AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
114 PM EDT SUN JUN 5 2011

...UPDATED FORECAST AND AVIATION DISCUSSION...

...FORECAST UPDATE...

AS SUSPECTED...THE STORMS THAT WERE NEAR EVANSVILLE PROPAGATED
MORE SOUTH-SOUTHEAST WHERE THE HIGHER SURFACE DEWPOINTS AND MORE
NEGATIVE LI/S RESIDE. THIS IS ALSO WHERE LAST NIGHT/S OUTFLOW
BOUNDARY FROM CONVECTION ACROSS INDIANA STOPPED. GIVEN THE
ATMOSPHERIC CONDITIONS ACROSS THIS REGION...SPC HAS ISSUED A SEVER
THUNDERSTORM WATCH. ALSO...THE SECOND LINE OF STORMS IN ILLINOIS
AND INDIANA HAVE DISSIPATED TO MAINLY RAIN SHOWERS WITH A FEW
ISOLATED THUNDERSTORMS. HAVE ADJUSTED LIKELY POPS TO ENCOMPASS OUR
SOUTHWESTERN AND SOUTHERN CWA...WITH CHANCE POPS /50 PERCENT/
ELSEWHERE FOR THE REST OF THE AFTERNOON. ALSO...ADJUSTED TEMPS
DOWN ONCE AGAIN...WITH THE SOUTHERN CWA REMAINING THE WARMEST /LOW
90S/. UPDATED PRODUCTS FOR FORECAST CHANGES AS WELL AS THE SEVERE
THUNDERSTORM WATCH HAVE BEEN ISSUED.

.SHORT TERM (TODAY AND TONIGHT)...

IT APPEARS WE WILL START THE DAY OFF MOSTLY CLEAR AND RELATIVELY
STABLE WITH OUTFLOW BOUNDARIES FROM SATURDAY NIGHTS STORMS TO OUR
NORTH MOVING SWD THRU MOST/ALL OUR FORECAST AREA AND SENDING
DEWPOINTS DOWN INTO THE LOWER/MID 60S. OUR FAR SWRN AREAS MAY STAY
WITH DEWPOINTS AROUND 70 BY SUNRISE. SOME RECOVERY WILL TAKE PLACE
AS WE HEAT UP SUNDAY WITH CDFNT EXPECTED TO BE POSITIONED FROM
CENTRAL/SOUTHERN INDIANA ESE INTO NERN KY NEAR THE OHIO RIVER.

FRONT SHOULD SHIFT SEWD INTO CENTRAL KY DURG THE AFTERNOON WITH
MID/UPPER NW FLOW AND LIKELY STALL IN SWRN KY LATE TNGT. WITH THIS
FORECAST...HAVE THE MOST FAITH IN THE NAM/HRRR/LOCAL WRF WHICH ALL
SHOW THE CURRENT CONVECTIVE DEVELOPMENT IN NORTHERN MISSOURI AND
MOVEMENT INTO OUR N/NWRN FA BY MIDDAY IN A WEAKENING PHASE...BEFORE
STRENGTHENING IT SOMEWHAT DURING THE AFTERNOON. DOUBT INSTABILITY
WILL RECOVER TO THE LEVELS OF YESTERDAY...HOWEVER WITH OLD OUTFLOW
BOUNDARIES AROUND AS WELL AS THE FRONTAL BNDRY...WILL LEAVE A
MENTION OF ISOLATED TO SCATTERED TSTMS IN THE FORECAST...WITH THE
GREATEST COVERAGE/INTENSITY IN THE AFTERNOON/EARLY EVENING...
ASSOCIATED WITH PEAK HEATING. THE BEST TIME AND PLACE FOR BLOSSOMING
STORMS APPEARS TO BE ACROSS OUR ERN COUNTIES IN THE LATE
AFTERNOON/EARLY EVENING...WHERE POPS WILL BE THE HIGHEST.

EXPECT TEMPS AND DEWPOINTS LOWER THAN YESTERDAY WITH THE POSSIBLE
EXCEPTION OF OUR FAR SWRN FORECAST AREA...BUT EVEN THERE...HEAT
INDICES SHOULD LEVEL OFF IN THE MID/UPPER 90S.

TSTM CHCS SHUD BE ON THE WANE AFTER 00Z MON AS AN INFLUX OF DRIER
AIR MOVES NE TO SW ACROSS OUR REGION. TEMPS SHUD SETTLE INTO THE
MID/UPPER 60S MOST PLACES.

.LONG TERM (MONDAY - SUNDAY)...

MONDAY - WEDNESDAY...

UPPER LEVEL RIDGE AXIS WILL BEGIN TO SLIDE EAST ON MONDAY...
CENTERING ITSELF OVER THE TENNESSEE VALLEY BY TUESDAY AFTERNOON.
PORTIONS OF THE CWA EAST OF I 65 WILL BE ON THE PERIPHERY OF THE
RIDGE...HOWEVER ENOUGH INHIBITION FROM SUBSIDENCE WITH H5 RIDGE
APPEARS TO BE IN PLACE TO LIMIT CONVECTIVE ACTIVITY AND HAVE REMOVED
SLIGHT CHANCES FOR A THUNDERSTORM FROM THE GRIDS. IT APPEARS THAT
WEAK FRONTAL BOUNDARY THAT WAS GOING TO STALL OUT OVER THE REGION
WILL BE WASHED OUT BY THIS TIME SO NO REAL TRIGGER APPEARS TO EXIST
OTHER THAN SFC HEATING. CANNOT COMPLETELY RULE OUT A THUNDERSTORM...
HOWEVER WEAK CAP AND LACK OF A TRIGGER GIVES ENOUGH CONFIDENCE TO
MAKE THE FORECAST DRY. HIGH TEMPERATURES ARE EXPECTED TO BE WARMER
THAN SUNDAY WITH THE MERCURY PEAKING IN THE UPPER 80S OVER THE
BLUEGRASS TO THE LOWER 90S WEST OF I 65. LOWS ON MONDAY NIGHT WILL
RANGE FROM THE MID 60S IN THE BLUE GRASS TO THE UPPER 60S WEST OF I
65.

