The episode as NWS TOP wrote it up.
Early morning of the 24th a line of storms formed across the area a few were able to produce severe winds. Later that evening an isolated storm produced heavy rainfall that caused flash flooding.

NWS Topeka, KS wrote its last area forecast discussion before the first event at Jul 23, 11:27 PM CST, 3 hours 23 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 1227 AM CDT FRI JUL 24 2015 ...UPDATE TO AVIATION FORECAST DISCUSSION... .SHORT TERM...(THIS EVENING THROUGH FRIDAY) ISSUED AT 230 PM CDT THU JUL 23 2015 QUIET AFTERNOON AND EVENING IN STORE FOR THE AREA. THE CUMULUS FIELD WILL LIKELY DISSIPATE LATER THIS EVENING AND WINDS REMAIN OUT OF THE EAST SOUTHEAST. CURRENT OBSERVATIONS SHOW A BOUNDARY ACROSS WESTERN NE WITH TOWERING CUMULUS ALREADY DEVELOPING. SOME OF THE MODELS ARE HINTING AT ISOLATED TO SCATTERED STORMS FORMING ALONG THIS BOUNDARY AS IT GRADUALLY MOVES EASTWARD. THESE STORMS MAY ONLY REACH NORTH CENTRAL KS AND SOUTH CENTRAL NE BEFORE WEAKENING. ONLY THE MOST RECENT RUNS OF THE HRRR KEEP THIS ACTIVITY GOING INTO CENTRAL KS. THERE IS A LOW LEVEL JET FORECAST TO STRENGTHEN TONIGHT OVER CENTRAL KS THAT VEERS THROUGH OUT THE MORNING HOURS. ISENTROPIC LIFT LOOKS TO DEVELOP OVER PORTIONS OF EASTERN KS ALTHOUGH THE SOUNDINGS SHOW RATHER DRY AIR WHERE THE LIFT IS MAXIMIZED. THE BETTER MOISTURE AND ISENTROPIC LIFT APPEARS TO BE FAR SOUTHEAST KS. THIS GIVES ME LOW CONFIDENCE IN ANY SHOWERS OR STORMS FORMING TONIGHT. HAVE GONE WITH SLIGHT POPS FOR NOW TO ACCOUNT FOR WESTERN NE CONVECTION REACHING THE AREA AND OR ELEVATED PRECIP FORMING DURING THE EARLY MORNING HOURS. THE ELEVATED WARM LAYER WILL STRENGTHEN AS WELL AS 850 MB TEMPS REACH 25-30 C BY TOMORROW AFTERNOON. SURFACE WINDS GRADUALLY VEER AS THE FRONT APPROACHES FROM THE NORTHWEST. DEW POINTS STAY IN THE MID TO UPPER 70S WITH THE HIGHEST VALUES IN FAR EASTERN KS. THE ONLY CONCERN IS THAT SOME OF THE MODELS SHOW DEEPER MIXING IN CENTRAL KS THAT NOSES INTO THE WESTERN FORECAST AREA. THIS COULD CAUSE THE DEW POINTS TO DECREASE DURING PEAK HEATING BUT WILL KEEP THE TEMPERATURES ABOVE 100. REGARDLESS IT APPEARS THE MOST OF THE AREA WILL SEE HEAT INDICES RANGE FROM 106-111, WHICH HAS PROMPTED A HEAT ADVISORY FOR TOMORROW. .LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY) ISSUED AT 230 PM CDT THU JUL 23 2015 SATURDAY AND SUNDAY...ONLY MADE SMALL ADJUSTMENTS TO PREVIOUS PRECIP FORECAST. CONVECTION ROLLING OFF THE HIGH PLAINS SATURDAY NIGHT MOVES EASTWARD ALONG THE FRONTAL BOUNDARY TRAILING ACROSS THE NORTHERN PART OF THE STATE THANKS TO THE SHORTWAVE MOVING INTO THE GREAT LAKES. LLJ FOCUSES A LITTLE BETTER TO THE WEST BEFORE VEERING WITH TIME AND CONVERGING ACROSS THE NORTHERN COUNTIES. WILL HAVE TO BATTLE AGAINST PERSISTENT CAP AT 700MB. WITH THIS PATTERN WOULD ANTICIPATE STORMS TO MOVE ALONG THE PERIPHERY AND WILL DRAW UP RAIN CHANCES AS SUCH. NAM AND GFS BRING A SECONDARY SHORTWAVE OUT OF THE WEST LATER IN THE DAY SATURDAY...WITH A LITTLE STRONGER LLJ INTO THE OVERNIGHT HOURS. WOULD LIKELY SEE A BREAK IN PRECIP IN THE MID TO LATE DAY BEFORE STORMS COME IN FROM THE WEST INTO THE OVERNIGHT HOURS...ONCE AGAIN FOCUSING BETTER TO THE NORTH. AS THIS WAVE PASSES TO THE EAST...THE RIDGE ALOFT AMPLIFIES IN ITS WAKE...AND WILL MOST LIKELY BRING AN END TO RAIN CHANCES LATER IN THE DAY ON SUNDAY. HAVE DROPPED TO JUST A SLIGHT CHANCE ON SUNDAY. CHANCES FOR RAIN AND ASSOCIATED CLOUD COVER AND COOLER OUTFLOWS WILL HAVE PERIODIC IMPACTS ON THE HEAT...HOWEVER FOR SATURDAY BETWEEN SYSTEMS THINK ITS A GOOD BET THAT HEAT INDICIES WILL RISE BACK TO ADVISORY LEVELS OVER THE SOUTHERN PARTS OF THE CWA...BUT THE NORTHERN COUNTIES COULD CATCH MORE OF A BREAK. NOT EXTENDING THE ADVISORY PRODUCT AT THIS TIME, BUT WILL LIKELY NEED TO BE FOR AT LEAST PART OF THE AREA FOR THE DAY ON SATURDAY. THINK SUNDAY WILL HAVE MORE IMPACT FROM CONVECTION NEAR THE AREA...AND DON'T CURRENTLY HAVE ADVISORY INDICES IN THE FORECAST. MONDAY-THURSDAY...UPPER LONGWAVE TROF MOVING INTO THE NORTHERN ROCKIES LATE MONDAY HELPS STRENGTHEN THE RIDGE ACROSS THE PLAINS BRINGING ANOTHER FEW HOT DAYS FOR MONDAY AND TUESDAY. NEXT FRONT ASSOCIATED WITH THAT UPPER TROF MOVES INTO THE CENTRAL PLAINS ON WEDNESDAY...BRINGING A SLIGHTLY BETTER CHANCE FOR RAIN FOLLOWED BY POTENTIALLY A NICE COOL DOWN BY LATE WEDNESDAY INTO THURSDAY. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z FRIDAY NIGHT) ISSUED AT 1224 AM CDT FRI JUL 24 2015 EXPECT VFR CONDITIONS FOR MUCH OF THE PERIOD. IT DOES NOT APPEAR THAT THE CONVECTION WILL REACH MHK BEFORE WEAKENING. 00Z NAM SOUNDINGS SUGGEST A POSSIBLE MVFR CIG AND OR VIS DEVELOPING AROUND 09Z ALTHOUGH THE BOUNDARY MAY REMAIN MIXED ENOUGH TO STAY VFR. CLOUDS FROM ONGOING CONVECTION IN NORTH CENTRAL KS MAY PREVENT MHK FROM THE POSSIBLE HAZE. && .TOP WATCHES/WARNINGS/ADVISORIES...
