Evidence / storm surfaces
How Redfield 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 Apr 22, 2026 sits in Redfield's hail record.
This was Redfield's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 10th of the 10 storms we have logged here. Radar put the day's largest stone over Redfield at 0" — radar-estimated size aloft.
The Apr 22, 2026 convective day was bigger than Redfield: the same system put hail over 152 other tracked cities, 35 of them in South Dakota. Nearest: Orient (13 miles west, up to 1"); Rockham (14 miles north, up to 1"); Miller (23 miles west, up to 1").
These maps are stills. In the app this date is one of 10 Redfield 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 Redfield, 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.
Below the severe threshold
What 0" hail means for Redfield 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.
