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.
Only the NEXRAD radar-signature surface resolved for Apr 23, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Apr 23, 2026 sits in Osceola's hail record.
This was Osceola's 5th recorded hail day, arriving 8 days after the Apr 15, 2026 storm. By severity it ranks 9th of the 10 storms we have logged here. Radar put the day's largest stone over Osceola at 1" — the largest NEXRAD radar signature.
The Apr 23, 2026 convective day was bigger than Osceola: the same system put hail over 703 other tracked cities, 252 of them in Iowa. Nearest: Murray (6 miles northwest, up to 0"); Weldon (7 miles south, up to 1"); Grand River (10 miles southwest, up to 0").
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.
No ground reports were filed with the National Weather Service for this storm over Osceola. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Damage-capable hail signal
What 1" hail means for Osceola roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.
