    24 Hour Rainfall Overnight Through 10 AM CDT July 28, 2010

The map above shows where the rain was heaviest, and where some locations did not receive much rain at all the evening of July 27th through the morning of July 28th. Notice that much of the area between Salem South Dakota and Harrisburg South Dakota recieved more than an inch and half of rainfall.  Some locations from central Sioux Falls through northern Lincoln county measured  more than two inches. It was also rather wet toward the northwest up to around Carthage, and toward the east to around Sanborn Iowa, where amounts were mostly between a half and nine tenths of an inch.
