Hail in Maryville May 18, 2026
Both radar surfaces caught this storm: NEXRAD logged 15 hail signatures up to 2.75", and the radar-estimated size reached 1.5" aloft. At 2.75" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Maryville 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.
NEXRAD radar signatures
The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

Where May 18, 2026 sits in Maryville's hail record
This was Maryville's 5th recorded hail day, arriving 2 days after the May 16, 2026 storm. By severity it ranks 1st of the 8 storms we have logged here. Radar put the day's largest stone over Maryville at 2.75" — the largest NEXRAD radar signature.
The May 18, 2026 convective day was bigger than Maryville: the same system put hail over 726 other tracked cities, 59 of them in Missouri. Nearest: Burlington Junction (13 miles northwest, up to 2.5"); Skidmore (13 miles west, up to 2"); Maitland (13 miles southwest, up to 0.5").
These maps are stills from Maryville's May 18, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

What 2.75" hail means for Maryville roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 2, 2026.
