A rather active pattern continues to bring heavy rainfall across the lower Missouri River Valley this week.  Heavy rainfall began in the region during the overnight hours of August 16th and once again during the morning of the 17th.  This heavy rainfall was due in part to a multi-part process, including a large plume of sub-tropical moisture streaming into the region and the collision of this air mass with a weak stationary front driving southward into the region.  

The end result was widespread 2 to 4 inch rainfall amounts in much of the region.   Even higher rainfall totals were reported in locations from Platte City, MO to Cameron, MO, Gallatin, Chillicothe, Brunswick, Kirksville and Macon where as much as 6 to 10 inches of rainfall had fallen.  At Kansas City International, a 2 day total of 4.81 inches from the 16-18th was the 7th highest 2-day rainfall total for the month of August.  

Below,  you will find a map depicting the radar estimated totals across the Pleasant Hill forecast area.  In addition, a text listing of some of the highest rainfall totals can be found below the image.
