   MESOSCALE DISCUSSION 0185
   NWS STORM PREDICTION CENTER NORMAN OK
   0528 PM CDT SAT MAR 15 2014

   AREAS AFFECTED...CNTRL TX

   CONCERNING...SEVERE THUNDERSTORM WATCH 29...

   VALID 152228Z - 160000Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 29
   CONTINUES.

   SUMMARY...SEVERE WEATHER POTENTIAL CONTINUES...AND COULD STILL
   INCREASE WITH UPSCALE CONVECTIVE GROWTH POSSIBLE INTO THE INTERSTATE
   35 CORRIDOR OF CENTRAL TEXAS THROUGH 00-02Z.  COUNTIES TO THE SOUTH
   OF WW 0029 IN THE FWD CWA MAY NEED TO BE ADDED TO WW 0029.

   DISCUSSION...STRONGEST STORM DEVELOPMENT HAS BEEN FOCUSED WELL TO
   THE WEST AND SOUTHWEST OF THE DALLAS/FORT WORTH METROPLEX...ACROSS
   AND EAST OF THE ABILENE AREA.  THIS IS WHERE THE MOST SUBSTANTIVE
   BOUNDARY LAYER DESTABILIZATION HAS TAKEN PLACE...WITHIN A ZONE OF
   DIFFERENTIAL SURFACE HEATING ON THE SOUTHWESTERN PERIPHERY OF MORE
   EXTENSIVE CONVECTIVE CLOUD COVER AND PRECIPITATION...WHERE IT IS
   INTERSECTED BY THE DRYLINE.  

   MID-LEVEL FORCING FOR UPWARD VERTICAL MOTION AHEAD OF A CYCLONIC
   VORTICITY CENTER ASSOCIATED WITH AN INITIAL SHORT WAVE TROUGH
   LIFTING NORTHEASTWARD OUT OF THE TEXAS SOUTH PLAINS HAS AIDED
   DEVELOPMENT.  AND THIS COULD STILL SUPPORT UPSCALE CONVECTIVE GROWTH
   ALONG THE ZONE OF DIFFERENTIAL HEATING/EFFECTIVE WARM FRONT ACROSS
   CENTRAL TEXAS THROUGH THE 00-02Z TIME FRAME.  

   IT IS POSSIBLE THAT THIS COULD EVENTUALLY IMPACT AT LEAST SOUTHERN
   PORTIONS OF THE METROPLEX...AND SEVERE WEATHER POTENTIAL MAY NOT BE
   COMPLETELY NEGLIGIBLE WITH STORMS NOW SPREADING ACROSS THE
   METROPLEX...BUT THE HIGHEST SEVERE WEATHER PROBABILITIES NOW APPEAR
   SOUTHEAST OF ABILENE INTO THE I-35 CORRIDOR BETWEEN AUSTIN AND THE
   METROPLEX.
