Hail in Sullivan · Jun 17, 2026
The estimated-size surface reached 3" aloft; NEXRAD logged no point detections over Sullivan that day. At 3" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Sullivan 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 Jun 17, 2026 — this storm produced no NEXRAD point detections over Sullivan, so there is one map to show, not two.
The storm in context
Where Jun 17, 2026 sits in Sullivan's hail record.
This was Sullivan's 5th recorded hail day, arriving 44 days after the May 4, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Sullivan at 3" — radar-estimated size aloft.
The Jun 17, 2026 convective day was bigger than Sullivan: the same system put hail over 294 other tracked cities, 134 of them in Illinois. Nearest: Lovington (7 miles north, up to 2.75"); Dalton City (11 miles northwest, up to 2"); Hammond (14 miles north, up to 2.25").

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 Sullivan 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.
Severe hail signal
What 3" hail means for Sullivan 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$55M
Potential roof exposure — 4,588 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 23 jobs
- Illustrative work
- ~$345K
Close just 0.5% of the 4,588 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
June 2028
Claims from this storm can typically be filed until around June 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 $963 on top of the $150 plan.
