Evidence / storm surfaces
How Alpena saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Jul 15, 2026 — this storm produced no NEXRAD point detections over Alpena, so there is one map to show, not two.
The storm in context
Where Jul 15, 2026 sits in Alpena's hail record.
This was Alpena's 5th recorded hail day, arriving 5 days after the Jul 10, 2026 storm. By severity it ranks 8th of the 9 storms we have logged here. Radar put the day's largest stone over Alpena at 0.5" — radar-estimated size aloft.
The Jul 15, 2026 convective day was bigger than Alpena: the same system put hail over 114 other tracked cities, 11 of them in Michigan. Nearest: Port Hope (83 miles southeast, up to 0.5"); Palms (105 miles south, up to 0.5"); Carson City (140 miles southwest, up to 0.5").
These maps are stills. In the app this date is one of 9 Alpena 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.
Ground reports
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.
The National Weather Service logged no spotter reports for this storm over Alpena. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Below the severe threshold
What 0.5" hail means for Alpena 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.
