A second mesoscale convective system in as many nights developed across southeast South Dakota and southwest Minnesota in the late afternoon and early evening in response to a weak mid-level wave and warm advection over a stalled frontal boundary to the south. Rainfall rates up to 2 to 3 inches per hour on top of previously saturated soil resulted in local flash flooding.
