The episode as NWS CRP wrote it up.
A frontal boundary moved out of the Hill Country as the upper level disturbance moved into northwest Texas and western Oklahoma early on the 14th. As the frontal boundary moved into an unstable air mass over South Texas, thunderstorms developed over the Rio Grande plains west of Cotulla. The area of thunderstorms organized into another mesoscale convective system that moved east across South Texas during the early morning hours. The squall line produced widespread tree damage in the Coastal Bend. This caused power outages from Kingsville to Corpus Christi with 35 thousand customers losing power at the height of the storm. Flash flooding also occurred from Corpus Christi to Rockport.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Corpus Christi, TX wrote its last area forecast discussion before the first event at Apr 13, 11:15 PM CST, 35 minutes earlier.
