Wider weather episode

A complicated weather pattern developed over South Central Texas when a dryline and cold front moved out of West Texas as an upper level low moved into the Central Plains. At the same time the remnants of Pacific Hurricane Pamela moved across northern Mexico. The airmass over the region was warm and moist with near record precipitable water values. This set up led to an excessive rain episode with considerable flash flooding and river flooding.
