Hail in Roland · Jul 20, 2026
The estimated-size surface reached 2" aloft; NEXRAD logged no point detections over Roland that day. At 2" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Roland saw the hail — from two instruments
Jul 20, 2026 · Roland, 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.
Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

Only the radar-estimated size surface resolved for Jul 20, 2026 — this storm produced no NEXRAD point detections over Roland, so there is one map to show, not two.
The storm in context
Where Jul 20, 2026 sits in Roland's hail record.
This was Roland's 5th recorded hail day, arriving 18 days after the Jul 2, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Roland at 2" — radar-estimated size aloft.
The Jul 20, 2026 convective day was bigger than Roland: the same system put hail over 553 other tracked cities, 178 of them in Iowa. Nearest: Radcliffe (7 miles north, up to 1.75"); Ellsworth (9 miles northwest, up to 1.75"); Story City (10 miles west, up to 2").
These maps are stills. In the app this date is one of 5 Roland storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.

Severe hail signal
What 2" hail means for Roland 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 Aug 3, 2026.
