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-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.
This was Batavia's 7th recorded hail day, arriving 33 days after the May 15, 2026 storm. By severity it ranks 2nd of the 8 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: Hedrick (5 miles west, up to 1"); Agency (9 miles southwest, up to 1"); Fremont (12 miles northwest, up to 0.75").
These maps are stills from Batavia's Jun 17, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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)”
— NOAA / SPC storm report
Reports came from Pekin — beyond Batavia itself.
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
