The episode as NWS LMK wrote it up.
A stalled out frontal boundary along the Ohio River provided enough instability for the development of scattered severe storms over the Bluegrass region of central Kentucky during the afternoon of September 4th.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Louisville, KY wrote its last area forecast discussion before the first event at Sep 4, 12:23 PM EST, 49 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 123 PM EDT SUN SEP 4 2011 ...UPDATED AVIATION DISCUSSION... ...FORECAST UPDATE... ACROSS THE AREA THIS MORNING A PRE-FRONTAL TROUGH WITH THE MAIN WIND SHIFT ASSOCIATED WITH THIS SYSTEM WAS PUSHING SE THROUGH CENTRAL KY. AS OF 14Z...IT WAS LOCATED FROM ABOUT LOGAN COUNTY TO FRANKLIN COUNTY IN KY. THIS TROUGH WILL CONTINUE TO PUSH SE MAKING IT THROUGH OUR AREA BY MID AFTERNOON. THE MAIN COLD FRONT AS OF 1430Z...WAS ORIENTED NE TO SW FROM NW OHIO TO SOUTHERN ILLINOIS TO CENTRAL TX. THE FRONT SHOULD PASS THROUGH THE AREA SOMETIME BETWEEN MID AFTERNOON THROUGH LATE AFTERNOON/EARLY EVENING. BETWEEN THE TROUGH AND THE COLD FRONT IS A LINE OF SHOWERS AND T-STORMS. MOST OF THESE STORMS HAVE BEEN MARGINAL SPS TYPE STORMS WITH OBSERVED GUSTS ONLY IN THE 20 TO 25 MPH RANGE. LAPSE SOUNDINGS REVEAL A LL MOISTENING TREND WHICH SHOULD CONTINUE THROUGHOUT THE DAY ALLOWING LAPSE RATES TO BECOME MORE MOIST ADIABATIC. AS A RESULT...ANY DAMAGING WIND THREAT WILL DECREASE THROUGHOUT THE DAY. ANY WINDOW OF STRONG TO MARGINALLY SEVERE WIND GUSTS WOULD BE BEST IN THE LAKE CUMBERLAND REGION FOR EARLY TO MID AFTERNOON HOURS. BASED ON CURRENT RADAR AND SATELLITE TRENDS...THE 12Z HRRR LOOKS LIKE IT HAS A PRETTY GOOD HANDLE ON CONVECTION. SUSPECT THAT THE BROKEN LINE OF SHOWERS/STORMS WILL CONTINUE TO MAKE SLOW PROGRESS SE THROUGHOUT THE REST OF THE AFTERNOON. THE HRRR DOES INDICATE SOME CONVECTIVE ENHANCEMENT STARTING AROUND 18Z OVER SOUTH CENTRAL KY SO WILL NEED TO MONITOR THAT. AS THE PREVIOUS FORECASTER MENTIONED...HEAVY RAIN WILL BECOME MORE OF A THREAT THIS EVENING AND THROUGH THE OVERNIGHT HOURS. ALTHOUGH THE DRY GROUNDS SHOULD BE ABLE TO HANDLE A GOOD SOAKING RAIN...LOCALIZED PONDING OF WATER ON ROADWAYS MAY OCCUR. AS FOR GRID CHANGES FOR THIS UPDATE...UPPED POPS IN AREAS THAT IT IS RAINING THIS MORNING/EARLY AFTERNOON. ALSO TWEAKED HIGH TEMPS DOWNWARD IN THOSE SAME SPOTS. .SHORT TERM (TODAY - MONDAY)... COMPLICATED SHORT TERM FORECAST PERIOD AS OUR AREA WILL LIE BETWEEN SIGNIFICANT UPPER TROUGH AXIS SWINGING ACROSS THE GREAT LAKES TODAY AND MOISTURE STREAMING NORTHEAST AHEAD OF TROPICAL STORM LEE TO OUR SOUTH. SYNOPTIC COLD FRONT AND MOISTURE ASSOCIATED WITH NORTHERN SYSTEM WILL ENSURE SCT TO NUMEROUS SHOWERS AND TSTMS TODAY ACROSS OUR AREA. MEANWHILE...AMOUNT OF TROPICAL MOISTURE WHICH GETS INGESTED FROM LEE INTO NORTHERN STREAM SYSTEM WILL HAVE A SIGNIFICANT EFFECT ON RAINFALL COVERAGE AND HEAVIER RAINFALL AMOUNTS OVER SOUTHERN AND EASTERN AREAS OF CENTRAL KY TONIGHT INTO MONDAY. IN THE VERY NEAR TERM...SCT