Evidence / storm surfaces
How Rockford saw the hail — from two instruments
Jul 20, 2026 · Rockford, IA
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Max size
1.25"
Only the radar-estimated size surface resolved for Jul 20, 2026 — this storm produced no NEXRAD point detections over Rockford, so there is one map to show, not two.
The storm in context
Where Jul 20, 2026 sits in Rockford's hail record.
This was Rockford's 5th recorded hail day, arriving 12 days after the Jul 8, 2026 storm. By severity it ranks 4th of the 6 storms we have logged here. Radar put the day's largest stone over Rockford at 1.25" — radar-estimated size aloft.

Damage-capable hail signal
What 1.25" hail means for Rockford 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 Aug 8, 2026.
