   LATEST WV IMAGERY SUGGESTS A WEAK UPPER VORT MAY BE EMBEDDED WITHIN
   THE BASE OF THE LARGER TROUGH OVER SERN MS.  THIS FEATURE IS
   SHIFTING EAST TOWARD SRN AL/FL PANHANDLE AND APPEARS TO BE AIDING
   ONGOING CONVECTION THAT HAS GRADUALLY INTENSIFIED OVER THE LAST
   HOUR.  RADAR DATA SUGGEST THIS ACTIVITY IS MOVING EAST AT ROUGHLY
   35KT AND IS SLOWLY TAKING ON CHARACTERISTICS OF A LINEAR MCS.  GIVEN
   THE PROGRESSIVE NATURE OF THE UPPER TROUGH LATEST THINKING IS
   ONGOING TSTMS WILL MIGRATE ACROSS SRN AL INTO THE FL PANHANDLE AND
   PERHAPS EVEN SWRN GA BY 21Z.  DAMAGING WINDS MAY BE NOTED WITH THIS
   CONVECTION AND A SEVERE TSTM WATCH IS BEING CONSIDERED.
