Erin, the fifth named storm of the 2007 Atlantic Hurricane Season, made landfall in the morning hours of Thursday, August 16th, close to Corpus Christi, Texas. The low pressure system then pushed gradually northwest over the Edwards Plateau region of South-Central Texas through Friday Night, before curving back to the northeast over the West Texas Plains on Saturday.

On Saturday Afternoon, August 18th, the low pressure system was approaching the National Weather Service Norman's County Warning Area. By 10 PM local time on Saturday, the low had entered Southwest Oklahoma near Altus. It proceeded to track northeastward over Southwest and Central Oklahoma, eventually pushing east of the Oklahoma City metropolitan area by around noon Sunday. However, during the overnight hours Saturday, the low pressure system deepened as it tracked over the western two-thirds of Oklahoma, and thus produced a variety of hazardous weather.
