Ardmore, OK Hail Storm – September 2025

Ardmore, OK was hit by a concluded hail storm on 2025-09-21 that produced a maximum confirmed hail size of 1.75 inches. The storm generated three NWS alert areas with dual-polarization radar support across the afternoon.

What Happened

The first alert came at 3:26 PM CDT with 1-inch hail confidence from dual-polarization radar. A second alert followed at 3:40 PM CDT with the same 1-inch hail estimate. The strongest alert arrived at 4:06 PM CDT, when radar confidence increased to 1.75-inch hail.

The alert sequence tracked a late-afternoon hail core moving through the Ardmore metro. All three alerts were issued on 2025-09-21 and are included in this multi-zone storm report. The storm has concluded.

Damage Assessment

Hail in the 1-inch to 1.75-inch range can produce a mixed damage pattern across roofs, soft metals, windows, and exterior trim. The lower end of that range often leaves impact marks on shingles, gutters, and siding. The upper end can add broken seals on windows, dented vents, and heavier losses on exposed roof slopes, skylights, and HVAC fins.

In Ardmore, the three-alert sequence points to more than one hail pulse across the event. Properties near the later 1.75-inch alert area should be checked first. Homes and commercial buildings with older asphalt shingles, thin gauge metal, or flat roof edges are more likely to show visible strike points and cosmetic denting. Vehicles parked outdoors during the late-afternoon core should also be inspected for windshield chips and body damage.

Crews should document roof planes separately. A single storm can leave one side of a structure with light impact marks and another with concentrated hail scarring. Soft metal, ridge caps, flashing, turbine vents, and downspouts are common field targets in this size range. On commercial sites, rooftop mechanical units and parapet metals often show the cleanest hail signatures.

What Contractors Should Know

This event supports a focused canvass in the Ardmore metro, with priority given to the later alert area around 4:06 PM CDT. Start with steep-slope roofs that face the storm path, then move to low-slope and accessory structures. Check for granular loss, bruising, cracked sealant, punctures in membranes, and impact marks on flashing and vents. Photograph each slope before and after close inspection. Keep roof, elevations, and exterior metals separated in the claim record.

Use the 1-inch alerts as a boundary check, not a finish line. The first two alerts may show lighter but still relevant damage, especially where the storm produced repeated hail cores. Contractors should compare field findings across the full path through Ardmore instead of assuming uniform loss. The best early indicators are roof accessories, gutter faces, window screens, and exposed vehicle lots near the alert corridor.
