NEXRAD logged 2 hail signatures up to 1"; the estimated-size surface reached 1.5" aloft. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

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.

Evidence / storm surfaces
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
This was Hamburg's 4th recorded hail day, arriving 25 days after the Apr 3, 2026 storm. By severity it ranks 3rd of the 12 storms we have logged here. Radar put the day's largest stone over Hamburg at 1.5" — radar-estimated size aloft.
The Apr 28, 2026 convective day was bigger than Hamburg: the same system put hail over 724 other tracked cities, 173 of them in Arkansas. Nearest: Fountain Hill (9 miles northwest, up to 1.5"); Crossett (13 miles southwest, up to 1.5"); Wilmar (19 miles northwest, up to 1").
These maps are stills. In the app this date is one of 12 Hamburg 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.
“A very brief tornado occurred along County Road 498 in Ashley County. This tornado uprooted trees and caused wooden power poles to lean. The tornado crossed County Road (JAN)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Fountain Hill — beyond Hamburg itself.
High damage potential
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
Potential roof exposure
$36K
Potential roof exposure — 3 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 $1 on top of the $150 plan.
