Knoxville Flooding History: Wettest Days Since 1871

Knoxville's official weather record runs from January 1, 1871 to today: the downtown weather office first, McGhee Tyson Airport now. This page pulls out the days that matter for water damage. That means every day with 1.60 in. of rain or more (the wettest 1% of the 56,912 days with a reading), the dates FEMA logged the most flood insurance claims here, and how many nights each winter fell to 20°F.

Updated

Three events, in the National Weather Service's words

Flash flooding, September 23, 2006

3.04 in. of rain

in the station record, September 23, 2006

Storms formed along a boundary between Chattanooga and Knoxville and kept crossing the same areas, with much of the rain falling in about three hours. The National Weather Service logged 4.08 inches at the Knoxville Water Plant observer site and 3.06 inches at McGhee Tyson Airport, and radar estimated up to 6 inches in parts of Knox and Loudon counties. Roads closed, people were evacuated, and flooding around Neyland Stadium delayed the start of the Tennessee-Marshall game.

Arctic cold, December 23-24, 2022

Low of 4°F

in the station record, December 23, 2022, December 24, 2022

McGhee Tyson Airport fell to 4°F on both days, with wind chills as low as -15 and -16 and a gust of 50 mph on the 23rd. Nights like these, well below the 20°F pipe-freeze mark, are when supply lines in crawl spaces and outside walls split.

Snow and deep cold, January 14-17, 2024

Low of 0°F

in the station record, January 15, 2024, January 16, 2024, January 17, 2024

The National Weather Service called it the Knoxville area's largest snowfall in one event since the Blizzard of '93. Knoxville kept 4 inches or more of snow on the ground for 7 straight days, the longest such stretch in snow-depth records back to 1910, and reached 0°F, its coldest reading in 10 years.

The loss dates with the most flood claims in Knoxville

From FEMA's National Flood Insurance Program claims for Knoxville's residential ZIP codes, with the rain the official gauge logged that day. Flash floods are local, so a day with modest rain at the airport can still flood a creek neighborhood across town. See flash flood cleanup.
