MESOSCALE DISCUSSION 1081
   NWS STORM PREDICTION CENTER NORMAN OK
   1233 PM CDT SUN JUN 10 2007
   
   AREAS AFFECTED...SRN MO AND NRN AR
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 101733Z - 101830Z
   
   ...ISOLATED WIND/HAIL THREAT MAY DEVELOP DURING THE NEXT FEW HOURS
   ...BUT WW NOT ANTICIPATED DUE TO EXPECTED SPARSE SEVERE COVERAGE IN
   MO AND THE PULSE NATURE OF THE STORMS IN NRN AR.
   
   AT 1720Z...A SQUALL LINE EXTENDED FROM 20W FAM TO 20 W UNO... MOVING
   ESEWD AT 30 KT DUE TO A WELL DEVELOPED COLD POOL. HOWEVER ...STORMS
   ARE MOVING INTO A PROGRESSIVELY MORE UNSTABLE ENVIRONMENT WITH
   CONSIDERABLE MID/HIGH CLOUDS. THE STRENGTH OF THE COLD POOL MAY
   RESULT IN ISOLATED STRONG/SEVERE WIND GUSTS ALONG THE LINE AS IT
   MOVES THROUGH SERN MO THIS AFTERNOON...BUT WEAK INSTABILITY SHOULD
   LIMIT THE SEVERE THREAT.
   
   ACROSS NWRN AR AND EXTREME SWRN MO...SCATTERED CONVECTION HAS
   RECENTLY DEVELOPED WITHIN A VERY MOIST AND UNSTABLE AIR MASS...WITH
   MLCAPES BETWEEN 3000 AND 4000 J/KG. GIVEN THE WEAKLY CAPPED
   ENVIRONMENT AND CONVERGENCE ALONG AN OUTFLOW BOUNDARY FROM MO
   CONVECTION...STORMS ARE EXPECTED TO BECOME MORE NUMEROUS THROUGH THE
   AFTERNOON. THOUGH THE DEGREE OF INSTABILITY WOULD CERTAINLY SUPPORT
   A THREAT FOR MARGINALLY SEVERE HAIL/WINDS...THE WEAK DEEP LAYER
   SHEAR SUGGESTS ANY SEVERE SHOULD BE THE PULSE TYPE VARIETY.
