Thunderstorms developed along an outflow boundary in a very moist airmass. Storms were fed by strong low level winds. In addition to aiding buoyancy, these winds also contributed to significant low level wind shear. Some storms produced weak tornadoes and locally heavy rain that led to flash flooding.

Some noticeable minor damage was observed on Blue Sage Ln., and a tree was knocked down on Cinnabar Trail.  The weak tornado moved northeast but did not appear to be on the ground for its entire track. There was some shingle damage to several homes in the Saratoga neighborhood. Video confirmed that the tornado likely crossed Dean Rd. (CR 377) and dissipated shortly thereafter. Times were estimated from radar and time stamps from resident videos. The tornado path was 2 miles long but there were many sections of the path where there was no visible damage.  Maximum winds were estimated at 65 mph.

A National Weather Service damage survey concluded that a small EF0 tornado occurred north-northwest of Stockdale during the early morning hours of October 26th. The tornado touched down approximately three miles north-northwest of Stockdale, near CR 422, producing a narrow path of tree damage. The tornado continued north, remaining disorganized and producing sporadic tree damage. At times the path was hard to determine between CR 334 and CR 434, and the tornado may have lifted off the ground at times. Along Longhorn Rd. the tornado produced damage to a patio awning of a residence, tore tin roofs off sheds and pens, and produced additional tree damage. The tornado dissipated just north of Longhorn Road. The tornado path length was 5.99 miles, and maximum wind speeds were estimated were estimated at 75 mph.

A National Weather Service damage survey concluded an EF-0 tornado started near the south end of the Masonic Cemetery off of E. Commerce St. in San Antonio. Several trees were damaged in the cemetery between E. Commerce and E. Crockett St., and a fence was damaged at the tennis courts in Fairchild Park. As the track headed north-northeast, there was sporadic, very minor tree damage in the neighborhood, and a couple metal roof panels were lifted off an old structure in the railyard just west of N. New Braunfels Ave. The damage path was more notable within Ft. Sam Houston. Several trampolines were lofted, part of the roof was damaged on a building near the south end of the Fort, and significant tree damage was observed throughout the Fort property up to near Old Austin Rd. After that point, damage was again more sporadic and the tornado may have briefly lifted through much of Terrell Hills until reaching the Alcove Apartments on N. Vandiver Rd. Roof damage was noted to the northern building there, as well as damage to the Southwest Preparatory school across Seidel Rd. Security camera footage showed a small circulation crossing at Austin Hwy and N. Vandiver Rd. at 7:18 am, and though it is possible that additional sporadic damage occurred northeast of here, the survey team was unable to find any notable damage north of Austin Hwy. The path length was 5.17 miles, and maximum winds were estimated at 80 mph.
