Evidence / storm surfaces
How Bloomfield saw the hail — from two instruments
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.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
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.
The storm in context
Where May 4, 2026 sits in Bloomfield's hail record.
This was Bloomfield's 7th recorded hail day, arriving 8 days after the Apr 26, 2026 storm. By severity it ranks 6th of the 12 storms we have logged here. Radar put the day's largest stone over Bloomfield at 0.5" — the largest NEXRAD radar signature.
The May 4, 2026 convective day was bigger than Bloomfield: the same system put hail over 428 other tracked cities, 19 of them in Iowa. Nearest: Douds (16 miles east, up to 1.5"); Keosauqua (22 miles east, up to 1.5"); Fairfield (25 miles northeast, up to 0.75").

Ground reports
What people on the ground reported
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.
For this storm over Bloomfield, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Below the severe threshold
What 0.5" hail means for Bloomfield roofs.
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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$960K
Potential roof exposure — 80 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.
Names and phones for every home in the footprint: at most $17 on top of the $150 plan.
