Largest hailstone — the top predictor of roof damage.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for May 18, 2026 — this storm produced no NEXRAD point detections over Fillmore, so there is one map to show, not two.
This was Fillmore's 3rd recorded hail day, arriving 2 days after the May 16, 2026 storm. By severity it ranks 2nd of the 6 storms we have logged here. Radar put the day's largest stone over Fillmore at 0.5" — radar-estimated size aloft.
The May 18, 2026 convective day was bigger than Fillmore: the same system put hail over 726 other tracked cities, 59 of them in Missouri. Nearest: Savannah (8 miles east, up to 0.75"); Forest City (11 miles west, up to 0.5"); Wathena (15 miles south, up to 0.5").
These maps are stills from Fillmore's May 18, 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.

Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.
