Evidence / storm surfaces
How Hanover saw the hail — from two instruments
Jul 18, 2026 · Hanover, MD
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 Surface resolved
Estimated size field 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.
Max size
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.
The storm in context
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"); Columbia (11 miles west, up to 0.75").
These maps are stills. In the app this date is one of 3 Hanover storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.

Near the severe threshold
What 0.75" hail means for Hanover roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 3, 2026.
