A slow moving storm system translated eastward from the desert southwest across the southern Rockies and plains on the 15th and 16th. Lift and moisture associated with this system resulted in widespread showers and thunderstorms that overspread portions of the west Texas Permian Basin, South Plains, and the Panhandle early on the 15th.  Rainfall was continuous at many locations through the morning hours of the 17th.  Small scale circulations embedded within the ambient flow aloft, however, enhanced the rainfall at times and resulted in periods of heavy rain.
Daily record rainfall totals were measured at Lubbock's Preston Smith International Airport on the 15th and 16th.  The tally also set a single-rain event record for the area and jump started Lubbock toward its wettest year-to-date rainfall total in the city's history.
Doppler radar estimates indicated that the heaviest rainfall totals occurred along a swath northeast of Lubbock, over portions of Briscoe, Floyd, and Hall Counties, where upwards of eight to ten inches were estimated over rural areas.  A maximum radar estimate of nearly one foot of rain was indicated near Caprock Canyons State Park in eastern Briscoe County and western Hall County.  Ground truth measurements unofficially reached ten inches in adjacent areas of northern Floyd County, with five to seven inch totals more common.
The heavy and persistent rainfall resulted in flooding, mostly in the form of swollen playa lakes, creeks, and streams.  Some of the most significant flooding occurred along the Prairie Dog Town Fork of the Red River, where runoff from the Briscoe and Hall County rains flowed downstream over portions of Childress County.  Notable flooding also occurred along the North Double Mountain Fork of the Brazos where runoff from urban areas around Lubbock caused overflow of Buffalo Springs Lake in eastern Lubbock County.  The flow downstream cut off a number of roads and isolated several homesteads.  Structural damage was largely limited to the collapse of a flat roof on a Lubbock business that resulted in the partial collapse of the building.
At least one motorist was rescued from a stranded vehicle in Floyd County, but no injuries were reported. Total damages that resulted from the excessive rainfall and flooding across the South Plains were estimated at $475,000.
