Evidence / storm surfaces
How Parkersburg saw the hail — from two instruments
Sep 4, 2026 · Parkersburg, IA
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar-estimated hail size Surface resolved
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Max size
1.25"
Only the radar-estimated size surface resolved for Sep 4, 2026 — this storm produced no NEXRAD point detections over Parkersburg, so there is one map to show, not two.

Damage-capable hail signal
What 1.25" hail means for Parkersburg roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 5, 2026.
