A stationary frontal boundary draped across Central Kansas helped lead to the development of showers and thunderstorms across the region late in the afternoon of June 12th, 2010.  Abundant moisture along this frontal boundary led to the development of supercell thunderstorms with a few weak tornadoes, which mainly touched down in open fields.  The thunderstorms evolved into a line of storms and eventually led to an extended period of heavy rainfall during the overnight hours of June 12th into the early morning hours on June 13th, with some widespread flooding in Central Kansas.  The areas hit the hardest with flooding were just to the north and northeast of Hutchinson, Kansas, and to the northeast of Newton, Kansas near Peabody, Kansas.
