AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
1150 AM MDT SAT JUN 21 2014

.UPDATE...
ISSUED AT 1100 AM MDT SAT JUN 21 2014

NOT A WHOLE LOT OF CHANGES MADE TO THE AFTN GRIDS. WEAK SHORTWAVE
IS SEEN ON WATER VAPOR IMAGERY OVER NORTHWEST COLORADO WITH
WIDESPREAD MID TO HIGH LEVEL CLOUDS CURRENTLY OVER SOUTHEAST WY. A
LITTLE WORRIED THAT THIS CLOUD COVER WILL LIMIT SFC HEATING AND
INSTABILITY THIS AFTN...ALTHOUGH WHERE STRONG TO SVR TSTM
POTENTIAL IS HIGHEST (NEBRASKA PANHANDLE) THERE HAS BEEN GOOD
WARMING THROUGH THE MORNING. THE HRRR MODEL HAS BEEN CONSISTENT AT
SHOWING A LARGE AREA OF SHOWERS AND EMBEDDED TSTMS OVER THE
PANHANDLE BETWEEN 22-01Z...WITH A MULTICELL APPEARANCE. WILL
CONTINUE THE MENTION OF SLIGHT RISK OF SVR STORMS IN THE
HWO...ALTHOUGH BULK SHEAR LOOKS A BIT MARGINAL AT 30-35 KTS FOR
MORE DISCRETE SUPERCELLS.

&&

.SHORT TERM...(TODAY THROUGH MONDAY)
ISSUED AT 312 AM MDT SAT JUN 21 2014

GLOBAL MODELS AND CURRENT WATER VAPOR IMAGERY SHOW A SHORTWAVE
APPROACHING FROM THE SOUTHWEST THAT IS PROGGED TO MOVE ACROSS OUR
AREA DURING THE AFTERNOON/EVENING HOURS TODAY. AT THE SURFACE...WE
NOTE A WELL DEFINED DRYLINE THAT EXTENDS FROM JUST NORTHWEST OF
CHADRON TO JUST EAST OF CHEYENNE. EAST OF THE DRYLINE MUCAPES ARE
RUNNING 400-800 J/KG ALREADY AND EXPECT BY THIS AFTERNOON WE WILL
SEE ENOUGH DEEP LAYERED INSTABILITY TO LIGHT OFF A FEW STRONG TO
SEVERE STORMS OVER THE NEBRASKA PANHANDLE WITH CAPES APPROACHING
2500 J/KG AND 1-6KM BULK SHEAR 25 TO 30 KTS ACROSS THE NORTHERN
NEBRASKA PANHANDLE...SUGGESTING THAT A FEW STORMS COULD START
TAKING ON SUPERCELL CHARACTERISTICS AS THEY MOVE EAST OUT OF
EASTERN WYOMING INTO NORTHWESTERN NEBRASKA. MODEL AND OBSERVED
SOUNDING DATA SHOW JUST ENOUGH OF A MIDLEVEL CAP TO HOLD BACK
CONVECTION UNTIL THE MID AFTERNOON HOURS...THEN BY 3 PM WE EXPECT
TO SEE SCATTERED STORMS INITIATING EAST OF A LUSK TO CHEYENNE
LINE...STRENGTHENING AS THEY MOVE EASTWARD INTO THE DEEPER
MOISTURE AND ZONE OF HIGHER INSTABILITY THROUGH LATE AFTERNOON
INTO THE EVENING HOURS. MAIN CONCERN FOR SEVERE STORMS IMPACTS
TODAY IS LARGE HAIL AND DAMAGING DOWNBURST WINDS IN EXCESS OF 60
MPH...MAINLY EAST OF A LINE FROM LUSK TO SIDNEY...ALTHOUGH
GREATEST POTENTIAL FOR VERY LARGE HAIL... HIGHER DOWNDRAFT WINDS
AND TO A LESSER DEGREE TORNADOES WILL BE FARTHER TO THE
EAST/NORTHEAST INTO SOUTH DAKOTA AND NORTHERN NEBRASKA WHERE SHEAR
VALUES FOR ORGANIZED UPDRAFTS WILL BE HIGHER.

LOOKING FARTHER TO THE WEST TODAY...LATEST HIGH RESOLUTION RAPID
REFRESH MODEL DOES HINT AT SOME WEAKER SHOWERS/STORMS FORMING UP
IN THE EARLY AFTERNOON IN THE HIGHER TERRAIN OVER OUR WESTERN
ZONES. WE CONTINUE TO MAINTAIN SLIGHT CHANCE/CHANCE POPS FOR
AFTERNOON SHOWERS AND STORMS IN THE WEST WITH THE EXCEPTION OF
THE WESTERN-MOST AREAS OF CARBON COUNTY. ANOTHER BREEZY DAY
EXPECTED ABOVE 8000 FT MSL WITH GUSTS TO 35 MPH POSSIBLE DURING
THE PEAK MECHANICAL MIXING PERIOD OF MID MORNING THROUGH LATE
AFTERNOON.

