Evidence / storm surfaces
How Salem 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 May 31, 2026 sits in Salem's hail record.
This was Salem's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 8 storms we have logged here. Radar put the day's largest stone over Salem at 2.25" — the largest NEXRAD radar signature.
The May 31, 2026 convective day was bigger than Salem: the same system put hail over 637 other tracked cities, 61 of them in South Dakota. Nearest: Canistota (10 miles southeast, up to 2.5"); Emery (12 miles southwest, up to 2"); Bridgewater (14 miles south, up to 2").
These maps are stills. In the app this date is one of 8 Salem 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.
The National Weather Service logged no spotter reports for this storm over Salem. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Severe hail signal
What 2.25" hail means for Salem 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.
