An upper level low centered over Missouri moved slowly eastward with two lobes of vorticity that were pivoting around each other. The interaction of the two vort maxes produced two distinct areas of heavy rain, one over central/east central Missouri and another over south central and southeast Missouri. Very heavy rain fell in these areas, mainly between 3 and 4 inches of rain, though a few areas had around 6 to 7 inches of rain with this system. There were several reports of flash flooding.
