Clarksville, MO Hail Storm – September 2026

Clarksville, MO experienced a late-afternoon hail-producing thunderstorm on September 18, 2026, with peak hail detected by dual-polarization radar. The storm is concluded.

What Happened

A single NWS warning area was issued for Clarksville at 5:12 PM CDT on September 18, 2026. The warning cited hail detected by dual-polarization NEXRAD. Radar-derived hail points concentrated along a narrow core crossing central Clarksville in the late afternoon. The system moved through the metro and then weakened; no further warnings were issued for the zone after the 5:12 PM alert.

NEXRAD hail detection identified the strongest returned signals along a corridor roughly aligned with the storm axis through town. No additional NWS warning areas are associated with this event for Clarksville. Ground reports tied to this warning are not present in the public warning record for the municipality.

Damage Assessment

Radar-detected hail reached a size that is larger than a US quarter coin (1.00 inch) and smaller than a golf ball (1.75 inches). Hail in that size range commonly produces denting to exposed vehicle panels, damage to vulnerable roof coverings such as single-layer asphalt shingles, and shattered glass on skylights or unprotected glazing when impacts are direct.

Local storm reports for Clarksville do not list spotter-verified roof failures or widespread structural collapses tied to this specific warning area. Observations are limited to the radar hail footprint and the NWS warning area issued at 5:12 PM CDT. Insurance and repair crews should prioritize inspection of parked vehicles, soft roofing, HVAC condensers on roofs and slabs, exterior metal flashing, and skylights along streets and parcels within the warning area.

What Contractors Should Know

Begin with a safety-first site assessment. Confirm power and gas are secure before close roof work. Prioritize properties inside the NWS warning area issued at 5:12 PM CDT. Document conditions with time-stamped photos oriented to the road and roof ridgelines. Note hail size references using the US coin scale when logging client reports.

For roofing inspections, look for localized shingle granule loss, split or fractured shingle tabs, and dents on metal flashings and gutters. On vehicles, check hood, roof, and trunk panels for round dents and cracked glass. Record GPS coordinates for each damaged asset and maintain a simple itemized list per address to streamline claims. Triage repairs by safety risk and water ingress potential.
