How Hanover saw the hail — from two instruments
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.
Radar-estimated hail size
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.

0.75"
Only the radar-estimated size surface resolved for Jul 18, 2026 — this storm produced no NEXRAD point detections over Hanover, so there is one map to show, not two.
Where Jul 18, 2026 sits in Hanover's hail record
This was Hanover's 3rd recorded hail day, arriving 1 day after the Jul 17, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Hanover at 0.75" — radar-estimated size aloft.
The Jul 18, 2026 convective day was bigger than Hanover: the same system put hail over 377 other tracked cities, 24 of them in Maryland. Nearest: Millersville (9 miles southeast, up to 0.75"); Severna Park (9 miles southeast, up to 0.75"); Baltimore (11 miles northeast, up to 0.75").
These maps are stills from Hanover's Jul 18, 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

What 0.75" hail means for Hanover roofs
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.

Other storms in Hanover
A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
