The episode as NWS PAH wrote it up.
A line of thunderstorms moved southeast across the Purchase area of western Kentucky, producing isolated wind damage in Mayfield. The storms were associated with a 500 mb shortwave trough moving east-southeast into the Mid-Mississippi Valley. The storms occurred south of a warm front draped across central Indiana and Illinois.

NWS Paducah, KY wrote its last area forecast discussion before the first event at Jul 26, 5:50 AM CST, 4 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 650 AM CDT SUN JUL 26 2015 .UPDATE... ISSUED AT 650 AM CDT SUN JUL 26 2015 REVISED AVIATION DISCUSSION FOR 12Z TAFS. && .SHORT TERM...(TODAY THROUGH TUESDAY) ISSUED AT 322 AM CDT SUN JUL 26 2015 SIMILAR TO YESTERDAY...MAIN NEAR TERM CONCERNS INCLUDE: (1.) THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS; AND (2.) THE BUILDING HEAT AND HUMIDITY THROUGH MID WEEK. GIVEN THE UNCERTAINTY OVER CONVECTIVE POTENTIAL AND ITS IMPACT ON TEMPERATURES...CONFIDENCE IS ONLY AVERAGE TODAY...WITH SOME IMPROVEMENT THROUGH THE REMAINDER OF THE NEAR TERM. THE UPPER LEVEL HIGH WILL REMAIN IN PLACE ACROSS THE SOUTHERN STATES THROUGH MID WEEK. IMPULSES OF ENERGY STREAMING SOUTHEAST ALONG THE NORTHERN PERIPHERY OF THIS HIGH WILL CONTINUE TO YIELD THE POTENTIAL FOR CONVECTIVE COMPLEXES AS OBSERVED IN MISSOURI OVERNIGHT. MOST HI-RES CONVECTION-ALLOWING MODELS INDICATE THAT SOME PART OF THE ONGOING MCS ACTIVITY OVER MISSOURI SHOULD MAKE IT INTO AT LEAST THE NORTHWESTERN PART OF OUR FORECAST AREA THIS MORNING. HOWEVER...I SUSPECT THESE MODELS MAY BE TOO AGGRESSIVE IN THEIR SOUTHEASTWARD DEPICTION OF SAID CONVECTION. THE THUNDERSTORM ACTIVITY SHOULD UNDERGO SOME WEAKENING AS IT MOVES FURTHER FROM ITS ORIGINATION SOURCE. THAT SAID...ANY REMNANT MCV OR BOUNDARIES MAY ACT TO SERVE AS A TRIGGER FOR NEW CONVECTION BY AFTERNOON IN THE HOT...HUMID...UNSTABLE ENVIRONMENT. WIDESPREAD SEVERE ACTIVITY IS NOT EXPECTED AT THIS TIME...BUT IN CONJUNCTION WITH SPC'S DAY 1 OUTLOOK...A FEW STRONG TO SEVERE CELLS ARE CERTAINLY POSSIBLE. A SMALL CHANCE OF THUNDERSTORMS WILL CONTINUE INTO TONIGHT AND MONDAY...MAINLY ACROSS NORTHERN PORTIONS OF SOUTHERN ILLINOIS AND INTO THE EVANSVILLE TRI-STATE AREA. AS THE UPPER LEVEL HIGH BUILDS FURTHER EAST...THE POTENTIAL FOR THUNDERSTORMS SHOULD DROP OFF BY MONDAY NIGHT AND TUESDAY. AS FAR AS TEMPERATURES ARE CONCERNED...CONVECTIVE CLOUD DEBRIS MAY IMPACT TEMPERATURES ACROSS AT LEAST A PART OF THE REGION TODAY. AS A RESULT...WE WILL NOT BE ISSUING A HEAT ADVISORY AT THIS TIME. WILL INSTEAD HANDLE ANY NEAR ADVISORY HEAT INDICES WITH A SPECIAL WEATHER STATEMENT. IF CONDITIONS CHANGE...THE DAY SHIFT CAN POP AN ADVISORY WHERE NEEDED. BY MONDAY AND TUESDAY...THE INFLUENCE OF THE UPPER LEVEL HIGH WILL BECOME MORE NOTICEABLE AS PRECIPITATION CHANCES BEGIN TO DWINDLE. HEAT AND HUMIDITY WILL TAKE HOLD WITH HIGHS IN THE LOWER 90S AND HEAT INDEX READINGS OF AT LEAST 100 TO 105 ACROSS MOST OF THE AREA. .LONG TERM...