Evidence / storm surfaces
How Quimby 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.
Only the NEXRAD radar-signature surface resolved for Jun 30, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Jun 30, 2026 sits in Quimby's hail record.
This was Quimby's 3rd recorded hail day, arriving 43 days after the May 18, 2026 storm. By severity it ranks 4th of the 4 storms we have logged here. Radar put the day's largest stone over Quimby at 1" — the largest NEXRAD radar signature.
The Jun 30, 2026 convective day was bigger than Quimby: the same system put hail over 720 other tracked cities, 85 of them in Iowa. Nearest: Cherokee (12 miles northeast, up to 1"); Kingsley (15 miles west, up to 1.5"); Aurelia (15 miles northeast, up to 1").
These maps are stills. In the app this date is one of 4 Quimby 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 Quimby, 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 Quimby 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.
