Thunderstorms west of San Antonio have now formed into a small line. These storms are moving east at 20 to 25 MPH and have a history of producing hail larger than the size of baseballs in the last hour. While not indicating hail that large at the moment it is possible these storms will enter the San Antonio metro in the next hour with a threat of hail up to the size of golfballs, wind gusts over 60 MPH, very heavy rain capable of producing flash flooding, and dangerous cloud to ground lightning. Those in the S.A. Metro should take precautions now to ensure vehicles are in garages and light-weight objects outdoors are secured.
