The episode as NWS IND wrote it up.
A complex of severe thunderstorms, that cause significant and widespread damaging winds known as a derecho, developed during the morning of the 29th over northern Illinois. This complex of storms quickly intensified and sped southeast through the northern half of Indiana during the afternoon. Wind gusts of 60 to 70 mph, blinding rainfall, large hail and constant lightning accompanied the derecho in central Indiana immediately north of Indianapolis. The wind gusted from 55 to 60 mph in the Indianapolis metro area as a result of the outflow boundary from these storms.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 210 PM EDT FRI JUN 29 2012 .UPDATE... THE LONG TERM SECTION HAS BEEN UPDATED BELOW. && .SYNOPSIS... ISSUED AT 350 AM EDT FRI JUN 29 2012 THE STRONG UPPER RIDGE WHICH HAS BROUGHT RECORD HEAT TO OUR REGION WILL BE DEPRESSED SLIGHTLY TO THE SOUTH THE NEXT FEW DAYS WHICH WILL ALLOW A WEAK FRONTAL SYSTEM TO REACH THE NORTHERN PORTIONS OF OUR REGION LATER TODAY BEFORE STALLING. AN WEAK UPPER LEVEL WEATHER DISTURBANCE WILL MOVE ACROSS OUR REGION THIS WEEKEND. IN THE EXTENDED...MODELS INDICATE THE UPPER RIDGE WILL BUILD NORTH ACROSS THE CENTRAL PLAINS AND MID MISSISSIPPI VALLEY WHICH WILL KEEP OUR WEATHER QUITE WARM AND DRY. && .NEAR TERM /REST OF TODAY/... ISSUED AT 941 AM EDT FRI JUN 29 2012 MAIN FOCUS WILL BE THE CONTINUED HOT TEMPERATURES AND WHETHER ANY CHANGES ARE NEEDED IN THE EXCESSIVE HEAT HEADLINES AND THUNDERSTORM CHANCES LATER TODAY ACROSS CENTRAL AND NORTHER PORTIONS. SURFACE CHARTS INDICATED A WEAK COLD FRONT WAS OVER NORTHERN ILLINOIS AND EXTREME NORTHERN INDIANA AND THIS FRONT MAY MOVE TO THE EXTREME NORTHERN PART OF OUR FORECAST AREA BEFORE STALLING OUT TODAY. THERE IS SOME POOLING OF 70 PLUS DEWPOINTS NEAR THIS FRONT AND MODELS HINT THAT SCATTERED THUNDERSTORMS WILL PROBABLY DEVELOP LATER TODAY ALONG THIS FRONT. THERE IS SOME DIFFERENCE BETWEEN MODELS ON HOW FAR SOUTH THIS OCCURS WITH THE NAM KEEPING ALL BUT FAR NORTHERN PARTS OF OUR FORECAST AREA DRY TODAY. THE GFS...RAPID REFRESH AND EURO ARE A LITTLE MORE AGGRESSIVE IN SPREADING PRECIP SOUTH ACROSS OUR REGION WHILE THE NAM/CANADIAN KEEP THINGS MORE CAPPED ACROSS OUR REGION. FOR NOW WILL TAKE A MIDDLE OF THE ROAD APPROACH WHICH WOULD INDICATE SCATTERED THUNDERSTORMS MAINLY NORTH OF INDY...WHILE FAR SOUTHERN SECTIONS STAY DRY. SPC HAS THE NORTHERN HALF OF OUR REGION IN A SLIGHT RISK OF SEVERE WEATHER LATER TODAY AND EARLY TONIGHT. AS FAR AS TEMPERATURES TODAY NORTHERN SECTIONS WILL BE A LITTLE COOLER AS 850 MB TEMPERATURES ARE IN THE LOWER 20S AND THERE WILL BE MORE CLOUDS AND A FEW THUNDERSTORMS TODAY. MEANWHILE SOUTHERN AREAS WILL BE ALMOST AS HOT AS YESTERDAY. WITH HIGHS IN THE MIDDLE TO UPPER 90S ACROSS OUR NORTH WILL DOWNGRADE EXCESSIVE HEAT WARNING TO A HEAT ADVISORY NORTH OF INDY TODAY...WHILE LEAVING MOST AREAS FROM INDY AND SOUTH STILL IN AN EXCESSIVE HEAT WARNING. EVEN IN THE SOUTH...HEAT INDEX VALUES MAY NOT QUITE REACH 110 AS DRIER AIR WILL SPREAD INTO OUR SOUTHERN SECTIONS LATER TODAY. BUT