A very warm and unstable air-mass advected into the region.  Outflow from morning convection and some mid/high clouds helped to keep the area capped for most of the day.  Convection began firing over Iowa around 18 UTC and quickly formed into a forward propagating Mesoscale Convective System (MCS) that followed the instability gradient into northern Indiana during the evening hours.  The storms were most intense as they entered Laporte County, and slowly weakened with time.  Despite the weakening trend, damaging winds were reported well into the evening.
