Severe thunderstorms...producing downburst winds...developed during the afternoon hours of August 20th on the eastern edge of an upper level ridge of high pressure centered across Central Texas. A weak surface trough lingered across the area and storms often initiated near this boundary. Migrating outflow boundaries from the initial storms would ignite more convective activity as they moved throughout the area. Most of the severe thunderstorm activity were pulse in nature and produced localized downbursts. Surface temps across the area were over the century mark the afternoon of the 20th so it did not take much convection to get wind damage.
