Chance, hatched
The Storm Prediction Center’s own outlook: the chance of severe hail within 25 miles of a point. It is not a size, and it is not what fell.
Two different sets of cars, and they are never added together: the Census count is every vehicle kept by the households under this area; the lot count is inventory at sites mapped in OpenStreetMap. They overlap.
The forecast is the NOAA Storm Prediction Center’s (public domain, no endorsement implied). Cars on lots are mapped sites, people are U.S. Census estimates, and the towns are named and sized from GeoNames. U.S. Census Bureau · © OpenStreetMap contributors (ODbL) · © GeoNames (CC BY 4.0).
