DISCUSSION:

RECENT ANIMATED MULTISPECTRAL IMAGERY SHOWS GOOD MID-LEVEL TURNING AND CONVECTIVE DEVELOPMENT OVER A BROAD AND ILL-DEFINED LOW-LEVEL CIRCULATION CENTER. UPPER LEVEL ANALYSIS INDICATES THAT THE SYSTEM IS UNDER THE SUBTROPICAL RIDGE AXIS AND IN AN AREA OF FAVORABLY LOW VERTICAL WIND SHEAR (LESS THAN 10 KNOTS).HOWEVER, AN UPPER LEVEL TROUGH IS APPROACHING THE SYSTEM FROM THE NORTHWEST AND IS HINDERING OUTFLOW AND BRINGING COOLER, DRIER AIR.
