Evidence / storm surfaces
How Christmas saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Only the NEXRAD radar-signature surface resolved for May 31, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where May 31, 2026 sits in Christmas's hail record.
This was Christmas's 4th recorded hail day, arriving 19 days after the May 12, 2026 storm. By severity it ranks 13th of the 14 storms we have logged here. Radar put the day's largest stone over Christmas at 0.75" — the largest NEXRAD radar signature.
The May 31, 2026 convective day was bigger than Christmas: the same system put hail over 637 other tracked cities, 10 of them in Florida. Nearest: Satellite Beach (32 miles southeast, up to 0"); Saint Johns (116 miles north, up to 1.25"); Jacksonville (125 miles north, up to 1.25").
These maps are stills. In the app this date is one of 14 Christmas 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
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 Christmas 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.
Near the severe threshold
What 0.75" hail means for Christmas 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$12K
Potential roof exposure — 1 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
May 2028
Claims from this storm can typically be filed until around May 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $0 on top of the $150 plan.
