Area forecast discussion, Aug 10, 2:15 PM EST, 3 hours 7 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 315 PM EDT MON AUG 10 2009 .SHORT TERM (TONIGHT AND TOMORROW)... SCATTERED THUNDERSTORMS HAVE DEVELOPED MAINLY ACROSS THE NORTHERN HALF OF THE FORECAST AREA THIS AFTERNOON. WITH AMPLE MOISTURE AND INSTABILITY A FEW OF THESE STORMS HAVE DEVELOPED WITH ELEVATED HIGHER REFLECTIVITY CORES. IN ADDITION A LINE OF STORMS IS FORMING ACROSS A BOUNDARY IN SOUTHERN INDIANA AND THIS WILL SLOWLY SAG SOUTHWARD. SHOWERS AND THUNDERSTORMS WILL CONTINUE THIS AFTERNOON AND EVENING ACROSS THE AREA. WITH PWAT VALUES AROUND TWO INCHES EXPECT THAT ALONG WITH SMALL HAIL OR GUSTY WINDS ANY STORMS THAT DEVELOP WILL HAVE POTENTIALLY BRIEF HEAVY RAINFALL. AS THE DAYTIME HEATING WANES TONIGHT EXPECT THAT CONVECTION WILL BEGIN TO DIE OFF...THOUGH CANNOT RULE OUT AN ISOLATED SHOWER OR THUNDERSTORM OVERNIGHT. TOMORROW A THUNDERSTORMS ARE AGAIN EXPECTED AS A COLD FRONT TRAVERSES THE FORECAST AREA. THE ATMOSPHERE LOOKS TO HAVE ENOUGH TIME TO RECOVER TONIGHT AND PWATS RETURN TO AROUND TWO INCHES BY TOMORROW AFTERNOON. THEREFORE ANY STORMS THAT FORM ARE EXPECTED TO HAVE BRIEF VERY HEAVY RAINFALL. THE STRONGEST STORMS ARE EXPECTED TO BE ACROSS MAINLY THE SOUTHERN PORTION OF THE FORECAST AREA AND THESE MAY ALSO HAVE SMALL HAIL AND GUSTY WINDS ASSOCIATED WITH THEM. WITH DEWPOINTS IN THE LOWER 70S EXPECT THE LOWS TONIGHT TO BOTTOM OUT AROUND THESE VALUES. HIGHS TOMORROW WILL BE A COUPLE DEGREES COOLER THAN TODAY DUE TO AMPLE CLOUD COVER AND COLD FRONT PUSHING THROUGH. .LONG TERM (TUESDAY NIGHT-MONDAY)... MODELS IN FAIR AGREEMENT AT START OF PERIOD WITH SHORTWAVE ACROSS CENTRAL IL TUESDAY NIGHT. CONVECTION WILL HAVE ACCESS TO PLENTY OF MOISTURE WITH PRECIPITABLE WATERS AROUND 2 INCHES. STILL...MODELS HAVE SHIFTED FOCUS FOR THE HEAVIEST RAINS TO JUST TO THE SOUTH OF OUR CWA. DO NOT WANT TO BACK OFF YET ON THE HEAVY RAINFALL WORDING IN HAZARDOUS WEATHER OUTLOOKS THOUGH GIVEN THE PARAMETERS MENTIONED ABOVE. WILL KEEP IN CHANCE OF STORM WORDING FOR THE OVERNIGHT...BUT HAVE HIGHEST POPS TO THE SOUTH. THE GFS AND ECMWF HAVE COME INTO ALIGNMENT NOW WITH PUSHING THE UPPER TROUGH THROUGH THE REGION WEDNESDAY THEN DEVELOPING A CUTOFF LOW SOUTH OF THE REGION THURSDAY. THE NAM IS KEEPING WITH ITS PREVIOUS FORECAST OF AN UPPER CUTOFF DEVELOPING ACROSS THE STATE WEDNESDAY AND REMAINING TILL FRIDAY. AGAIN...CUTOFF LOWS ARE DIFFICULT TO FORECAST IN ADVANCE...BUT THE TREND RIGHT NOW IS FOR THE MOISTURE ASSOCIATED WITH THIS LOW TO STAY TO OUR SOUTH. WILL KEEP IN HIGHEST POPS...IN THE SLIGHT CHANCE RANGE...OVER THE SOUTHERN HALF OF THE STATE FOR WEDNESDAY THROUGH FRIDAY. SATURDAY THROUGH SUNDAY...GFS AND ECMWF INDICATE THAT REGION WILL BE GENERALLY DRY AS RIDGING TRIES TO BUILD IN. DGEX HANGS ON TO AN UPPER LOW ACROSS THE STATE SATURDAY...BUT WILL CONTINUE PREVIOUS FORECAST THINKING TO KEEP US DRY FOR NOW. BY MONDAY WILL SEE SOME MOISTURE COMING UP FROM THE GULF THAT MAY BRING SHOWER CHANCES BACK INTO THE FORECAST. INHIBITING FACTOR THERE HOWEVER IS THE H5 RIDGE THAT THE GFS PARKS OVER THE TOP OF THAT MOISTURE. WILL GO WITH ISOLATED SHOWERS FOR NOW. && .AVIATION (18Z TAFS)... SCATTERED SHOWERS AND A FEW THUNDERSTORMS HAVE POPPED UP ACROSS THE AREA THIS AFTERNOON. AS AN UPPER LEVEL DISTURBANCE CROSSES THE REGION THIS AFTERNOON EXPECT MORE THUNDERSTORMS TO DEVELOP. HOWEVER...THEY WILL BE SCATTERED IN NATURE SO WILL INCLUDE VCTS IN THE TAFS FOR NOW AND AMEND AS NECESSARY. WITH SCT-BKN CU THAT HAS DEVELOPED TODAY JUST BELOW 3KFT CEILINGS WILL CONTINUE TO OSCILLATE BETWEEN VFR AND MVFR. ANY STORMS THAT DEVELOP THIS AFTERNOON HAVE THE POTENTIAL FOR VERY HEAVY RAINFALL REDUCING VISIBILITIES TO IFR FOR A BRIEF PERIOD OF TIME. WINDS WILL REMAIN MAINLY OUT OF THE SOUTHWEST THIS AFTERNOON AND COULD BE GUSTY AT TIMES. WILL SEE A BREAK IN PRECIPITATION TONIGHT WITH STORMS EXPECTED TO TAPER OFF AFTER 00-03Z. WITH WET GROUND FROM THE RAINS COULD SEE SOME LIGHT FOG TOWARDS MORNING ESPECIALLY AT LEX AND BWG. ANOTHER ROUND OF THUNDERSTORMS WILL BE IN THE FORECAST TOMORROW AS A COLD FRONT PUSHES THROUGH THE REGION WITH WINDS EXPECTED TO SWITCH AROUND TO THE WEST/NORTHWEST AS THIS PUSHES THROUGH THE REGION TOMORROW. && .LMK WATCHES/WARNINGS/ADVISORIES...
