A surface front, initially across northern Missouri, moved slowly southward as an upper level low over the southern Rockies made its way eastward into the Central Plains.  The surface front became stationary as it approached the Missouri-Arkansas border.  A very moist and unstable air mass south of the front set off several rounds of severe weather.  One tornado touched down northwest of Neosho in Newton county during the overnight hours on Wednesday and several reports of strong winds and hail up to the size of golf balls were received from mid-morning into the late evening hours on Thursday.

Once the front became stationary during the day on Thursday, several waves of moderate to heavy rainfall made their way along the front.  This produced a band of 1 to 2+ inch rainfall along and just north of the front.
