AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
337 PM MDT THU JUN 26 2014

.SHORT TERM...TONIGHT THROUGH FRIDAY

WE SHOULD SEE THREE DISTINCT ROUNDS OF CONVECTION DURING THE NEXT 24
HOURS. THE FIRST ONE IS NOW OCCURRING WITH A LEAD SHORTWAVE TROUGH
AHEAD OF THE MAIN APPROACHING TROUGH WHICH IS NOW TRACKING EAST
ACROSS THE GREAT BASIN. THIS LEAD WAVE HAS PRODUCED MAINLY LIGHT
SHOWERS ACROSS MUCH OF WESTERN WYOMING THIS MORNING. NOW THAT THIS
WAVE HAS MOVED EAST AND ALLOWED THE ASSOCIATED MID LEVEL CLOUDS TO
CLEAR OUT...A FRESH ROUND OF CONVECTION HAS DEVELOPED AND IS
PRODUCING RAPIDLY DEVELOPING THUNDERSTORMS ACROSS MAINLY NORTHERN WY
ALONG WITH LESS COVERAGE TO THE SOUTH. A SEVERE THUNDERSTORM WATCH
IS NOW IN EFFECT FOR WASHAKIE...BIG HORN AND JOHNSON COUNTIES. DEW
POINTS ARE AS HIGH AS 60 AT BYG. BEST CAPES AND LIFTED INDICES
HAVE BEEN IN THESE AREAS. THE THIRD ROUND OF SHOWER ACTIVITY WILL
BE MORE DIRECTLY ASSOCIATED WITH THE MAIN TROUGH ITSELF TONIGHT
AND FRIDAY. DYNAMICS ASSOCIATED WITH THE MAIN WAVE APPROACHING
FROM THE WEST HAS INITIATED STRONG STORMS IN THE FAR WEST AS WELL. ANOTHER
WAVE OF SHOWERS ALONG WITH A FEW EMBEDDED THUNDERSTORMS ASCT WITH
THIS SAME WAVE SHOULD MOVE INTO FAR WESTERN WY LATE THIS EVENING
AND SPREAD ACROSS SOUTHERN AND CENTRAL WY AFTER 12Z FRIDAY AND
THEN WILL PRIMARILY AFFECT AREAS ALONG AND NORTH OF THE OWL CREEK
MTNS AND ALONG AND EAST OF THE CASPER ARCH AFTER 18Z FRIDAY AS
DYNAMICS TRUMP OROGRAPHICS AND DAY TIME HEATING IN MANY AREAS. THERE
IS A HINT THAT A MID LEVEL CIRCULATION WILL TRY TO ESTABLISH
ITSELF TONIGHT AROUND 06Z OVER NORTH CENTRAL WY. WRAP AROUND
PRECIP WILL LIKELY CONTINUE FRIDAY AROUND THE BACK SIDE OF THIS
LOW OVER THE AFOREMENTIONED AREAS. THERE APPEARS TO BE A STRONG
POTENTIAL FOR FLOODING ALONG THE VICINITY OF THE TRACK OF THIS
CIRCULATION FROM ALONG THE OWL CREEK MTNS NORTH....MAINLY EAST OF
THE DIVIDE...ESPECIALLY IN AREAS THAT HAVE RECEIVED LOCALLY
COPIOUS AMOUNTS OF RAINFALL DURING THE PAST FEW DAYS FROM OTHER
CONVECTIVE CELLS...NAMELY THE OWL CREEK AND BIG HORN MTNS AS WELL
AS THE LOWER ELEVATIONS OF JOHNSON COUNTY. WENT AHEAD AND ISSUED A
FLOOD WATCH FOR THESE AREAS VALID 09Z TONIGHT THROUGH 00Z SAT. THE
WRF IS ADVERTISING AS MUCH AS 3.75 INCHES OF RAINFALL ACROSS
PORTIONS OF HOT SPRINGS COUNTY DURING THE NEXT 24 HOURS. IF ONE
CUTS THIS AMOUNT IN HALF...WHICH SEEMS TO WORK WELL WITH THE
WRF...SOME AREAS COULD RECEIVE BETWEEN 1.75 AND 2 INCHES OF
RAINFALL BY THE END OF FRIDAY. TEMPERATURES WILL COOL
SIGNIFICANTLY FRIDAY DUE TO THE COOL AIR ADVECTION ALONG WITH THE
NUMEROUS SHOWERS AND CLOUDS. MANY LOCATIONS COULD SEE HIGH
TEMPERATURES AT LEAST 10 TO 15 DEGREES COOLER FRIDAY THAN TODAY.
THE SNOW LEVEL WILL LIKELY DROP TO 10K ACROSS MUCH OF THE MTNS
FRIDAY. FRIDAY WILL FEEL MORE LIKE SPRING THAN SUMMER.

