Severe Storms, Flooding Rainfall Likely Austin-San Antonio Area After Midnight...

The above radar shows a line of strong to severe storms extending from Southeast of Del Rio to Kerrville and Fredericksburg to West of Georgetown.  The line is moving slowly Eastward, while storms within the line are moving North/Northeast at 25 mph.

Hail up to golfball size and wind gusts of 60-70 mph have been reported fairly consistently with this activity for the past 1-2 hours.  Torrential rain is also falling in association with this activity, at the rate of 2-3 inches per hour at times.  This will lead to flash flooding, as well as flooding of small streams and low lying areas.

Based on the present rate of movement, the threat of severe weather will enter the Austin/Kyle/Buda area along I-35 after Midnight, most likely toward 1am or so.  The threat of severe weather will likely spread into the San Antonio Metro area shortly thereafter.

Once storms begin, they will last awhile, potentially several hours, which will further aggravate the threat of flooding.  The highest severe weather potential will take place during the first 90 minutes that the activity begins in a given location.  Large hail, damaging wind gusts and even a tornado cannot be ruled out with this activity overnight and during the pre-dawn hours Tuesday.

If you live in this region, prepare your sheltering area before turning in for the night, that way you can quickly access it if need be.  Make sure that you have a way to receive severe weather warnings overnight as well.
