2019 · On this date in other years · The biggest severe wind days

A report is a single damage or measurement report to the National Weather Service. Several reports can describe one gust front, so reports are not storms.
Reporting has grown with population, spotter networks and the internet, so counts from different decades are not directly comparable.
Thunderstorm wind reports start at 50 knots (58 mph). SPC began flagging measured against estimated speeds in 2006; earlier reports are shown as estimated.

Storm Prediction Center severe weather database, 1955 to 2025. A day is SPC’s calendar date in Central Standard Time; a severe wind day here has 300 or more damaging wind reports, or 15 or more of 75 knots (86 mph) or more.
