The episode as NWS IWX wrote it up.
A weakening complex of thunderstorms moved into portions of northern Indiana and southern Lower Michigan. The thunderstorms were not able to mix down the stronger winds aloft as they moved through. However, a wake low behind the complex, in the somewhat cooler air, was able to mix down winds generally in the 30 to 40 mph range. While isolated reports of tree limbs down were received, damage across portions of Branch county was a bit more widespread.

NWS Northern Indiana wrote its last area forecast discussion before the first event at Jun 15, 12:44 PM EST, 11 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 144 PM EDT WED JUN 15 2011 .UPDATE... INITIAL SURGE OF RAIN AND EMBEDDED STORMS HAS WEAKENED CONSIDERABLY WITH SOME LINGERING RAIN IN EASTERN SECTIONS. AREA OF CLEARING TO THE WEST ASSOCIATED WITH SHEARING MCV MOVING ACROSS ILLINOIS HAS LIMITED INSTABILITY. OUTFLOW BOUNDARY SHOT RAPIDLY NW ACROSS THIS AREA AND ALLOWED FOR DEVELOPMENT OF SCT SHOWERS AND STORMS. THESE ARE JUST AWAY FROM THE MAIN INSTABILITY AND LIKELY SLIGHTLY ELEVATED CONSIDERING THEY ARE MOVING OVER SAME AREAS THAT HAD RAIN THIS MORNING. HAVE OPTED FOR SCT WORDING INTO THIS AFTERNOON TO COVER ONE OR MORE AREAS OF SCATTERED SHOWERS AND STORMS. TRENDS MAY CONTINUE INTO THIS EVENING. HAVE ALSO LOWERED TEMPS IN SOME AREAS WITH CLOUD COVER HOLDING BACK ANY APPRECIABLE HEATING ACROSS MUCH OF THE AREA. && .AVIATION...

HOWEVER...EXPECT INTENSITY AND POSSIBLY COVERAGE OF CONVECTION TO WANE WITH ITS EWD PROGRESSION.
