How Seaton saw the hail — from two instruments

Jul 2, 2026 · Seaton, IL

We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.

NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Max size 0" Detections 0

Only the NEXRAD radar-signature surface resolved for Jul 2, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.

The storm in context

Where Jul 2, 2026 sits in Seaton's hail record.

This was Seaton's 5th recorded hail day, arriving 21 days after the Jun 11, 2026 storm. By severity it ranks 6th of the 7 storms we have logged here. Radar put the day's largest stone over Seaton at 0" — radar-estimated size aloft.

The Jul 2, 2026 convective day was bigger than Seaton: the same system put hail over 1,147 other tracked cities, 68 of them in Illinois. Nearest: North Henderson (16 miles east, up to 1"); New Windsor (17 miles northeast, up to 1"); Rio (21 miles east, up to 1").

These maps are stills. In the app this date is one of 7 Seaton 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.

For this storm over Seaton, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.

Below the severe threshold

What 0" hail means for Seaton roofs.

Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

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 13, 2026.
