Tornadoes by decade in Pennsylvania
All tornado reports against only the strong ones (F2 and above). Averages are per year over the years the federal record covers completely — 1952, 1976 and 1993 are each missing whole months in NOAA’s own files and are left out.
| Decade | All reports | Strong (F2+) | All per year | Strong per year |
|---|---|---|---|---|
| 1950s | 57 | 33 | 6 | 4 |
| 1960s | 42 | 23 | 4 | 2 |
| 1970s | 98 | 28 | 11 | 3 |
| 1980s | 159 | 82 | 16 | 8 |
| 1990s | 217 | 37 | 24 | 4 |
| 2000s | 112 | 8 | 11 | 1 |
| 2010s | 208 | 24 | 21 | 2 |
The 2020s are left out because the decade is not finished. Reports are counted per county, so one tornado crossing a county line can appear more than once.
