Evidence / storm surfaces
How Port Huron saw the hail — from two instruments
Sep 2, 2026 · Port Huron, 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 Surface resolved
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.
Max size
1"
Only the radar-estimated size surface resolved for Sep 2, 2026 — this storm produced no NEXRAD point detections over Port Huron, so there is one map to show, not two.
The storm in context
Where Sep 2, 2026 sits in Port Huron's hail record.
This was Port Huron'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 Port Huron at 1" — radar-estimated size aloft.
The Sep 2, 2026 convective day was bigger than Port Huron: the same system put hail over 356 other tracked cities, 37 of them in Michigan. Nearest: North Street (5 miles west, up to 1"); Avoca (10 miles west, up to 1"); Emmett (15 miles west, up to 0.75").
These maps are stills. In the app this date is one of 1 Port Huron storm date 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" hail means for Port Huron 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 Sep 3, 2026.
