NEXRAD logged 2 hail signatures up to 1"; the estimated-size surface reached 0" aloft. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
Evidence / storm surfaces
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.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
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
This was Kenney's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Kenney at 1" — the largest NEXRAD radar signature.
The Apr 27, 2026 convective day was bigger than Kenney: the same system put hail over 1,188 other tracked cities, 336 of them in Illinois. Nearest: Warrensburg (7 miles south, up to 2"); Maroa (9 miles southeast, up to 1.75"); Clinton (9 miles northeast, up to 1.25").
These maps are stills. In the app this date is one of 3 Kenney 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
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.
“EF1... max wind speed 88 mph... path length 6 miles... path width 400 yards. The tornado initially caused damage near the intersection of Rowell Rd and Bantam Rd... evi (ILX)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Rowell — beyond Kenney itself.
Damage-capable hail signal
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
Potential roof exposure
$360K
Potential roof exposure — 30 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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.
Names and phones for every home in the footprint: at most $6 on top of the $150 plan.
