Mount Vernon, OH Hail Storm – June 2026

Mount Vernon, OH recorded 2.23-inch hail on June 6, 2026, as a multi-zone hail event that produced 71 NWS alerts and several radar-detected hail cores. The storm concluded the same day.

What Happened

The event began in mid-morning and produced a long sequence of NWS alerts from 11:48 AM EDT through 9:34 PM EDT. Sixty of the alerts were described as NWS warning only detections with hail size estimates clustered at 0.75–1.00 inch. Multiple dual-polarization radar detections occurred in the late afternoon and early evening, including a 1.62-inch radar-detected core near 4:55 PM EDT, a 1.09-inch core at 5:45 PM EDT, a 1.03-inch core at 6:41 PM EDT, and a 1.5-inch core at 7:01 PM EDT. The sequence shows repeated warning polygons moving through the metro mount-vernon-oh notification zone, with radar-indicated hail cores embedded within that broader warning area.

Alerts were issued in concentrated bursts during late afternoon and early evening. The majority of official NWS messages carried hail size guidance without independent radar confirmation. Where dual-polarization radar indicated larger cores, those detections matched the periods of highest alert density between about 4:50 PM EDT and 7:35 PM EDT.

Damage Assessment

Hail impacts across Mount Vernon were variable. Frequent NWS warning guidance and radar cores indicate a common range near three-quarters to one inch during much of the event, increasing to larger stones during the late-afternoon to early-evening pulse when radar-detected cores reached beyond an inch. For exposed vehicles and outdoor equipment, 0.75–1.0 inch hail commonly causes paint chips and dents in softer body panels. Hail above 1.25 inches markedly raises the probability of more significant metal deformation, shingle granule loss on asphalt roofs, and damaged skylights or loose glazing. Roof-mounted equipment and parked vehicles exposed during the 4:50 PM–7:35 PM EDT window carried the highest observed risk.

Field reports specific to neighborhoods within the Mount Vernon metro are limited in this aggregate record. Where larger radar-detected cores passed directly over built areas, expect a higher incidence of cosmetic and functional damage to siding, gutters, and vehicle bodywork, and local inspections should prioritize those corridors.

What Contractors Should Know

Inspect roofs first in areas that were under radar-indicated cores between late afternoon and early evening. Photograph hail size next to a ruler or coin and geotag images where possible. Prioritize visible shingle granule loss, split shingle tabs, dented metal flashings, damaged skylights, and gutters. For vehicles, document dents and paint damage with context shots showing location and timestamped images.

Coordinate temporary protections before permanent repairs where interior exposures are present. Tarping, board-up of broken glazing, and rapid roof covers reduce secondary water damage. Maintain ladder and fall-protection protocols while working on roofs. For claims and repair scopes, separate small cosmetic repairs from structural penetrations; note radar-detected hail cores and the NWS warning timeline when filing documentation.
