Severity
The 9th most severe storm Foss 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 Foss 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 May 26, 2026 — this storm produced no NEXRAD point detections over Foss, so there is one map to show, not two.
The storm in context
Where May 26, 2026 sits in Foss's hail record.
This was Foss's 6th recorded hail day, arriving 4 days after the May 22, 2026 storm. By severity it ranks 9th of the 11 storms we have logged here. Radar put the day's largest stone over Foss at 0.5" — radar-estimated size aloft.
The May 26, 2026 convective day was bigger than Foss: the same system put hail over 259 other tracked cities, 12 of them in Oklahoma. Nearest: Granite (37 miles southwest, up to 0.5"); Mangum (48 miles southwest, up to 0.5"); Headrick (49 miles south, up to 0.5").
These maps are stills. In the app this date is one of 11 Foss 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.
For this storm over Foss, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Below the severe threshold
What 0.5" hail means for Foss 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.
