How big was the hail on May 9, 2026?

The maximum estimated stone size anywhere in Oklahoma that day was 1.00 inches. Sizes vary street to street inside a single swath, so a city's figure is the largest radar estimated anywhere within about 5 miles of it.

Does this mean roofs were damaged?

Radar measures stone size, not damage. Whether a particular roof was damaged depends on stone size, wind direction, roof age and material — only an inspection settles it. These figures tell you where it is worth looking.

How do I see the actual swath on a map?
