61 tornadoes | News, Sports, Jobs

The devastating December 15, 2021 windstorm that cut power and caused extensive property damage produced the most tornadoes in a single day, according to reports from the National Weather Service in Des Moines.

The storm has already presented the first recorded derecho in December anywhere in the United States. And now the NWS has updated their tornado count from that day. The total number of confirmed tornadoes increased by 17 after meteorologists completed their analysis on Friday. This brings the state’s unofficial total to 61.

The previous single-day tornado record for Iowa was 35 on August 31, 2014.

“Dec. January 15, 2021 was an unprecedented and historic event for the state of Iowa,” the NWS said in its overview. “Officially, it set the new record for most tornadoes in Iowa and the most EF-2 / F-2 or stronger tornadoes in a single day in Iowa since 1950. Finally, it will beat the December record temperature record for Iowa. . “

Twenty-four tornadoes affected the greater Fort Dodge area. Eight of them landed in Webster County. The estimated peak winds for the most powerful EF-2 tornadoes in the county were between 115 and 120 mph.

An EF-2 tornado in Guthrie and Greene counties remained on the ground for 21 minutes and traveled 30.1 miles. It had a maximum width of 100 meters with estimated peak winds between 115 and 120 mph. This tornado was among the strongest to have crossed the region. He traveled from Springbrook to Bagley, Jefferson and Paton.

According to the NWS, by December 15, 2021, a total of five tornadoes had occurred in Iowa in December since 1950. All of these tornadoes have occurred in southeastern Iowa.

“Having more than 10 times as many tornadoes in a single day is unprecedented in any month, let alone December” says the NWS.

Additionally, Iowa’s all-time record temperature record of 74 degrees for Iowa in December was broken with four cities recording temperatures of 75 degrees. These cities include: Oskaloosa, Muscatine, Iowa City, and Ottumwa. The previous record was held by Thurman on December 6, 1939.
