Evidence / storm surfaces
How Saint Elmo saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for Jun 17, 2026 — this storm produced no NEXRAD point detections over Saint Elmo, so there is one map to show, not two.
The storm in context
Where Jun 17, 2026 sits in Saint Elmo's hail record.
This was Saint Elmo's 4th recorded hail day, arriving 45 days after the May 3, 2026 storm. By severity it ranks 2nd of the 6 storms we have logged here. Radar put the day's largest stone over Saint Elmo at 1.5" — radar-estimated size aloft.
The Jun 17, 2026 convective day was bigger than Saint Elmo: the same system put hail over 294 other tracked cities, 134 of them in Illinois. Nearest: Brownstown (5 miles west, up to 1"); Altamont (9 miles northeast, up to 1.5"); Vandalia (9 miles southwest, up to 0.5").

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.
For this storm over Saint Elmo, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
High damage potential
What 1.5" hail means for Saint Elmo roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$13M
Potential roof exposure — 1,103 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 6 jobs
- Illustrative work
- ~$90K
Close just 0.5% of the 1,103 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 $232 on top of the $150 plan.
