A strong low pressure system to the northwest and a strong high pressure system to the southeast brought very strong south winds across central and north central South Dakota from the late morning until the early evening.  South winds of 30 to 40 mph with gusts over 60 mph caused spotty damage across the region. The high winds created large waves on Lake Oahe near Pierre which damaged several docks along with some boats at a marina.  There were also some tree branches downed across the region along with some damage to a few structures. With the high winds, warm temperatures, and low humidity several grassland fires also broke out across parts of the region. The highest wind gust of 68 mph occurred in Corson county.
