Evidence / storm surfaces
How Melrose 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 15, 2026 sits in Melrose's hail record.
This was Melrose's 3rd recorded hail day, arriving 28 days after the Apr 17, 2026 storm. By severity it ranks 11th of the 11 storms we have logged here. Radar put the day's largest stone over Melrose at 0" — radar-estimated size aloft.
The May 15, 2026 convective day was bigger than Melrose: the same system put hail over 444 other tracked cities, 236 of them in Iowa. Nearest: Moravia (8 miles east, up to 0"); Albia (10 miles northeast, up to 1"); Chariton (16 miles northwest, up to 1").
These maps are stills. In the app this date is one of 11 Melrose 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 Melrose. 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.
Below the severe threshold
What 0" hail means for Melrose 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.
