Evidence / storm surfaces

How Jacksonville saw the hail — from two instruments

Aug 4, 2026 · Jacksonville, 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.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Jacksonville, FL on Aug 4, 2026 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.

Max size 0.5"

Only the radar-estimated size surface resolved for Aug 4, 2026 — this storm produced no NEXRAD point detections over Jacksonville, so there is one map to show, not two.

The storm in context

Where Aug 4, 2026 sits in Jacksonville's hail record.

This was Jacksonville's 17th recorded hail day, arriving 5 days after the Jul 30, 2026 storm. By severity it ranks 17th of the 26 storms we have logged here. Radar put the day's largest stone over Jacksonville at 0.5" — radar-estimated size aloft.

The Aug 4, 2026 convective day was bigger than Jacksonville: the same system put hail over 131 other tracked cities, 7 of them in Florida. Nearest: New Smyrna Beach (106 miles southeast, up to 0.75"); Vero Beach (191 miles south, up to 0.5"); Gibson (212 miles north, up to 0.5").

These maps are stills. In the app this date is one of 26 Jacksonville 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.

Ground reports

What people on the ground reported

No reports filed with the NWS

These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.

Nobody on the ground filed a report over Jacksonville for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.

Below the severe threshold

What 0.5" hail means for Jacksonville 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.

3,592 homes × $12,000 avg. claim

Potential roof exposure

$43M

Potential roof exposure — 3,592 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Claim window

August 2028

Claims from this storm can typically be filed until around August 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

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 26, 2026.
