The episode as NWS IND wrote it up.
After a dry first week to the month, strong to severe thunderstorms impacted central Indiana periodically throughout the remainder of June as the Ohio Valley remained in a generally unsettled weather pattern. A humid air mass remained across central and|southern Indiana from the 11th through the 23rd. A series of storms from the 12th through the 18th dropped 4 to more than 8 inches of rainfall in northern Indiana. A west-east line of storms developed across central Illinois and expanded eastward into central Indiana on the afternoon of June 18th, producing a few damaging wind reports.
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 Indianapolis, IN wrote its last area forecast discussion before the first event at Jun 18, 1:14 PM EST, 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 214 PM EDT THU JUN 18 2015 .UPDATE... THE LONG TERM SECTION HAS BEEN UPDATED BELOW. && .SYNOPSIS... ISSUED AT 354 AM EDT THU JUN 18 2015 UNSETTLED WEATHER CONTINUES ACROSS CENTRAL INDIANA AS AN UPPER LEVEL RIDGE OVER THE SOUTHEAST...A FRONTAL SYSTEM LINGERING ACROSS THE MIDWEST...AND THE APPROACH OF THE REMNANTS OF TROPICAL CYCLONE BILL COMBINE TO MAKE FOR THUNDERSTORM CHANCES EACH DAY AND NIGHT THROUGH EARLY NEXT WEEK. THE MOST CRITICAL OF THESE TIMES WILL BE FRIDAY INTO SATURDAY AS THE BILL REMNANTS MOVE UP THE OHIO VALLEY...POTENTIALLY BRINGING VERY HEAVY RAINFALL AND FLOODING TO THE AREA. && .NEAR TERM /REST OF TODAY/... ISSUED AT 1033 AM EDT THU JUN 18 2015 1400Z UPDATE...MANY CHANGES TO THE FORECAST FOR THE FIRST HALF OF THE DAY. MAINLY TO REMOVE POPS UNTIL LATER THIS AFTERNOON AND ALLOW FOR CLEAR SKIES ACROSS THE SOUTH AS IS CURRENTLY BEING DEPICTED...AND THEN THIS WILL BEGIN TO FILL BACK IN AS THE PESKY BOUNDARY BEGINS TO DROP BACK SOUTHWARD AGAIN AND THIS TRIGGERS RENEWED DEVELOPMENT FOR SHOWERS AND THUNDERSTORMS MAINLY LATER THIS AFTERNOON AND EVENING. DEBATED ON WHETHER TO LOWER HIGH TEMPERATURES TODAY BASED ON RECENT COOLER TRENDS...AND THE FACT CLOUDS AND RAIN WILL BE MOVING IN A FEW HOURS AS WELL. HOWEVER ULTIMATELY DECIDED THAT AS THE LOW LEVEL SOUTHWEST FLOW PICKS UP THIS AFTERNOON AND BEGINS PUMPING EVEN WARMER AIR INTO THE FORECAST AREA...THIS IS USUALLY WHAT ENDS UP BUSTING FOR THE FORECASTER WHO CHOOSES TO DROP HIGH TEMPERATURES. MADE SOME OTHER MINOR MODIFICATIONS TO THE FORECAST BASED ON LATEST TRENDS AND NEAR TERM GUIDANCE. UPDATED FORECAST ALREADY WENT OUT AROUND 945/1000 AM TIMEFRAME. AND THE PREVIOUS DISCUSSION FOLLOWS... CONDITIONS ARE QUIET ACROSS CENTRAL INDIANA THIS MORNING WITH A LACK OF UPPER LEVEL SUPPORT AT THE MOMENT FOR PRECIPITATION...BUT AN APPROACHING SHORTWAVE AHEAD OF THE BILL REMNANTS...AS WELL AS POTENTIAL THUNDERSTORM ACTIVITY ALONG THE LINGERING FRONTAL SYSTEM IN THE HEAT OF THE AFTERNOON...WILL NECESSITATE LIKELY POPS ACROSS THE AREA THIS AFTERNOON. CANNOT ARGUE WITH THE SLIGHT RISK FOR TODAY...BUT HYDRO CONCERNS CONTINUE TO BE THE MORE PRESSING ISSUE. FLASH FLOOD GUIDANCE VALUES REMAIN RELATIVELY HIGH ACROSS MUCH OF THE AREA SAVE FOR THE EXTREME NORTH AND NORTHEAST...AND THUS EXPECT ANY FLASH FLOOD THREAT TO BE VERY LOCALIZED TODAY. ON TEMPS...CONSENSUS NUMBERS APPEARED SLIGHTLY TOO WARM GIVEN EXPECTED CLOUD COVER AND PRECIP