Evidence / storm surfaces
How Hull saw the hail — from two instruments
Jun 27, 2026 · Hull, IA
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

The storm in context
Where Jun 27, 2026 sits in Hull's hail record.
This was Hull's 5th recorded hail day, arriving 26 days after the Jun 1, 2026 storm. By severity it ranks 1st of the 10 storms we have logged here. Radar put the day's largest stone over Hull at 4" — the largest NEXRAD radar signature.

Severe hail signal
What 4" hail means for Hull roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 2, 2026.
