NEXRAD caught this storm: 6 hail signatures up to 1". The radar-estimated size surface had no signal to model this day.
A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

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.
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 Jul 21, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
This was Cape May's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Cape May at 1" — the largest NEXRAD radar signature.
The Jul 21, 2026 convective day was bigger than Cape May: the same system put hail over 703 other tracked cities, 21 of them in New Jersey. Nearest: Milford (27 miles west, up to 1"); Felton (38 miles west, up to 1"); Ocean City (42 miles south, up to 0.75").
These maps are stills from Cape May's Jul 21, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.
“Updates previous tornado report from Cape May Point. A waterspout was witnessed going on shore the beach at Cape May point. A narrow path of tree damage was noted along (PHI)”

“Video was shared on social media of a waterspout moving ashore. Time estimated from radar. (PHI)”

Reports came from Cape May Point — beyond Cape May itself.
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
