NOAA's Probability of Severe Hail peaked at 30% over Kirkwood that day — low to moderate: the radar signature was there, ground impact less certain. 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 MRMS radar (MESH), which runs about ±0.25″ against ground truth. It is canvass-targeting quality, not claim evidence.
