Evidence / storm surfaces
How Blue Mound 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 Apr 27, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.

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.
The National Weather Service logged no spotter reports for this storm over Blue Mound. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Damage-capable hail signal
What 1" hail means for Blue Mound 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.
