Evidence / storm surfaces
How Potosi 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 Jul 9, 2026 sits in Potosi's hail record.
This was Potosi's 5th recorded hail day, arriving 39 days after the May 31, 2026 storm. By severity it ranks 8th of the 9 storms we have logged here. Radar put the day's largest stone over Potosi at 1" — the largest NEXRAD radar signature.
The Jul 9, 2026 convective day was bigger than Potosi: the same system put hail over 944 other tracked cities, 140 of them in Missouri. Nearest: Belleview (9 miles southeast, up to 1"); Bixby (13 miles southwest, up to 1"); Black (14 miles south, up to 1").
These maps are stills. In the app this date is one of 9 Potosi 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.
For this storm over Potosi, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Damage-capable hail signal
What 1" hail means for Potosi 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.
