   MESOSCALE DISCUSSION 1935
   NWS STORM PREDICTION CENTER NORMAN OK
   0531 PM CST SAT NOV 22 2014

   AREAS AFFECTED...PORTIONS OF THE RIO GRANDE VALLEY AND DEEP SOUTH TX

   CONCERNING...SEVERE THUNDERSTORM WATCH 557...

   VALID 222331Z - 230030Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 557
   CONTINUES.

   SUMMARY...THE LARGE HAIL AND DAMAGING WIND THREAT WILL PERSIST
   ACROSS WATCH 557 THE NEXT FEW HOURS. STORMS WILL CONTINUE TO TRACK
   EASTWARD AROUND 40-50 MPH TOWARD THE I-10 AND I-37 CORRIDOR. TRENDS
   WILL BE MONITORED FOR POTENTIAL DOWNSTREAM WATCH ISSUANCE LATER THIS
   EVENING.

   DISCUSSION...ENVIRONMENTAL PARAMETERS WILL CONTINUE TO SUPPORT A
   THREAT FOR LARGE HAIL AND STRONG WIND GUSTS ACROSS THE WATCH AREA.
   WHILE DEEP LAYER SHEAR IS MARGINAL...STEEP MID LEVEL LAPSE RATES
   COMBINED WITH MODERATE INSTABILITY WILL ALLOW FOR VIGOROUS UPDRAFTS
   AND THE GENERATION OF LARGE HAIL...SOME POSSIBLY AS LARGE AS
   BASEBALL SIZE. ADDITIONALLY...STEEP LOW LEVEL LAPSE RATES AND FAST
   STORM MOTION OF AROUND 40-50 KTS TOWARD THE EAST COULD ALLOW FOR
   STRONG/DAMAGING WIND GUSTS. TRENDS WILL CONTINUE TO BE MONITORED FOR
   POTENTIAL DOWNSTREAM WATCH ISSUANCE LATER THIS EVENING.
