SATELLITE ANALYSIS AND TRENDS...VISIBLE LOOP SHOWS PULSING CONVECTION
DEVELOPING SW ALONG SEA BREEZE BOUNDARY ACROSS NW JEFFERSON INTO E
CHAMBERS COUNTY.  WEAK SFC FLOW IS LEADING TO LIMITED MOVEMENT OF THE
CONVECTION AS WELL.  TOPS ARE QUITE WARM ON IR BUT WITH STATIONARY
UPWIND DEVELOPMENT OF THE LINE...IR TECHNIQUES WOULD SUPPORT 1.5"/HR
RATES WITHIN A PW ENVIRONMENT OF 1.8 TO 2.0" PER SOUNDER AND GPS NETWORK.
3HR TOTALS NEAR 4" HAVE BEEN ESTIMATED MANUALLY ACROSS NE CHAMBERS.

VIS IMAGERY ALSO SHOWS ENHANCED LL CONVERGENCE OF THE FEEDER CU BANDS
INTO THE CHAMBERS COUNTY CELL AS SEEN BY SLOW NELY MOTION OF CU ON THE
SEA BREEZE ALONG WITH OUTFLOW BOUNDARY FROM CONVECTION ACROSS HARDIN
COUNTY MOVING W AND S.  ADDITIONALLY, AN OUTFLOW BOUNDARY FROM DISSIPATED
CONVECTION TO THE EAST IS PROGRESSING WEST TOWARD THE TX LINE.  ALL THESE
FACTORS COULD LEAD TO A SHORT DURATION INCREASE OF CONVECTION BUT ALSO
SHIFT CONVECTION SWLY ALONG THE BOUNDARY AND WEAKENING ONGOING CONVECTION
FOR SHORTER DURATION HVY RAINFALL AND DECREASED FLOODING THREAT.
