Evidence / storm surfaces
How Alta Vista 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 17, 2026 sits in Alta Vista's hail record.
This was Alta Vista's 6th recorded hail day, arriving 13 days after the May 4, 2026 storm. By severity it ranks 18th of the 19 storms we have logged here. Radar put the day's largest stone over Alta Vista at 1" — the largest NEXRAD radar signature.
The May 17, 2026 convective day was bigger than Alta Vista: the same system put hail over 894 other tracked cities, 134 of them in Kansas. Nearest: White City (15 miles southwest, up to 1"); Junction City (19 miles west, up to 1"); Eskridge (20 miles east, up to 0").
These maps are stills. In the app this date is one of 19 Alta Vista 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 Alta Vista. 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.
Damage-capable hail signal
What 1" hail means for Alta Vista 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.
