   Concerning...Severe Thunderstorm Watch 339...

   The severe weather threat for Severe Thunderstorm Watch 339
   continues.

   SUMMARY...An increasing threat for severe wind gusts and large hail
   is expected farther south in north Texas through sunrise. An
   additional severe thunderstorm watch or extension of ongoing WW 339
   is likely.

   DISCUSSION...The deepest/most intense thunderstorms within WW 339
   were centered over Clay County, TX. Recent radar evolution suggest
   this activity is beginning to pivot southeastward towards the large
   CAPE reservoir emanating north from central TX. While CAM guidance
   has been slow with the evolution of early morning convection, the
   07Z HRRR run finally appears more consistent with the 00Z NSSL-MPAS
   runs in indicating a substantial linear cluster accelerating
   southeastward across parts of the Metroplex. With deepening
   convective cores to its east, within the downstream warm-advection
   flank and the FWS VWP sampling the strongest low-level jet of the
   night (around 40 kts), this scenario appears increasingly plausible.
   Damaging gusts could reach 65-80 mph as the cold pool matures
   towards sunrise.
