How Trenton saw the hail — from two instruments

Jun 10, 2026 · Trenton, MO

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-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Trenton, MO on Jun 10, 2026 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.

Max size 1.25"

Only the radar-estimated size surface resolved for Jun 10, 2026 — this storm produced no NEXRAD point detections over Trenton, so there is one map to show, not two.

The storm in context

Where Jun 10, 2026 sits in Trenton's hail record.

This was Trenton's 6th recorded hail day, arriving 4 days after the Jun 6, 2026 storm. By severity it ranks 3rd of the 7 storms we have logged here. Radar put the day's largest stone over Trenton at 1.25" — radar-estimated size aloft.

The Jun 10, 2026 convective day was bigger than Trenton: the same system put hail over 777 other tracked cities, 105 of them in Missouri. Nearest: Spickard (7 miles north, up to 1.25"); Galt (8 miles east, up to 1"); Laredo (9 miles southeast, up to 0.75").

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.

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.

Reports came from Laredo — beyond Trenton itself.

Damage-capable hail signal

What 1.25" hail means for Trenton 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.

8,253 homes × $12,000 avg. claim

Potential roof exposure

$99M

Potential roof exposure — 8,253 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

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.
