Severe-hail probability peaked at 50% over Downers Grove that day — moderate: severe hail likely reached the ground somewhere nearby. It is a separate model from the size estimate above: one asks how big the stones were in the storm, the other asks whether they made it down.
Sizes come from NOAA radar, which runs about ±0.25″ against ground truth. It is canvass-targeting quality, not claim evidence.
