How Negaunee saw the hail — from two instruments

Jul 20, 2026 · Negaunee, MI

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 over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Max size 1.25"

Only the radar-estimated size surface resolved for Jul 20, 2026 — this storm produced no NEXRAD point detections over Negaunee, so there is one map to show, not two.

The storm in context

Where Jul 20, 2026 sits in Negaunee's hail record.

This was Negaunee's 3rd recorded hail day, arriving 8 days after the Jul 12, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Negaunee at 1.25" — radar-estimated size aloft.

The Jul 20, 2026 convective day was bigger than Negaunee: the same system put hail over 553 other tracked cities, 65 of them in Michigan. Nearest: Marquette (5 miles east, up to 1.25"); Champion (12 miles southwest, up to 1.25"); Ishpeming (14 miles southwest, up to 1.25").

These maps are stills. In the app this date is one of 3 Negaunee 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.

Damage-capable hail signal

What 1.25" hail means for Negaunee 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.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 3, 2026.
