AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
300 PM EDT FRI JUN 13 2003

CLOUDS AND LACK OF FOCUSING MECHANISM HAVE LIMITED CONVECTION IN ERN
KY TODAY. MAIN CONVECTION IS IN INDIANA AND IL. THIS ASSOCIATED WITH
THE SFC FRONT AND THE THE MID/UPPER TROF OVER THE MID MS VALLEY
WHICH IS WELL DEPICTED ON LATEST SATELLITE LOOPS. LOOK FOR THIS
CONVECTION TO CONTINUE TO INCREASE THIS EVENING...AS UPPER LEVEL
SPEED MAX MOVES INTO WRN KY TONIGHT. REMAINS OF THIS CONVECTION MAY
MOVE INTO WESTERN PART OF OUR CWA LATE TONIGHT BUT IT LOOKS TO
DIMINISH BY EARLY SATURDAY MORNING. WILL FOLLOW THIS IDEA WITH BEST
POPS TONIGHT IN W TO NW PART OF FORECAST AREA.

AS THE SHORT WAVE MOVES EAST WILL SEE SFC LOW ALONG THE FRONTAL
BOUNDARY IN THE OH VALLEY MOVE EAST ALSO. SFC COLD FRONT WILL MOVE
SOUTHEAST ACROSS CWA ON SATURDAY. MAIN DIFFERENCE FROM PREVIOUS
FORECAST IS THE SLOWER MOVEMENT DEPICTED BY BOTH THE GFS AND ETA.
WHILE ANY CONVECTION THAT MAKES IT INTO OUR AREA TONIGHT WILL BE
DECREASING BY MORNING...SHOWERS AND THUNDERSTORMS SHOULD DEVELOP
ALONG THE FRONT IN SERN KY SATURDAY AFTERNOON AND EVENING.

WILL KEEP A CHANCE OF SHOWERS AND THUNDERSTORMS INTO EARLY SUNDAY
MORNING IN FAR SOUTH AND SOUTHEAST CWA WITH SLOWER FRONTAL
MOVEMENT.

.JKL...NONE.

1040 AM EDT FRI JUN 13 2003

THE ONLY MAJOR CHANGE MADE IN THIS MORNING/S FORECAST UPDATE WAS TO
LOWER POPS TO CHANCE CATEGORY. FIRST AREA OF SHOWERS DEPARTING
EASTERN KY ATTM...SO FOCUS TURNS TO THE MORE VIGOROUS SHORTWAVE
ACROSS MO/IL WHICH SLOWLY SHIFTS EAST. WITH BEST DYNAMICS REMAINING
WEST OF OUR AREA...AND NO SFC BOUNDARY ON WHICH TO FOCUS
CONVECTION...WE HAVE DECIDED TO LOWER POPS THIS AFTERNOON. POTENTIAL
FOR SVR WEATHER THIS AFTERNOON IS DEPENDANT ON AMOUNT OF CLEARING
EXPERIENCED LATE THIS AFTERNOON. LATEST MESOETA FORECAST SOUNDINGS
SUGGEST ONLY SOME BREAKS IN THE CLOUD COVER IN OUR WESTERN
ZONES...IF THIS OCCURS CAPES COULD POTENTIALLY REACH NEAR OR OVER
1500 J/KG. HOWEVER...FEEL SVR THREAT IS NOT LARGE ENOUGH TO MENTION
IN ZONES.

445 AM EDT FRI JUN 13 2003

LITTLE CHANGE IN THE OVERALL PICTURE IS SEEN INTO SATURDAY. FRONTAL
BOUNDARY REMAINS LAID OUT TO OUR NORTH...WITH THE ENTIRE AREA IN A
SOUPY AIR MASS. IMPULSES CONTINUE TO RIDE THROUGH THE FLOW...WITH
ONE CURRENTLY BRINGING DEEPER MOISTURE AND PRECIP BACK INTO THE AREA
EARLY THIS MORNING. THIS WILL LIFT OUT DURING THE DAY. HOWEVER...
DIURNAL HEATING/INSTABILITY MAY CONTRIBUTE TO RENEWED BUT LESS
CONCENTRATED ACTIVITY DURING THE AFTERNOON. FOR THE FIRST PERIOD AS
A WHOLE...PREFER LIKELY POPS. THE BEST CHANCE WILL BE EARLY...BUT
PREFER NOT TO BE TOO SPECIFIC WITH WORDS IN THE FORECAST SINCE THERE
PROBABLY WILL BE SHOWERS AND STORMS AROUND YET IN THE AFTERNOON.

MODELS BRING IN ANOTHER IMPULSE LATE TONIGHT...BUT THE ETA AND AVN
DIFFER A BIT ON THE SPECIFICS OF THE MOISTURE PATTERN. THE NGM IS
MORE SUPPORTIVE OF THE ETA PATTERN AND WILL LEAN THIS DIRECTION.
WILL USE LIKELY POPS NORTHWEST AND CHANCE SOUTHEAST. ON SATURDAY
THIS WAVE PUSHES THROUGH AND THE FRONTAL BOUNDARY ITSELF ARRIVES.
BETWEEN THESE TWO FACTORS...LIKELY POPS SEEM IN ORDER AGAIN AREA
WIDE.

AS DRIER AIR WORKS IN FROM THE NORTHWEST...ANY REMAINING SHOWERS
WILL END ON SATURDAY NIGHT. BEST CHANCE WILL BE SOUTHEAST WHERE THE
MOIST AIR MASS LINGERS LONGEST. BEYOND THIS...FINALLY LOOKS LIKE A
STRETCH OF DRY WEATHER.

IN TERMS OF SEVERE WEATHER POTENTIAL OVER THE NEXT COUPLE OF
DAYS...CAN NOT RULE IT OUT ENTIRELY...BUT CHANCES CERTAINLY LOOK
MINIMAL DUE TO WEAK LAPSE RATES...LACK OF STRONG INSTABILITY...AND
LACK OF STRONG FLOW ALOFT. WITH HIGH PRECIPITABLE WATER VALUES OF
GENERALLY ABOVE 1.5 INCHES...SOME HEAVY RAINFALL WILL BE POSSIBLE
WITH THUNDERSTORMS. HOWEVER...THIS SHOULD BE LOCALIZED.

947 PM EDT THU JUN 12 2003

SHRA ACTIVITY HAS DECREASED TO ALMOST NOTHING. SHOULD STAY THAT WAY
FOR SEVERAL HOURS BUT MODELS DO BRING IN ANOTHER WAVE TOWARDS
MORNING. WILL DECREASE POPS TO CHC CAT AND LIST TIMING FOR MORNING.
SAT PIC ALREADY HAS THIS SYSTEM IN VIEW FROM EVV TO BHM. HAVE ALSO
REDUCED SKY COVER TONIGHT BUT CLOUDS WILL ROLL BACK IN SHORTLY SO
TEMPS WIL DIP BUT FEEL NOT FAR ENUF FOR SERIOUS FOG PROBLEM.
