Evidence / storm surfaces
How Trivoli saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for Sep 15, 2026 — this storm produced no NEXRAD point detections over Trivoli, so there is one map to show, not two.
The storm in context
Where Sep 15, 2026 sits in Trivoli's hail record.
This was Trivoli's 4th recorded hail day, arriving 25 days after the Aug 21, 2026 storm. By severity it ranks 4th of the 4 storms we have logged here. Radar put the day's largest stone over Trivoli at 0.5" — radar-estimated size aloft.
The Sep 15, 2026 convective day was bigger than Trivoli: the same system put hail over 169 other tracked cities, 31 of them in Illinois. Nearest: Brimfield (9 miles northeast, up to 1.75"); Yates City (10 miles northwest, up to 1"); Edwards (13 miles northeast, up to 1.25").
These maps are stills. In the app this date is one of 4 Trivoli 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
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.
Nobody on the ground filed a report over Trivoli for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Below the severe threshold
What 0.5" hail means for Trivoli 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$1.7M
Potential roof exposure — 140 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 140 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.
Claim window
September 2028
Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $29 on top of the $150 plan.
