Hail in Roland Jul 20, 2026
Hit 14 days agoThe radar-estimated size surface caught this storm, reaching 2" aloft. NEXRAD logged no point detections over Roland this day. At 2" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Roland saw the hail — from two instruments
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
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.
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"); Story City (8 miles west, up to 2"); Nevada (11 miles south, up to 2").
These maps are stills from Roland's Jul 20, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
What people on the ground reported

What 2" hail means for Roland roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
