Hail in Sherman Apr 25, 2026
Both radar surfaces caught this storm: NEXRAD logged 0 hail signatures up to 4", and the radar-estimated size reached 3.75" aloft. At 4" — softball or larger — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Sherman saw the hail — from two instruments
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.
NEXRAD radar signatures
NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Where Apr 25, 2026 sits in Sherman's hail record
This was Sherman's 4th recorded hail day, arriving 10 days after the Apr 15, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Sherman at 4" — the largest NEXRAD radar signature.
The Apr 25, 2026 convective day was bigger than Sherman: the same system put hail over 392 other tracked cities, 49 of them in Texas. Nearest: Pottsboro (11 miles north, up to 2.5"); Denison (12 miles east, up to 2.5"); Tioga (13 miles southwest, up to 0").
These maps are stills from Sherman's Apr 25, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.

How the storm moved
The storm tracked southeast at roughly 10 mph, based on the timing of ground reports.
Hail was reported over 111 minutes, from to .
Reports came from Pottsboro and Bells — beyond Sherman itself.
What 4" hail means for Sherman roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
What this storm is worth to a roofer

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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 2, 2026.
