Environment
An area of thunderstorms across Wisconsin the early morning hours of May 16 moved south during the morning toward Indiana. Although the storms were initially though to weaken and dissipate, they were able to tap into instability to the west. The storms strengthened and increased in coverage, bringing the severe weather to the area during the afternoon and early evening.

| Figure 1: Storm Prediction Center Mesoscale Discussion Graphic highlighting the potential for the storms to continue into the afternoon | Figure 2: Deep Moisture Convergence at 3:00 PM | Figure 3: Warm Advection at 850 mb at 3:00 PM EDT. Warm advection helped sustain the thunderstorms. |
The storms moved along a gradient in instability, aided by a mid-level jet. Stronger shear and instability near the Illinois border lead to the development of a supercell thunderstorm, which produced 2.5" diameter hail.
