Oklahoma Hail Map — Last 30 SPC Reporting Days

Oklahoma is one of the most storm-active states in the US, with Oklahoma City, Tulsa, and the central plains recording frequent large hail events alongside tornado activity. The state sits at the intersection of Gulf moisture, dry continental air, and Rocky Mountain outflow — a recipe for destructive supercells. This page shows live NOAA/SPC hail reports for Oklahoma in the last 30 days.

About hail reports in Oklahoma

Oklahoma averages 50–60 significant hail days per year statewide. Oklahoma City has been struck by billion-dollar hail events multiple times, including the May 2010 storm that caused $1.1 billion in insured losses. The state's position in the heart of Tornado Alley means hail often accompanies tornado-producing supercells, making it one of the highest-priority states for roofing contractors.

This Oklahoma 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

  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.

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.
