A supercell thunderstorm is moving along I-35 in the general direction of the southwest part of the San Antonio Metro area. Based on its present movement, the storm will impact the Devine, Natalia and Lytle areas between 7:30 and 8pm. If the storm continues moving Northeast from that point, it would impact the southwest side of San Antonio between 8 and 8:30 pm.
Hail and very heavy rainfall may also affect the La Coste and Castroville areas in association with this storm, especially toward 8pm CDT.
Severe storms of this type sometimes tend to change their movement from time to time. So, if you live along or either side of the axis outlined above (as shown by the red outlined area on the radar image), keep a close eye on this storm.
This storm has a history of producing golfball sized hail and has also shown signs of rotation at times. A tornado is certainly possible with this storm, in addition to a threat of potentially damaging wind gusts. Very heavy rainfall and dangerous lightning can also be expected.
If you live in the path of this storm, seek immediate shelter until threatening weather passes.
