Wider weather episode

A persistently humid and unseasonably warm air mass provided ample instability late on the 16th. Meanwhile, mid-level forcing streamed into central Indiana from west to east, around the southeastern periphery of a strong mid-latitude cyclone positioned over the Upper Midwest. These ingredients combined to produce rotating storms with damaging winds and tornadoes across southern central Indiana through the late day.
