   Concerning...Severe Thunderstorm Watch 224...

   Valid 160250Z - 160415Z

   The severe weather threat for Severe Thunderstorm Watch 224
   continues.

   SUMMARY...Hail and one or more swaths of severe wind gusts may
   accompany an intense thunderstorm cluster as it moves southward
   across north Texas. Southward expansion of WW 224 may be needed.

   DISCUSSION...An intense supercell cluster is moving into north TX at
   0245Z. Strong buoyancy (MLCAPE > 3000 J/kg) and sufficient effective
   shear (30-40 kt) (noted on the 00Z FWD sounding and recent objective
   mesoanalyses), combined with an increasing southerly low-level jet
   noted on the KFWS VWP, will continue to support this cluster as it
   moves southward, though increasing MLCINH should eventually lead to
   a weakening trend later tonight. 

   Large hail remains possible with the stronger embedded cells.
   However, some southward acceleration of the cluster has been noted
   in the last hour, potentially indicative of a strengthening cold
   pool, and wind gusts to 70 mph were noted across southern OK with
   the passage of this cluster. One or more swaths of severe wind gusts
   will be possible as this cluster spreads southward, potentially
   reaching the Metroplex by 0330-0400Z. Southward expansion of the
   watch may be required within the next hour.
