   MESOSCALE DISCUSSION 0935
   NWS STORM PREDICTION CENTER NORMAN OK
   1010 AM CDT TUE JUN 10 2014

   AREAS AFFECTED...SOUTHEAST MS/EASTERN LA AND SOUTHWEST/WEST-CENTRAL
   AL

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 101510Z - 101615Z

   PROBABILITY OF WATCH ISSUANCE...60 PERCENT

   SUMMARY...POTENTIAL FOR AT LEAST ISOLATED DAMAGING WIND GUSTS AND
   POSSIBLY A BRIEF TORNADO SHOULD INCREASE BY LATE MORNING/MIDDAY
   MAINLY ACROSS FAR SOUTHEAST MS INTO SOUTHWEST/WEST-CENTRAL AL AND
   PERHAPS PARTS OF EASTERN LA. PENDING DEVELOPMENT TRENDS...A SEVERE
   THUNDERSTORM WATCH IS POSSIBLE FOR PARTS OF THE REGION /MOST
   PROBABLE ACROSS AL/ BY MIDDAY.

   DISCUSSION...A MODESTLY-INTENSE SQUALL LINE CONTINUES AN EASTWARD
   PROGRESSION ACROSS SOUTHERN MS AND MUCH OF SOUTHERN LA AS OF
   1445Z...WITH THE FASTEST EASTWARD PROGRESSION OCCURRING ACROSS
   SOUTH-CENTRAL MS AT AROUND 30 KT. WHILE SOME THICKER CLOUD COVER
   IMMEDIATELY PRECEDES THE SQUALL LINE...THE SQUALL-LINE PRECEDING AIR
   MASS CONTINUES TO WARM COINCIDENT WITH AMPLE LOW-LEVEL MOISTURE
   /PREVALENT LOWER 70S F SURFACE DEWPOINTS/. WITH INHIBITION ALREADY
   VIRTUALLY NIL...STORM INTENSIFICATION IS PROBABLE INTO LATE
   MORNING/EARLY AFTERNOON...PERHAPS ESPECIALLY NEAR/JUST SOUTH OF AN
   OUTFLOW-INDUCED POINT OF INFLECTION ACROSS SOUTHEAST MS INTO  AL
   WHILE SHOWERS/SOME TSTMS ALSO CONTINUE TO INCREASE AHEAD OF THE
   LINE.

   THIS POTENTIAL INTENSIFICATION WILL BE AS UPWARDS OF 2500-3000 J/KG
   MLCAPE IS INCREASINGLY REALIZED /REFERENCE 12Z OBSERVED SOUNDING
   FROM SLIDELL LA/. ALTHOUGH THE STRONGEST DEEP-LAYER WINDS WILL
   SOMEWHAT LAG THE SQUALL LINE...QUASI-LINEAR ORGANIZATION WILL BE
   AIDED BY AN INCREASINGLY STRONG BELT OF SOUTHWESTERLY MID-LEVEL
   WINDS /ESPECIALLY MS AND AL NORTHWARD/ IN ASSOCIATION WITH THE BASE
   OF THE UPSTREAM TROUGH...ASIDE FROM SOME INCREASE IN LOW-LEVEL
   WINDS.