WE EXPECT ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS ON SUNDAY AS
A COLD FRONT SINKS SOUTHWARDS AND IS PROGGED IN THE MODELS TO BANK
UP ALONG AND EAST OF THE LARAMIE RANGE BY LATE AFTERNOON. MOST OF
THE STORMS SUNDAY SHOULD BE NOTED EAST OF A LINE FROM DOUGLAS TO
CHEYENNE IN THE REGION OF DEEPER MOISTURE AND INSTABILITY...WITH
LESS COVERAGE TO THE WEST. DEEP LAYERED INSTABILITY FOR STRONG
UPDRAFTS LOOKS A LITTLE MORE LIMITED ON SUNDAY...HOWEVER BULK
SHEAR VALUES ACROSS EASTERN WYOMING AND WESTERN NEBRASKA COULD GET
UP TO NEAR 30 KTS...SO A SMALL POTENTIAL FOR A FEW STRONGER
STORMS IS THERE. THE KEY THING WE WILL NEED TO WATCH FOR ON SUNDAY
WILL BE THE POTENTIAL FOR STORMS TO RE-DEVELOP OR TRAIN GRADUALLY
FROM NORTHWEST TO SOUTHEAST...MEANING SOME AREAS COULD SEE
MULTIPLE ROUNDS OF RAINFALL. QUESTION IS JUST HOW FAR SOUTH WILL
THE FRONTAL BOUNDARY GET AND IF WE WILL SEE ENHANCED BACK-BUILDING
OF STORMS WITH EAST/SOUTHEAST SURFACE FLOW WITH 25-35 KT MIDLEVEL
FLOW ABOVE IT. RIGHT NOW FORECAST CONFIDENCE AS TO IF OR WHERE ANY
FLASH FLOODING WOULD OCCUR ON SUNDAY IS NOT NEAR HIGH ENOUGH TO
WARRANT THE ISSUANCE OF A WATCH.

FOR MONDAY...MORE SCATTERED AFTERNOON SHOWERS AND THUNDERSTORMS
ARE EXPECTED FOR THE CENTRAL AND EASTERN ZONES IN THE REGION OF
DEEPER MOISURE.

.LONG TERM...(MONDAY NIGHT THROUGH FRIDAY)
ISSUED AT 312 AM MDT SAT JUN 21 2014

MODELS IN GENERALLY GOOD AGREEMENT WITH THE OVERALL PATTERN
THROUGH MOST OF NEXT WEEK...ALTHOUGH SOME DIFFERENCES ARE NOTED
BY DAY 7 REGARDING THE TIMING OF AN UNUSUALLY STRONG UPPER LEVEL
TROUGH ACROSS THE PACIFIC NORTHWEST FOR THIS TIME OF THE YEAR. THE
WEATHER PATTERNS APPEARS TO BE PRETTY ACTIVE NEXT WEEK AS A SERIES
OF SHORTWAVE DISTURBANCES EMBEDDED WITHIN THE QUASI-ZONAL FLOW
PUSH ACROSS THE FORECAST AREA EACH DAY THROUGH THURSDAY.

A LOW LEVEL SURFACE BOUNDARY WILL BE THE PRIMARY FACTOR IN
DETERMINING CONVECTION INITIATION EACH DAY DUE TO AMPLE LLVL
CONVERGENCE AND ADDITIONAL INSTABILITY. THE BOUNDARY POSITION WILL
FLUCTUATE BETWEEN THE CONTINENTAL DIVIDE AND ALONG THE I25
CORRIDOR THROUGH THE PERIOD...RESULTING IN SOME DIFFICULTY IN
PINPOINTING WHERE THE HIGHEST POTENTIAL OF CONVECTION WILL BE
ALONG WITH HEAVY RAINFALL. MODELS INDICATE THIS BOUNDARY WILL PUSH
FURTHER WEST AS THE DAYTIME PROGRESSES...AND THEN RETREAT EASTWARD
TOWARDS THE I25 CORRIDOR EARLY IN THE MORNING AND AROUND
SUNRISE...WITH SURFACE OBS LIKELY SHOWING A WESTERLY WINDS AS IT
RETREATS EASTWARD. THEREFORE...EACH DAY WILL BE SIMILAR WITH AT
LEAST A SCATTERED COVERAGE OF SHOWERS AND TSTORMS EACH DAY FROM
MONDAY EVENING THROUGH WEDNESDAY EVENING. 0-6 KM SHEAR WILL
RANGE FROM 35 TO 45 KNOTS EACH DAY...SUGGESTING SOME STRONG TO
MARGINALLY SEVERE TSTORMS EACH DAY THROUGH WEDNESDAY. ADJUSTED POP
ALONG AND EAST OF THE LARAMIE RANGE WITH VALUES BETWEEN 30 TO 45
PERCENT...HIGHEST IN THE AFTERNOON AND EVENING HOURS.
HOWEVER...WOULD NOT BE SURPRISED IF THESE STORMS OR SHOWERS
LINGERED WELL INTO THE OVERNIGHT HOURS DUE TO AVAILABLE MOISTURE
AND UPPER LEVEL DISTURBANCES MOVING OVER THE AREA.

