MESOSCALE DISCUSSION 1070
   NWS STORM PREDICTION CENTER NORMAN OK

   AREAS AFFECTED...CNTRL MS...CNTRL AL...W-CNTRL GA
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 022206Z - 022300Z
   
   AN ISOLATED STORM OR TWO COULD PRODUCE STRONG WIND GUSTS THROUGH
   LATE THIS AFTERNOON.
   
   VERY ISOLATED PULSE CONVECTION WILL CONTINUE DEVELOPING THROUGH LATE
   THIS AFTERNOON WITHIN A ZONE OF SOMEWHAT ENHANCED DEEP-LAYER
   MOISTURE -- I.E. PWAT VALUES AROUND 1.3 INCHES PER GPS TPW DATA.
   RECENT VISIBLE SATELLITE IMAGERY DEPICTS A BROAD CUMULUS FIELD
   ACROSS THE DISCUSSION AREA...WHICH IS SUPPORTED BY A VERY UNSTABLE
   AIR MASS. A FEW ISOLATED STORMS HAVE FORMED OVER CNTRL AL AND
   W-CNTRL GA...WITH A FEW ATTEMPTS AT CONVECTION NOTED FARTHER WEST
   TOWARD THE MS RIVER. WITHOUT ANY ORGANIZED FORCING FOR ASCENT...THE
   CONVECTIVE COVERAGE WILL REMAIN VERY ISOLATED.
   
   UPON MODIFICATION TO THE 12Z JACKSON...BIRMINGHAM...AND ATLANTA AREA
   SOUNDINGS FOR CURRENT SFC OBSERVATIONS...DCAPE VALUES ACROSS THE
   REGION ARE IN EXCESS OF 1600 J/KG OWING TO VERY STEEP LOW-LEVEL
   LAPSE RATES DUE TO HOT SFC TEMPERATURES IN THE UPPER 90S TO NEAR 100
   DEGREES. THIS WILL SUPPORT THE THREAT FOR GUSTY SFC WINDS WITH ANY
   COLLAPSING CONVECTION...ESPECIALLY GIVEN TEMPERATURE-DEWPOINT
   SPREADS OF 25F TO 30F AIDING DRY AIR ENTRAINMENT PROCESSES WITHIN
   DOWNDRAFTS. A DMGG WIND GUST OR TWO CANNOT BE ENTIRELY RULED
   OUT...THOUGH THE THREAT WILL LIKELY BE VERY MINIMAL DUE TO THE
   ABSENCE OF ANY SUBSTANTIAL DEEP-LAYER SHEAR OR CONVECTIVE
   ORGANIZATION. CONVECTION WILL QUICKLY DISSIPATE WITH THE ONSET OF
   NOCTURNAL COOLING. GIVEN THESE FACTORS...A WW IS NOT NEEDED.
