How Sugar Grove saw the hail — from two instruments

Aug 11, 2026 · Sugar Grove, IL

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 map of the storm over Sugar Grove, IL on Aug 11, 2026 — 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.

Max size 0.75"

Only the radar-estimated size surface resolved for Aug 11, 2026 — this storm produced no NEXRAD point detections over Sugar Grove, so there is one map to show, not two.

Near the severe threshold

What 0.75" hail means for Sugar Grove roofs.

A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm 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 12, 2026.
