Strong winds and heavy rain accompanied a strong storm complex which moved through northeastern and east central Kansas late Sunday night into Monday morning.  Rainfall totals of between .75 and 2.00 inches were commonly reported across the area.  Isolated reports over 2 inches were also received by the National Weather Service. Flooding and flash flooding impacted the areas that received the most rain overnight.  The hardest hit areas of flooding and flash flooding were Geary, Morris, Riley, Wabaunsee, Douglas, and Lyon Counties, where multiple reports of stranded motorists and closed roads were received.
Aside from the flooding resulting from the heavy rain, strong winds did damage to portions of Topeka, Kansas near midnight.   A storm damage survey concluded that tree damage was the result of strong straight line winds, estimated between 70 and 85 mph, which pushed through the area overnight.  Large trees were snapped or uprooted by the winds, and fell on nearby structures and vehicles.  A wind gust of 83 mph was measured just south of downtown Topeka near 21st Avenue and Kansas Avenue.
