What happened

The episode as NWS EWX wrote it up.

Along the edge of the Hill Country, rainfall began in the early morning hours, and by 0500 to 0600 CST, average accumulations were in the 2 to 3 inch range and still increasing. By sunrise, totals were up to 4 inches in many locations, with heavy rain continuing into the mid-morning. Widespread flash flooding developed very close to sunrise and continued into the late morning and early afternoon over the area. Nearly all rural roads in Kendall and Gillespie Counties were closed, as well as in southern Burnet County. Flash flooding was widespread in Bexar County, mainly in poorly drained areas and along rural roads. Damage was generally to roads and bridges across the area.
