SATELLITE ANALYSIS AND TRENDS...TWO CELLS SEEN ON IR IMAGERY ALONG
THE NRN TX COAST APPEAR AS THOUGH THEY WILL BE VERY PROBLEMATIC. BOTH
CELLS ARE SHOWING LITTLE MOVEMENT WITH 2340-2345Z VIS IMAGERY SHOWING
NEW CELLS INITIATING BETWEEN THEM. OVERSHOOTING TOPS ARE SEEN ALONG THE
BRAZORIA/FORT BEND COUNTY LINE WITH ANOTHER OVERSHOOTING STILL SEEN ON
THE STNRY CELL ALONG THE WHARTON/MATAGORDA COUNTY BORDER. CELL MOVING
SLOWLY SWD FROM S HARRIS COUNTY SHOULD CAUSE A MERGER ALONG THE FROT
BEND/BRAZORIA COUTNY LINE EXTENDING SWWD INTO THE OTHER CELL. RAINFALL
RATES OF 2-3"/30 MINS CAN BE EXPECTED FROM THE MERGING OF THESE CELLS IN
A VERY RICH ENVIRONMENT THAT FEATURES PW VALUES WELL OVER 2"...GPS/GOES
SOUNDER PW VALUES INDICATE NEAR 2.25". WITH THE VERY SLOW MOVEMENT SEEN
FROM CELLS..CAN EXPECT THE VERY LOW FFG TO BE EXCEEDED RAPIDLY.
