Nallen, WV Hail Storm – April 2026

Nallen, West Virginia recorded sub-inch hail on April 29, 2026, with a peak measurement of 0.72 inch during a brief late-afternoon thunderstorm. The storm has concluded.

What Happened

Around 3:43 PM EDT the National Weather Service issued a severe thunderstorm warning for the Nallen area citing the potential for up to 1.25-inch hail; the alert was issued as NWS warning only. Dual-polarization radar returns showed a compact hail echo moving northeast across the Nallen metro. Radar-detected hail echoes produced a narrow hail swath across town during late afternoon and then weakened as the cell moved away.

No ongoing warnings remained after the cell exited the area. Local observations and radar cross-sections indicate the event was short lived and confined to a limited corridor through the Nallen metro.

Damage Assessment

Hail associated with this event reached sub-inch diameters in Nallen. At this size, common field impacts are limited. Vegetation bruising and minor window or siding pitting are the most likely outcomes. Older asphalt shingles may show localized granule loss. Newer architectural shingles, metal roofing, and impact-rated glass are unlikely to sustain structural damage from sub-inch hail.

Vehicle panels and soft metals can show small dings where exposure was continuous. Expect any physical effects to be patchy and concentrated where the radar-detected swath passed over populated streets and properties in the Nallen metro.

What Contractors Should Know

Prioritize visual roof inspections in the areas crossed by the radar hail swath. Look for granule loss, shingle edge breakage, and isolated bruising on soft metals. Use attic checks for concealed leaks and perform exterior siding and gutter inspections. Document conditions with time-stamped, geotagged photos and note April 29, 2026 and the NWS warning time of 3:43 PM EDT on all records.

For estimating, segregate work by damage likelihood: quick-touch cosmetic repairs for isolated dents and pitting, and full-roof assessments only where granule loss or shingle fracture exceeds local replacement thresholds. Communicate findings to property owners with photo evidence and coordinate any permit or insurance steps promptly to avoid secondary water intrusion.
