A closed upper level low across West Texas and Eastern New Mexico moved slowly east into West-Central Texas on the 13th.  A short-wave trough in the base of the low tracked north-eastward across the Rio Grande Plains into the Coastal Plains of South Texas during the evening hours.  Large scale lift ahead of this feature spread across portions of Souh Texas during the afternoon, atop airmass that was moist and unstable.  Sufficient deep layer shear resulted in isolated severe storms during the afternoon across South Texas.  Evetually an organized MCS developed and swept across South Texas during the evening hours.  Southwesterly mid level winds of 40-50 kts atop a strenghtening low level jet in the evening across South Texas resulted in both bowing line segments and supercells.
