Severe Thunderstorm Warning 66, NWS Riverton, WY

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
211 PM MDT THU AUG 22 2013

.SHORT TERM...TONIGHT AND FRIDAY
MORNING SHORTWAVE THAT CAUSED A FEW SHOWERS AND THUNDERSTORMS
OVER OUR NERN ZONES IS MOVING AWAY FROM THE AREA AS EXPECTED. THE
NEXT APPROACHING DISTURBANCE IS LIFTING NE TOWARDS SWEETWATER
COUNTY. LIMITED INSTABILITY DOWN THERE BUT WITH APPROACHING
DISTURBANCE SHOULD BE ENOUGH TO PRODUCE SHOWERS AND THUNDERSTORMS
THROUGH THE EVENING. IN THE FAR WEST...OLD CONVECTIVE DEBRIS FROM
YESTERDAY'S CONVECTION OVER ARIZONA IS PROVIDING SOME ADDITIONAL
MOISTURE AND DISCONTINUITY BOUNDARY FOR DIFFERENTIAL HEATING FOR
AIDED THUNDERSTORM DEVELOPMENT AREA. NERN ZONES HAVE WEAK FRONTAL
BOUNDARY TO FOCUS ON ALONG WITH BETTER LOW LEVEL MOISTURE.
CONVECTION WILL GRADUALLY WEAKEN LATER THIS EVENING WITH A FEW
SHOWERS OR POSSIBLY A THUNDERSTORM LINGERING OVERNIGHT. ON
FRIDAY...A COUPLE DISTURBANCES COULD COME INTO PLAY. ONE IS COMING
OUT OF APPROACHING NRN CA UPPER LOW AND IS ASSOCIATED WITH A JET
STREAK. THE VORT AND RIGHT ENTRANCE REGION OF THE JET STREAK
APPROACHES THE NW LATER TOMORROW AND INTO FRIDAY EVENING WHICH
COULD PROVIDE AIDED SUPPORT FOR CONVECTION OVER THE NWRN AREAS
LATER FRIDAY. INCREASED THIS AREA TO SCATTERED POPS. DRIER AIR
MOVES INTO THE SW BUT ANOTHER APPROACHING DISTURBANCE LATE IN THE
DAY WARRANTS AT LEAST ISOLATED COVERAGE WITH SMALL AMOUNTS OF
FORECAST CAPE. GENERAL SW FLOW ACROSS THE AREA WITH SOME BREEZY
CONDITIONS IN THE MOUNTAINS AND WIND CORRIDOR AT TIMES.

.LONG TERM...FRIDAY NIGHT THROUGH THURSDAY
WV IMAGERY AND RADAR SHOWING EXITING SW ACROSS NERN CORNER OF CWA
THIS MORNING...WITH ANOTHER WEAKER IMPULSE IN THE ECNTRL TO NERN
PORTION OF UT...WHICH SHOULD SKIRT OUR SRN FA LATER TODAY...AND
PERHAPS OUR SERN TO E CWA TOMORROW MIDDAY. IMAGERY IS ALSO SHOWING
ANOTHER DISTURBANCE IN CNTRL ID WHICH WILL SWEEP BY OUR NRN BORDER
REGION THIS AFTERNOON. FURTHER UPSTREAM...BUT DOWN SOUTH...IMAGERY
ALSO SHOWING YET ANOTHER SW DISTURBANCE IN THE NRN TIP OF BAJA/SWRN
AZ/SERN CA...WHICH WILL RIDE THE RIDGE AND SHOULD OVERRUN AT LEAST
OUR WRN FA ON FRIDAY AND BE IN EFFECT BY THE START OF MY FCST
PERIOD. THE CUT LOW IN THE EPAC...JUST W OF SAN FRAN...STILL LOOK ON
TRACK TO LIFT OUT AND EJECT TO THE NE...STAYING NW OF OUR
REGION...AND TIMING DOES NOT LOOK QUITE AS SYNCHRONIZED WITH THE SRN
IMPULSE AS IT DID A DAY AGO...NOT THAT IT REALLY MATTERS.

