Meteorological synopsis A low-pressure system formed over Nevada on November 14 and moved quickly eastward into Nebraska by the next day. It slowed down and rapidly deepened as it moved through Northwestern Iowa into Wisconsin by November 16. Favorable conditions led to a huge blow up of thunderstorms across the Mississippi and Ohio Valleys. These storms quickly became severe and tornadic as they moved generally eastward.
