Allen, KS Hail Storm – June 2025

Allen, KS saw a concluded hail storm on June 18, 2025, with a maximum confirmed hail size of 1 inch. The storm produced one NWS alert area during the afternoon and early evening.

What Happened

The storm was tracked in Allen, KS on Wednesday, June 18, 2025, with the key hail alert issued at 5:04 PM CDT. That alert called for 1-inch hail and carried dual-polarization radar confidence from NEXRAD. The event stayed single-zone and did not expand into multiple hail corridors.

The warning area remained focused on the Allen metro during the active period. Radar-derived hail detection showed a hail-producing core capable of reaching severe size, and the alert held to the 1-inch threshold. No later alert in this event increased the verified hail size above 1 inch.

The storm moved through in the late afternoon into early evening window. By conclusion, the event was no longer active and the verified hail total remained at 1 inch.

Damage Assessment

One-inch hail is enough to produce visible property impacts, especially on older roofs, soft metals, gutters, vents, siding, and exterior trim. Dented metal surfaces are common. Shingle bruising and edge damage also appear in reports after this hail size.

Vehicles parked in exposed areas can show pitting or chipped paint, depending on hail density and wind angle. Window screens, skylights, and AC fins are also common inspection points after a storm of this size.

For contractors, the event profile points to a narrow field inspection target. Start with roof slopes that faced the storm path during the warning area window. Check for collateral damage on ridge caps, pipe boots, flashing seams, and lightweight accessories around the roofline.

Look for mixed impacts. A single 1-inch hail storm can leave one side of a structure with clear marks while nearby surfaces show only minor scuffing. Document roof condition, soft-metal hits, and exterior accessory damage separately. That helps keep field notes tied to the actual hail exposure rather than broad neighborhood assumptions.

What Contractors Should Know

This was a single-zone hail event with a verified 1-inch peak. The report supports a targeted canvass rather than a wide-area assumption of uniform damage. Properties closest to the strongest radar-derived core deserve first-pass inspection, followed by the immediate surroundings inside the warning area.

Focus on evidence that matches 1-inch hail. Use straight-line visual checks on roof planes, gutters, downspouts, fascia, window screens, and vehicle surfaces. On roofs, pay attention to bruising, fractured mat exposure, granule displacement, and soft-metal strikes. On metal components, look for shallow but repeated dimples rather than isolated impact marks.

Access timing matters. Because the alert was issued at 5:04 PM CDT, the most useful field notes will come from inspections that separate storm-time impacts from pre-existing wear. Photograph each side of the structure. Record exposure on the windward and storm-facing elevations. Keep notes on tree cover, roofing age, and whether the property sat near the center of the warning area.
