Evidence / storm surfaces
How Dayton 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.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Only the NEXRAD radar-signature surface resolved for May 26, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where May 26, 2026 sits in Dayton's hail record.
This was Dayton's 6th recorded hail day, arriving 16 days after the May 10, 2026 storm. By severity it ranks 7th of the 11 storms we have logged here. Radar put the day's largest stone over Dayton at 1" — the largest NEXRAD radar signature.
The May 26, 2026 convective day was bigger than Dayton: the same system put hail over 259 other tracked cities, 139 of them in Texas. Nearest: Cleveland (18 miles north, up to 1"); Houston (28 miles west, up to 0"); Chappell Hill (72 miles west, up to 1").
These maps are stills. In the app this date is one of 11 Dayton 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 Dayton, 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.
Damage-capable hail signal
What 1" hail means for Dayton roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.
