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.

Evidence / storm surfaces
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.
Estimated size field 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.
The storm in context
This was Fillmore's 3rd recorded hail day, arriving 2 days after the May 16, 2026 storm. By severity it ranks 2nd of the 8 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 (5 miles east, up to 0.75"); Maitland (9 miles northwest, up to 0.5"); Forest City (11 miles west, up to 0.5").
These maps are stills. In the app this date is one of 8 Fillmore 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.

Below the severe threshold
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Potential roof exposure — 62 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
May 2028
Claims from this storm can typically be filed until around May 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
