NWS Louisville, KY wrote its last area forecast discussion before the first event at Sep 21, 1:29 PM EST, 2 hours 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 229 PM EDT MON SEP 21 2009 .SHORT TERM (TONIGHT AND TUESDAY)... THE FORECAST SETUP REMAINS SIMILAR TONIGHT AND THROUGH MOST OF TUESDAY AS IT HAS BEEN THE LAST DAY OR TWO. A MID LEVEL TROUGH CONTINUES TO SIT OVER THE UPPER MIDWEST INTO THE LOWER MISSISSIPPI VALLEY. WAVES OF ENERGY WILL CONTINUE TO ROTATE THROUGH THE FLOW AND WITH SOUTHERLY FLOW GULF MOISTURE WILL CONTINUE TO STREAM INTO THE REGION. THE TROUGH HAS PROGRESSED EASTWARD SOMEWHAT FROM YESTERDAY SO THE BULK OF PRECIPITATION TODAY HAS STAYED MAINLY ACROSS EASTERN PORTIONS OF THE FORECAST AREA KEEPING SOUTHERN INDIANA AND WEST CENTRAL KY MAINLY DRY. SHOWERS WERE INCREASING ACROSS THE REGION THIS AFTERNOON HOWEVER IN RESPONSE TO SOME INCREASING INSTABILITY AND A STRENGTHENING UPPER LEVEL JET OVER THE REGION. EXPECT THAT AT LEAST SCATTERED SHOWERS WILL STICK AROUND OVERNIGHT GIVEN THE MOIST AIRMASS WITH OHX MORNING SOUNDING SHOWING PWAT VALUES OF AROUND 1.80 INCHES...HOWEVER SOME DRIER AIR AND SUBSIDENCE WILL NOSE INTO CENTRAL KENTUCKY TONIGHT..AS NOTED BY WV IMAGERY...AS THIS SYSTEM BEGINS TO LIFT OUT OF THE REGION AN UPPER LEVEL RIDGE BEGINS TO BUILD WESTWARD ACROSS THE SOUTHEAST STATES AND INTO THE GREAT LAKES BY TUESDAY MORNING AND THROUGH THE AFTERNOON BRING A BREAK IN PRECIPITATION TOWARD TUESDAY NIGHT AHEAD OF THE CLOSED LOW SYSTEM OVER THE CENTRAL PLAINS. THEREFORE...LOWERED POPS...KEEPING ONLY SCATTERED SHOWERS AND ISOLATED THUNDER IN THE FORECAST THROUGH TUESDAY AFTERNOON. AS WITH THE LAST FEW DAYS SOME SHOWERS WILL CAUSE LOCALLY HEAVY RAINFALL AND AREAS EAST OF INTERSTATE 65 WILL BE MONITORED CLOSELY TONIGHT FOR ANY FLOODING POTENTIAL. OVERNIGHT LOWS AGAIN BE WARM WITH MID TO UPPER 60S EXPECTED. HIGHS TOMORROW WILL RANGE FROM THE MID 70S TO LOW 80S. .LONG TERM (TUESDAY NIGHT THROUGH MONDAY)... TUESDAY NIGHT THROUGH THURSDAY... THE GFS HAS COME MORE IN LINE WITH THE ECMWF FOR THIS FORECAST PERIOD WITH A DEEP UPPER LEVEL CUTOFF LOW OVER THE CENTRAL PLAINS. THIS COMBINED WITH A RIDGE OFF THE EAST COAST WILL CONTINUE TO PUMP WARM AND MOIST AIR INTO THE LOWER OHIO VALLEY. A NUMBER OF WEAK FRONTS WILL MOVE FROM THE MID MISSISSIPPI VALLEY INTO THE LOWER OHIO VALLEY AND DISSIPATE. WE WILL KEEP PRECIPITATION IN ALL THE FORECAST PERIODS BUT IT LOOS AS IF THE BEST CHANCE FOR RAIN WILL BE WEDNESDAY AND THURSDAY AFTERNOON AND EVENING. HEAVY RAIN WILL AGAIN BE THE MAIN CONCERN AS BUFKIT FORECAST SOUNDINGS INDICATE PERCEPTIBLE WATER VALUES ABOVE 1.75 INCHES AND EVEN OVER 2 INCHES THURSDAY AFTERNOON. UNDER THE MOIST AIR MASS AND CLOUD COVER WE WILL SEE TEMPERATURES FROM THE MID AND UPPER 60S IN THE MORNING TO AROUND 80 DEGREES DURING THE AFTERNOON. FRIDAY THROUGH MONDAY... DURING THE LAST HALF OF THE WEEK THE AFOREMENTIONED CLOSED LOW WILL BEGIN TO SHIFT EAST AND OPEN UP. IN THE MEANTIME A NORTHEAST TROUGH WILL SHARPEN UP. SURFACE LOW PRESSURE WILL MOVE ACROSS THE EASTERN GREAT LAKES AND INTO NEW ENGLAND. THE RESULTING COOL FRONT WILL DROP INTO THE REGION AND STALL. THIS WILL CREATE AN ADDITIONAL BOUNDARY FOR STORM DEVELOPMENT FRIDAY AND SATURDAY. AN APPROACHING STRONG COLD FRONT WILL KEEP THE POSSIBILITY OF STORMS OVER THE REGION SUNDAY AND EARLY MONDAY. SO AGAIN WILL WILL CONTINUE TO MENTION POPS IN ALL PERIODS OF THE FORECAST UNTIL MONDAY AFTERNOON. TEMPERATURES UPPER 70S AND LOWER 80S WILL BEGIN TO COOL OVER THE WEEKEND WITH HIGHS ONLY IN THE LOW AND MID 70S BY MONDAY. && .AVIATION (21/18Z TAFS)... SCATTERED TO NUMEROUS SHOWERS WILL CONTINUE TO MOVE NORTHEAST ACROSS THE REGION THROUGH MUCH OF THE TAF PERIOD. WILL CARRY VCSH AND VCTS AS THE TIMING OF ANY ONE SHOWER OR THUNDERSTORM MOVING INTO A TERMINAL IS TOO UNCERTAIN AND WILL AMEND AS NEEDED. OVERCAST SKIES WILL REMAIN IN THE MVFR CATEGORY THROUGH MOST OF THE TAF PERIOD WITH CONDITIONS IMPROVE NEAR THE END OR JUST AFTER THE TAF PERIOD. LIGHT SOUTHERLY WINDS WILL CONTINUE TO PREVAIL AND VSBYS WILL REMAIN VFR THROUGH EVENING. SOME FOG COULD DEVELOP OVERNIGHT...ESPECIALLY WITH SHOWER ACTIVITY AND VSBYS WILL DROP IN THESE AREAS. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE.
