Evidence / storm surfaces
How Riverview 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 20, 2026 — this storm produced no NEXRAD point detections over Riverview, so there is one map to show, not two.
The storm in context
Where May 20, 2026 sits in Riverview's hail record.
This was Riverview's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Riverview at 0.75" — radar-estimated size aloft.

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 Riverview, 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.
Near the severe threshold
What 0.75" hail means for Riverview roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.
