Evidence / storm surfaces
How Oswego saw the hail — from two instruments
Jun 10, 2026 · Oswego, 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 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.
Max size
0.75"
Only the radar-estimated size surface resolved for Jun 10, 2026 — this storm produced no NEXRAD point detections over Oswego, so there is one map to show, not two.
The storm in context
Where Jun 10, 2026 sits in Oswego's hail record.
This was Oswego's 3rd recorded hail day, arriving 72 days after the Mar 30, 2026 storm. By severity it ranks 3rd of the 6 storms we have logged here. Radar put the day's largest stone over Oswego at 0.75" — radar-estimated size aloft.
The Jun 10, 2026 convective day was bigger than Oswego: the same system put hail over 777 other tracked cities, 81 of them in Illinois. Nearest: Yorkville (5 miles west, up to 0.75"); Naperville (6 miles northeast, up to 0.75"); Aurora (7 miles north, up to 0.75").

Near the severe threshold
What 0.75" hail means for Oswego 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 3, 2026.
