A warm front was located across northern Indiana, helping to enhance effective shear (40 to 50 kts). Over 1000 J/KG of MLCAPE was in place ahead of 2 HP supercells that developed across portions of northern Illinois into northwestern Indiana. The first storm tracked from neat Joliet, IL and then turned east, moving into LaPorte and St Joseph counties before dissipating. Immediately behind this storm, another supercell developed in Will County, Indiana and moved east from southern LaPorte county into the Plymouth area before quickly dissipating. DCAPE over 1000 J/KG aided in damaging wind development, with at least 1 rotating wall cloud noted west of Plymouth. No tornadoes were observed.
