How Maquon saw the hail — from two instruments

Jun 11, 2026 · Maquon, 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 Maquon, IL on Jun 11, 2026 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.

Max size 0.75"

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

The storm in context

Where Jun 11, 2026 sits in Maquon's hail record.

This was Maquon's 2nd recorded hail day, arriving 72 days after the Mar 31, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Maquon at 0.75" — radar-estimated size aloft.

The Jun 11, 2026 convective day was bigger than Maquon: the same system put hail over 648 other tracked cities, 157 of them in Illinois. Nearest: Gilson (3 miles north, up to 1"); Yates City (8 miles east, up to 0.5"); Farmington (13 miles southeast, up to 0.75").

These maps are stills. In the app this date is one of 3 Maquon 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.

Ground reports

What people on the ground reported

No reports filed with the NWS

These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.

The National Weather Service logged no spotter reports for this storm over Maquon. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.

Near the severe threshold

What 0.75" hail means for Maquon 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 20, 2026.