TODAY. && .SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/... ISSUED AT 354 AM EDT THU JUN 18 2015 FOCUS OF THE SHORT TERM IS ON THE IMPACTS OF THE BILL REMNANTS WHICH APPEAR LIKELY TO MOVE UP THE MID MISSISSIPPI AND OHIO VALLEYS FRIDAY INTO SATURDAY. MODELS HAVE CONTINUED TO TREND A BIT FURTHER SOUTH AND WILL FOCUS HIGHEST POPS ACROSS THE SOUTHERN FORECAST AREA DURING THIS TIME PERIOD...AS WELL AS INSERTING A HEAVY RAIN MENTION. A BIT EARLY FOR A FLOOD WATCH ESPECIALLY GIVEN THAT THE AREA IN QUESTION HAS BEEN AMONG THE DRIEST AREAS IN THE STATE IN RECENT DAYS...BUT WILL ISSUE AN ESF TO HIGHLIGHT THE THREAT AS WELL AS CONTINUING TO MENTION IN OTHER VENUES. ON TEMPS...CONSENSUS NUMBERS APPEARED REASONABLE WITH MINOR TWEAKS. PRECIP WILL HAVE EXTENSIVE IMPACTS ON MAX TEMPS ESPECIALLY OVER THE NEXT COUPLE OF DAYS. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... ISSUED AT 214 PM EDT THU JUN 18 2015 A LARGE AREA OF UPPER LEVEL HIGH PRESSURE LOCATED OVER THE DESERT SOUTHWEST WILL PUSH EASTWARD ACROSS THE SOUTHERN UNITED STATES DURING THE PERIOD. THIS WILL RESULT IN FLOW VEERING FROM MORE QUASI-ZONAL TO MORE NORTHWESTERLY AS THE SUBSEQUENT RIDGE PUSHES INTO THE AREA TOWARDS THE END OF THE PERIOD. SEVERAL SHORT WAVES WILL MOVE ACROSS CENTRAL INDIANA IN THIS FLOW...HELPING TO AID IN THE UNSETTLED WEATHER PATTERN. AT THE SURFACE...A FRONT OVER THE OHIO RIVER VALLEY SUNDAY NIGHT WILL PUSH OFF TO THE EAST AS A SECONDARY FRONT MOVES IN FROM THE NORTHWEST LATE MONDAY INTO TUESDAY. A LOW PRESSURE SYSTEM WILL THEN MOVE IN FROM THE UPPER MIDWEST. HOWEVER THE MODELS ARE NOT IN AGREEMENT AS TO THE TRACK OF THE LOW AT THIS TIME...WITH THE EURO KEEPING CENTRAL INDIANA DRIER STARTING WEDNESDAY AFTERNOON THROUGH THURSDAY. REGIONAL INITIALIZATION IS TRENDING MORE TOWARDS THE GFS...WHICH CALLS FOR POPS THROUGH THE PERIOD. GFS LOOKS TO BE THE BETTER SOLUTION AT THIS TIME...SO WILL NOT BE MAKING ANY CHANGES TO THE INITIALIZATION. SUPERBLEND TEMPERATURES LOOK GOOD THROUGH THE PERIOD WITH THE AFTERNOON HIGHS IN THE MID TO UPPER 80S...WITH THE WARMEST TEMPERATURES COMING ON THURSDAY TO END THE PERIOD. AT THIS TIME...HEAT INDEX VALUES WILL HIT 100 DEGREES ACROSS MUCH OF SOUTH CENTRAL INDIANA. OVERNIGHT LOWS WILL REMAIN STEADY IN THE UPPER 60S TO LOW 70S. && .AVIATION /DISCUSSION FOR 181800Z TAF ISSUANCE/... ISSUED AT 1256 PM EDT THU JUN 18 2015 OUTSIDE OF CONVECTION...VFR CONDITIONS EXPECTED FOR 1ST HALF OF TAF PERIOD...THEN MVFR. LOW CLOUDS HAVE SCATTERED ALLOWING SUNSHINE...AND THIS HEATING IS CREATING SCATTERED CONVECTION ACROSS ILLINOIS. CURRENT TRACK OF THIS CONVECTION IS WEST OF KIND AND NEAR OR WEST OF KHUF/KLAF. HOWEVER IN INCREASING INSTABILITY EXPECT ADDITIONAL SCATTERED CONVECTION TO FORM THIS AFTERNOON. SINCE BULK OF CONVECTION THAT IS HEADED TOWARD SITES IS NOT ORGANIZED AM HESITANT TO GO ANYTHING HIGHER THAN VCTS THIS AFTERNOON. WILL ADD TEMPO IF NECESSARY WHEN TRENDS BECOME CLEARER. CONVECTION WILL WEAKEN THIS EVENING BUT UPPER LEVEL ENERGY WILL CREATE MORE SHOWERS LATE EVENING INTO THE OVERNIGHT. THESE WILL LIKELY LINGER INTO FRIDAY MORNING. WENT PREDOMINANT SHOWERS...WITH MVFR CONDITIONS. THERE IS A CHANCE FOR IFR AROUND 12Z BUT CONFIDENCE NOT HIGH ENOUGH TO ADD AT THIS TIME. && .IND WATCHES/WARNINGS/ADVISORIES...
