A strong cold front and a upper-level low pressure system combined to bring fairly widespread rainfall across the South Plains area on Monday. The welcome rain came without any severe weather and covered most of the area. As the map above shows, the far southwest Texas Panhandle was about the only area to miss out on soaking rains; receiving only about a tenth of an inch of rain across Parmer County. A band of moderate rain sat nearly motionless across eastern Yoakum and western Terry Counties much of Monday morning, and produced a swath of heavy rainfall, estimated to be nearly 7 inches south of Tokio. This cause quite a bit of flooding across draws, bar ditches and even some roads in that area.

As the upper-level storm system approached the region, a cold front raced south through the area with 30 to 40 mph northeast winds. Scattered showers developed, with activity concentrated across the southwest South Plains. The radar image below shows a northwest to southeast band of rain that set up from southern Cochran County to Dawson County. This band remained almost stationary much of Monday morning.

A National Weather Service meteorologist/hydrologist drove to the affected area to investigate the affect of the heavy rain. Signficant flooding was documented along several roadways along with some damage to roads. Bar ditches and Sulper Springs Draw were full with rapidly flowing water which was flooding into open fields.
