   MESOSCALE DISCUSSION 0774
   NWS STORM PREDICTION CENTER NORMAN OK
   0657 PM CDT MON MAY 25 2015

   AREAS AFFECTED...SOUTHERN MO

   CONCERNING...SEVERE POTENTIAL...WATCH LIKELY 

   VALID 252357Z - 260130Z

   PROBABILITY OF WATCH ISSUANCE...80 PERCENT

   SUMMARY...A WATCH IS LIKELY THIS EVENING FOR PORTIONS OF SOUTHERN MO
   FOR AN INCREASING RISK OF WIND DAMAGE AND A COUPLE OF TORNADOES.

   DISCUSSION...THE NORTHERN/COMMAHEAD PORTION OF A SQUALL LINE SHOULD
   STEADILY APPROACH PORTIONS OF SOUTHERN MO FROM THE SOUTHWEST THROUGH
   THE EVENING HOURS...WITH AN INCREASING CONCERN FOR WIND DAMAGE AND
   SOME TORNADO RISK. ADDITIONALLY...A FEW SEMI-DISCRETE SUPERCELLS
   CAPABLE OF A TORNADO RISK COULD DEVELOP NORTHWARD INTO AT LEAST FAR
   SOUTHERN MO AHEAD OF THE BROADER CONVECTIVE LINE. THE PRECEDING AIR
   MASS FROM NORTHERN AR INTO SOUTHERN MO REMAINS WARM...WITH SOME
   UPPER 60S F SURFACE DEWPOINTS EXTENDING NORTHWARD INTO SOUTHERN MO.
   THIS RELATIVELY FAVORABLE THERMODYNAMIC ENVIRONMENT...COUPLED WITH
   THE WELL ORGANIZED NATURE OF THE SQUALL LINE /INCREASING REAR INFLOW
   ETC./ AND AN ADDITIONAL STRENGTHENING OF SOUTH-SOUTHWESTERLY
   LOW/MID-TROPOSPHERIC WINDS THIS EVENING...SUGGESTS THAT AT LEAST
   SOME WIND DAMAGE/TORNADO THREAT SHOULD DEVELOP INTO SOUTHERN MO THIS
   EVENING.
