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 Northern Indiana wrote its last area forecast discussion before the first event at May 7, 2:30 PM EST, 2 hours 35 minutes earlier.

TIMING/STRENGTH/LOCATION OF THESE WAVES WILL HAVE LARGE IMPACTS ON FORECAST THROUGH WEEKEND. FOR TONIGHT...INITIAL AREA OF CONVECTION AHEAD OF WARM FRONT MOVING ACROSS SRN ILLINOIS. NOT CONFIDENT THIS AREA WILL MAKE IT INTO CWFA THIS EVENING AS IT OUT RUNS WARM FRONT AND INSTABILITY AND NEW CONVECTION DEVELOPS FARTHER WEST. WILL HAVE A CHANCE THIS EVENING TO ACCOUNT FOR THESE STORMS. THE NEW CONVECTION FARTHER WEST IS EXPECTED TO RIDE THE WARM FRONT AS IT LIFTS NORTH TONIGHT AND MOVE ACROSS OUR AREA OVERNIGHT. GOOD OMEGA PROGGED BY MODELS BEWEEN 06Z AND 15Z WITH INCREASING MID LEVEL INSTABILITY. BEING NORTH OF FRONT...LARGE HAIL AND HEAVY RAIN WOULD BE GREATEST THREAT. WILL CONTINUE WITH CATEGORICAL POPS BUT SOME CONCERN HOW FAR EAST THIS WILL MAKE IT TONIGHT. SHOULD LINGER IN THE EAST DURING THE MORNING. NO GOOD TRIGGER FOR FRI AFTERNOON BUT INSTABILITY INCREASES... ESPECIALLY SOUTHEAST. IF CONVECTION CAN BE TRIGGERED...SEVERE WILL BE A GOOD BET...WITH WIND AND HAIL THE THREATS.

SAT AFTERNOON AND SAT NIGHT AGAIN UNSTABLE IN WARM SECTOR AND AHEAD OF APCHG COLD FRONT. HIGH CHANCE POPS FOR NOW. COLDER AND DRIER AIR STARTS TO MOVE IN ON SUNDAY. SOME WRAP AROUND MOISTURE INDICATED BY MODELS SO KEPT A CHANCE OF SHRA SUNDAY. TEMPERATURES THIS TIME OF YEAR ARE HIGHLY DEPENDANT ON CLOUD COVER. WITH POTENTIAL FOR MCS AND DEBRIS CLOUDS EACH DAY...TEMPS COULD BE TEMPERED A BIT. WITH FAIR AMOUNT OF SUNSHINE...FRIDAY AND SATURDAY COULD EASILY BE INTO THE 80S. FOR NOW...WL CONFINE 80S TO SOUTHERN HALF OF CWA AND UPPER 70S NORTH AND EAST. ON MONDAY A LOW OVER THE NORTHERN GREAT LAKES WILL MOVE AWAY FROM OUR CWA AND THEN HIGH PRESSURE BUILDS INTO OUR CWA FOR TUESDAY AND WEDNESDAY. THEN ON THURSDAY A LOW WILL BE OVER TEXAS WITH A WARM FRONT THROUGH THE SOUTHEASTERN UNITED STATES. THE ECMWF, MRF, AND GEM BASICALLY AGREE WITH EACH OTHER ON THIS SCENARIO. HOWEVER, THE ECMWF MOVES THE LOW AWAY FROM MICHIGAN SLOWER DURING THE MIDDLE PART OF THE WEEK THAN THE OTHERS DO AND THE GFS HAS OUR CWA WET FOR THURSDAY AS IT BRINGS UP A WARM FRONT NORTHWARD THROUGH INDIANA. SO FOR THIS TIME FRAME, IT LOOKS LIKE THERE COULD STILL BE A CHANCE FOR RAIN SUNDAY NIGHT AS THAT LOW BEGINS TO MOVE AWAY AND THEN DRY THROUGH AT LEAST THURSDAY. MRF MOS HAS BEEN TRENDING COOLER WITH TEMPS AND SURROUNDING OFFICES COOLED THEIR TEMPS...SO I EDITED SOME OF THE MAX/MIN TEMPS TO REFLECT A COOLER WEEK AND TO AGREE WITH NEIGHBORING OFFICES. .IWX...
