Evidence / storm surfaces
How Ottawa Lake 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.
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.
Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Ottawa Lake, so there is one map to show, not two.
The storm in context
Where Apr 15, 2026 sits in Ottawa Lake's hail record.
This was Ottawa Lake's 2nd recorded hail day, arriving 20 days after the Mar 26, 2026 storm. By severity it ranks 3rd of the 3 storms we have logged here. Radar put the day's largest stone over Ottawa Lake at 0.5" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Ottawa Lake: the same system put hail over 425 other tracked cities, 2 of them in Michigan. Nearest: Riga (5 miles west, up to 0.5"); Petersburg (9 miles northeast, up to 0.5"); Custar (36 miles south, up to 1").

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 Ottawa Lake, 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.
Below the severe threshold
What 0.5" hail means for Ottawa Lake 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
$3.1M
Potential roof exposure — 260 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 260 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
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.
