   MESOSCALE DISCUSSION 0378
   NWS STORM PREDICTION CENTER NORMAN OK
   0713 PM CDT MON APR 21 2014

   AREAS AFFECTED...PARTS OF CNTRL AND S CNTRL TEXAS

   CONCERNING...SEVERE THUNDERSTORM WATCH 85...

   VALID 220013Z - 220145Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 85
   CONTINUES.

   SUMMARY...SEVERE HAIL THREAT WILL CONTINUE WITH DRYLINE STORMS INTO
   THE 01-03Z TIME FRAME...WHILE POTENTIAL EXISTS FOR A SMALL ...BUT
   INCREASINGLY ORGANIZED MESOSCALE CONVECTIVE SYSTEM TO APPROACH SAN
   ANTONIO WITH THE RISK FOR DAMAGING WIND GUSTS.

   DISCUSSION...STRONG/SEVERE STORM DEVELOPMENT REMAINS GENERALLY
   FOCUSED ALONG THE DRYLINE...WITH STRONGEST ACTIVITY ACROSS SOUTH
   CENTRAL TEXAS IN ASSOCIATION WITH RECENT STORM MERGER EAST OF
   JUNCTION.  GIVEN MODEST SOUTHEASTERLY SYSTEM RELATIVELY
   INFLOW...THIS ACTIVITY APPEARS LIKELY TO CONTINUE PROPAGATING
   SOUTHWARD...AND COULD IMPACT THE SAN ANTONIO METRO AREA BY 02-03Z. 
   PERHAPS AIDED BY WEAK LOW-LEVEL WARM ADVECTION AND INFLOW OF
   UNSTABLE AIR CHARACTERIZED BY MIXED LAYER CAPE ON THE ORDER OF 2000
   J/KG...FURTHER INTENSIFICATION AND UPSCALE GROWTH APPEARS POSSIBLE
   BEFORE REACHING SAN ANTONIO.  AS THIS OCCURS...THE RISK FOR SEVERE
   HAIL WILL CONTINUE...AND THE RISK FOR A DAMAGING DOWNBURST
   ACCOMPANIED BY STRONG SURFACE GUSTS MAY BE INCREASING.
