Flash Flood — Apr 23, 2025
A small cluster of thunderstorms developed in deep southerly flow and a warm, moist airmass behind a warm front. There were steep mid-level lapse rates in this airmass, and these storms produced large hail.
Flood — Jul 15, 2025
A mesoscale convective vortex developed over northern Mexico and sent an outflow boundary into South-Central Texas. Thunderstorms in this complex produced locally heavy rain that led to flash flooding.
