Evidence / storm surfaces
How Rochester saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for Oct 13, 2026 — this storm produced no NEXRAD point detections over Rochester, so there is one map to show, not two.
The storm in context
Where Oct 13, 2026 sits in Rochester's hail record.
This was Rochester's 9th recorded hail day, arriving 48 days after the Aug 26, 2026 storm. By severity it ranks 8th of the 9 storms we have logged here. Radar put the day's largest stone over Rochester at 0.5" — radar-estimated size aloft.
The Oct 13, 2026 convective day was bigger than Rochester: the same system put hail over 183 other tracked cities, 1 of them in Indiana. Nearest: Winamac (5 miles west, up to 0.5"); Belvidere (150 miles northwest, up to 0.5"); Rockford (154 miles northwest, up to 0.5").

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 Rochester 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.
Below the severe threshold
What 0.5" hail means for Rochester roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$156K
Potential roof exposure — 13 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
October 2028
Claims from this storm can typically be filed until around October 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 $3 on top of the $150 plan.
