Evidence / storm surfaces
How Imogene saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
The storm in context
Where May 17, 2026 sits in Imogene's hail record.
This was Imogene's 4th recorded hail day, arriving 24 days after the Apr 23, 2026 storm. By severity it ranks 10th of the 10 storms we have logged here. Radar put the day's largest stone over Imogene at 0" — radar-estimated size aloft.
The May 17, 2026 convective day was bigger than Imogene: the same system put hail over 894 other tracked cities, 139 of them in Iowa. Nearest: Farragut (9 miles southwest, up to 1"); Red Oak (10 miles east, up to 1"); Hastings (12 miles northwest, up to 1").
These maps are stills. In the app this date is one of 10 Imogene 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.
No ground reports were filed with the National Weather Service for this storm over Imogene. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Below the severe threshold
What 0" hail means for Imogene roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.
