AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
200 PM CDT SAT JUN 17 2000

LATEST MSAS HOURLY SURFACE DATA REVEALS 70F PLUS TDS POOLING ACROSS
WKY...AHEAD OF COLD FRONT WHICH LAYS IN NE-SW FASHION ALONG LOWER OH
RIVER VALLEY. WEAK PERTURBATIONS NOTED RIDING ALONG BOUNDARY...MAY
BE HELPING INITIATE TROPICAL CONVECTION INCREASING OVER WKY.
MEANWHILE...PCPN WHICH PRODUCED HEAVY RAINS EARLY NOW BECOMING MORE
SCT ON COLD SIDE OF BOUNDARY.

12Z RUN OF ETA/AVN BEGINNING TO COME INTO AGREEMENT ON MOVEMENT OF
FRONT...WHICH IS MAIN FORECAST CHALLENGE. INDICATIONS ARE THAT
CONVECTION WL CONTINUE TO BE DIURNALLY DRIVEN OVER WKY...WHERE
LATEST FFG VALUES REMAIN HIGH. AS FRONT IS DRAGGED SLOWLY/SLOWLY S AND
E...BIG QUESTION IS WHETHER OR NOT PCPN AREA WL DEVELOP AND OVERRUN
BOUNDARY LIKE IT DID LAST NIGHT. BOTH ETA/AVN AGREE THAT THIS WL
OCCUR AGAIN TONIGHT...AND THOUGH QPF VALUES ARE NOT AS HIGH...TRAINING
OVER SATURATED GROUNDS WHICH HAVE ALREADY RECEIVED UP TO 5 OR 6
INCHES IN SOME NRN PTNS SIL WL ALLOW FFG VALUES TO BE EASILY
EXCEEDED (MAINLY NRN 1/2 FA).

AVN/ETA LIKEWISE AGREE FRONT WL EVENTUALLY BE DRAGGED OFF TO THE
EAST W/LONG WAVE TROF PASSAGE. THIS SHOULD PRECLUDE SRN 1/2 FA FM
BEING INCLUDED IN FFA ATTM...AND SO WL CONTINUE TO HOLD AND MONITOR
DEVELOPMENTS THERE. WL KEEP FAIRLY HIGH POP TONIGHT/EARLY SUN...TIL
FRONT IS DRAGGED EAST. THEN UPPER RIDGE BUILDS OVERHEAD...WHICH
SHOULD YIELD EARLY WEEK REPRIEVE IN WET WX PATTERN.

WARMER FWC PERFORMED WELL ON WARM SECTOR HIGHS YDAY...BUT COOLER FAN
DID BETTER W/LAST NIGHTS LOWS IN COLD SECTOR. LTL DIFFERENCES NOTED
W/12Z FWC/FAN GUIDANCE AS MODELS BECOME MORE IN SYNC...AND WL
THEREFORE GENERALLY ACCEPT THEIR NOS.

.PAH...FLASH FLOOD WATCH TONIGHT...ROUGHLY ALONG AND NORTH OF A LINE
FROM VAN BUREN MISSOURI TO OWENSBORO KENTUCKY.
