Greensboro Hail Map — Last 30 SPC Reporting Days

Greensboro and the surrounding Piedmont Triad frequently experience severe thunderstorms capable of producing damaging hail, particularly during the volatile spring months. Whether you are in Guilford College, Fisher Park, or downtown, our interactive map helps you track storm paths and potential property damage. This page shows live NOAA/SPC hail reports for Greensboro in the last 30 days.

About hail reports in Greensboro

Greensboro's location in the Carolina Piedmont makes it susceptible to severe supercells, with the peak hail season running from April through June. Notable events include the May 2014 severe weather outbreak that dropped golf-ball-sized hail across Guilford County, causing significant roof and vehicle damage. Local meteorological drivers, such as the clash of warm, moist Gulf air with approaching cold fronts, frequently trigger these intense localized storms.

This Greensboro 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

  1. Open the interactive map and review reported hail in the selected area.
  2. Compare the broader storm corridor with radar, hail swaths, and Timeline replay.
  3. Use Market Priority, Impact View, and map layers to focus the next area.
  4. 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.
