Severity
The 11th most severe storm Granite has seen in the last 12 months
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
- Peak hail signal

Largest radar-indicated size — a signal of damage potential, not confirmation.

Evidence / storm surfaces
How Granite 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.
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 Oct 13, 2026 — this storm produced no NEXRAD point detections over Granite, so there is one map to show, not two.
The storm in context
Where Oct 13, 2026 sits in Granite's hail record.
This was Granite's 11th recorded hail day, arriving 13 days after the Sep 30, 2026 storm. By severity it ranks 11th of the 11 storms we have logged here. Radar put the day's largest stone over Granite at 0.5" — radar-estimated size aloft.
The Oct 13, 2026 convective day was bigger than Granite: the same system put hail over 183 other tracked cities, 20 of them in Oklahoma. Nearest: Lone Wolf (9 miles northeast, up to 0.5"); Hobart (18 miles northeast, up to 0.5"); Sentinel (21 miles north, up to 0.75").
These maps are stills. In the app this date is one of 11 Granite 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 Granite 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 Granite 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.
