Here are rainfalls across Sedgwick County, Kansas, this morning. You can see that amounts vary greatly over just a few miles. Below is the radar from yesterday evening as torrential rains moved in. The storm developed over this area (meaning it dropped no rain farther northwest).

The area of thunderstorms responsible for the heavy rain was moving from northwest to southeast and never dropped any rain over areas to the west. So, the official National Weather Service rain gauge had just 0.01 inches while far northeast Wichita had 2.05 inches.
