Reports by year
Report counts are driven partly by how many people were around to report a storm, so recent years tend to look busier than the early 2010s. Treat the trend as a reporting trend, not purely a weather trend.

- How big is a 1.75" hailstone?
- Forecasters describe hail by everyday objects: 1" is a quarter, 1.75" a golf ball, 2.75" a baseball. The sizes in these reports are estimates made by the person reporting, not lab measurements.
- Where do I get the official record?
- All reports here come from the NOAA NCEI Storm Events Database, which you can search directly. For anything formal, use NOAA’s own records rather than this page.

About these numbers
Every row above is a report filed with the National Weather Service and archived in the NOAA NCEI Storm Events Database (FIPS 20149). Reports are eyewitness, trained-spotter and damage-survey observations, so they cluster near roads and towns and miss storms over empty country. Hail sizes are estimates. Damage figures are preliminary as filed and are never revised in this archive. Use this page for background, not for an insurance claim, a legal filing, or a roof assessment — for those, get the official record from NOAA directly.
