Evidence / storm surfaces
How Hiawatha saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
The storm in context
Where Apr 11, 2026 sits in Hiawatha's hail record.
This was Hiawatha's 4th recorded hail day, arriving 11 days after the Mar 31, 2026 storm. By severity it ranks 14th of the 21 storms we have logged here. Radar put the day's largest stone over Hiawatha at 0.5" — radar-estimated size aloft.
The Apr 11, 2026 convective day was bigger than Hiawatha: the same system put hail over 134 other tracked cities, 37 of them in Kansas. Nearest: Morrill (11 miles northwest, up to 0.5"); Sabetha (13 miles west, up to 0.5"); Craig (19 miles northeast, up to 1.75").
These maps are stills. In the app this date is one of 21 Hiawatha 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 Hiawatha 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.
Below the severe threshold
What 0.5" hail means for Hiawatha 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
$1.2M
Potential roof exposure — 99 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 $21 on top of the $150 plan.
