Connecticut Hail Map — Last 30 SPC Reporting Days
While Connecticut experiences fewer severe hail events than the Plains, summer thunderstorms can still bring damaging hail to areas like Hartford and New Haven. Use our interactive Connecticut hail map to track recent storm damage and severe weather reports across the state. This page shows live NOAA/SPC hail reports for Connecticut in the last 30 days.
About hail reports in Connecticut
Connecticut averages only a few severe hail days per year, typically peaking between June and August when hot, humid air fuels strong thunderstorms. Notable events, such as the severe storms of May 2018, have produced golf-ball-sized hail that caused localized property and vehicle damage. Coastal sea breezes and frontal boundaries are the primary meteorological drivers for these severe storms.
This Connecticut statewide 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.

Data and method
THOR uses preliminary NOAA Storm Prediction Center reports as a starting point for local hail research. Reports can be revised or incomplete, so use the interactive map and available radar context to investigate the broader storm picture.

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.
Build the next storm workflow
THOR combines nationwide hail research with storm replay, mapping, reports, alerts, canvassing, lead follow-up, and exports in one workspace.
