The episode as NWS EAX wrote it up.
On the morning of July 11th, a small complex of thunderstorms moved southeast from Nebraska, and down the Missouri River into far eastern Kansas and western Missouri. These thunderstorms created an outflow boundary on the western flank of the precipitation shield. This outflow boundary, combined with southwest winds just off the surface, became the focus for lift. The airmass across southern Kansas during the mid morning hours became very warm and unstable, which helped feed deep thunderstorm development over the Kansas City metropolitan area and points east. Rainfall rates were in excess of 2 inches per hour, with rainfall totals in the Kansas City area, ranging from 1 to 5 inches. This created urban flooding in some of the typical areas, such as Southwest Boulevard, Westport Avenue, and portions of the Plaza area. This rainfall created minor flooding on some area rivers and streams.
In addition to the heavy rainfall experienced, one thunderstorm over the south Kansas City area, intensified extremely fast. In a matter of 10 to 15 minutes, a strong core of rain and hail was lifted to between 30,000 and 40,000 ft high in the atmosphere, and just as quickly collapsed over the Hickman Mills and Ruskin Heights area of south Kansas City. Extensive tree damage was reported in a couple square mile area, with an estimated 1000 trees damaged or destroyed. Trees and trees limbs falling on power lines created extensive power outages, with around 29,000 residents without power after the height of the storm.
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 Kansas City, MO wrote its last area forecast discussion before the first event at Jul 11, 5:51 AM CST, 2 hours 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 651 AM CDT SUN JUL 11 2010 ...UPDATED AVIATION DISCUSSION... .DISCUSSION... EARLY THIS MORNING...AN ELONGATED S/W TROUGH OVER NEBRASKA EMBEDDED IN BROAD WESTERLY FLOW ALOFT CONTINUED TO SUPPORT A WEAK MCS ACROSS SOUTHEASTERN NE. THROUGH DAYBREAK...EXPECTING THIS MCS TO CONTINUE TO WEAKEN AS IT PUSHES SE INTO THE NORTHERN CWA...AS INSTABILITY RAPIDLY DECREASES FURTHER EAST. THE MAIN CONCERNS IN THE SHORT TERM ARE FOCUSED ON THE POTENTIAL FOR CONVECTION TODAY THROUGH TUESDAY...THEN TRANSITIONING TO A RAPID WARMUP BY WEDNESDAY. FOR TODAY...OPERATIONAL MODELS ARE REALLY OF NO STRONG HELP...AS CONVECTIVE FEEDBACK CONTINUES TO PLAGUE FCST DETAILS. THE 00Z NAM AND TO SOME DEGREE THE 00Z GFS HAVE BOTH STRUGGLED MIGHTILY OVERDEVELOPING THE H50 S/W CURRENTLY MOVING ACROSS NE. THE OVER DEVELOPMENT OF THIS WAVE IS LEADING TO POOR RESOLUTION OF BOUNDARY LAYER FEATURES AND THUS SEVERELY IMPACTING THE FCST BEYOND TODAY. ATTM...PREFER A BLEND OF THE LOWER RESOLUTION ECMWF/GEM...WITH SOME MESOSCALE SUPPORT FROM THE NSSL-WRF AND A SLIGHTLY IMPROVED 06Z NAM. THIS SAID...INITIAL CONVECTION THIS MORNING SHOULD PUSH A LITTLE FURTHER SE INTO THE CWA THROUGH DAY BREAK ONLY SLOWLY CRAWLING INTO NORTHERN MO. POTENTIAL DOES EXIST FOR THIS ACTIVITY TO REDEVELOP AS IT MOVES A LITTLE FURTHER SOUTH. MEANWHILE...THE EVENTUAL PASSAGE OF A SFC TROUGH STILL RESIDING WELL NW ACROSS NORTH CENTRAL NE AND CENTRAL SD AND ITS IMPACTS REMAIN IN QUESTION. FEEL THAT SOME UNCERTAINTY EXISTS TO THE AMOUNT OF CONVECTIVE DEBRIS