Running count

2020 against the years around it and the 1991 to 2020 average

20201991 to 2020 average2015 to 2025 (other years)

1,090 tornadoes in 2020, 11% below the 1991 to 2020 average of 1,231.

Counts by storm day (12Z to 12Z). Reporting changed a great deal over the decades, so years far from 1991 to 2020 are not a like-for-like comparison with the average.

Storm days. A day here runs from 12Z to 12Z (6 a.m. CST to 6 a.m. CST the next morning), the way SPC counts storm days, so an overnight tornado counts with the afternoon and evening before it.
Reporting changed over time. Tornado counts rose from the 1990s on as Doppler radar, spotter networks and cameras caught more weak tornadoes. Counts from different decades are not directly comparable, especially for the weakest ratings.
F and EF ratings. The Enhanced Fujita (EF) Scale replaced the Fujita (F) Scale on 02/01/07. Both estimate wind speed from damage, but they use different damage indicators, so each rating is shown with its own scale.
