Evidence / storm surfaces
How Stamford saw the hail — from two instruments
Jul 4, 2026 · Stamford, CT
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 Surface resolved
Radar signature field 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.

Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

The storm in context
Where Jul 4, 2026 sits in Stamford's hail record.
This was Stamford'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 Stamford at 0.5" — radar-estimated size aloft.
The Jul 4, 2026 convective day was bigger than Stamford: the same system put hail over 2,035 other tracked cities, 23 of them in Connecticut. Nearest: Huntington (9 miles southeast, up to 1"); Locust Valley (9 miles southwest, up to 0.5"); Northport (13 miles southeast, up to 1").
These maps are stills. In the app this date is one of 1 Stamford storm date 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.

Below the severe threshold
What 0.5" hail means for Stamford roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

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 1, 2026.
