Evidence / storm surfaces
How Saint Louis 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.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for Aug 16, 2026 — this storm produced no NEXRAD point detections over Saint Louis, so there is one map to show, not two.
The storm in context
Where Aug 16, 2026 sits in Saint Louis's hail record.
This was Saint Louis's 15th recorded hail day, arriving 20 days after the Jul 27, 2026 storm. By severity it ranks 9th of the 15 storms we have logged here. Radar put the day's largest stone over Saint Louis at 1" — radar-estimated size aloft.
The Aug 16, 2026 convective day was bigger than Saint Louis: the same system put hail over 264 other tracked cities, 33 of them in Missouri. Nearest: Saint Charles (5 miles west, up to 0.75"); Eureka (15 miles south, up to 0.5"); Pacific (18 miles southwest, up to 0.5").
These maps are stills. In the app this date is one of 15 Saint Louis 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
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.
Nobody on the ground filed a report over Saint Louis for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Damage-capable hail signal
What 1" hail means for Saint Louis 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$369M
Potential roof exposure — 30,736 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 154 jobs
- Illustrative work
- ~$2.3M
Close just 0.5% of the 30,736 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
August 2028
Claims from this storm can typically be filed until around August 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $6,455 on top of the $150 plan.
