Evidence / storm surfaces
How Maroa saw the hail — from two instruments
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
Where May 4, 2026 sits in Maroa's hail record.
This was Maroa's 2nd recorded hail day, arriving 7 days after the Apr 27, 2026 storm. By severity it ranks 4th of the 7 storms we have logged here. Radar put the day's largest stone over Maroa at 1" — the largest NEXRAD radar signature.
The May 4, 2026 convective day was bigger than Maroa: the same system put hail over 428 other tracked cities, 239 of them in Illinois. Nearest: Kenney (9 miles northwest, up to 1"); Decatur (11 miles south, up to 1"); Beason (17 miles northwest, up to 1").
These maps are stills. In the app this date is one of 7 Maroa 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
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 Maroa. 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 Maroa 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.
