   The severe weather threat for Severe Thunderstorm Watch 358

   SUMMARY...The strong wind threat attendant to a QLCS may increase as
   it spreads east-southeast in central Texas. A brief tornado is also

   DISCUSSION...A QLCS extending from Comanche to Concho County should
   continue to progress east-southeast across the Colorado River Valley
   of central TX. The northeast portion of the line has surged faster
   than the southwest portion, but is mainly crossing over the
   relatively cooler surface conditions north of prior convective
   outflow that extends from McCulloch County to the greater Austin
   area. Still, a gust to 44 kt was measured at the Brownwood AWOS.
   Farther south, closer to the remnant outflow boundary, a couple
   attempts at broader mesovortex formation have occurred within the
   enhanced low-level SRH environment. Additional attempts may yield
   corridors of enhanced severe wind gusts and potentially brief
   tornadogenesis as the QLCS impinges on the relatively warmer/more
   moist boundary-layer near/west of Austin.