TUESDAY WILL BRING A STRONGER INFLUENCE FROM THE UPPER RIDGE AS
IT CENTERS NEAR THE REGION AND H85 TEMPS WARM TO NEAR 20 C. EXPECT
LITTLE IN THE WAY OF SKY COVER SO EXPECT OPTIMAL SFC HEATING
CONDITIONS. THIS WILL PUT THE MERCURY SOLIDLY IN THE LOW TO MID 90S.
COULD EVEN FLIRT WITH SOME 96 AND 97 DEGREE READINGS IN OUR
SOUTHWESTERN CWA. WEDNESDAY WILL BRING CONTINUED INFLUENCE FROM THE
UPPER RIDGE HOWEVER THE AXIS WILL MAKE ITS WAY EAST OF THE
APPALACHIANS BY THIS TIME. EXPECT SLIGHTLY MORE SKY COVER BY
WEDNESDAY AS GULF MOISTURE ON THE BACK SIDE OF THE UPPER RIDGE
SLIDES INTO THE AREA FROM THE SOUTHWEST. HAVE GONE ONLY SLIGHTLY
COOLER WITH HIGHS TO ACCOUNT FOR MORE SKY COVER AS H85 TEMPS AROUND
20 C CONTINUE. EXPECT THE MERCURY AROUND 90 IN THE BLUE GRASS WITH
HIGHS UP TO 95 OVER THE WESTERN CWA.

PREVIOUS DISCUSSIONS HAD HINTED AT THE LACK OF A TELLING SUBSIDENCE
INVERSION ON FORECAST SOUNDINGS WITH UPPER RIDGE IN PLACE. 12Z NAM
FORECAST SOUNDINGS NOW SHOW MORE REASONABLE INHIBITION THAT BETTER
MATCHES THE ENVIRONMENT/PATTERN WE WILL BE IN. THIS ADDS CONFIDENCE
THAT WE WILL STAY DRY THROUGH MID WEEK AND THAT MEDIUM RANGE MODELS
ARE JUST NOT PICKING UP ON IT ALL THAT WELL.

THURSDAY - SATURDAY...

UPPER LEVEL RIDGE WILL BREAK DOWN TOWARD THE END OF THE WEEK AS
SHORTWAVE SCOOTS ACROSS THE HUDSON BAY AND ASSOCIATED SURFACE LOW
DRAGS A FRONTAL BOUNDARY NEAR THE AREA. THIS BOUNDARY IS EXPECTED TO
STALL JUST NORTH OF THE CWA AND WILL BRING A MORE UNSETTLED PATTERN
BACK IN THE FORECAST. HAVE CONTINUED THE MAINLY DIURNAL TREND OF
ISOLATED TO SCATTERED CONVECTION FROM THURSDAY THROUGH SATURDAY AS
FRONTAL BOUNDARY REMAINS STALLED. HAVE KEPT CHANCES FOR PRECIPITATION
PRETTY GENERAL FOR NOW DUE TO UNCERTAINTY OF EXACTLY WHERE BOUNDARY
WILL SET UP...HOWEVER BEST CHANCES FOR CONVECTIVE ACTIVITY APPEAR TO
BE ALONG AND NORTH OF THE I 64 CORRIDOR. EXPECT A SLIGHT COOL DOWN
DURING THIS TIME PERIOD AS WELL ALTHOUGH TEMPS SHOULD STAY ABOVE
NORMAL AS WE STAY ON THE SOUTH SIDE OF THE BOUNDARY. HIGHS ON
THURSDAY WILL RANGE FROM THE UPPER 80S IN THE NORTH CLOSE TO THE
FRONT TO AROUND 90 IN SOUTH CENTRAL KENTUCKY. BY SATURDAY...HIGH
TEMPS WILL HAVE COOLED TO MID 80S IN THE NORTH TO THE UPPER 80S
ACROSS THE SOUTH.

&&

.AVIATION (18Z TAF ISSUANCE)...

STRONG MCS IS APPROACHING BWG AT THIS TIME...WINDS WILL GUST OUT OF
THE NORTHWEST AT LEAST 35 KNOTS STARTING AROUND THE BEGINNING OF
THIS TAF PERIOD. CAN ALSO EXPECT LOWER VIS AND CIG /TEMPORARY IFR
VIS/. ONCE THIS PASSES...CONDITIONS SHOULD IMPROVE THROUGH THE REST
OF THE TAF PERIOD...WITH GENERALLY LIGHT NORTHERLY WINDS EXPECTED.

OTHER TAF SITES...EXPECT SHOWERS AND ISOLATED THUNDERSTORMS TO BE
POSSIBLE THROUGH THE AFTERNOON. WILL LEAVE VCTS AND CB GROUP IN THE
SDF AND LEX TAFS FOR THIS AFTERNOON. ALL ACTIVITY SHOULD BE ENDING
BY LATE EVENING AS THE FRONT MOVES THROUGH ALL TAF SITES. AS THE
FRONT PASSES...WINDS WILL SHIFT TO THE NORTH-NORTHWEST FOLLOWED BY
AN INFLUX OF DRIER AIR.
