Evidence / storm surfaces
How Joplin saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for Jul 18, 2026 — this storm produced no NEXRAD point detections over Joplin, so there is one map to show, not two.
The storm in context
Where Jul 18, 2026 sits in Joplin's hail record.
This was Joplin's 2nd recorded hail day, arriving 66 days after the May 13, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Joplin at 1" — radar-estimated size aloft.
The Jul 18, 2026 convective day was bigger than Joplin: the same system put hail over 377 other tracked cities, 8 of them in Montana. Nearest: Gildford (30 miles southeast, up to 0.5"); Chester (31 miles south, up to 1"); Conrad (55 miles southwest, up to 1").
These maps are stills. In the app this date is one of 3 Joplin 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.
Nobody on the ground filed a report over Joplin for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Damage-capable hail signal
What 1" hail means for Joplin 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$396K
Potential roof exposure — 33 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
July 2028
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $7 on top of the $150 plan.