IT WILL BE CLOSE ENOUGH TO CONTINUE THE EXCESSIVE HEAT WARNING. && .SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/... ISSUED AT 350 AM EDT FRI JUN 29 2012 ...NEAR RECORD HIGH TEMPERATURES AND ELEVATED FIRE DANGER CONTINUE THIS WEEKEND ESPECIALLY SOUTH... A STRONG UPPER RIDGE WILL EXTENDED FROM NORTHERN GEORGIA TO THE CENTRAL PLAINS...WHILE MODELS BRING A VERY WEAK UPPER LEVEL DISTURBANCE ACROSS OUR REGION LATE SATURDAY AND SATURDAY NIGHT. FOR TONIGHT EXPECT A FEW LINGERING THUNDERSTORMS ACROSS OUR NORTH WITH DRY CONDITIONS SOUTH. THERE WILL BE A BETTER CHANCE OF THUNDERSTORMS SATURDAY AFTERNOON AND SATURDAY NIGHT WITH BEST CHANCES BEING NORTH OF I70 AS THE WEAK UPPER LEVEL DISTURBANCE MOVES BY. EVEN THOUGH MODELS SHOW A SLIGHT COOLING...WILL LEAN SOMEWHAT TOWARDS PERSISTENCE AS A STRONG UPPER RIDGE WILL BE JUST TO OUR SOUTH AND 850 MB TEMPERATURES WILL BE WELL ABOVE NORMAL. HIGHS THIS WEEKEND WILL RANGE FROM MID 90S OVER NORTHERN SECTIONS TO THE ALMOST 105 ACROSS OUR FAR SOUTH. WILL PROBABLY NEED SOME TYPE OF HEAT HEADLINES AT LEAST ACROSS OUR SOUTH THIS WEEKEND. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... ISSUED AT 210 PM EDT FRI JUN 29 2012 PREFER TO STICK CLOSER TO THE CONSISTANT ECWMF AND ITS RENDITION OF THE MORE EXPANSIVE UPPER DOME OF HIGH PRESSURE WHICH SHOULD KEEP IT HOT AND DRY. WOULDN'T RULE OUT ISOLATED CONVECTION HERE AND THERE FROM THE MODEL QPF PROGS...BUT FOR NOW WILL STICK WITH NO MENTION OF THUNDERSTORMS. && .AVIATION /DISCUSSION FOR THE 291800Z TAF ISSUANCE/... ISSUED AT 1130 AM EDT FRI JUN 29 2012 THE RAPID REFRESH REFLECTIVITY PROGS AND SPC CONTINUE TO SUGGEST ILLINOIS STORM COMPLEX WILL DEVELOP SOUTHEAST TOWARDS AN INSTABILITY AXIS AND MID 70 DEW POINTS POOLED IN THE VICNITY OF A STATIONARY FRONT FROM NEAR LAF TO IND BY 18Z. SO...WILL WAIT TIL THE LAST MINUTE AND DECIDE WHETHER OR NOT TO GO WITH VCTS OR TEMPO THUNDERSTORM GROUPS. THIS WILL LARGELY DEPEND ON ANY HINTS OF SOUTHWARD DEVELOPMENT. AT ANY RATE...WILL INCLUDE SOME FORM OF THUNDERSTORMS FOR AROUND 4 HOURS AT BOTH SITES. HUF AND BMG SHOULD BE TOO FAR SOUTH AND WEST TO INCLUDE ANY MENTION. OTHERWISE...VFR CONDITIONS SHOULD PREVAIL WITH SOME CHANCE OF OVERNIGHT FOG AT IND AND LAF WHICH WILL LARGELY DEPEND ON IF EITHER OR BOTH SITES RECEIVE ANY RAINFALL AND ALSO THE POSITION OF THE QUASI STATIONARY FRONT AND ITS HIGHER POOLED DEW POINTS. COULD ALSO SEE ADDITONAL THUNDERSTORMS TONIGHT AND TOMORROW IN THE VICINITY OF THE FRONT...HOWEVER CHANCES ARE TO LOW RIGHT NOW TO MENTION ANYTHING. WINDS WILL BE AROUND 10 KNOTS THIS AFTERNOON FROM THE WEST AND SOUTHWEST AT BMG AND HUF BEFORE BECOMING LIGHT TO CALM TONIGHT AND NEAR 10 KNOTS AGAIN LATE TOMORROW MORNING. WIND DIRECTIONS ARE MOPRE PROBABLE AT IND AND LAF WITH THE FRONT IN THE VICINITY AND WITH THE POSSIBILITY OF THUNDERSTORM GUSTS. && .FIRE WEATHER... ISSUED AT 350 AM EDT FRI JUN 29 2012 WILL CONTINUE MENTION OF ENHANCED FIRE DANGER. HUMIDITIES ACROSS OUR SOUTH MAY APPROACH 25 PERCENT...BUT WINDS WILL NOT BE HIGH ENOUGH TO REACH RED FLAG CRITERIA TODAY. && .CLIMATE...
