About hail reports in Rapid City
Rapid City has a history of significant hail events, driven by its unique topography near the Black Hills. A notable severe storm in July 2020 dropped baseball-sized hail across the metro area, causing extensive damage to vehicles and roofs. The peak hail season typically runs from June through August, when atmospheric instability is highest.
This Rapid City area research page connects reported NOAA/SPC hail activity with THOR’s interactive map. Use the map to investigate a place, ZIP code, county, address, or storm area alongside available hail swaths, NEXRAD radar, and Timeline replay.

Hail map questions
What is a hail swath map?
A hail swath is a radar-derived estimate of where a hail-producing storm cell traveled. THOR places swaths beside reported hail events, radar, and Timeline replay so you can study the full storm corridor.
Can I check hail history by address?
Yes. THOR searches by address, ZIP code, county, or place and creates Property Storm History reports that stay in My Reports for reopening, sharing, or browser PDF export.
Can roofing teams use THOR for canvassing?
Yes. THOR includes built-in canvassing with map pins, imported leads, statuses, notes, call and drive actions, follow-up dates, Storm Hits, Lead Storm Monitor, and exportable storm data.
How does THOR help prioritize storm damage work?
Market Priority compares the storm events already on the map with household, residential-density, population, and Residential Score context. Impact View, Heat Grid, and Timeline help the team sort the broader storm picture before field follow-up.