(TUESDAY NIGHT THROUGH SATURDAY) ISSUED AT 322 AM CDT SUN JUL 26 2015 AVERAGE TO ABOVE AVERAGE CONFIDENCE IN THE LONG TERM AS MODELS COMING INTO BETTER AGREEMENT ON PLACEMENT...TIMING...AND STRENGTH OF SYNOPTIC FEATURES. AT THE BEGINNING OF THE LONG TERM PERIOD...THE UPPER LEVEL RIDGE THAT WILL HAVE BROUGHT EXCESSIVE HEAT AND HUMIDITY TO THE REGION IN THE SHORT TERM PERIOD WILL BEGIN TO BREAK DOWN WITH THE APPROACH AND PASSAGE OF A BONA FIDE COLD FRONT WEDNESDAY INTO WEDNESDAY NIGHT. AS A RESULT...THE BEST PRECIPITATION CHANCES AREA-WIDE SHOULD BE DURING THAT SAME PERIOD. SMALL PRECIPITATION CHANCES MAY LINGER INTO THURSDAY MORNING OVER THE FAR SOUTHERN PENNYRILE REGION OF WEST KENTUCKY...OTHERWISE HIGH PRESSURE AT THE SURFACE OVERSPREADING THE AREA IN THE WAKE OF THE FRONT SHOULD KEEP THE REGION DRY THROUGH THE REMAINDER OF THE SHORT TERM PERIOD. TEMPERATURES AND HUMIDITIES ON WEDNESDAY WILL STILL BE VERY UNPLEASANT WITH HEAT INDEX VALUES IN THE 100-105 DEGREE RANGE BUT BEYOND THAT NORTHWEST FLOW ALOFT COMBINED WITH THE HIGH PRESSURE AT THE SURFACE SHOULD MAKE FOR A MORE PLEASANT LATTER HALF OF THE UPCOMING WEEK INTO AT LEAST THE FIRST HALF OF THE UPCOMING WEEKEND. && .AVIATION... ISSUED AT 650 AM CDT SUN JUL 26 2015 MVFR CEILINGS WILL PERSIST THROUGH MID MORNING AT MOST FORECAST TERMINALS. VISIBILITIES WILL ALSO BE RESTRICTED BY HAZE AT KEVV. MID AND HIGH CLOUDS FROM A DECAYING COMPLEX OF THUNDERSTORMS WILL BE ON THE INCREASE THROUGH THE MORNING. MUCH OF THIS ACTIVITY SHOULD DIMINISH BEFORE REACHING THE TAF SITES. HOWEVER...REMNANT ENERGY AND BOUNDARIES MAY AID IN NEW THUNDERSTORM DEVELOPMENT DURING THE AFTERNOON. GIVEN THE UNCERTAINTY THOUGH...WE HELD OFF ON MENTIONING THUNDER AT THIS TIME. WINDS WILL GENERALLY BE LIGHT AND VARIABLE THROUGH THE PERIOD. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...NONE. MO...NONE. IN...NONE. KY...NONE. && SHORT TERM...RJP LONG TERM...JP AVIATION...RJP

PORTIONS OF SOUTHEAST MISSOURI... SOUTHERN ILLINOIS...AND SOUTHWEST INDIANA STAND THE BEST CHANCE... WITH LOWER CHANCES SOUTHEAST OF THE OHIO RIVER. THE COMBINATION OF HEAT AND HUMIDITY WILL MAKE FOR UNCOMFORTABLE CONDITIONS THIS AFTERNOON ACROSS WESTERN PORTIONS OF THE REGION. PLEASE REFER TO THE SPECIAL WEATHER STATEMENT FOR MORE DETAILS. FLOODING CONTINUES ON THE MISSISSIPPI...WABASH...AND OHIO RIVERS. PLEASE REFERENCE THE LATEST RIVER FLOOD STATEMENTS FOR DETAILS. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY A SMALL CHANCE OF THUNDERSTORMS LINGERS ACROSS THE EVANSVILLE TRI- STATE AREA ON MONDAY. THE CHANCE OF THUNDERSTORMS RETURNS TO THE ENTIRE REGION WEDNESDAY AND WEDNESDAY NIGHT WITH THE PASSAGE OF A COLD FRONT. LIGHTNING AND LOCALLY HEAVY RAIN WILL BE THE PRIMARY IMPACTS. THE EXPANDING HEAT AND HUMIDITY WILL MAKE FOR EVEN MORE OPPRESSIVE CONDITIONS THROUGH MID WEEK. MOST AREAS WILL SEE MAXIMUM HEAT INDEX VALUES AROUND THE 105 DEGREE MARK...IF NOT HIGHER IN SOME LOCATIONS. SEE THE SPECIAL WEATHER STATEMENT FOR MORE INFORMATION. ALSO REFER TO THE LATEST RIVER FLOOD WARNINGS AND STATEMENTS FOR DETAILS ON RIVER FLOODING. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS NOT ANTICIPATED. RJP
