Hail in Houston · Apr 27, 2026
NEXRAD logged 2 hail signatures up to 2.5"; the estimated-size surface reached 1.25" aloft. At 2.5" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Houston 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.
Radar signature field 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.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
The storm in context
Where Apr 27, 2026 sits in Houston's hail record.
This was Houston's 2nd recorded hail day, arriving 43 days after the Mar 15, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Houston at 2.5" — the largest NEXRAD radar signature.
The Apr 27, 2026 convective day was bigger than Houston: the same system put hail over 1,188 other tracked cities, 305 of them in Missouri. Nearest: Raymondville (5 miles east, up to 2.5"); Elk Creek (7 miles south, up to 2.5"); Cabool (13 miles southwest, up to 2.5").

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.

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 15 minutes, from to .
Reports came from Solo, Yukon, and Simmons — beyond Houston itself.
Severe hail signal
What 2.5" hail means for Houston 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$696K
Potential roof exposure — 58 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
April 2028
Claims from this storm can typically be filed until around April 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 $12 on top of the $150 plan.
