How Brimfield saw the hail — from two instruments

Apr 17, 2026 · Brimfield, 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.

The storm in context

Where Apr 17, 2026 sits in Brimfield's hail record.

This was Brimfield's 3rd recorded hail day, arriving 15 days after the Apr 2, 2026 storm. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Brimfield at 2.5" — the largest NEXRAD radar signature.

The Apr 17, 2026 convective day was bigger than Brimfield: the same system put hail over 1,016 other tracked cities, 101 of them in Illinois. Nearest: Elmwood (5 miles west, up to 1"); Williamsfield (13 miles northwest, up to 3"); Farmington (13 miles southwest, up to 2.75").

These maps are stills. In the app this date is one of 6 Brimfield 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.

How the storm moved

Timing and place names from NOAA ground reports

Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.

Reports came from Laura — beyond Brimfield itself.

Severe hail signal

What 2.5" hail means for Brimfield roofs.

Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 Sep 16, 2026.
