Evidence / storm surfaces
How Marquette 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.
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.
Only the radar-estimated size surface resolved for Jul 20, 2026 — this storm produced no NEXRAD point detections over Marquette, so there is one map to show, not two.
The storm in context
Where Jul 20, 2026 sits in Marquette's hail record.
This was Marquette's 2nd recorded hail day, arriving 8 days after the Jul 12, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Marquette at 1.25" — radar-estimated size aloft.
The Jul 20, 2026 convective day was bigger than Marquette: the same system put hail over 553 other tracked cities, 65 of them in Michigan. Nearest: Negaunee (5 miles west, up to 1.25"); Champion (16 miles southwest, up to 1.25"); Ishpeming (18 miles southwest, up to 1.25").
These maps are stills. In the app this date is one of 2 Marquette 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.

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 31 minutes, from to .
Reports came from Trowbridge Park and Negaunee — beyond Marquette itself.
Damage-capable hail signal
What 1.25" hail means for Marquette 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
$138M
Potential roof exposure — 11,524 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 58 jobs
- Illustrative work
- ~$870K
Close just 0.5% of the 11,524 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
July 2028
Claims from this storm can typically be filed until around July 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 $2,420 on top of the $150 plan.
