Both radar surfaces caught this storm: NEXRAD logged 107 hail signatures up to 2.75", and the radar-estimated size reached 1.25" aloft. At 2.75" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.
A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
This was Curtis Bay's 4th recorded hail day, arriving 1 day after the Jul 27, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Curtis Bay at 2.75" — the largest NEXRAD radar signature.
The Jul 28, 2026 convective day was bigger than Curtis Bay: the same system put hail over 686 other tracked cities, 55 of them in Maryland. Nearest: Glen Burnie (3 miles west, up to 2.5"); Baltimore (7 miles north, up to 2.75"); Rosedale (7 miles north, up to 2.75").
These maps are stills from Curtis Bay's Jul 28, 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.

Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
