How Columbia saw the hail — from two instruments
Jul 10, 2026 · Columbia, 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.
NEXRAD radar signatures Surface resolved
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.

Radar-estimated hail size Surface resolved
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
Where Jul 10, 2026 sits in Columbia's hail record.
This was Columbia's 6th recorded hail day, arriving 29 days after the Jun 11, 2026 storm. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Columbia at 2" — the largest NEXRAD radar signature.
The Jul 10, 2026 convective day was bigger than Columbia: the same system put hail over 682 other tracked cities, 135 of them in Missouri. Nearest: Kingdom City (11 miles east, up to 0.75"); Fulton (15 miles southeast, up to 1"); New Bloomfield (15 miles south, up to 1").
These maps are stills. In the app this date is one of 7 Columbia 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.

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.

What 2" hail means for Columbia 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.

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 Aug 15, 2026.
