AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
418 PM MDT WED MAY 28 2014

.SHORT TERM...TONIGHT THROUGH SATURDAY

WITH A TEMP/DP SPREAD OF 60 DEGREES IN SOME AREAS...THE THUNDERSTORM
CELLS THAT HAVE OCCURRED UP TIL NOW...FROM A NORTHEAST BOUND
SHORTWAVE BEING SLUNG NORTHEAST FROM THE PAC NW LOW... HAVE BEEN
MAINLY WIND PRODUCERS WITH WIND THUNDERSTORM WIND GUSTS GENERALLY
IN THE 40 TO 55 MPH RANGE. MAINLY SPOTTY RAINFALL HAS OCCURRED
THUS FAR. THESE CELLS ARE MOVING NORTH INTO SLIGHTLY JUICIER AIR
WITH DEW POINTS IN THE 20S SOUTH...30S MOST EVERYWHERE ELSE WITH
UPPER 30S FAR WEST AND FAR NORTH. PREVAILING WINDS ARE GENERALLY
FROM THE SOUTHWEST AT 15 TO 30 MPH ALONG WITH SOUTHEAST WINDS AT
10 TO 20 MPH OVER JOHNSON COUNTY PROVIDING SOME SHEAR. A SEVERE
THUNDERSTORM WATCH HAS BEEN ISSUED FOR JOHNSON...BIG HORN AND
WASHAKIE COUNTIES TO ACCOUNT FOR STRAIGHT LINE THUNDERSTORM WIND
GUSTS AND WHATEVER COULD RESULT FROM WIND SHEER IN JOHNSON COUNTY.
MENTIONED THE POTENTIAL FOR LARGE HAIL FOR ONLY NORTHEAST JOHNSON
COUNTY.

THEN FOR THURSDAY...THE CLOSED LOW THAT IS NOW OVER THE PACIFIC
NORTHWEST WILL TRACK NORTHEAST TO SOUTHERN CANADA AND WILL SWING
ANOTHER SHORTWAVE NORTHEAST ACROSS THE AREA. AS THE RIDGE OF HIGH
PRESSURE THAT TOOK TEMPERATURES WELL UP INTO THE 80S THIS
AFTERNOON SHIFTS EAST...THIS SHORTWAVE WILL BE ABLE TO EJECT A
COLD FRONT SOUTH ACROSS THE AREA INCREASING THE CHANCES AND
COVERAGE OF WET THUNDERSTORM DEVELOPMENT THURSDAY AFTERNOON ACROSS
THE CWA. LIFTED INDICES WILL BE DOWN TO -5 IN NORTHEAST JOHNSON
COUNTY THURSDAY AFTERNOON.

BY FRIDAY...AN UNSTABLE LOW LEVEL UPSLOPE FLOW WILL BECOME
ESTABLISHED BEHIND THURSDAYS FRONT WHICH WILL RESULT IN MORE
NUMEROUS SHOWERS WITH LESS THUNDER. TEMPS WILL BE COOLER FRIDAY
EAST OF THE DIVIDE THEN ON THURSDAY FROM THE UPSLOPE FLOW.

ON SATURDAY THE LONG WAVE PACIFIC TROUGH WILL MOVE INLAND
RESULTING IN AN INCREASINGLY DIFLUENT SOUTHWEST FLOW RESULTING IN
IN LESS SHOWER AND THUNDERSTORM COVERAGE BUT MORE INTENSE
THUNDERSTORMS AND LOCALLY HEAVIER RAINFALL SATURDAY. IN
FACT...LIFTED INDICES ARE PROGGED BY THE GFS TO BE -7 IN NORTHEAST
JOHNSON COUNTY SATURDAY AFTERNOON.

.LONG TERM...SUNDAY THROUGH WEDNESDAY

OVERALL...MORNING COMPARISON OF LR MDLS NOT IMPRESSIVE AT
HANDLING NEXT UPR TROF/SFC FRONT WITH DIFFERENCES GREATLY
AFFECTING PLACEMENT OF BOUNDARY AND ASSOCIATED PRECIPITATION
POTENTIAL...WITH GFS LEANING TOWARDS TO NRN CWA...WHILE THE EURO
BROAD-BRUSHES THE ENTIRE AREA WITH A MORE SRN SOLUTION. INTERESTED
TO SEE MID-DAY COMPARISON OF 12Z RUN. OTHERWISE...THE LR MDLS DO
RETURN TO A SIMILAR UPR PATTERN BY TUE AND WED ODDLY
ENOUGH....WITH SOME MODEST TO FLAT RIDGING LOOKING TO BEGIN IN
THIS PERIOD...RAISING HIGH TEMPS BACK TO THE UPR 70S TO NEAR 80S.

