Evidence / storm surfaces
How Trenary saw the hail — from two instruments
Jun 30, 2026 · Trenary, 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.
NEXRAD radar signatures Surface resolved
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

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.

The storm in context
Where Jun 30, 2026 sits in Trenary's hail record.
This was Trenary's 2nd recorded hail day, arriving 2 days after the Jun 28, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Trenary at 2.25" — the largest NEXRAD radar signature.
The Jun 30, 2026 convective day was bigger than Trenary: the same system put hail over 720 other tracked cities, 16 of them in Michigan. Nearest: Chatham (7 miles east, up to 1.75"); Eben Junction (11 miles north, up to 2.5"); Skandia (13 miles northwest, up to 1.75").

Severe hail signal
What 2.25" hail means for Trenary roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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.
