NEXRAD logged 56 hail signatures up to 4"; the estimated-size surface reached 2.5" aloft. At 4" — softball or larger — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
Evidence / storm surfaces
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
This was Springfield's 3rd recorded hail day, arriving 1 day after the Apr 27, 2026 storm. By severity it ranks 1st of the 10 storms we have logged here. Radar put the day's largest stone over Springfield at 4" — the largest NEXRAD radar signature.
The Apr 28, 2026 convective day was bigger than Springfield: the same system put hail over 724 other tracked cities, 115 of them in Missouri. Nearest: Fair Grove (7 miles north, up to 4"); Bolivar (15 miles north, up to 1"); Buffalo (15 miles north, up to 0.5").
These maps are stills. In the app this date is one of 10 Springfield 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
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.

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
The storm tracked east at roughly 5 mph, based on the timing of ground reports.
Hail was reported over 139 minutes, from to .
Reports came from Willard, Glidewell, Bois D'Arc, Nixa, Boaz, and Galloway — beyond Springfield itself.
Severe hail signal
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.
Radar reading · not confirmed damage
Roofing exposure
Potential roof exposure
$363M
Potential roof exposure — 30,242 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 30,242 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
April 2028
Claims from this storm can typically be filed until around April 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 $6,351 on top of the $150 plan.