ON THURSDAY...MODELS SHOW THE UPPER LEVEL FLOW BECOMING MORE
SOUTHWESTERLY AND INCREASING IN STRENGTH AHEAD OF A POTENT PACIFIC
STORM SYSTEM MOVING ONSHORE. THIS WILL RESULT IN THE LLVL
BOUNDARY...WHICH HAS ACTED SIMILAR TO A DRY LINE...FINALLY
RETREATING A BIT FURTHER EASTWARD...LIMITING CONVECTION TO THE
HIGH PLAINS WITH ONLY ISOLATED COVERAGE THURSDAY AFTERNOON. FRIDAY
APPEARS TO BE A TRANSITIONAL DAY...WITH THE HIGHLY AMPLIFIED 00Z
ECMWF SHOWING THE POTENT UPPER LEVEL TROUGH AND ASSOCIATED PACIFIC
STORM SYSTEM MOVING ACROSS THE GREAT BASIN REGION AND INTO THE
FORECAST AREA...BRINGING WIDESPREAD RAIN SHOWERS AND ISOLATED
THUNDER ALONG WITH MUCH COOLER TEMPERATURES. THE GFS IS NOT AS
AMPLIFIED AND IS CONSIDERABLY SLOWER WITH THE TROUGH...WITH A
PLEASANT DAY SETTING UP OVER THE FORECAST AREA ON FRIDAY.

BELOW NORMAL TEMPERATURES EARLY THIS WEEK WITH GRADUALLY WARM UP
BY THE MIDDLE OF THE WEEK AS HIGHS INCREASE INTO THE 80S TO NEAR
90 BY THURSDAY AFTERNOON. LOWERED TEMPERATURES A FEW DEGREES ON
FRIDAY WITH SOME UNCERTAINTY...BUT STILL NEAR NORMAL FOR THE TIME
OF THE YEAR.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY MORNING)
ISSUED AT 1148 AM MDT SAT JUN 21 2014

MAIN CONCERN FOR THIS FORECAST CYCLE IS THE THUNDERSTORM POTENTIAL
THIS AFTERNOON AND EVENING. THE KCYS RADAR IS ALREADY STARTING TO
LIGHT UP WITH SHOWERS AND THUNDERSTORMS DEVELOPING BETWEEN KCYS
AND KDGW. FOR NOW...HAVE KEPT VCTS IN THE TAFS GIVEN THE
UNCERTAINTY IN TIMING AND PRECISE LOCATION. WILL CONTINUE TO
MONTIOR THUNDERSTORM TRENDS THRU THE REST OF THE AFTERNOON MAINLY
FOR AIRFIELDS TO THE EAST OF THE LARAMIE RANGE. CONVECTION WILL
DISSIPATE BY AROUND SUNSET AS THE THUNDERSTORMS PUSH EAST TOWARDS
CENTRAL NEBRASKA. A COLD FRONTAL WILL PUSH SOUTH THROUGH THE AREA
TONIGHT...SO EXPECT WINDS TO TURN NORTHERLY ALONG WITH POTENTIALLY
A PERIOD OF MVFR CIGS AT KCDR/KAIA. NORTHERLY WINDS WILL TURN
GUSTY LATE SUNDAY MORNING WITH ANOTHER ROUND OF AFTERNOON
THUNDERSTORMS EXPECTED JUST BEYOND THIS TAF CYCLE FOR SUNDAY.

&&

.FIRE WEATHER...
ISSUED AT 312 AM MDT SAT JUN 21 2014

STILL SEE MINIMAL FIRE WEATHER IMPACTS THROUGH THE WEEKEND.
AFTERNOON HUMIDITY VALUES WILL DROP TO 10 TO 15 PERCENT FOR AREAS
ALONG AND WEST OF THE LARAMIE RANGE THIS AFTERNOON AND ON SUNDAY.
WEST TO SOUTHWEST WINDS WILL OCCASIONALLY GUST TO 30 MPH IN THE
HIGHER TERRAIN DURING THE PERIOD OF PEAK MECHANICAL MIXING BOTH
AFTERNOONS. HOWEVER...NO CRITICAL FIRE WEATHER THREAT IS
ANTICIPATED SINCE FUELS HAVE STILL NOT DRIED ENOUGH TO SUPPORT
SIGNIFICANT FIRE GROWTH. WE ARE STILL EXPECTING COOLER
TEMPERATURES SUNDAY INTO EARLY NEXT WEEK ALONG WITH A BETTER
CHANCE OF WETTING RAINS...ESPECIALLY TO THE EAST OF THE LARAMIE
RANGE.
