   CONCERNING...SEVERE THUNDERSTORM WATCH 50...
   
   VALID 142237Z - 150000Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 50
   CONTINUES.
   
   HOWEVER...THE THREAT APPEARS TO BE GRADUALLY DIMINISHING...AND A NEW
   WW IS NOT ANTICIPATED.
   
   A PRE-COLD FRONTAL SQUALL LINE CONTINUES TO ADVANCE EASTWARD ACROSS
   NORTHERN/CENTRAL ALABAMA AND SOUTHEAST MISSISSIPPI AT AROUND 30
   KT...AND WILL CLEAR THE REMAINDER OF THE WATCH WITHIN THE NEXT HOUR
   OR SO.  TO THIS POINT...IT APPEARS THAT THE SEVERE THREAT HAS BEEN
   LIMITED WITH THIS ACTIVITY...AND THERE SEEMS LITTLE TO SUGGEST
   SIGNIFICANT FURTHER INTENSIFICATION WILL OCCUR.  MOISTURE CONTENT
   WITHIN THE EASTERLY LOW-LEVEL INFLOW LAYER DECREASES WITH EASTWARD
   EXTENT ACROSS THE EASTERN GULF STATES.  AND...THE GENERAL MODEST
   NATURE OF THE WIND FIELDS AND SHEAR WITHIN THE WARM SECTOR OF THE
   SURFACE LOW MIGRATING INTO THE TENNESSEE VALLEY PROBABLY IS LIMITING
   THE STRENGTH OF THE CONVERGENCE ALONG THE SQUALL LINE GUST FRONT.
   
   THERE IS SOME INDICATION THAT FORCING ASSOCIATED WITH A MID-LEVEL
   SPEED MAXIMUM NOSING ACROSS NORTH CENTRAL ALABAMA TOWARD THE
   SOUTHERN APPALACHIANS...IN ADVANCE OF THE UPPER CLOSED LOW NOW
   BEGINNING TO TURN EAST OF THE OZARK PLATEAU...COULD AT LEAST
   MAINTAIN THUNDERSTORM ACTIVITY ACROSS NORTHEAST/EAST CENTRAL ALABAMA
   INTO THE ATLANTA METRO AREA BETWEEN NOW AND 01-02Z.  WHILE GUSTY
   WINDS MAY CONTINUE TO ACCOMPANY THIS ACTIVITY...IT SEEMS PROBABLE
   THAT PEAK SPEEDS WILL GENERALLY REMAIN BELOW 50 KTS.
