Evidence / storm surfaces
How Trenton saw the hail — from two instruments
May 16, 2026 · Trenton, MO
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

The storm in context
Where May 16, 2026 sits in Trenton's hail record.
This was Trenton's 4th recorded hail day, arriving 29 days after the Apr 17, 2026 storm. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Trenton at 4" — the largest NEXRAD radar signature.
The May 16, 2026 convective day was bigger than Trenton: the same system put hail over 711 other tracked cities, 114 of them in Missouri. Nearest: Spickard (7 miles north, up to 2.5"); Galt (8 miles east, up to 3.5"); Laredo (9 miles southeast, up to 4").
These maps are stills. In the app this date is one of 7 Trenton 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.

Storm forensics
How the storm moved
Timing and place names from NOAA ground reports
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 380 minutes, from to .
Reports came from Spickard, Laredo, Galt, Tindall, and Brimson — beyond Trenton itself.
Severe hail signal
What 4" hail means for Trenton roofs.
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.

Roofing exposure
What this storm is worth to a roofer.
3,872 homes × $12,000 avg. claim
Potential roof exposure

Close just 0.5% of the 3,872 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

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 16, 2026.
