EXCESSIVE
SNOWMELT RELATED RUNOFF. THIS WILL POTENTIALLY INCREASE RIVER LEVELS
ACROSS THE AREA...WITH SOME FLOODING EXPECTED. FLOOD WATCHES AND
WARNINGS ARE CURRENTLY IN EFFECT FOR PORTIONS OF CENTRAL...NORTHWESTERN
AND NORTHEASTERN WYOMING THROUGH FRIDAY MORNING. THIS SITUATION
WILL CONTINUE TO BE MONITORED FOR ADDITIONAL STATEMENTS.