THAT WILL REMAIN OVER THE CWA TODAY WHICH COULD HAMPER AVAILABLE INSTABILITY. NEVERTHELESS THIS S/W OVER NE IS EXPECTED TO PIVOT FAIRLY QUICKLY TODAY WITH THE MAIN ENERGY PASSING THROUGH NORTHERN MO...AND A TRAILING TROUGH AXIS INTO CENTRAL KS. SHOULD MODEL PROJECTIONS OF 1500-2000 J/KG MLCAPE COME TO FRUITION...DECENT SHEAR PROVIDED BY A ABNORMALLY STRONG MID-LVL JETLET WOULD PROVIDE SOME SUPPORT FOR STRONG TO PERHAPS SEVERE DEVELOPMENT RATHER EARLY IN THE AFTN AS THE FRONT BEGINS TO SURGE SE A BIT. SOUNDINGS APPEAR MINIMALLY CAPPED...WITH INHIBITION ALREADY NON- EXISTENT BY NOON. WOULD EXPECT THE POTENTIAL FOR INITIAL VERY SCT SUPERCELL DEVELOPMENT...WITH STORMS CONGEALING INTO MULTI-CELL CLUSTERS WITH DRY POCKET OF AIR ALOFT SUPPORTIVE OF DAMAGING WINDS. FZING LVLS REMAIN FAIRLY HIGH...BUT ADEQUATE SHEAR ALOFT MAY SUPPORT LARGER HAIL. DUE TO THE SPEED AND EASTWARD PROGRESSION OF THE S/W STORMS SHOULD PROGRESS FAIRLY RAPIDLY SE THROUGH THE AFTN...WITH LOWER POPS EXPECTED IN THE EVENING AS SUBSIDENCE ARRIVES. FOR MONDAY...REALLY FEEL THAT MUCH OF MONDAY SHOULD BE DRY AS THE REGION SHOULD BE UNDER S/W RIDGING. HAVE TRIED TO TRIM BACK POPS...WHICH MAY BE TRIMMED BACK FURTHER IN LATER FCSTS. TEMPS SHOULD RECOVER A BIT ON MONDAY WITH A BIT MORE SUNSHINE...WITH READINGS SLIGHTLY BLO NORMAL. FOR MON NIGHT...ANOTHER RATHER PROGRESSIVE S/W TROUGH WILL ZIP THROUGH THE CENTRAL PORTIONS OF THE COUNTRY. AS THIS S/W PASSES OVER THE WESTERN PLAINS IT SHOULD DEVELOP CONVECTION MON AFTN AND EVE ALONG THE STALLED FRONT IN SOUTHERN KS AND SOUTHERN MO. AN MCS WILL LIKELY DEVELOP AND MOVE EASTWARD...WITH THE FAVORED AREA JUST SOUTH OF THE CWA. FURTHER NORTH THERE MAY BE ADDITIONAL CONVECTION...BUT AREAL COVERAGE WOULD SUGGEST ONLY SCT WORDING ATTM. TUESDAY AND WEDNESDAY...A RATHER RAPID AND STRONG WARMUP WILL BE ON TAP AS MID-LVL RIDGING POPS UP IN THE CENTRAL PART OF THE COUNTRY AHEAD OF STRONGER UPR TROUGH DIGGING INTO THE NORTHERN ROCKIES. READINGS ON TUESDAY WILL CLIMB INTO THE UPR 80S...LIMITED BY A SLOW RETURN OF SOUTHERLY SFC WINDS. AFTER WHATS EXPECTED TO BE A VERY WARM OVERNIGHT PERIOD TUE NIGHT...STRONG RETURN FLOW WILL PUSH THE NOSE OF A +24C TO +26C H85 THERMAL RIDGE OVERHEAD BY WED MORNING. STRONG MIXING SHOULD PUSH READINGS INTO THE LOWER 90S...ALSO PUSHING HEAT INDEX READINGS INTO THE LOWER 100S. THURSDAY...HAVE BUMPED UP POPS A LITTLE FURTHER FOR LATE WED NIGHT INTO THU AS MODELS REMAIN IN STRONG AGREEMENT IN EDGING A SFC FRONT TOWARDS THE AREA WITH MOISTURE POOLING AHEAD OF THE FRONT. DUX && .AVIATION... FOR THE 12Z TAFS...LINE OF ELEVATED CONVECTION NORTHWEST OF THE TERMINALS CONTINUES TO SLOWLY INCREASE IN COVERAGE AND INTENSITY THIS MORNING ALONG THE NOSE OF DEEPER GULF MOISTURE AND APPROACHING INSTABILITY AXIS. THE INITIAL WAVE OF THUNDERSTORMS...ACCOMPANIED BY BRIEF IFR CONDITIONS...WILL WORK ACROSS THE TAF SITES DURING THE NEXT COUPLE OF HOURS (BEGINNING WITH STJ MOMENTARILY). EXPECT WARM FRONTAL PASSAGE TO OCCUR EARLY THIS AFTERNOON IN THE WAKE OF THIS ACTIVITY...WITH ADDITIONAL STRONG STORMS POSSIBLE LATER THIS AFTERNOON ONCE THE AIRMASS RECOVERS. STORMS MAY BE ACCOMPANIED BY LARGE HAIL/DAMAGING WINDS BEFORE A WEAK FRONTAL PASSAGE ENDS THE THREAT OF PRECIPITATION THIS EVENING WITH A WIND SHIFT INTO THE LIGHT NORTH.
