Rainfall Totals
Southerly winds just above the surface ushered copious amounts of moisture from the Gulf of Mexico over a nearly stationary frontal boundary across Central Texas. This moisture, combined with a few upper level disturbance ahead of the main trough across the Western United States, resulted in nearly continuous rainfall with a few thunderstorms from Friday night through Sunday mainly along and north of Interstate 20. The heaviest rainfall was along the Interstate 30 corridor.

The upper trough pushed east into the Southern Plains Sunday night and Monday. This allowed the frontal boundary to push a bit farther north as a warm front into East Texas and Central Louisiana. This brought another round of heavy rainfall and thunderstorms across the region. Finally, the rain came to an end Monday evening, March 20th, 2006.
