Doniphan, MO Hail Storm – September 2026

Doniphan, MO experienced hail-producing storms on September 10–11, 2026 with peak hail of 1.6 inches. The event was brief and produced a localized hail track through the Doniphan area.

What Happened

Storm initiation occurred in late evening on September 10, with the NWS issuing the first warning at 8:02 PM CDT. That warning covered the initial convective cell and was marked as NWS warning only. The system redeveloped and prompted a second NWS warning at 12:24 AM CDT on September 11, also recorded as NWS warning only. Radar analysis and subsequent reports show hail reached a maximum size of 1.6 inches during the late-evening to early-overnight window. The event concluded shortly after the second warning period.

The hail footprint was narrow and concentrated. Radar-detected hail points align with a short track through Doniphan and immediate outskirts. No extended swath was observed on broader scans. Ground verification corresponded to the radar signature used to record the 1.6-inch peak.

Damage Assessment

A 1.6-inch hailstone falls between a quarter (1.00 inch) and a golf ball (1.75 inches) on the NWS object scale. In Doniphan, this size commonly produces: denting to vehicle body panels and aluminum trim; loss of granules and bruising on asphalt shingles, primarily on windward exposures; cracked or broken skylights and sunroofs in older installations; and localized damage to vinyl siding corners and exposed outdoor equipment.

Reports tied to this event indicate the most frequent effects were vehicle dents and accelerated shingle wear. No widespread structural failures were reported in the Doniphan area. Fragile exterior materials and unreinforced glass remain the highest immediate risk across affected properties.

What Contractors Should Know

Inspect roofs first thing after daylight. Focus on shingle granule loss, bruising, and displaced tabs on windward slopes. Photograph damage with scale references and capture timestamps. On vehicles, document panel dents and broken glass before covers or tow-away. Check HVAC condensers and exposed piping for impact damage. Prioritize temporary protection for openings that expose interior spaces.

When preparing estimates and claims packets, include the NWS warning times of 8:02 PM CDT on Sept 10 and 12:24 AM CDT on Sept 11. Note the reported 1.6-inch maximum hail size and the local radar-detected track through Doniphan. Provide before-and-after imagery, roof measurements, and a concise list of immediate mitigation actions. Coordinate tarping or temporary repairs with property owners and adjusters to avoid secondary water damage.
