The episode as NWS LSX wrote it up.
An upper level disturbance moved through the area colliding with numerous old outflow boundaries. This helped to trigger showers and thunderstorms. Some of the storms remained fairly stationary and persisted for several hours, producing very high rainfall amounts and flash flooding. Some isolated severe events occurred as well.
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 St. Louis, MO wrote its last area forecast discussion before the first event at Jun 23, 2:24 PM CST, 2 hours 31 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 324 PM CDT SUN JUN 23 2013 .SHORT TERM...(TONIGHT AND MONDAY) ISSUED AT 303 PM CDT SUN JUN 23 2013 COMPLICATED FORECAST FOR TONIGHT WITH NUMEROUS DIFFERING SOLUTIONS AMONG THE DETERMINISTIC AND CONVECTION ALLOWING MODELS. THE MAIN FOCUS IN THE NEAR TERM IS ON THE LONG-LIVED CONVECTIVE BOUNDARY AND MCS NOW MOVING ACROSS NE MO INTO CENTRAL MO. THIS BOUNDARY IS MOVING INTO A REGION OF VERY UNSTABLE AIR FROM WEST CENTRAL IL ACROSS MO WHICH BECOMES MORE STABLE IN SOUTH CENTRAL IL. INDICATIONS ARE THAT IT SHOULD CONTINUE TO MAINTAIN TO SOME DEGREE OF ITS IDENTITY AS IT PROGRESSES SEWD ALTHOUGH RADAR SUGGESTS THAT IN SOME PORTIONS OF THE LINE THE COLD POOL SHEAR IS OVERWHELMING THE WEAK ENVIRONMENTAL SHEAR AND THE ORGANIZATION IS MARGINAL...AS THE OUTFLOW RACES OUT AHEAD AS IT ENCOUNTERS WELL MIXED AIR. OVERALL THOUGHTS IS THAT IT WILL MOVE SEWD THROUGH THE LATE AFTERNOON AND BE WEAKENING BY EARLY EVENING. THE ONE CAVEAT IS IF CONVERGENCE CAN BE MAINTAINED ON THE WESTERN FLANK ACROSS WESTERN MO THEN THE LONGEVITY INTO THE EVENING MAY BE GREATER THROUGH CENTRAL MO. BEYOND THIS CURRENT SYSTEM MAY EVOLVE UPSTREAM LATER THIS EVENING ACROSS NORTHERN KS/SRN NEBRASKA AND MOVE ESEWD IMPACTING NRN MO OVERNIGHT AND INTO MONDAY MORNING. THE REMNANT BOUNDARY FROM THIS OVERNIGHT ACTIVITY COULD THEN PROVIDE FURTHER FOCUS FOR STORMS ON MONDAY PRIMARILY ACROSS THE NORTHERN HALF OF THE CWA. GLASS .LONG TERM...(TUESDAY THROUGH NEXT SUNDAY) ISSUED AT 303 PM CDT SUN JUN 23 2013 IT STILL APPEARS THAT ON TUESDAY WARMING OF THE LOW-MID LEVELS SHOULD EFFECTIVELY CAP SURFACE BASED THUNDERSTORM DEVELOPMENT AND RESULT IN HOTTER TEMPERATURES. THE HEAT WILL PERSIST IN THE ABSENCE OF THUNDERSTORMS THROUGH THURSDAY ALTHOUGH NOW THE MODELS ARE SHOWING AN INITIAL WIND SHIFT/WEAK FRONT MOVING THROUGH THE AREA WEDNESDAY AFTERNOON/EVENING THAT WILL BE ACCOMPANIED BY SOME MID LEVEL COOLING AN A RENEWED CHANCE OF THUNDERSTORMS AFTER THE BRIEF LULL. THE MAIN COLD FRONT WILL THEN MOVE THROUGH THE AREA ON THURSDAY NIGHT/FRIDAY BRINGING A CHANCE OF THUNDERSTORMS AND USHERING COOLER AND DRIER AIR INTO THE REGION FOR THE WEEKEND. GLASS && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON) ISSUED AT 1244 PM CDT SUN JUN 23 2013 STILL HARD TO PIN DOWN COVERAGE AND TIMING OF STORMS THIS AFTERNOON AND EARLY EVENING.