TSTMS HAVE BEEN OCCURRING OVER PARTS OF W-CENTRAL KY AND TO THE NORTH AND NORTHEAST OF LOUISVILLE LAST COUPLE HOURS. SOME OF THESE CELLS HAVE PUT OUT SOME IMPRESSIVE OUTFLOW BOUNDARIES...WITH THE KY MESONET STATIONS IN WARREN AND OHIO COUNTIES EARLIER HAVING REPORTED GUSTS TO 51 MPH. NORMALLY THESE CELLS WOULD NOT BE THAT IMPRESSIVE. HOWEVER...00 UTC SOUNDINGS AT OHX AND ILN ARE VERY IMPRESSIVE WITH AN INVERTED-V SOUNDING WITH DRY ADIABATIC LAPSE RATES TO AT LEAST 700 MB AND A DRY BOUNDARY LAYER. THUS...SCT TSTMS HAVE BEEN VERY EFFECTIVE IN THEIR MICROBURST AND CONVECTIVE OUTFLOW PRODUCTION. WE HAVE ISSUED A FEW SVR WARNINGS AND A NUMBER OF SPECIAL WEATHER STATEMENTS FOR THESE CELLS. THE MAJORITY OF CELLS NOW ARE JUST OUTSIDE OUR FORECAST AREA. MODELS SUGGEST THAT THIS ENVIRONMENT WILL CHANGE DURING THE DAY TODAY. WITH MORE CLOUD COVER AND INCREASING LOW-LEVEL MOISTURE... LOW-TO0-MID LEVEL LAPSE RATES OVERALL SHOULD GRADUALLY WEAKEN SOMEWHAT TODAY. THIS IS REFLECTED IN LOWER TOTAL TOTALS INDICES LATER TODAY. HOWEVER...THE ENVIRONMENT WILL STILL BE UNSTABLE AND CONDUCIVE TO NUMEROUS TSTMS. HOWEVER...MICROBURST WIND POTENTIAL SHOULD SUBSIDE SOMEWHAT LATER TODAY...ALTHOUGH STILL CANT RULE OUT ISOLATED SVR STORMS DURING THE DAY TODAY. WHILE MULTIPLE OUTFLOW BOUNDARIES COMPLICATE THE CONVECTIVE AND SURFACE WIND FORECAST TODAY...THE SYNOPTIC COLD FRONT WILL APPROACH THE OH RIVER THIS AFTERNOON AND MOVE THRU CENTRAL KY TONIGHT. HIGH TEMPS THIS AFTERNOON WILL BE TRICKY WITH CLOUDS AND RAINFALL LIMITING THE DIURNAL RISE...AND WILL CONTINUE WITH 80S IN THE GRIDS...CERTAINLY COOLER THAN YESTERDAY...BUT ALSO MORE HUMID TODAY AHEAD OF THE FRONT. WITH K INDEX VALUES IN THE 30S TODAY AND INCREASING ATMOSPHERIC MOISTURE...TSTMS WILL BECOME INCREASINGLY MORE EFFICIENT HEAVY RAINFALL PRODUCERS...WITH LOCALLY HEAVY RAIN EXPECTED. LATE TONIGHT INTO MONDAY AS THE NORTHERN STREAM TROUGH IMPINGES ON OUR AREA AND TRIES TO PHASE SOME TROPICAL SOUTHERN MOISTURE...BOTH THE GFS AND ECMWF SHOW A NICE JET STREAK DEVELOPING OVER THE OH VALLEY AND GREAT LAKES...WITH THE RIGHT ENTRANCE REGION OVER THE TN VALLEY INTO SOUTHERN/EASTERN KY (CERTAINLY MORE LIKE A COOL SEASON SYSTEM). THIS SHOULD ENHANCE FORCING AND COULD LEAD TO PERIODS OF HEAVY RAINFALL OVER THE SOUTHEASTERN HALF OF OUR FCST AREA...IF CURRENT MODEL PROJECTIONS ARE CORRECT. CONVECTIVE-DOMINATED RAINS TODAY WILL TRANSITION MORE TO STRATIFORM-DOMINATED RAINS WITH POSSIBLE EMBEDDED CELLS LATE TONIGHT AND MONDAY. ON MONDAY...THE PRECIP SHIELD SHOULD SLIDE SLOWLY TO THE EAST. THIS WILL ALLOW SRN IND AND NORTH-CENTRAL KY TO DRY OUT...WHILE SHOWERS CONTINUE OVER EASTERN PARTS OF SOUTH-CENTRAL KY. TEMPS WILL BE MUCH COOLER WITH A NE SURFACE WIND...WITH HIGH TEMPS PROBABLY ONLY IN THE UPPER 60S AND LOWER 70S...POTENTIALLY EVEN COOLER IN THE SOUTHEAST IF RAIN AND LOW CLOUDS LINGER LONG ENOUGH. .LONG TERM (MONDAY NIGHT - SATURDAY NIGHT)... MONDAY NIGHT - SATURDAY NIGHT... BY MONDAY NIGHT...SFC FRONTAL TROUGH WILL BE WELL