AT THE BEGINNING OF THE PERIOD SAT NIGHT...WIDELY SCATTERED TO
SCATTERED CONVECTION WILL BE IN PROGRESS...WITH PERHAPS THE STRONGEST
STORMS (NEAR SVR) OF THE DAY BREAKING CAP NEAR AND NORTH OF NRN
NATRONA INTO JOHNSON COUNTY...WITH A LESSER POSSIBILITY TO THE WEST
AND INTO  HOT SPRINGS BIG HORN COUNTIES. FROM LATE AFTERNOON SAT
THRU THE OVERNIGHT PERIOD...HYDRO POTENTIAL OVR AND AROUND THE BIG
HORNS WILL RANGE FROM .25 TO .75 IN...WITH .10 TO .30 INCHES ACROSS
THE LOWER ELEVATIONS EAST OF THE DIVIDE...AND SLIGHTLY LESS
EVERYWHERE ELSE IN THE CWA.

SUN...DIFFERENCES IN HANDING THE APPROACH OF THE NEXT UPR TROF AND
ASSOCIATED POSITION OF THE SFC LOW AND FRONT. ATTM...THE GFS HAS UPR
LVL FORCING MOVING THRU IN THE MORNING WITH ONGOING SHOWERS
ETC...AND A WEAK FRONT THRU AND LEE LOW DEVELOPING IN ERN WY AND THE
DAKOTAS. THIS WOULD KEEP THE AFTERNOON BOUNDARY/FRONT MAINLY UP AND
OVR THE NRN TIER OF ZONES. THE EURO DEVELOPS THE LEE LOW FURTHER S
INTO ERN CO WHICH ALLOWS FOR AN ERLY FEED OF LOW END MOISTURE BACK
INTO THE FA...ESPECIALLY E OF THE DIVIDE. BOTH MDLS HOWEVER HAVE
SIMILAR THINKING THE HOW THE UPR LVLS WILL EVOLVE...AND ARE BECOMING
BETTER SUITED FOR EXTENDING CONVECTION THROUGH THE NIGHT-TIME PERIOD
WITH LOWER MID/UPR TEMPS ACROSS A SLIGHTLY BROADER AREA. THIS WILL
BULLSEYE BETTER PRECIP CHANCES ACROSS THE CENTRAL AND NORTHERN FA.
WILL SEE HOW/IF THIS CHANGES WITH THE LATEST MDLS RUN. CURRENT
THINKING HAS ABOUT A 60/40 GFS/ECMWF BLEND OF THE TWO MDLS. EITHER
WAY...BY SUNDAY NIGHT THE EMPHASIS FOR SIGNIFICANT PRECIP LAYS
ACROSS THE NRN HALF OF THE CWA...AND THIS MAY FURTHER AGGRAVATE THE
ONGOING HYDRO SITUATION ESPECIALLY OVER THE ABSAROKAS AND BIG HORN
MOUNTAINS. WHILE UPR LVL JET INFLUENCE DOES NOT CURRENTLY LOOK TOO
SIGNIFICANT AND MANY STORMS WILL LIKELY BE EMBEDDED IN
SHOWERS...THERE WILL BE AN AREA NEAR THE FRONT/BOUNDARY WHICH MAY
OFFER BETTER SHEAR POTENTIAL TO HAVE A FEW STRONGER STORMS. TOUGH TO
BET ON STRONG/SVR IN ANY OTHER AREAS.

