Hail in Corsica Jul 25, 2026

Hit 9 days ago

Both radar surfaces caught this storm: NEXRAD logged 5 hail signatures up to 1.25", and the radar-estimated size reached 0.5" aloft.

Two ways to read the storm

How Corsica 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 Jul 25, 2026 sits in Corsica's hail record

This was Corsica's 4th recorded hail day, arriving 23 days after the Jul 2, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Corsica at 1.25" — the largest NEXRAD radar signature.

The Jul 25, 2026 convective day was bigger than Corsica: the same system put hail over 303 other tracked cities, 102 of them in South Dakota. Nearest: Stickney (9 miles northwest, up to 1.25"); Harrison (12 miles northwest, up to 0.5"); Parkston (15 miles east, up to 1.75").

These maps are stills from Corsica's Jul 25, 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.

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 Corsica 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.

Shingle-bruising hail

What 1.25" hail means for Corsica roofs

Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.

What this storm is worth to a roofer

$1.5M

Potential roof exposure — 127 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 127 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.
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Other storms in Corsica

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 3, 2026.
