   0835 PM CDT Sat Mar 17 2018

   Areas affected...east central Texas

   Concerning...Severe Thunderstorm Watch 9...

   Valid 180135Z - 180230Z

   The severe weather threat for Severe Thunderstorm Watch 9 continues.

   SUMMARY...Isolated damaging wind and large hail remain possible over
   east central Texas through 04Z, but overall trend should be for
   storms to weaken after 03Z.

   DISCUSSION...As of mid evening, storms persist over the eastern part
   of central TX from east of Kileen to west of Lufkin. The strongest
   storms are developing along an outflow boundary interacting with a
   modest southerly low-level jet. A couple of supercell structures
   continue to be observed with large hail the main threat. With onset
   of nocturnal cooling, updrafts should become increasingly elevated
   with a gradual weakening trend expected during the next couple of
   hours.
