A wave of low pressure moved along a nearly stalled front late on the 6th, with an upper level shortwave trough moving over head. The combination of these features produced a band of heavy, persistent rainfall. One to two inches of rain fell in 6-12 hours. With saturated ground in place from previous rain, this led to flooding of small creeks, streams and rivers.
