SATELLITE ANALYSIS AND TRENDS...FIRST VIS IMAGERY OF THE DAY SHOWS
A SMALL CLUSTER OF CONVECTIVE CELLS REMAINING NEARLY STATIONARY WITH
OVERSHOOTING TOPS AND RECENT LIGHTENING STRIKES OVER ASSUMPTION..ST
JAMES..SOUTH ASCENSION..SOUTH IBERVILLE PARISHES.  CLOUD TOP TEMPS PER IR
AT 1315Z SHOWS THAT THESE CELLS ARE WARM-TOP AT -36C..HOWEVER PW VALUES
OF 1.4-1.5 ARE SEEN IN BOTH GOES SOUNDER AND 12Z RAOB DATA OVER S LA.
THESE CELLS HAVE DEVELOPED AND REMAINED ALONG THE BEST MOISTURE TONGUE
THAT IS EVIDENT PER SFC DEW POINT AND THETA-E ANALYSES.  MANUAL STLT
ESTIMATE RAIN RATE TECHNIQUE SUGGESTS THESE CELL ARE CAPABLE OF PRODUCING
BETWEEN 1-2"/HR.  CELLS ARE EXPECTED TO EVENTUALLY MOVE VERY SLOWLY TO
THE SSE AND MAY CONTINUE TO PRODUCE HVY RAINFALL OVER PARISHES SOUTH
AND EAST OF THE DISCUSSION AREA.
