The estimated-size surface reached 1" aloft; NEXRAD logged no point detections over Batavia that day. 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.

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.
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.
Only the radar-estimated size surface resolved for Jun 17, 2026 — this storm produced no NEXRAD point detections over Batavia, so there is one map to show, not two.
The storm in context
This was Batavia's 7th recorded hail day, arriving 33 days after the May 15, 2026 storm. By severity it ranks 3rd of the 10 storms we have logged here. Radar put the day's largest stone over Batavia at 1" — radar-estimated size aloft.
The Jun 17, 2026 convective day was bigger than Batavia: the same system put hail over 294 other tracked cities, 33 of them in Iowa. Nearest: Agency (5 miles west, up to 1"); Eldon (9 miles southwest, up to 0.75"); Libertyville (9 miles southeast, up to 0.75").
These maps are stills. In the app this date is one of 10 Batavia 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.
“A brief EF1 tornado... with peak winds of 90 mph... developed just south of Pekin... IA... impacting areas from Pekin Community Schools east-southeast towards Linby... (DVN)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Pekin — beyond Batavia 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
$34M
Potential roof exposure — 2,822 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 2,822 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 $593 on top of the $150 plan.
