Largest hailstone — the top predictor of roof damage.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
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.
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.
This was Heidelberg's 2nd recorded hail day, arriving 5 days after the Apr 24, 2026 storm. By severity it ranks 1st of the 3 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 (5 miles southwest, up to 1"); Stringer (9 miles west, up to 1"); Bay Springs (14 miles northwest, up to 1.25").
These maps are stills from Heidelberg's Apr 29, 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.
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)”

“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)”

Reports came from Sharon and Oak Bowery — beyond Heidelberg itself.
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