.LONG TERM...FRIDAY NIGHT THROUGH THURSDAY

TAIL END OF OUR ACTIVE SHORT TERM SYSTEM WILL LINGER INTO FRIDAY
EVENING WITH A GOOD CHANCE OF SHOWERS EAST OF THE DIVIDE...MOST
NUMEROUS IN THE MOUNTAINS WITH HIGHER PEAK SNOW SHOWERS. SYSTEM
MOVES OFF TO THE NE LATER FRIDAY NIGHT WITH GRADUALLY DECREASING
SHOWERS. ON SATURDAY...A DISTURBANCE MOVES ACROSS MT AND BRUSHES FAR
NRN WYOMING. BEST SHOT OF SHOWERS AND THUNDERSTORMS WILL BE IN THE
FAR NORTH...ESPECIALLY IN THE MOUNTAINS. DRIER WNW FLOW ON SUNDAY AS
HEIGHTS BEGIN TO RISE AND MID LEVEL TEMPERATURES WARM. SOME MARGINAL
INSTABILITY STILL POSSIBLE IN THE NRN MOUNTAINS SO WILL KEEP IDEA OF
ISOLATED SHOWERS AND A SLGT CHANCE OF TSTMS. IN ADDITION...ANOTHER
SHORTWAVE MOVING ACROSS MT MAY BE JUST CLOSE ENOUGH TO THE FAR NRN
ZONES TO AID AT LEAST A LITTLE. RIDGE CONTINUES TO BUILD TO THE WEST
EARLY NEXT WEEK WHILE STRONG UPPER LOW DEVELOPS OVER THE NRN HIGH
PLAINS AND SRN CANADA NORTH OF ND AND MN. COOLER AND GENERALLY MORE
STABLE AIR IS USHERED IN BEHIND ANOTHER COLD FRONT TO KEEP
TEMPERATURES WELL BELOW NORTH EAST OF THE DIVIDE MONDAY WITH SOME
MODERATION BY TUESDAY. IT'S NOT UNTIL WEDNESDAY AND THURSDAY OF NEXT
WEEK THAT THE GUIDANCE IS SHOWING THE RIDGE MOVING EITHER OVER US OR
JUST TO OUR WEST WITH VERY WARM MID LEVEL TEMPERATURES LEADING TO
POTENTIALLY A COUPLE HOT DAYS. BUT UNTIL THEN...A FEW MORE COOL DAYS.

