An upper level trough moved over a moist, unstable airmass and generated thunderstorms. Storms initially formed over the higher terrain in Mexico and moved across the Rio Grande into Texas. Some storms produced damaging wind gusts. Storms eventually congealed into a slow-moving line that produce locally heavy rain leading to flash flooding.
