NWS Paducah, KY wrote its last area forecast discussion before the first event at Jun 17, 7:47 AM CST, 3 hours 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 847 AM CDT THU JUN 17 2010 .UPDATE... UPDATED PUBLIC FORECAST DISCUSSION. && .DISCUSSION... UPDATED POPS/WX/QPF GRIDS FOR ONGOING PRECIP IN WEST KY AND ALSO FOR AREA OF THUNDERSTORMS AROUND ST. LOUIS MOVING IN OUR DIRECTION. PRETTY MUCH SCT TO NUMEROUS SHOWERS AND STORMS ONGOING FROM THE LAKES EASTWARD TO THE EDGE OF THE CWA. MOST INTENSE STORMS NEAR THE TN BORDER. THERE HAS BEEN SOME ISOLATED REDEVELOPMENT BEHIND THIS AREA OF ACTIVITY...BUT WHAT BEARS WATCHING IS THE RAPIDLY INTENSIFYING STORMS SOUTH OF ST. LOUIS. THEREFORE HAVE UPPED POPS ESPECIALLY IN SOUTHERN IL TO ACCT FOR THEIR APPROACH. ADJUSTED THE AFTERNOON POPS UP AS WELL. LOOKS LIKE WE WILL BECOME VERY UNSTABLE BY AFTERNOON...ESPECIALLY ACROSS SOUTHEAST MISSOURI...AND A GOOD PART OF SOUTHERN ILLINOIS AND WEST KENTUCKY. WITH THE LOWER DEWPOINTS ACROSS OUR FAR NORTHEASTERN SECTIONS...MODELS ARE NOT AS ROBUST WITH INSTABILITY PARAMETERS UP IN THE EVV TRI STATE AREA...SO HAVE LOWEST POPS UP THERE. ALL UPDATED PRODUCTS ARE OUT. PREVIOUS DISCUSSION...(ISSUED AT 259 AM) LARGE SCALE FLOW FORECAST IS FOR WEAK RIDGING OVER THE SOUTHERN CONUS. THE CENTER OF THE RIDGE SHIFTS FROM THE CENTRAL PLAINS ON SATURDAY TO THE LOWER OHIO VALLEY BY LATE MONDAY. IN THE SHORT TERM A WEAK MCV CAN BE SEEN IN IR LOOP OVER SOUTHERN MISSOURI BROUGHT ABOUT FROM LAST NIGHT/S CONVECTION. THIS IS REFLECTED AT 500MB WITH A WEAK SHORT WAVE. THESE FEATURES AND WARM AIR ADVECTION HAVE ALREADY DEVELOPED ISOLATED CONVECTION EARLY THIS MORNING. IN THE WEAK FLOW UNDERNEATH THE RIDGE...THIS FEATURE WILL MOVE ACROSS THE AREA TODAY. BLENDED TPW AND PROFILER DATA SHOWS THE DEEPER MOISTURE RETURNING TO SOUTHEAST MISSOURI AT THE CURRENT TIME AND THIS TREND SHOULD CONTINUE OVER THE QUAD STATE AREA DURING THE NEXT 24 HOURS. INSTABILITY WILL BE QUITE HIGH TODAY...WITH THIS SPC HAS OUTLOOKED MOST OF THE AREA IN A SLIGHT RISK WITH DAMAGING WIND GUSTS THE MAIN THREAT. WITH THE HEAT/HUMIDITY AND SOME ADDITIONAL LIFT PER ABOVE...EXPECT SCATTERED THUNDERSTORMS TODAY ESPECIALLY OVER SOUTHEAST MISSOURI. THIS FOCUS AREA LOOKS TO SHIFT MORE INTO INDIANA AND KENTUCKY ON FRIDAY. ON SATURDAY...A WEAK FRONT IS EXPECTED TO MOVE SOUTH AND STALL ALONG THE I-64 CORRIDOR SO WILL HAVE A SMALL CHANCE OF THUNDERSTORMS IN THAT AREA. THE MAIN QUESTION THEN BECOMES HOW FAR SOUTH WILL THE BOUNDARY GO. ALL MODELS ARE RATHER AGGRESSIVE AND PUSH THE FRONT THROUGH BY LATE MONDAY. THE FRONT THEN APPEARS TO WEAKEN BY TUESDAY WITH THE HEAT AND HUMIDITY RETURNING. NOT SURE ON THE SOUTHWARD EXTENT OF THE FRONTAL MOVEMENT AT THIS TIME...BUT THE DISSIPATION SEEMS REASONABLE BASED ON OVERALL UPPER LEVEL RIDGE FORECAST PER ENSEMBLES. && AVIATION... CONDITIONS WILL BE PREDOMINANTLY VFR AT ALL AREA FORECAST TERMINALS THROUGH THE PERIOD. THE FIRST WAVE OF THUNDERSTORMS HAS SHIFTED EAST OF KCGI AND KPAH...AND SHOULD BE REDUCED TO NOTHING MORE THAN LIGHT SHOWERS OR SPRINKLES IF IT EVER REACHES KEVV AND KOWB LATER THIS MORNING. ISOLATED DIURNALLY DRIVEN THUNDERSTORMS ARE POSSIBLE FROM LATE MORNING THROUGH THE AFTERNOON AT ALL TAF SITES. WINDS WILL BE LIGHT AND SOUTHERLY AT KCGI AND KPAH...VARIABLE AT KEVV AND KOWB. .&& .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE. IN...NONE. &&
