Wider weather episode

During the second/third week of June, South Texas experienced an active and dynamic weather pattern that led to several impactful weather events, including heavy rainfall, flash flooding, thunderstorm wind damage, a weak tornado, and a waterspout. The unsettled conditions were driven by a combination of deep tropical moisture, persistent upper-level disturbances, and an unstable atmosphere. PWATs frequently exceeded 2.0 inches (well above the climatological average) supporting efficient rainfall production. A series of MCSs and repeated rounds of convection produced widespread rainfall totals between 0.5-2.5 inches across much of the region, with localized amounts exceeding 9 inches, especially in the northeast Coastal Bend. These intense rainfall rates, coupled with slow-moving or training storms, resulted in significant flash flooding, prompting Flood Watches and multiple Flash Flood Warnings. The severe weather was not limited to flooding. Strong to severe thunderstorms also brought damaging winds, particularly across the Victoria Crossroads and Coastal Plains. Outflow boundaries from earlier storms helped initiate new rounds of convection, some of which strengthened rapidly in the presence of deep-layer shear and enhanced low-level inflow. This environment also proved favorable for brief, low-end tornadoes and waterspouts, with at least one weak tornado and a waterspout being reported during the active stretch.
