   MESOSCALE DISCUSSION 0339
   NWS STORM PREDICTION CENTER NORMAN OK
   0309 PM CDT SUN APR 13 2014

   AREAS AFFECTED...CNTRL/ERN OKLAHOMA

   CONCERNING...TORNADO WATCH 74...

   VALID 132009Z - 132145Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 74 CONTINUES.

   SUMMARY...RISK FOR DAMAGING WIND GUSTS WITH AN EVOLVING SQUALL LINE
   MAY INCREASE THROUGH 23-00Z...WHILE THE RISK FOR SEVERE HAIL
   CONTINUES.

   DISCUSSION...WHILE DRYLINE CONVECTION CONTINUES TO STRUGGLE...LIFT
   ALONG THE SURFACE FRONT AS IT OVERTAKES THE DRYLINE HAS BEEN
   SUFFICIENT TO FORCE VIGOROUS STORM DEVELOPMENT.  THE UPSCALE GROWTH
   OF A SQUALL LINE IS NOW WELL UNDERWAY ACROSS EASTERN KANSAS INTO
   NORTH CENTRAL OKLAHOMA...AND SOUTHWARD DEVELOPMENT IS EXPECTED TO
   CONTINUE TOWARD THE RED RIVER THROUGH 23-00Z...THOUGH THIS MAY
   MOSTLY OCCUR NORTH THROUGH EAST OF THE OKLAHOMA CITY METRO.  SEVERE
   HAIL WILL REMAIN A THREAT WITH SQUALL LINE CONVECTION...AND HEAVY
   PRECIPITATION LOADING/DOWNWARD TRANSPORT OF MOMENTUM BENEATH 30-50
   KT SOUTHERLY 850 MB FLOW ARE EXPECTED TO GRADUALLY CONTRIBUTE TO AN
   INCREASING RISK FOR SEVERE WIND GUSTS.  OTHERWISE...DISCRETE
   SUPERCELL DEVELOPMENT STILL MAY NOT BE OUT OF THE QUESTION...
   PARTICULARLY ACROSS PARTS OF SOUTH CENTRAL INTO SOUTHEASTERN
   OKLAHOMA TOWARD EARLY EVENING.
