The estimated-size surface reached 1" aloft; NEXRAD logged no point detections over Heidelberg that day. 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.

Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.

Evidence / storm surfaces
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for Apr 29, 2026 — this storm produced no NEXRAD point detections over Heidelberg, so there is one map to show, not two.
The storm in context
This was Heidelberg's 2nd recorded hail day, arriving 5 days after the Apr 24, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Heidelberg at 1" — radar-estimated size aloft.
The Apr 29, 2026 convective day was bigger than Heidelberg: the same system put hail over 248 other tracked cities, 37 of them in Mississippi. Nearest: Laurel (11 miles south, up to 1"); Stringer (19 miles west, up to 1"); Waynesboro (23 miles east, up to 0.75").
These maps are stills. In the app this date is one of 5 Heidelberg 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.
“This weak brief EF0 tornado touched down near the intersection of CR 8 and CR 31. Multiple large branches were broken off with an uprooted tree along CR 31. (JAN)”
— NOAA / SPC storm report
“A sizeable swath of wind damage developed across south-central Jasper county and moved into northeast Jones during the afternoon o April 29th. Much of this wind was in (JAN)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Sharon and Oak Bowery — beyond Heidelberg itself.
Damage-capable hail signal
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
Potential roof exposure
$37M
Potential roof exposure — 3,076 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 3,076 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
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 $646 on top of the $150 plan.
