Evidence / storm surfaces
How Detroit saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Apr 29, 2026 — this storm produced no NEXRAD point detections over Detroit, so there is one map to show, not two.
The storm in context
Where Apr 29, 2026 sits in Detroit's hail record.
This was Detroit's 3rd recorded hail day, arriving 2 days after the Apr 27, 2026 storm. By severity it ranks 5th of the 10 storms we have logged here. Radar put the day's largest stone over Detroit at 0.75" — radar-estimated size aloft.
The Apr 29, 2026 convective day was bigger than Detroit: the same system put hail over 248 other tracked cities, 116 of them in Texas. Nearest: Bagwell (7 miles northeast, up to 0.5"); Bogata (15 miles southeast, up to 0.5"); Paris (17 miles west, up to 0.5").
These maps are stills. In the app this date is one of 10 Detroit 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.
For this storm over Detroit, 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.
Near the severe threshold
What 0.75" hail means for Detroit 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
$516K
Potential roof exposure — 43 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 $9 on top of the $150 plan.