SOUTHEAST OF THE AREA WITH THE UPPER LOW ASSOCIATED WITH TROPICAL STORM LEE REMNANTS PUSHING NORTHWARD ACROSS THE GULF STATES. THIS UPPER LOW WILL SLOWLY MOVE TOWARDS OUR CWA AND MOVE OVERHEAD BY LATE WEDNESDAY. EURO AND GFS STILL IN GOOD AGREEMENT WITH THIS SOLUTION...AND IT APPEARS AS THE NAM IS OUT TO LUNCH AND DOES NOT EVEN BRING LEE UP THIS DIRECTION. WENT WITH THE CONSISTENT EURO/GFS AND KEEP POPS IN ACROSS AT LEAST THE SERN/SRN CWA MONDAY NIGHT-TUESDAY...AND THEN OVERSPREADING MOST OF THE AREA THROUGH THE REST OF THE EXTENDED FORECAST AS LEE IS PROGGED TO REMAIN OVERHEAD THROUGH AT LEAST THE ENTIRE WORK WEEK. BECAUSE OF THIS TEMPERATURES OVER THE CWA THROUGHOUT THE WEEK WILL HIGHLY DEPEND ON CLOUD COVER AND ASSOCIATED PRECIP...BUT HIGHS IN THE 70S AND LOWS IN THE 50S LOOKS REASONABLE. MORE BREAKS IN THE CLOUDS/PRECIP SHOULD BE THE RULE LATER IN THE WEEK AS SHOWERS WITH LEE REMNANTS BECOMES MORE SCATTERED AND LESS WIDESPREAD OVER TIME. SOUTHEASTERN SECTIONS OF CENTRAL KENTUCKY...INVOF LAKE CUMBERLAND...HAVE DESCENDED INTO SEVERE DROUGHT RECENTLY BUT THIS IS THE REGION WITH THE BEST SHOT AT SIGNIFICANT RAINFALL. RIGHT NOW THE BEST CHANCES FOR RAIN IN THE LAKE CUMBERLAND REGION APPEAR TO BE MONDAY THROUGH TUESDAY. OVER THE COURSE OF THE WEEK 2 TO 4 INCHES OF RAIN WILL BE POSSIBLE. NO SEVERE WEATHER IS EXPECTED NEXT WEEK. AS A MATTER OF FACT NOT EVEN MUCH THUNDER IS ANTICIPATED...WITH THE BEST CHANCE OF THUNDER RIGHT NOW LOOKING TO BE ON FRIDAY WITH SLIGHTLY STEEPER MID LEVEL LAPSE RATES. && .AVIATION (18Z TAF ISSUANCE)... COMPLICATED TAF PERIOD DUE TO THE TIMING OF T-STORMS...FROPA...AND MVFR FLIGHT RESTRICTIONS. A PRE-FRONTAL TROUGH HAS MADE IT THROUGH SDF/BWG ALREADY THIS AFTERNOON SWITCHING WINDS TO THE NW. IT IS SCHEDULED TO PASS THROUGH LEX VERY SHORTLY SO WILL BEGIN THE LEX TAF WITH NW WINDS. A COLD FRONT LIES TO OUR NW FROM NW OHIO TO SOUTHERN ILLINOIS TO CENTRAL TX. THIS FRONT IS PROGGED TO MOVE THROUGH THE TAF SITES BETWEEN 1 AND 6Z TONIGHT VEERING WINDS TO THE NORTH. BETWEEN THE TROUGH AND FRONT MULTIPLE BANDS OF SHOWERS/T-STORMS ARE DEVELOPING AND WILL CONTINUE THROUGH THE AFTERNOON HOURS. HAVE TRIED TO TIME -TSRA WITH MVFR VSBYS IN THE TAFS FOR THIS AFTERNOON...BUT WILL NEED TO ADJUST THIS TIMING AND POSSIBLY LOWER VSBYS IF A GOOD T-STORM CROSSES A TAF SITE. EVV/HNB HAVE EXPERIENCED 1 TO 3SM VSBYS IN T-STORMS ALREADY TODAY. AFTER FROPA PASSAGE THIS EVENING PRECIP WILL BECOME MORE STRATIFORM IN NATURE WITH ONLY AN ISLD RUMBLE OF THUNDER POSSIBLE SO WILL CONTINUE -SHRA. THE REMNANTS OF TS LEE WILL MOVE NORTH INTO OUR AREA THIS EVENING CAUSING PRECIP TO LINGER AT BWG/LEX THROUGH THE OVERNIGHT HOURS. PRECIP AT SDF SHOULD BECOME VERY SPOTTY IN NATURE AFTER 3Z TONIGHT. MVFR VSBYS/CIGS LOOK TO IMPACT ALL TAF SITES OVERNIGHT WITH CIGS DROPPING TO LOW END MVFR AFTER 3 TO 6Z. PRECIP SHOULD END WITH AN NNE WIND PICKING UP AROUND OR JUST AFTER SUNRISE INTO THE 8 TO 10 KT RANGE. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE.
