A slow moving area of upper level low pressure over the Mid-Mississippi Valley pumped semi-tropical weather into the western Carolinas for a couple of days, resulting in occasional rounds of moderate to heavy in the day leading up to the 7th. Scattered slow-moving thunderstorm clusters developed during the morning of the 7th, producing torrential rainfall rates of 2 to 3 inches per hour and total rainfall amounts of 3 to 7 inches, much of which fell in just 2 to 3 hours. This excessive rainfall resulted in flash flooding of a number of creeks and other small streams in the Piedmont.
