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.
Radar-estimated hail size
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.
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"); Ishpeming (18 miles southwest, up to 1.25"); Champion (19 miles west, up to 1.25").
These maps are stills from Marquette's Jul 20, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.

Reports came from Trowbridge Park and Negaunee — beyond Marquette itself.
What 1.25" hail means for Marquette roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
What this storm is worth to a roofer
$138M
Potential roof exposure — 11,524 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
