Two ways to read the storm

How Cornwall saw the hail — from two instruments

The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.

Radar-estimated hail size
Map image is still rendering for this surface.

The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.

Max size 0.5"

Only the radar-estimated size surface resolved for Jul 1, 2026 — this storm produced no NEXRAD point detections over Cornwall, so there is one map to show, not two.

The storm in context

Where Jul 1, 2026 sits in Cornwall's hail record

This was Cornwall's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Cornwall at 0.5" — radar-estimated size aloft.

The Jul 1, 2026 convective day was bigger than Cornwall: the same system put hail over 1,147 other tracked cities, 39 of them in Vermont. Nearest: Middlebury (0 miles north, up to 1"); Bridport (5 miles west, up to 1"); New Haven (7 miles north, up to 1").

These maps are stills from Cornwall's Jul 1, 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.

For this storm over Cornwall, 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.

Below the severe threshold

What 0.5" hail means for Cornwall roofs

Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.

What this storm is worth to a roofer

$1.8M

Potential roof exposure — 153 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 153 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.

Cornwall hail history

1 recorded storm day in Cornwall, VT

← All hail in Cornwall
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 1, 2026.
