Evidence / storm surfaces
How Ralph 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 Jun 27, 2026 sits in Ralph's hail record.
This was Ralph's 2nd recorded hail day, arriving 37 days after the May 21, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Ralph at 4" — the largest NEXRAD radar signature.
The Jun 27, 2026 convective day was bigger than Ralph: the same system put hail over 587 other tracked cities, 131 of them in South Dakota. Nearest: Ludlow (10 miles west, up to 4"); Lodgepole (12 miles southeast, up to 1"); Scranton (18 miles north, up to 4").

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 Ralph. 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.
Severe hail signal
What 4" hail means for Ralph roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.
