Area forecast discussion, Jun 10, 1:25 PM CDT, 2 hours 55 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 125 PM CDT WED JUN 10 1998 NOON SURFACE ANALYSIS SHOWS QUASI STATIONARY BOUNDARY EXTENDING ACROSS NORTHERN PORTIONS OF THE FORECAST AREA. NSAT SHOWS A FEW LOW CLOUDS BUT MAINLY STILL HIGH CLOUDS ACROSS THE REGION. FORECAST ISSUES REMAIN POPS AND THE NEED FOR A FLASH FLOOD WATCH. NGM SEEMS TO LINE UP BETTER AS FAR AS SURFACE FEATURES THIS MORNING HOWEVER BOTH MODELS HAVE BEEN LESS THAN RELIABLE THE PAST COUPLE OF DAYS. NEXT WAVE SET TO MOVE NORTHEAST UP THE UPPER LEVEL RIDGE TOWARD THE MID MISSISSIPPI VALLEY THROUGH TOMORROW. THIS WILL PUSH SURFACE BOUNDARY MORE NORTH. MORE NEAR TERM...LATEST ADAP DATA SHOWING EXTREMELY UNSTABLE CONDITIONS ACROSS WEST KENTUCKY. SHARP DATA THIS MORNING REVEALED MOST NOTABLY LIS/SIS -5 TO -10 AND PRECIPITABLE WATER VALUES BETWEEN 1.5 AND 2 INCHES. THOUGH NOT READILY APPARENT...AM SURE THERE ARE BOUNDARIES LEFT OVER FROM THIS MORNINGS CONVECTION TO ENHANCE THUNDERSTORM DEVELOPMENT THIS AFTERNOON AND EVENING. CURRENT FFG VALUES ONLY 1 INCH IN 3 HOURS ACROSS MOST OF SOUTHEAST MISSOURI...EXTREME SOUTHERN ILLINOIS AND ALL OF WEST KENTUCKY. WOULD LIKE TO SEE CURRENT FLASH FLOOD WATCH CONTINUED OVERNIGHT...ANY RAIN FALLING IS PRODUCING FLOOD PROBLEMS AND AGGREVATING EXISTING FLOOD PROBLEMS FROM PAST 30 HOURS. AM FLEXIBLE OVER SOUTHWEST INDIANA THOUGH THEY HAVE NOT RECEIVED THE HEAVY RAINS THAT OTHER AREAS HAVE. MO`S HAS BEEN REASONABLE WITH LOW TEMPERATURES THE PAST COUPLE OF DAYS AND WILL NOT SUGGEST ANY DEVIATION. ML

CONTINUED HIGH PRECIPITABLE WATER VALUES WILL MAKE HEAVY RAIN A DEFINITE POSSIBILITY.
