Evidence / storm surfaces
How Herscher saw the hail — from two instruments
Mar 10, 2026 · Herscher, IL
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar-estimated hail size Surface resolved
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Max size
2"
Only the radar-estimated size surface resolved for Mar 10, 2026 — this storm produced no NEXRAD point detections over Herscher, so there is one map to show, not two.
The storm in context
Where Mar 10, 2026 sits in Herscher's hail record.
This was Herscher's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Herscher at 2" — radar-estimated size aloft.
The Mar 10, 2026 convective day was bigger than Herscher: the same system put hail over 470 other tracked cities, 100 of them in Illinois. Nearest: Cabery (8 miles west, up to 1.5"); Reddick (13 miles northwest, up to 1.5"); Cullom (13 miles southwest, up to 1.25").
These maps are stills. In the app this date is one of 4 Herscher 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.

Severe hail signal
What 2" hail means for Herscher 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 Aug 3, 2026.
