Evidence / storm surfaces
How Jefferson saw the hail — from two instruments
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 signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
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.
The storm in context
Where Mar 15, 2026 sits in Jefferson's hail record.
This was Jefferson's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 13 storms we have logged here. Radar put the day's largest stone over Jefferson at 3.5" — the largest NEXRAD radar signature.
The Mar 15, 2026 convective day was bigger than Jefferson: the same system put hail over 695 other tracked cities, 89 of them in Texas. Nearest: Karnack (11 miles south, up to 3"); Belcher (14 miles southeast, up to 2.25"); Mooringsport (15 miles southeast, up to 3").
These maps are stills. In the app this date is one of 13 Jefferson 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 Jefferson 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.
Severe hail signal
What 3.5" hail means for Jefferson roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

What this storm is worth to a roofer.
Potential roof exposure
$1.1M
Potential roof exposure — 88 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
March 2028
Claims from this storm can typically be filed until around March 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 $18 on top of the $150 plan.
