Evidence / storm surfaces
How Alma 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.
Only the NEXRAD radar-signature surface resolved for Mar 31, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Mar 31, 2026 sits in Alma's hail record.
This was Alma's 3rd recorded hail day, arriving 25 days after the Mar 6, 2026 storm. By severity it ranks 18th of the 18 storms we have logged here. Radar put the day's largest stone over Alma at 0" — radar-estimated size aloft.
The Mar 31, 2026 convective day was bigger than Alma: the same system put hail over 522 other tracked cities, 43 of them in Kansas. Nearest: Wamego (16 miles northeast, up to 0"); Mayetta (42 miles northeast, up to 0"); Vermillion (46 miles north, up to 0").
These maps are stills. In the app this date is one of 18 Alma 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 Alma, 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 Alma 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.
