Evidence / storm surfaces
How Champaign saw the hail — from two instruments
Apr 27, 2026 · Champaign, IL
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

The storm in context
Where Apr 27, 2026 sits in Champaign's hail record.
This was Champaign's 2nd recorded hail day, arriving 32 days after the Mar 26, 2026 storm. By severity it ranks 3rd of the 3 storms we have logged here. Radar put the day's largest stone over Champaign at 1" — the largest NEXRAD radar signature.
The Apr 27, 2026 convective day was bigger than Champaign: the same system put hail over 1,188 other tracked cities, 336 of them in Illinois. Nearest: Urbana (8 miles east, up to 1"); White Heath (11 miles west, up to 1"); Tolono (11 miles south, up to 1").

Damage-capable hail signal
What 1" hail means for Champaign 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.
1,593 homes × $12,000 avg. claim
Potential roof exposure
$19M
Potential roof exposure — 1,593 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

- 8 jobs
- Illustrative work
- ~$120K
Close just 0.5% of the 1,593 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
April 2028
Claims from this storm can typically be filed until around April 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

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 12, 2026.
