Observation from ktxporta226 Harvey.
The wider storm
The large-scale weather pattern featured a split flow with a southern jet stream stretching from northern Mexico into the Gulf States. A weak upper-level disturbance, near the Baja Peninsula, moved into the Big Bend region by evening. Ahead of this feature, southeasterly winds helped push deeper moisture into far West Texas, aided by earlier storms. With strong surface heating in place west of this moisture, isolated thunderstorms developed by late afternoon across higher terrain in West Texas and northeastern Mexico. Later in the night, a strengthening low-level jet organized some of these storms into larger clusters, leading to elevated winds.
Began near Port Aransas (27.8700, -97.0800).
