The Sioux Falls Storm are a dormant professional indoor football team based in Sioux Falls, South Dakota. The Storm joined the original Indoor Football League as an expansion team in 1999 as the Sioux Falls Cobras, and first took the field for the 2000 season. They currently participate in another iteration of the Indoor Football League; prior to that, the Storm were in United Indoor Football (UIF), where they won all four of the league's championship games. In the newer IFL, the Storm have won seven of the eleven championships in the league as of 2019.
They recently played their home games at Denny Sanford Premier Center up until 2024 due to a leasing dispute between the team and the arena. The lease was not renewed, and the Storm entered dormancy for the 2025 season. In mid-April 2014, the team announced that the 2014 season would be its last at the aging Sioux Falls Arena (also known as the Storm Shelter), originally constructed in 1961. In 2015, the Storm followed the Sioux Falls Stampede of the United States Hockey League to the newly constructed Denny Sanford Premier Center.
The team was founded in 1999 as an expansion team in the original Indoor Football League (IFL) as the Sioux Falls Cobras.
The Cobras would win their first game when they defeated the Sioux City Attack, 44âÂÂ30. In their inaugural season, the Cobras finished with an 8âÂÂ6 record and fourth in the Southern Division.
After one season in the IFL, they became members of the National Indoor Football League (NIFL) and changed their name to the Sioux Falls Storm.
The Storm hosted the 2004 NIFL championship game against the Lexington Horsemen in the Storm Shelter in front of a sellout crowd. The Horsemen won the championship game, but the Storm defeated the Horsemen a year later in the second round of the 2005 UIF playoffs in Lexington.
The Sioux Falls Storm were charter members of United Indoor Football (UIF) in 2005 and were the first UIF champions with a win over the Sioux City Bandits, 40âÂÂ38 at Sioux City. Sioux Falls won its second consecutive UIF championship in 2006 at their home ground, the Arena, defeating the Lexington Horseman 72âÂÂ64 on July 29, 2006. Quarterback Terrance Bryant was named United Bowl II MVP after throwing eight touchdowns in the match. Defensive end Nate Fluit recorded 16.5 sacks in 2005 and 15.5 in 2006.
Sioux Falls became one of the few teams in indoor football history to post a shutout, beating the Peoria Rough Riders 71âÂÂ0 on June 3, 2006.
On Saturday, August 4, 2007, the Storm defeated the Lexington Horsemen for the second United Bowl in a row, 62 to 59. With 19 seconds left to go in the game Storm quarterback Terrance Bryant threw up a prayer, and though protested by the small crowd of Horsemen fans, it was ruled a touchdown pass. With three seconds left in the game, and with the help of a frantic fan going for the game ball, the Horsemen gained 15 yards for a chance to kick a field goal and tie the game, but the kick was missed by Horsemen kicker Collin Barber.
On March 29, 2008, the Storm lost to the Omaha Beef 34âÂÂ18, ending their historic 40-game winning streak and giving them their first loss since July 15, 2005. They went on to win their fourth United Bowl later that season against the Bloomington Extreme.
On April 25, 2009, after switching to the Indoor Football League, the Storm were found in violation of the IFL's rule of not complying with regulations related to workers compensation coverage. As punishment, the team's first five wins of the 2009 season were forfeited; this resulted in a 6âÂÂ8 season, the first losing season in team history. The other three losses all came to the Billings Outlaws. In 2010, the Storm rebounded to reach the United Bowl before losing 43âÂÂ34 to the Outlaws.
After a tornado dubbed the Father's Day Tornado hit Billings' Rimrock Auto Arena on June 20, 2010, causing major damage, the Outlaws franchise folded, and their star quarterback Chris Dixon signed with the Storm. Led by Dixon, Sioux Falls scored an astounding 1022 points on the 2011 regular season, with 70 or more points in 10 games and opening with a 105âÂÂ71 win over the Kent Predators in Kent, Washington. Only twice did the Storm fall short of 50 points and both were against the Omaha Beef, who handed them a 41âÂÂ37 loss in the regular season finale after Sioux Falls had started 13âÂÂ0. The two teams met in the next game, which was the playoff opener. The Storm won it, 52âÂÂ39, then beat Green Bay 52âÂÂ12 to return to the United Bowl. Although they tied their lowest scoring game of the season, Sioux Falls rolled over the Tri-Cities Fever 37âÂÂ10 to earn the league championship after a two-year hiatus and also win its first IFL title. Dixon and the Storm dominated again in 2012, this time with a perfect 14âÂÂ0 record and 941 points in the regular season. On April 14, the Storm beat the Allen Wranglers, then featuring former NFL standout receiver Terrell Owens, 52âÂÂ45 on the road in Allen, Texas. Dixon threw his 500th career touchdown pass, when he hit James Terry with a 42-yard pass during a May 19 game against the Blizzard. Sioux Falls defeated the Lehigh Valley Steelhawks 79âÂÂ21 in the playoff opener, then again beat Green Bay in the semifinal and Tri-Cities (this time winning 59âÂÂ32) in the United Bowl.
Dixon then left, attempting to make it with the Orlando Predators of the Arena Football League. Sioux Falls did not suffer greatly in 2013 as Storm legend Terrance Bryant returned to play quarterback. Following a 10âÂÂ4 season, the Storm again prevailed in the playoffs and defeated the Nebraska Danger by a close 43âÂÂ40 score for the title. Bryant then retired again, as on January 6, 2014, it was announced that Dixon would be returning to the Storm, citing his desire to graduate from Augustana College and be close to his family. Dixon did not disappoint, leading the Storm to their eighth title in 2014. The Storm again defeated Nebraska in the United Bowl by a 63âÂÂ46 score. The Sioux Falls Storm completed its era at the Sioux Falls Arena with a 112âÂÂ14 home record including 82-3 from 2006 to 2014.
In 2015, the Storm's first season at the Denny Sanford Premier Center was very successful, completing another undefeated season at 16-0 overall, and was capped off with winning their ninth league championship by a score of 62âÂÂ27 over the Danger.
In 2016, the Storm continued their dominance. But lost their first game since the 2014 season as they lost at the Cedar Rapids Titans, 60âÂÂ57. But despite that setback, they capped off another successful season with a win over the newly minted Spokane Empire, 55âÂÂ34, to capture their tenth championship overall and their sixth IFL Championship and sixth in a row.
They returned to the championship game in 2017, but lost for the first time since the 2010 season to the Arizona Rattlers.
Prior to the 2018 season, the Storm announced they would join Champions Indoor Football (CIF) on August 30, 2017, in order to have smaller travel budget and reignite rivalries with the nearby Sioux City Bandits and Omaha Beef. However, after the IFL's offseason meetings, the Storm re-joined the IFL on October 4.
On October 30, 2024, the Storm announced that they had been evicted from Denny Sanford Premier Center after its owners had refused to offer a lease renewal. In a statement to KELO-TV, a representative for the Center noted that the arena would have to increase the team's rent to cover its own expenses and that, because the team's attendance had been on a downward trend, it would not have been fiscally feasible for either party to continue. The Storm stated they had explored other arena options but chose to suspend operations for 2025 with the hope that it would afford the team more time to negotiate an arena deal for the team's planned return in 2026.
