Evidence / storm surfaces
How Mchenry 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 Sep 6, 2026 — this storm produced no NEXRAD point detections over Mchenry, so there is one map to show, not two.
The storm in context
Where Sep 6, 2026 sits in Mchenry's hail record.
This was Mchenry's 6th recorded hail day, arriving 3 days after the Sep 3, 2026 storm. By severity it ranks 5th of the 6 storms we have logged here. Radar put the day's largest stone over Mchenry at 0.75" — radar-estimated size aloft.
The Sep 6, 2026 convective day was bigger than Mchenry: the same system put hail over 608 other tracked cities, 69 of them in North Dakota. Nearest: Binford (12 miles east, up to 0.75"); Aneta (27 miles east, up to 0.75"); Buchanan (33 miles south, up to 0.75").

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 Mchenry 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.
Near the severe threshold
What 0.75" hail means for Mchenry 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
$1.6M
Potential roof exposure — 136 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 136 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
September 2028
Claims from this storm can typically be filed until around September 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 $29 on top of the $150 plan.
