Tornado Watch for Austin-San Antonio corridor until 6am Saturday

Thunderstorms are developing rapidly North of the Big Bend into west-central Texas now that intense upper level energy is moving deeper into the area (see last blog post for satellite image).  San Antonio is located at the right-most center part of the image below, taken at 9:59pm from the Laughlin AFB radar:

For the next 2 hours, the greatest threats will be increasingly large hail and gusty straight-line winds.  Toward and after Midnight, as the activity moves toward the I-35 corridor, conditions will become more supportive for possible rotation and tornado development.

Please stay alert as this potentially dangerous situation is made worse by the fact that it will reach the more populated areas well after most folks head off to bed.
