A nearly-stationary upper-level low positioned over western Texas created an environment conducive to three distinct severe weather episodes over eastern Texas. Monday morning's (3/12) fast-moving squall line was initiated from a shortwave rounding the base of the upper low. Tuesday's (3/13) scattered convection was a second shortwave riding up from the west southwest around the still quasi-stationary upper low. Wednesday's (3/14) events stemmed from the upper-low moving eastward over the region into Louisiana.
