Evidence / storm surfaces
How Sylvania saw the hail — from two instruments
Aug 10, 2026 · Sylvania, OH
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Max size
1"
Only the radar-estimated size surface resolved for Aug 10, 2026 — this storm produced no NEXRAD point detections over Sylvania, so there is one map to show, not two.
The storm in context
Where Aug 10, 2026 sits in Sylvania's hail record.
This was Sylvania's 2nd recorded hail day, arriving 38 days after the Jul 3, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Sylvania at 1" — radar-estimated size aloft.
The Aug 10, 2026 convective day was bigger than Sylvania: the same system put hail over 616 other tracked cities, 194 of them in Ohio. Nearest: Metamora (5 miles west, up to 1"); Swanton (11 miles south, up to 1"); Delta (12 miles southwest, up to 1.25").
These maps are stills. In the app this date is one of 2 Sylvania 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.

Damage-capable hail signal
What 1" hail means for Sylvania 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.
4,951 homes × $12,000 avg. claim
Potential roof exposure
$59M
Potential roof exposure — 4,951 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 25 jobs
- Illustrative work
- ~$375K
Close just 0.5% of the 4,951 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

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 11, 2026.
