Evidence / storm surfaces
How Marietta saw the hail — from two instruments
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 signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
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.
The storm in context
Where Apr 17, 2026 sits in Marietta's hail record.
This was Marietta's 3rd recorded hail day, arriving 15 days after the Apr 2, 2026 storm. By severity it ranks 4th of the 4 storms we have logged here. Radar put the day's largest stone over Marietta at 1" — the largest NEXRAD radar signature.
The Apr 17, 2026 convective day was bigger than Marietta: the same system put hail over 1,016 other tracked cities, 101 of them in Illinois. Nearest: Macomb (8 miles west, up to 1"); Cuba (11 miles east, up to 2"); Ipava (12 miles southeast, 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.
The National Weather Service logged no spotter reports for this storm over Marietta. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Damage-capable hail signal
What 1" hail means for Marietta roofs.
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.
