The 7th most severe storm Alpena has seen in the last 12 months
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.

Evidence / storm surfaces
How Alpena saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for Feb 23, 2026 — this storm produced no NEXRAD point detections over Alpena, so there is one map to show, not two.
The storm in context
Where Feb 23, 2026 sits in Alpena's hail record.
This was Alpena's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 7th of the 7 storms we have logged here. Radar put the day's largest stone over Alpena at 0.5" — radar-estimated size aloft.
The Feb 23, 2026 convective day was bigger than Alpena: the same system put hail over 3 other tracked cities, 1 of them in South Dakota. Nearest: Woonsocket (11 miles south, up to 0.5"); Stoneboro (947 miles east, up to 0.5"); Lisbon (1142 miles east, up to 0.75").
These maps are stills. In the app this date is one of 7 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.
Nobody on the ground filed a report over Alpena for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
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.
