Evidence / storm surfaces

How Hermann saw the hail — from two instruments

Aug 16, 2026 · Hermann, MO

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.

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.

The storm in context

Where Aug 16, 2026 sits in Hermann's hail record.

This was Hermann's 8th recorded hail day, arriving 4 days after the Aug 12, 2026 storm. By severity it ranks 5th of the 10 storms we have logged here. Radar put the day's largest stone over Hermann at 1.25" — radar-estimated size aloft.

The Aug 16, 2026 convective day was bigger than Hermann: the same system put hail over 264 other tracked cities, 33 of them in Missouri. Nearest: New Haven (15 miles southeast, up to 0.5"); Owensville (17 miles south, up to 1.25"); Chamois (20 miles west, up to 0.5").

These maps are stills. In the app this date is one of 10 Hermann 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

What people on the ground reported

No reports filed with the NWS

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.

For this storm over Hermann, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.

Damage-capable hail signal

What 1.25" hail means for Hermann 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.

1,035 homes × $12,000 avg. claim

Potential roof exposure

$12M

Potential roof exposure — 1,035 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 10, 2026.
