   Areas affected...a part of east TX

   Concerning...Severe potential...Watch possible 

   Valid 281446Z - 281615Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Short-line segment moving east-northeast into a part of
   east Texas may intensify as the downstream air mass slowly
   destabilizes into the afternoon. A couple brief tornadoes and
   locally damaging winds are possible.

   DISCUSSION...Remnants of the largely decaying early morning MCS have
   maintained a short-line segment within the TX Triangle. KGRK radar
   has detected transient mesovortices along its leading edge, which is
   overlapping with the western periphery of the stronger low-level
   shear environment across east TX per HGX/CRP VWP data. While surface
   wind gusts have been sub-severe thus far, primary threat will be
   potential for a couple brief tornadoes as the line segment shifts
   towards the I-45 corridor. Downstream air mass is slowly
   destabilizing amid pervasive cloud cover, but this process could
   support gradual intensification into the afternoon. 12Z CAM guidance
   differs in how extensive/intense this convection will be prior to
   later in the afternoon.
