Evidence / storm surfaces
How Flat Rock saw the hail — from two instruments
Feb 19, 2026 · Flat Rock, 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.
Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Max size
1"
Only the radar-estimated size surface resolved for Feb 19, 2026 — this storm produced no NEXRAD point detections over Flat Rock, so there is one map to show, not two.
The storm in context
Where Feb 19, 2026 sits in Flat Rock's hail record.
This was Flat Rock's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 3rd of the 9 storms we have logged here. Radar put the day's largest stone over Flat Rock at 1" — radar-estimated size aloft.
The Feb 19, 2026 convective day was bigger than Flat Rock: the same system put hail over 64 other tracked cities, 31 of them in Illinois. Nearest: Carlisle (9 miles northeast, up to 1.25"); Robinson (13 miles northwest, up to 0.75"); Oblong (16 miles west, up to 1.5").
These maps are stills. In the app this date is one of 9 Flat Rock 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.

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 Robinson, Hardinville, and New Hebron — beyond Flat Rock itself.
Damage-capable hail signal
What 1" hail means for Flat Rock roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
430 homes × $12,000 avg. claim
Potential roof exposure
$5.2M
Potential roof exposure — 430 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 430 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.

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.
