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.

Common questions about hail in Grant County
- How often does it hail in Grant County?
- Hail was reported on 56 separate days between 2010 and 2025, about 3.5 days a year, with June the busiest month for storm reports. 94 reports were quarter size (1") or larger.
- Does a report here mean hail hit my street?
- Not necessarily. Each report is one observation tied to a nearby landmark, and a county can be large. Storms also go unreported where few people live. Use the date check above to see what was reported nearby, and treat it as a starting point.
- 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 20067). 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.