&&

.AVIATION.../00Z ISSUANCE/

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

A STRONG UPPER LOW...ESPECIALLY FOR SUMMER...OVER THE PACIFIC
NORTHWEST TODAY...HAS PUSHED A COLD FRONT THROUGH THE AREA AROUND
MID DAY TODAY. SOME CONVECTION...EVEN SCATTERED TO LOCALLY
NUMEROUS SHOWERS/THUNDERSTORMS EXPECTED DURING THE REMAINDER OF
THIS AFTERNOON. ALTHOUGH CONVECTION WILL DECREASE IN INTENSITY IN
THE EVENING...DYNAMICS ASSOCIATED WITH THE UPPER LOW WILL KEEP
GOOD CHANCES OF CONVECTION...ISOLD THUNDER...ONGOING ACROSS
NORTHWEST WYOMING ALL NIGHT. MVFR/IFR CONDITIONS WILL BE POSSIBLE
TODAY..BUT MORE PERSISTENT MFVR CONDITIONS ARE
POSSIBLE...ESPECIALLY KJAC AFTER 00Z. MOUNTAINS WILL BE OBSCURED
AT TIMES TODAY...WITH NORTHWEST MOUNTAINS INCREASING BECOMING
OBSCURED DURING THE EARLY EVENING. THERE IS A LIKELIHOOD OF
WIDESPREAD NEAR MVFR CEILINGS DEVELOPING AFTER 12Z UNTIL 18Z ALONG
WITH LOCAL MVFR CONDITIONS/MTN OBSCURATIONS AND ISOLD IFR
CONDITIONS IN WAKE OF THE COLD FRONT.

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

A COLD FRONT ASSOCIATED WITH A STRONG UPPER LOW BEGINS TO PUSH
INTO THE AREA. THE MAIN BRUNT OF THE COLD FRONT IS EXPECTED
THROUGH 03Z. ISOLATED TO SCATTERED CONVECTION IS EXPECTED DURING
THE REMAINDER OF THIS AFTERNOON...WITH THE BEST SHOT ACROSS THE
NORTH AND NORTHEAST SECTIONS OF THE AREA. THERE COULD BE A BRIEF
BREAK IN THE CONVECTION IN THE EARLY EVENING...BEFORE MORE SHOWERY
ACTIVITY DEVELOPS WITH THE APPROACH OF THE MID/UPPER LOW BY LATE
EVENING...WITH THE BEST CHANCE OVER THE BIG HORN BASIN. BRIEF
MVFR/IFR CONDITIONS ARE EXPECTED IN CONVECTION. THERE IS A
LIKELIHOOD OF WIDESPREAD MVFR CEILINGS DEVELOPING FROM 12Z TO 18Z
AT KLND AND KRIW AND AFTER 18Z AT KWRL/KCOD/KCPR ALONG WITH LOCAL
MVFR CONDITIONS/MTN OBSCURATIONS AND ISOLD IFR CONDITIONS IN WAKE
OF THE COLD FRONT.

&&

.FIRE WEATHER...

THE COLD FRONT THAT IS NOW OVER WESTERN WYOMING WILL MOVE ACROSS ALL
AREAS LATER TONIGHT...BUT BEFORE IT DOES THERE WILL BE SOME
ISOLATED TO WIDELY SCATTERED SHOWERS AND THUNDERSTORMS AGAIN.
POTENTIALLY SEVERE THUNDERSTORMS WILL OCCUR ACROSS CASPER DISPATCH
WITH STRONG TO SEVERE STORMS ALSO POSSIBLE ACROSS CODY DISPATCH
THIS EVENING. WINDS WILL COME AROUND TO THE WEST/NORTHWEST FOR
MOST ZONES AS THE FRONT MEANDERS EASTWARD DURING THE REMAINDER OF
THIS AFTERNOON AND EVENING. STRONGER GUSTY WEST WINDS WILL LAY
ACROSS THE SOUTHERN ZONES 277 278 279 AND 289 WHERE IN COMBINATION
WITH SOME MIN RH VALUES IN THE 20S...WILL ENHANCE FIRE WEATHER
CONCERNS THROUGH EARLY THIS EVENING. MORE SHOWER AND THUNDERSTORM
ACTIVITY FOR FRIDAY...ALONG WITH MUCH COOLER TEMPERATURES AND MORE
CLOUD COVER ACROSS THE STATE AS WELL AS A GOOD CHANCE FOR WETTING
RAIN ACROSS THE STATE. THERE IS A POSSIBILITY OF FLOODING DUE TO
SUBSTANTIAL RAINFALL ACROSS ZONES 281...285 AND 287. THINGS WILL
CLEAR UP A BIT ON SATURDAY WITH A STEADY DRY AND WARM WESTERLY
FLOW DEVELOPING...ESPECIALLY ACROSS RAWLINS DISPATCH.