FRI NIGHT...WHILE TODAY WILL BE MORE OF AN ERN CWA...PARTICULARLY
JOHNSON AND SOME NATRONA COUNTY...AND MORE SPECIFICALLY A BIG HORN
MOUNTAIN SHOW...WITH LESS CHANCES AND AMOUNTS ACROSS THE WRN
HIGHLANDS...FRIDAY'S ACTION WILL BE SPLIT FROM EARLIER ACTIVITY IN THE
ERN FA...TO EVENING SHOWERS AND THUNDER RIDING UP THE WRN CORRIDOR
ALONG WITH THE ABOVE MENTIONED DISTURBANCE NOW IN/NEAR NRN BAJA. AS
FAR AS STORM STRENGTH GOES...THERMODYNAMICS AND EFFECTIVE SHEAR NOT
PARTICULARLY IMPRESSIVE ANYWHERE. HOWEVER...THAT SAID THERE WILL
STILL BE THREE AREAS TO WATCH FOR PESKY ISOLATED STRONGER STORMS
FRIDAY EVENING. 1 THE NORTHWEST CORNER OF THE CWA...IN AND AROUND
THE YELLOWSTONE REGION...AS SLIGHTLY DEEPER MOISTURE...INSTABILITY
AND DIFLUENT UPR SHEAR AND PROXIMITY TO LIFTING JET...ASSOCIATED
WITH BOTH LIFTING EPAC TROF AND THE SW DISTURBANCE...WILL GIVE A
FLEETING GLIMPSE AT SCATTERED 20 TO 30 MPH STORMS WITH WINDS TO 35
MPH AND SMALL HAIL LESS THAN 1/2 INCH. 2 IN AND NEAR SWEETWATER
COUNTY WHICH WILL HAVE A MUCH DRIER BL BUT STILL DECENT ML MOISTURE
TO WORK WITH ...PRODUCING SLOWER MOVING AND MORE ELEVATED CONVECTION
THAN THEIR COUNTERPARTS UP NORTH...BUT WITH WIND GUST POTENTIAL TO
45 MPH. 3 WILL INCLUDE THE BIG HORN HORN MOUNTAINS AND THEN THE
EXTREME ERN PORTIONS OF JOHNSON AND NATRONA COUNTIES WHICH WILL HAVE
MORE ISOLATED STORMS BUT WITH THE POTENTIAL TO PRODUCE BOTH SMALL
HAIL TO A HALF AN INCH AND WINDS GUSTS TO 45 MPH. ALL OF THE
ACTIVITY SHOULD BE DONE ACROSS THE CWA EXCEPT FOR THE NWRN CWA WHERE
SHOWERS/THUNDER COULD LINGER TIL MIDNIGHT. SO RIDERS OF THE GREATER
YELLOWSTONE BICYCLE RIDE TAKE CARE WHILE WHILE FINISHING UP AND/OR
CAMPING NORTH OF THE BORDER.

SATURDAY...MOISTURE ON THE DECLINE OUT WEST...BUT STILL INSTABILITY
AND UPR FORCING FROM THE END OF FRIDAY EVENING'S SW. SO...CONVECTION
WILL BEGIN EARLIER ACROSS THE WRN CWA...BUT ALSO END A BIT EARLIER
THAN ON FRIDAY. AGAIN...RIDERS OF THE YELLOWSTONE RIDE WILL BE AFFECTED BY
THUNDERSTORMS PARTICULARLY AFTER THEIR MID DAY LUNCH BREAK AND
THROUGH THE REST OF THEIR RIDE TO BEARTOOTH PASS AND BACK. STORMS
COULD PRODUCE BOTH HEAVY RAIN AND SMALL HAIL OR GRAUPEL IN ADDITION
TO FREQUENT LIGHTNING AS THEY TRY TO LEAVE THE HIGHER TERRAIN BUT
CONTINUALLY REFORM. HIGH TEMPS OVR MUCH OF THE RIDE WILL STRUGGLE TO
MAKE IT INTO THE MID 50S...AND MAY NOT MAKE IT TO 40 NEAR THE TOP OF
THE PASSES. THIS TOGETHER WITH POSSIBLE WET CONDITIONS WILL MAKE IT
FEEL QUITE COOL AT TIMES...BRRR.

