How Williamsport saw the hail — from two instruments

Jul 10, 2026 · Williamsport, PA

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 of the storm over Williamsport, PA on Jul 10, 2026 Estimated size field

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 10, 2026 — this storm produced no NEXRAD point detections over Williamsport, so there is one map to show, not two.

The storm in context

Where Jul 10, 2026 sits in Williamsport's hail record.

Ground reports

What people on the ground reported

No reports filed with the NWS

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 Williamsport. 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.

Below the severe threshold

What 0.5" hail means for Williamsport 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.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 2, 2026.
