Evidence / storm surfaces
How Osceola 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 Apr 3, 2026 sits in Osceola's hail record.
This was Osceola's 3rd recorded hail day, arriving 19 days after the Mar 15, 2026 storm. By severity it ranks 8th of the 10 storms we have logged here. Radar put the day's largest stone over Osceola at 0.75" — the largest NEXRAD radar signature.
The Apr 3, 2026 convective day was bigger than Osceola: the same system put hail over 367 other tracked cities, 36 of them in Iowa. Nearest: Murray (6 miles northwest, up to 0.75"); Grand River (10 miles southwest, up to 1"); Truro (14 miles north, up to 0.5").
These maps are stills. In the app this date is one of 10 Osceola 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
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.
Nobody on the ground filed a report over Osceola for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Near the severe threshold
What 0.75" hail means for Osceola roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$144K
Potential roof exposure — 12 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
April 2028
Claims from this storm can typically be filed until around April 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 $3 on top of the $150 plan.