MON AND BEYOND...TRANSITION TO INCREASINGLY ZONAL FLOW W/ PERIODIC
OCCURRENCES OF FLEETING DISTURBANCES ALOFT WILL KEEP CONVECTIVE
ACTIVITY GOING EACH DAY THROUGH THE FCST PERIOD. HOWEVER... THE
CURRENT SOLUTIONS PRESENTED THROUGH THE END OF THE FORECAST PERIOD
WOULD TEND TO FAVOR BETTER CHANCES FOR CONVECTIVE PRECIP ACROSS THE
NRN HALF OF THE FA...ESPECIALLY IN THE MOUNTAINS. HIGH TEMPS
CONTINUE TO LOOK TO HOLD AOB 80 THROUGH THE FCST...WITH WED BEING
THE WARMEST. HOW THE WEAK UPR RIDGE PROGRESSES BY THE END OF THE
FCST WILL DETERMINE IF WARMER TEMPS SHOULD BE WARRANTED AT THAT
TIME. WILL WAIT AND WATCH FOR NOW.

.AVIATION.../00Z ISSUANCE/
EAST OF THE DIVIDE...KCOD/KCPR/KLND/KRIW/KWRL ROUTES

INCREASING MID-LEVEL MOISTURE WILL BLOSSOM INTO WIDELY SCATTERED
SHOWERS AND THUNDERSTORMS THIS AFTERNOON WITH THE MAIN HAZARD OF
MICROBURST WIND GUSTS OF 50KT OR HIGHER. HOWEVER THERE IS A THREAT
OF LARGE HAIL IN NORTHEAST JOHNSON COUNTY AND THUNDERSTORM WIND
GUSTS OF 60 MPH OR MORE FOR PORTIONS OF JOHNSON...BIG HORN AND
WASHAKIE COUNTIES THROUGH 04Z THIS EVENING WHERE LOCAL LIFR
CONDITIONS ARE LIKELY. OTHERWISE SFC SOUTH WIND AT 15-25KT BY
AFTERNOON WILL GIVE WAY TO INCREASINGLY ERRATIC SHOWER AND
THUNDERSTORM OUTFLOWS THROUGH THE REST OF THE AFTERNOON. SHOWER
AND THUNDERSTORM ACTIVITY ALONG WITH THE GUSTY WIND WILL SUBSIDE
AFTER SUNSET AT MOST LOCATIONS WITH ISOLATED SHOWERS LINGERING
AFTER 06Z THURSDAY. MORE NUMEROUS THUNDERSTORMS ARE EXPECTED
THURSDAY AFTERNOON WITH MVFR AND LCL IFR CONDITIONS EXPECTED WITH
THIS ACTIVITY ALONG WITH SOME MTN OBSCURATIONS.

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

MID-LEVEL MOISTURE WILL BLOSSOM INTO WIDELY SCATTERED SHOWERS AND
THUNDERSTORMS MAINLY EAST OF A KEMM-KJAC LINE. THE MAIN THREAT WILL
BE MICROBURST WIND GUSTS NEAR 50KTS OR HIGHER. SFC SOUTHWEST WIND AT
15-25KT WILL PREVAIL...WITH THESE WINDS BECOMING INCREASINGLY
ERRATIC AS SHOWER AND THUNDERSTORM OUTFLOW BOUNDARIES BECOME
DOMINANT. THUNDERSTORMS AND WINDS WILL DIMINISH AROUND SUNSET. A
COLD FRONT WILL BRING SCATTERED SHOWERS AND POSSIBLY A FEW
THUNDERSTORMS INTO THE NW...MAINLY VCNTY AND NORTH OF A KJAC- KDUB
LINE 06Z-12Z THURSDAY. ISOLATED TO WIDELY SCATTERED THUNDERSTORMS
ARE EXPECTED AFTER 18Z THU...MAINLY IN THE MTNS.

&&

.HYGRO...

A RIDGE OF HIGH PRESSURE WILL CONTINUE THE WARM TEMPERATURES
ACROSS MUCH OF THE FORECAST AREA FOR THE NEXT COUPLE DAYS.
THESE WARMER TEMPERATURES MAY RESULT IN EXCESSIVE SNOW MELT
RELATED RUNOFF. HOWEVER...TEMPERATURES WILL NOT REACH THE LEVELS
THAT OCCURRED THIS AFTERNOON FOR THE REST OF THE WEEK. 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. MORE NUMEROUS SHOWERS AND
THUNDERSTORMS ARE EXPECTED FRIDAY THROUGH THE WEEKEND.
