Chased the sfc low near Vermillion, SD and watched initial promising cell grow and later succomb to weak mid flow and develop an expansive wet RFD ultimately shutting it down. The high evap cooling rates were another challenge for any convection today. This cell's outflow produced at least two organized gustnadoes alongside the HWY 3 and 12 merger near Westfield, IA. Later, another cell popped along the outflow and developed a rotating wall cloud southeast of Akron, IA. Once again, this cell began shutting down just as it began to get interesting.
