Montana Hail Map & Hail Report History

Montana's high plains see frequent hail from late spring through summer, with the Billings and Great Falls corridors among the most active.

Every hail report below comes from official National Weather Service storm reports for Montana, covering the last 365 days. Times are Central. Sizes are the measured or estimated stone diameter in inches.

This is the Montana view. The national storm map adds live radar showing hail falling right now, real NWS warned storm paths, radar-measured hail footprints, and every state at once. Filters for date, state, and hail size can be set on the national hail map page.

How to read Montana hail sizes

  • 1" (quarter) — the NWS severe threshold. Enough to dent soft metal and bruise shingles.
  • 1.75" (golf ball) — widespread vehicle dents and the size that usually opens PDR work.
  • 2.5"+ (tennis ball and up) — roof fractures, broken glass and full-scale catastrophe deployments.
