The National Weather Service has issued a tornado watch until 6 a.m. for several South Texas counties including parts of Bandera, Edwards, Gillespie, Kerr, Kimble, Kinney, Mason, Medina, Real, Sutton, Uvalde, and Val Verde.
NWS says that the storm will make it's way across South Texas slowly, concentrating out west in Val Verde, Edwards, Kinney, Uvalde, Real, and Kerr County areas until 3 a.m. and then working it's way toward Bexar County and the San Antonio area.
The main threats are tornadoes, large hail, high winds, and heavy rainfall.
We'll be watching for any flooding as the rain from Saturday combined with the slow movement of the storm sets up flooding chances in the areas in which the storm will hit.
Earlier this year, San Antonio and the surrounding areas saw several tornadoes touch down, including in the city. Amazingly, nobody was reported injured.
