Evidence / storm surfaces
How Gainesville saw the hail — from two instruments
Aug 20, 2026 · Gainesville, FL
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 Aug 20, 2026 sits in Gainesville's hail record.
This was Gainesville's 12th recorded hail day, arriving 1 day after the Aug 19, 2026 storm. By severity it ranks 8th of the 14 storms we have logged here. Radar put the day's largest stone over Gainesville at 0.5" — radar-estimated size aloft.
The Aug 20, 2026 convective day was bigger than Gainesville: the same system put hail over 640 other tracked cities, 77 of them in Florida. Nearest: Newberry (14 miles southwest, up to 0.5"); Lake Butler (21 miles north, up to 0.75"); Williston (21 miles south, up to 0.5").
These maps are stills. In the app this date is one of 14 Gainesville 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.

Below the severe threshold
What 0.5" hail means for Gainesville 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.

Roofing exposure
What this storm is worth to a roofer.
463 homes × $12,000 avg. claim
Potential roof exposure
$5.6M
Potential roof exposure — 463 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 463 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window

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 30, 2026.
