   MESOSCALE DISCUSSION 1887
   NWS STORM PREDICTION CENTER NORMAN OK
   1152 PM CDT MON OCT 13 2014

   AREAS AFFECTED...WRN FL PANHANDLE / S-CNTRL INTO CNTRL AL

   CONCERNING...TORNADO WATCH 542...543...

   VALID 140452Z - 140545Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 542...543...CONTINUES.

   SUMMARY...THE POSSIBILITY FOR LOCALIZED STRONG TO LOW-END SEVERE
   WIND GUSTS CAPABLE OF WIND DAMAGE AND PERHAPS A TORNADO OR TWO WILL
   CONTINUE INTO THE OVERNIGHT HOURS.

   DISCUSSION...RADAR MOSAIC AT 0445Z SHOWS NUMEROUS THUNDERSTORMS
   PREFERENTIALLY ALIGNED IN SEVERAL GENERALLY NORTH-TO-SOUTH ORIENTED
   BANDS.  THE KEVX VAD SHOWS PRIMARILY A STRONG SLY LOW-LEVEL WIND
   PROFILE THAT IS LARGELY UNIDIRECTIONAL WHEREAS FARTHER EAST KTLH
   EXHIBITS A LARGER LOW-LEVEL HODOGRAPH DUE TO RELATIVELY BACKED
   LOW-LEVEL FLOW.  SUFFICIENT BUOYANCY AND SHEAR FOR POTENTIAL UPDRAFT
   ROTATION WILL PERSIST THROUGH THE OVERNIGHT AS A POTENT SHORTWAVE
   TROUGH APPROACHES THE DEEP SOUTH AND INCREASING FORCING FOR ASCENT
   OVERSPREADS THE REGION TONIGHT.  HOWEVER...THE PREDOMINATE THREAT
   WILL BE DAMAGING WINDS...ESPECIALLY WITH DEEPER CONVECTIVE CORES
   THAT CAN TAKE ADVANTAGE OF WATER LOADING AND MOMENTUM TRANSPORT
   PROCESSES.
