Cherokee's Megan Carlson made her season debut after recovering from an injury and poured in 24 points on the night, including five three-pointers to carry Cherokee to their second win of the season.
The Tornadoes were in it early, trailing just 13-10 after one quarter of play. However, Carlson and the Braves caught fire in the second, outscoring the Tornadoes 29-4 during the second quarter to claim a 42-14 halftime lead.
The continuous clock began running early in the third as the second half quickly ticked away in Storm Lake's 10th loss of the season.
After Carlson, Megan Hummel turned in 10 points for the Braves, and Kaely Hummel added seven.
The Tornadoes were led by 11 points from Brenna Richter. Chyann Smith added eight, Emily Johnson three, Kallie Croker two and Dezirae Reyes two.
The Tornadoes remain at home Monday night as they take on North Union.
