NEXRAD logged 0 hail signatures up to 2.5"; the estimated-size surface reached 3.75" aloft. At 3.75" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
Evidence / storm surfaces
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
The storm in context
This was Rio Grande City's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Rio Grande City at 3.75" — radar-estimated size aloft.
The Mar 7, 2026 convective day was bigger than Rio Grande City: the same system put hail over 254 other tracked cities, 75 of them in Texas. Nearest: Roma (16 miles west, up to 4"); Falcon Heights (30 miles west, up to 4"); Freer (80 miles north, up to 1.75").
These maps are stills. In the app this date is one of 7 Rio Grande City 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
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.

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 68 minutes, from to .
Reports came from Escobares — beyond Rio Grande City itself.
Severe hail signal
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.

Roofing exposure
Potential roof exposure
$122M
Potential roof exposure — 10,187 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 10,187 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
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 $2,139 on top of the $150 plan.
