AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
117 PM EDT THU JUN 24 2010

...UPDATED AVIATION DISCUSSION...

...FORECAST UPDATE...

AT 14Z THE COLD FRONT WAS NEAR THE OHIO RIVER WITH EVANSVILLE AND
CINCINNATI BOTH INDICATING NORTHWEST WINDS WHILE SOUTHWEST WINDS
WERE NOTED AT SDF. A FEW LIGHT SHOWERS WERE DEVELOPING NORTHEAST OF
LOUISVILLE AND EXTENDING UP TOWARD CINCINNATI. FOR THE AFTERNOON ALL
SHORT RANGE MODELS CONTINUE TO INDICATE THE BEST CHANCE FOR STORMS
WILL BE SOUTH OF THE BLUEGRASS AND WESTERN KENTUCKY PARKWAYS
GENERALLY AFTER 17Z.

FOR THIS UPDATE I WILL NOT MENTION PRECIPITATION OVER MOST OF
SOUTHERN INDIANA AND ONLY ISOLATED STORMS NEAR THE OHIO RIVER.
TEMPERATURES SOUTH OF THE FRONT WERE GENERALLY IN THE LOW AND MID
80S AND WE STILL EXPECT READINGS ACROSS SOUTHERN KENTUCKY TOP WARM
INTO THE LOWER 90S. NEAR THE FRONT TEMPERATURES WILL BE SLOW TO WARM.

.SHORT TERM (TODAY AND TONIGHT)...

REMNANTS OF WEAKENING LINEAR MCS WILL BE IN OR NEAR OUR NRN FA BY
FCST ISSUANCE TIME ALONG/JUST AHEAD OF PRE-FNTL TROF FROM CENTRAL
INDIANA INTO SRN IL. CDFNT LAGS BEHIND FROM NWRN INDIANA TO NEAR
STL.

POPS TDA DEPENDENT ON FRONTAL TIMING ENCROACHING ON INCREASINGLY
UNSTABLE AMS AND HIGH RESOLUTION GUIDANCE. OUR LOCAL WRF APPEARS TO
HAVE THE BEST HANDLE ON WEAKENING STORMS HEADED OUR WAY...SHOWING A
MIN OF ACTIVITY FROM THE OHIO RIVER INTO SRN INDIANA AT 12Z. HIGH
RES MODEL THEN INDICATES REDEVELOPMENT BEGINNING BY LATE MORNING
NEAR THE OHIO RIVER AS CONVECTIVE TEMPS IN THE MID/UPPER 80S ARE
REACHED. PRIME STORM COVERAGE SHUD BE FROM MID AFTN INTO EARLY EVE
ALONG/AHEAD OF THE FRONT FROM LEX WSW TO SOUTH OF SDF AND WELL NORTH
OF BWG. MODEL SOUNDINGS INDICATE LITTLE/NO CAP...FAIRLY STEEP LOW TO
MID LEVEL LAPSE RATES...-6 TO -10 LIFTED INDICES AND 2000-4000 J/KG
CAPE DEVELOPMENT ACRS THE SRN HALF OF OUR FA. MULTICELL PULSE
STORMS...MAINLY IN LINEAR FASHION...SHUD BE MAXED OUT FROM LATE AFTN

ACTIVITY...ESPECIALLY ACRS OUR NRN FA.

WE WILL SEE AN INFLUX OF LOWER DEWPOINTS TNGT...ESPECIALLY ACRS THE
NORTH. OVER THE SOUTH...DEWPOINTS WILL BE SLOWER TO FALL...WITH SOME
FOG DEVELOPMENT LIKELY.

.LONG TERM (MONDAY - SUNDAY)...

IN THE WAKE OF THE COOL FRONT TODAY DRIER AIR WILL FILTER INTO THE
REGION FOR THE END OF THE WORKWEEK. THOUGH HIGH TEMPS FRIDAY WILL
DROP ONLY A FEW DEGREES FROM TODAY LOWER DEWPOINTS WILL MAKE IT FEEL
LESS MUGGY THAN IT HAS RECENTLY. AS WINDS SHIFT TO THE SOUTH ON
SATURDAY TEMPS WILL REBOUND BACK INTO THE LOW 90S. HOWEVER BETTER
MOISTURE ADVECTION WILL HOLD OFF UNTIL SUNDAY WITH DEEP
SOUTHWESTERLY FLOW DEVELOPING. THEREFORE HEAT INDICES WILL REMAIN
LOWER ON SATURDAY.  FRIDAY AND SATURDAY SHOULD REMAIN DRY FOR THE
REGION. HOWEVER...WITH THE MOISTURE RETURN SUNDAY AHEAD OF THE NEXT
COOL FRONT AND TEMPERATURES WARMING INTO THE LOW TO MID
90S...SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP BY
SUNDAY AFTERNOON.

THE NEXT COOL FRONT WILL TRAVERSE THE FORECAST AREA ON MONDAY. THIS
WILL BRING THE BEST CHANCE FOR SHOWERS AND THUNDERSTORMS DURING THE
LONG TERM. BEHIND THIS FRONT AN H5 TROUGH WILL DROP FROM CANADA
INTO THE GREAT LAKES REGION BY TUESDAY. THIS TROUGH WILL SLOWLY MOVE
OFF TO THE EAST. WITH NORTHERLY FLOW ALOFT WE WILL SEE COOLER TEMPS
ACROSS THE REGION ON TUESDAY AND WEDNESDAY WITH HIGHS AROUND
SEASONAL NORMS.

.AVIATION (18Z TAF ISSUANCE)...

A COOL FRONT HAD MOVED SOUTH OF SDF AND WAS NEAR LEX AT 17Z. A LINE

GREATEST CONCENTRATION ACROSS THE BLUEGRASS REGION OF CENTRAL
