How Niagara saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Where Jun 30, 2026 sits in Niagara's hail record
This was Niagara's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 2 storms we have logged here. Radar put the day's largest stone over Niagara at 1" — the largest NEXRAD radar signature.
The Jun 30, 2026 convective day was bigger than Niagara: the same system put hail over 720 other tracked cities, 111 of them in Wisconsin. Nearest: Vulcan (4 miles northeast, up to 1"); Pembine (7 miles south, up to 2"); Amberg (20 miles southwest, up to 2.25").
These maps are stills from Niagara's Jun 30, 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.
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 Niagara. 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.
What 1" hail means for Niagara roofs
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.
