Northern Colorado Hailstorm

There are three other professional soccer teams in the state of Colorado. Colorado Rapids play in Major League Soccer, Colorado Springs Switchbacks play in USL Championship and Colorado Rapids 2 play in MLS Next Pro.

Because USL League One had an uneven number of teams for the 2022 season, Northern Colorado played the first competitive match in its history in the U.S. Open Cup on April 6 of that year, against the Colorado Springs Switchbacks. Despite losing Irvin Parra to a red card in the 27th minute, the Hailstorm won 1–0 in extra time, with Jerry Desdunes scoring their first-ever goal in the 96th. On April 9, 2022, Ethan Vanacore-Decker scored the first league goal for the Hailstorm play during their inaugural USL League One match which finished in a 1–1 draw with Richmond Kickers. In just its fourth ever competitive match, the Hailstorm defeated Major League Soccer side Real Salt Lake away from home by a score of 1–0 on April 20, 2022, to advance to the fourth round of the U.S. Open Cup. The Hailstorm were eliminated from cup competition on May 11, 2022 by fellow League One opponents Union Omaha by a score of 2-0 in the round of 32. The Hailstorm played their first home game against North Carolina FC on June 8, 2022, after 10 games (including cup matches) on the road while awaiting a home venue in Colorado. The game took place at Jackson Stadium, on the campus of the University of Northern Colorado, since the completion of TicketSmarter Stadium was delayed. The game saw Irvin Parra score the Hailstorm's first home goal in spectacular fashion, making #2 on ESPN's top ten list that evening. The Hailstorm would go on the finish the match in a 1-1 draw.

During the 2024 season of USL League One, the United Soccer League would introduce the USL Jägermeister Cup (also known as the USL Cup). The inaugural edition would only be competed among USL League One teams. Despite heading into the tournament in bad form, the Hailstorm would surprise the league with a first-place finish in the West Group. They won seven of eight games and finished with 21 points. In the first stage of the knockouts, they matched up with their rivals Union Omaha. Despite an even split in the group stage, Hailstorm would win 2-0 to secure a place in the finals. Northern Colorado would meet Forward Madison in the final, defeating them 1(5)-1(4) thanks to a saved shot by goalkeeper Edward Delgado and becoming the inaugural USL Jägermeister Cup champions.

During the 2024 USL League One season, it would be revealed that owner Jeff Katofsky was under legal fire. His ongoing project, the Future Legends Complex, was behind on $13 million in payments. Kartofsky and the complex also had $11.3 million in open legal claims filed against them. On October 16, 2024, Kartofsky would file for bankruptcy. On November 14, 2024, it was announced by USL League One that Northern Colorado Hailstorm's franchise agreement had been terminated. The club's ownership responded the same day, stating their intentions to continue playing at the Future Legends Complex in 2025. On April 7, 2025, The League for Clubs announced that the Hailstorm had joined for the 2025 season.
