INDICATED THE SQUALL LINE THAT MOVED E/SEWD ACROSS THE MID SOUTH HAS
WEAKENED...WITH THE ATTENDANT CONVECTIVE OUTFLOW APPROACHING THE
AFOREMENTIONED BAND OF STORMS IN CENTRAL MS.  LOW-LEVEL AND DEEP
LAYER SHEAR HAS INCREASED GIVEN A 60 KT SSWLY LLJ BENEATH A 60 KT
SWLY 500 MB JET PER JAN WSR-88D VAD...WITH SFC-1 KM SHEAR EXCEEDING
