Synoptic and mesoscale conditions for August 6th...A significant shortwave trough of low pressure combined with a mid level speed max of 60 knots and rapid prefrontal destabilization during the day of August 6th ahead of a strong cold front led to convective initiation across eastern Iowa by late morning.  Given favorable deep layer shear of 50 knots and extreme instability present from Northern Illinois into Northwest Ohio that afternoon... storms quickly organized into a bow echo squall line as they rapidly moved eastward at speeds of up to 50 knots.  As the bow echo matured... dramatic yet elevated rear inflow jet developed along the backside with isolated wind damage along and west of a Elkhart to Wabash line.  However, with time the rear inflow jet descended causing widespread wind damage across Whitley, Noble and Allen counties.
