An upper level closed low, an upper level disturbance, and low level moisture all converged over southeastern New Mexico and west Texas.  All of this led to a Mesoscale Convective System that moved over the area dumping one to three inches of rain and resulting in massive flash flooding in Ector County.  While the main threat, and most of the resulting damage was due to flash flooding, moderate to strong instability existed across the area and produced up to softball size hail.

Widespread flooding occurred in Odessa on Wednesday morning including damage to at least 100 homes.  The number of homes affected, vehicles stranded in high water, and several county buildings damaged by flooding prompted the Ector County Judge to declare a state of emergency in the county the following day.
Damage to homes ranged from minimal wind and rain damage to up to two feet of water inside homes. Several vehicles were stranded in anywhere from two to four feet of water.  Eleven inches of water pooled in the basement of the Ector County Library while two to three inches was found in the Ector County Health Department. On the following day, newspapers reported that 25 to 40 families sought assistance from the American Red Cross.  Ector County Road, Bridge, and Traffic Department employees worked overtime pumping water out of flooded streets on subsequent days.
During the storm, high schools closed their campuses to off campus travel, prompting a need for food to be delivered to the campuses to feed all the students who normally travel off campus for lunch.  Odessa firefighters and EMS personnel responded to 95 calls for high water rescues during these storms.
