   The severe weather threat for Severe Thunderstorm Watch 64

   SUMMARY...Isolated strong to severe storms will continue across
   portions of western north Texas into the Rio Grande region this
   evening. Uncertainty exists with regards to additional storm
   development and Severe Thunderstorm Watch 64 continues across the

   DISCUSSION...Some uncertainty continues with regards to additional
   convective development into the nighttime hours across parts of
   western TX. A line of storms that developed early ahead of the
   dryline will continue to lift east/northeast across north TX while
   isolated cells persist further south toward the Big Bend vicinity.
   Hi-res HRRR guidance continues to insist additional development will
   occur along the retreating dryline. Additionally, guidance continues
   to indicate that storms developing across the Rio Grande in Mexico
   will lift northeast overnight into parts of west TX. A lack of more
   robust storm development along the Sierra del Burro and some modest
   growth of cumulus along the dryline call this scenario into
   question. Given uncertainty, and an environment that will continue
   to support severe storms should they develop, Severe Thunderstorm
   Watch 64 continues.
