Same-day SPC storm reports through 2026-10-01, before NCEI compiles the final record: 7 reports ≥1″ on 4 days, up to 1.50". Preliminary counts shift as reports are quality-controlled; they are labeled preliminary in every report we generate.

|---|---|---|---|
| June 22, 2026 | 3 | 1.50" | 1 NE Burlington Twp, 1 N Upper Uwchlan Twp |

Wind context: the record also holds 175 thunderstorm-wind events ≥50 kt (≈58 mph, the NWS severe criterion) in this radius for 2026 — relevant where the dispute is wind vs hail causation.

Provenance
Final counts: NCEI Storm Events Database, file vintage c20260918, hail events with recorded magnitude ≥1.00″ and point coordinates within 35 miles of the Philadelphia anchor. Preliminary counts: SPC daily storm reports through 2026-10-01. NWS records are point and path observations. The absence of a nearby report does NOT prove that no hail fell at this address — it means no observation was logged nearby. A report of nearby hail documents the event; it does not by itself prove damage to a specific structure. Spotted an error? Email the address on our terms page and we correct against the source.
