About hail reports in Concord
While New Hampshire experiences fewer severe hail events than the Midwest, Concord occasionally sees significant summer thunderstorms that produce damaging hail. Notable storms in the region have brought 1-inch to 1.5-inch hail, particularly during the peak severe weather season from June through August, driven by cold fronts sweeping across the New England terrain.
This Concord 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.
From hail research to field work
- Open the interactive map and review reported hail in the selected area.
- Compare the broader storm corridor with radar, hail swaths, and Timeline replay.
- Use Market Priority, Impact View, and map layers to focus the next area.
- Save the investigation as a property report, lead workflow, alert, or export.

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.
