Two ways to read the storm

How Hermon saw the hail — from two instruments

Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

Radar-estimated hail size
Radar-estimated hail-size map of the storm over Hermon, NY on Mar 23, 2026

Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

Only the radar-estimated size surface resolved for Mar 23, 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 23, 2026 sits in Hermon's hail record

This was Hermon's 3rd recorded hail day, arriving 20 days after the Mar 3, 2026 storm. By severity it ranks 8th of the 9 storms we have logged here. Radar put the day's largest stone over Hermon at 0.5" — radar-estimated size aloft.

The Mar 23, 2026 convective day was bigger than Hermon: the same system put hail over 2 other tracked cities. Nearest: Volcano (4996 miles west, up to 2.5"); Pahoa (5000 miles west, up to 2.5").

These maps are stills from Hermon's Mar 23, 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 Hermon, 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 Hermon 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.

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.
