Evidence / storm surfaces
How Manson saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
The storm in context
Where May 17, 2026 sits in Manson's hail record.
This was Manson's 3rd recorded hail day, arriving 2 days after the May 15, 2026 storm. By severity it ranks 7th of the 9 storms we have logged here. Radar put the day's largest stone over Manson at 1" — the largest NEXRAD radar signature.
The May 17, 2026 convective day was bigger than Manson: the same system put hail over 894 other tracked cities, 139 of them in Iowa. Nearest: Rockwell City (16 miles southwest, up to 1"); Pocahontas (17 miles northwest, up to 1"); Rolfe (17 miles north, up to 0").

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 Manson 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.
Damage-capable hail signal
What 1" hail means for Manson 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$1.1M
Potential roof exposure — 92 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 $19 on top of the $150 plan.
