Two ways to read the storm

How Saint Joseph 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.

Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Max size 0.5" Detections 3

Only the NEXRAD radar-signature surface resolved for Apr 3, 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 Apr 3, 2026 sits in Saint Joseph's hail record

This was Saint Joseph's 3rd recorded hail day, arriving 3 days after the Mar 31, 2026 storm. By severity it ranks 6th of the 8 storms we have logged here. Radar put the day's largest stone over Saint Joseph at 0.5" — the largest NEXRAD radar signature.

The Apr 3, 2026 convective day was bigger than Saint Joseph: the same system put hail over 367 other tracked cities, 18 of them in Missouri. Nearest: De Kalb (12 miles southwest, up to 1"); Rushville (15 miles southwest, up to 1"); Atchison (19 miles southwest, up to 1").

These maps are stills from Saint Joseph's Apr 3, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

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 Saint Joseph, 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 0.5" hail means for Saint Joseph roofs

Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.

A storm day here is a convective day — it runs from noon to noon UTC, so late-night hail is grouped with the afternoon storm that spawned it rather than split across two calendar dates. Ground reports are public-domain observations from the NOAA Storm Prediction Center. Radar surfaces are detections and estimates, not confirmed damage. Last updated Aug 3, 2026.
