Hail in State College · Mar 22, 2026
NEXRAD logged 4 hail signatures up to 2.25"; the estimated-size surface reached 0.5" aloft. At 2.25" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How State College saw the hail — from two instruments
Mar 22, 2026 · State College, PA
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 Surface resolved
Radar signature field 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.

Radar-estimated hail size Surface resolved
Estimated size field 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.

The storm in context
Where Mar 22, 2026 sits in State College's hail record.
This was State College'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 State College at 2.25" — the largest NEXRAD radar signature.
The Mar 22, 2026 convective day was bigger than State College: the same system put hail over 409 other tracked cities, 58 of them in Pennsylvania. Nearest: Boalsburg (5 miles east, up to 2.25"); Centre Hall (10 miles east, up to 1.75"); Bellefonte (14 miles north, up to 0.75").
These maps are stills. In the app this date is one of 1 State College storm date on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.

Severe hail signal
What 2.25" hail means for State College roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 Aug 2, 2026.
