Two ways to read the storm

How Hermon 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.

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 Mar 3, 2026 — this storm produced no NEXRAD point detections over Hermon, so there is one map to show, not two.

The storm in context

Where Mar 3, 2026 sits in Hermon's hail record

This was Hermon's 2nd recorded hail day, arriving 33 days after the Jan 29, 2026 storm. By severity it ranks 4th of the 9 storms we have logged here. Radar put the day's largest stone over Hermon at 0.75" — radar-estimated size aloft.

The Mar 3, 2026 convective day was bigger than Hermon: the same system put hail over 80 other tracked cities, 2 of them in New York. Nearest: Lisbon (14 miles north, up to 0.5"); Madrid (21 miles north, up to 0.5"); Kinde (383 miles west, up to 0.5").

These maps are stills from Hermon's Mar 3, 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.

The National Weather Service logged no spotter reports for this storm over Hermon. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.

Near the severe threshold

What 0.75" hail means for Hermon roofs

Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.

What this storm is worth to a roofer

$1.1M

Potential roof exposure — 88 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claims from this storm can typically be filed until around March 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Other storms in Hermon

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.
