How Auburn saw the hail — from two instruments

Jul 4, 2026 · Auburn, MI

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.

Radar-estimated hail-size map of the storm over Auburn, MI on Jul 4, 2026 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.

Max size 0.5"

Only the radar-estimated size surface resolved for Jul 4, 2026 — this storm produced no NEXRAD point detections over Auburn, so there is one map to show, not two.

The storm in context

Where Jul 4, 2026 sits in Auburn's hail record.

This was Auburn's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Auburn at 0.5" — radar-estimated size aloft.

The Jul 4, 2026 convective day was bigger than Auburn: the same system put hail over 2,035 other tracked cities, 4 of them in Michigan. Nearest: Davison (51 miles southeast, up to 0.5"); Kinde (63 miles east, up to 0.5"); Port Hope (66 miles east, up to 0.5").

Ground reports

What people on the ground reported

No reports filed with the NWS

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 Auburn, 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 Auburn 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.

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.
