The city's professional baseball history dates back to 1879 with the formation of the Omaha Green Stockings, who were charter members of the Northwestern League.

[12] Managed by Jack McKeon in their inaugural 1969 season,[13] the Royals won the American Association championship with an 85–55 record, six games ahead of the second-place Tulsa Oilers.

[17] McKeon won a second Manager of the Year Award, and outfielder George Spriggs was selected as the AA Most Valuable Player (MVP).

[15] Though Omaha was unable to qualify for the playoffs over the next five seasons, two Royals were chosen for league awards during this stretch: second baseman Jim Wohlford as the 1972 Rookie of the Year and Mark Littell as the 1973 Most Valuable Pitcher.

[15] Many players from those early teams helped the Major League Royals win four out of five AL West titles from 1976 to 1980, culminating in a World Series appearance in 1980.

[15] Behind manager John Sullivan,[20] Omaha won the 1978 Western Division title before winning their third American Association championship over the Indianapolis Indians, 4–1.

[15] In February 1985, Kansas City sold the Omaha Royals to Chicago businessman Irving "Gus" Cherry for an undisclosed sum, citing financial losses from operating their own Triple-A club; their major league affiliation continued.

[15] Then, manager Sal Rende guided the team to a fourth American Association title with a 3–2 series win over the Nashville Sounds in 1990.

[26][27] The Royals capped off the season by winning the Triple-A Classic versus the International League champion Rochester Red Wings, 4–1.

[15] The team was sold to the Union Pacific Railroad and minority investors Warren Buffett and Walter Scott for US$5 million following the 1991 season.

[29][30] The 1994 season saw outfielder Dwayne Hosey selected as league MVP and first baseman Joe Vitiello win Rookie of the Year.

[31] Though they did not qualify for the playoffs, two Royals outfielders were selected for league awards in the team's first PCL season: Chris Hatcher as the Most Valuable Player and Jeremy Giambi as Rookie of the Year.

[32] Union Pacific sold their 50-percent share in the team to Connecticut businessman Matt Minker in early 2001; Buffett and Scott retained their minority interests.

[36] As a result, the team switched back to being the Omaha Royals beginning with the 2002 season as fans cited a wish to continue with the tradition associated with the name, which had been in use from 1969 to 1998.

[39] Prior to opening Werner Park, the team rebranded as the Omaha Storm Chasers following rounds of fan submissions and voting.

[1] The Storm Chasers played their first home game at Werner Park on April 16, 2011, defeating the Nashville Sounds, 2–1, before 6,533 people in attendance.

[40] Manager Mike Jirschele led Omaha to a 79–63 record and the American Conference Northern Division title, which gave the team their first postseason berth since 1999.

[32] Jirschele's Storm Chasers returned to the playoffs in 2012 by virtue of winning the division and won a second American Conference title, but they were defeated in the championship round by the Reno Aces, 3–1.

[46] Returning to the Triple-A National Championship Game, Omaha defeated the International League's Durham Bulls, 2–1, for their first class-level title since 1990.

[47] Managed by Brian Poldberg in 2014,[48] Omaha won their fourth consecutive American Conference Northern Division title on the heels of a 76–67 season.

Bill Shea, Warren Buffett, and Walter Scott sold the team to Alliance Baseball LLC, led by managing owner Gary Green.

[57] Jackson Kowar was selected as the league's Pitcher of the Year, and shortstop Bobby Witt Jr. was chosen as its Top MLB Prospect.

[59] The Storm Chasers won the first-half of the 2024 season en route to the club's first International League championship, which they secured after defeating the Columbus Clippers in a best-of-three series, 2–1.
