.Showers and thunderstorms will impact extreme southeast Kansas and 
the Missouri Ozarks today through tonight. Rainfall amounts are 
expected to range from three quarters of an inch to two inches in 
widespread fashion. Due to elevated streamflows, wet soil 
conditions, and the lack of vegetation, runoff will be efficient and 
likely lead to flash flooding.