EAST OF THE DIVIDE...A SLIGHTLY LATER AND MORE ISOLATED SHOW IS
EXPECTED...EXCEPT FOR THE BIG HORN MOUNTAINS WHICH WILL BE UNDER
MORE OF THE SAME INFLUENCE THAT THE WRN CWA WILL EXPERIENCE. EXPECT
THE BASINS TO BE RELATIVELY PRECIP FREE FOR THE MOST PART WITH THE
SRN AND ERN PORTIONS OF THE CWA PUTTING UP CONVECTION MID AFTERNOON
ASSOCIATED WITH ANOTHER RING O FIRE UPR DISTURBANCE. WITH LL SWRLY
FLOW ACROSS NEARLY THE ENTIRE CWA...SAVE THE MOUNTAINS...DO NOT
EXPECT AVAILABLE MOISTURE TO BE SIGNIFICANT...NOR CAPE. AND NOTHING
ELSE LEADS TO PREDICT MUCH OF ANYTHING WITH THESE STORMS...OTHER
THAN SOME ANNOYING WIND GUSTS AT TIMES...ESPECIALLY IF CONVECTION
CAN ACTUALLY GET OFF THE MOUNTAINS AND WORK ITS WAY OVER THE LOW
LANDS.

SUNDAY AND BEYOND...LRMS ALL BASICALLY SINGING THE SAME SONG...WITH
SLIGHTLY DIFFERENT TUNES THROUGHOUT THE REST OF THE FCST PERIOD.
AGAIN IT COMES DOWN TO A MATTER  THE UPPER LEVEL POSITION OF THE
MIDDLE CONUS HIGH...AND THE RELATIVE POSITION OF SFC SET UP AND HOW
CLOSE WE WILL BE TO LEE TROFING...CO HIGH...AND SW CONUS/GREAT BASIN
LOW... WILL ALL COME INTO PLAY AND LAY OUT HOW MUCH MOISTURE WILL BE
AVAILABLE FOR PRECIP. MDLS ARE NOW STARTING TO HANDLE THE
DEVELOPMENT...MOVEMENT...AND DISSIPATION OF THE PAC TROPICAL CYCLONE
OFF OF MEX MORE SIMILARLY...BASICALLY KILLING IT LATE ON
SUNDAY/EARLY ON MONDAY...THEN SHEARING THE MOISTURE APART...BUT
INJECTING SOME INTO THE S TO SW FLOW OVER OF THE SW CONUS WHICH
WOULD A LEAST IN PART HEAD OUR DIRECTION. GFS IS MORE BULLISH WITH
MOISTURE THAN THE EURO...BUT BOTH ALSO WRING MUCH OF THE MOISTURE
OUT ACROSS THE SOUTHWEST HIGHLANDS BEFORE IT GETS HERE...AS USUAL.
MOST LIKELY...IF SOME OF THAT MOISTURE DOES MAKE IT HERE...IT WILL
BE USED DURING THE MONDAY PERIOD OF THE FORECAST AND PROBABLY OVER
THE WRN FA. STILL HARD TO GET EXCITED ATTM.

.AVIATION.../00Z ISSUANCE/
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE
EARLY EVENING BEFORE DIMINISHING TO ISOLATED COVERAGE FOR THE LATER
OVERNIGHT HOURS. MOUNTAINS WILL OBSCURED AT TIMES DURING ANY PASSING
SHOWERS OR THUNDERSTORMS ALONG WITH BRIEF MVFR CONDITIONS. THE MORE
CONCENTRATED SHOWERS WILL BE OVER THE MOUNTAINS...ESPECIALLY IN AND
NEAR THE ABSAROKAS. THUNDERSTORMS WILL BE MORE
ISOLATED IN COVERAGE ON FRIDAY EXCEPT IN THE FAR WEST WHERE SCATTERED
MOUNTAIN THUNDERSTORMS ARE EXPECTED TO DEVELOP ONCE AGAIN.

.FIRE WEATHER...
WIDELY SCATTERED TO SCATTERED THUNDERSTORMS WILL PREVAIL THROUGH
THIS EVENING BEFORE DECREASING TO ISOLATED THE REMAINDER OF TONIGHT
AND FRIDAY MORNING. ISOLATED THUNDERSTORMS WILL COVER THE ENTIRE AREA
FRIDAY AFTERNOON EXCEPT IN THE NORTHWEST WHERE SCATTERED
THUNDERSTORMS ARE EXPECTED.

.RIW WATCHES/WARNINGS/ADVISORIES...NONE.
