Dallas (12-9) had its five-game win streak snapped.
Stewart was fouled as she hit a short jumper in the lane and missed the free throw, but Howard's offensive rebound and putback gave the Storm an 80-77 lead with 90 seconds to go. Liz Cambage answered with a layup, but was immediately called for a technical foul. Stewart hit the ensuing free throw and then Sue Bird made a 3-pointer from the left wing to push the lead to five with a minute remaining. Loyd, Alysha Clark and Stewart combined to make 7-of-8 free throws from there to seal it.
