Evidence / storm surfaces

How Jacksonville saw the hail — from two instruments

Jul 20, 2026 · Jacksonville, FL

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
Radar-estimated hail-size map of the storm over Jacksonville, FL on Jul 20, 2026 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 0.5"

Only the radar-estimated size surface resolved for Jul 20, 2026 — this storm produced no NEXRAD point detections over Jacksonville, so there is one map to show, not two.

The storm in context

Where Jul 20, 2026 sits in Jacksonville's hail record.

This was Jacksonville's 12th recorded hail day, arriving 9 days after the Jul 11, 2026 storm. By severity it ranks 15th of the 28 storms we have logged here. Radar put the day's largest stone over Jacksonville at 0.5" — radar-estimated size aloft.

The Jul 20, 2026 convective day was bigger than Jacksonville: the same system put hail over 553 other tracked cities, 5 of them in Florida. Nearest: Saint Augustine (30 miles southeast, up to 0.5"); Waycross (87 miles northwest, up to 0.5"); Millwood (90 miles northwest, up to 0.5").

These maps are stills. In the app this date is one of 28 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.

The National Weather Service logged no spotter reports for this storm over Jacksonville. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.

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.

Roofing exposure

What this storm is worth to a roofer.

5,517 homes × $12,000 avg. claim

Potential roof exposure

$66M

Potential roof exposure — 5,517 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Claim window

July 2028

Claims from this storm can typically be filed until around July 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 Sep 13, 2026.
