NOAA's Probability of Severe Hail peaked at 90% over Cheyenne that day — high: around even odds of 1″ hail reaching the ground. 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.
