Evidence / storm surfaces
How Appleton saw the hail — from two instruments
Jul 1, 2026 · Appleton, NY
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 1, 2026 sits in Appleton's hail record.
This was Appleton's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 5th of the 5 storms we have logged here. Radar put the day's largest stone over Appleton at 0.75" — radar-estimated size aloft.
The Jul 1, 2026 convective day was bigger than Appleton: the same system put hail over 1,147 other tracked cities, 121 of them in New York. Nearest: Spencerport (41 miles east, up to 1.25"); Bradford (98 miles southeast, up to 0.5"); Lansing (112 miles southeast, up to 1.25").
These maps are stills. In the app this date is one of 5 Appleton 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 Appleton 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 Sep 3, 2026.
