SATELLITE ANALYSIS AND TRENDS...SWD SINKING CELLS AT SRN END OF BOW ECHO
HAVE MERGED OVER SWRN WEBB COUNTY PER 0345Z IR IMAGE. CLOUD TOPS WERE
PREVIOUSLY COOLING AND EXPANDING IN RESPONSE TO THE MERGER WITH COLDEST
CLOUD TOPS OF -65C ACROSS THE RIO GRANDE FROM LRD. 0415Z IMAGERY DOES
SHOW THE EXPANDED CLOUD TOPS HAVE NOW SHRUNK BACK TO BE  SMALLER THAN
THE SIZE OF ZAPATA COUNTY AND ARE CENTERED OVER LRD. POSSIBLE THAT THIS
MERGER WILL SLOW CELL MOVEMENT AND CAUSE SLOW E/SE PROGRESSION OF CELLS
ALONG THE SRN END OF THE CELL CLUSTER. ESTIMATE RAINFALL AMOUNTS OF NEAR
1" HAVE ALREADY OCCURRED ALONG A W-E LINE INVOF LAREDO IN PAST 45-50
MIN AND RAINFALL RATES OF 1"/HR MAY CONTINUE IN SRN WEBB AND INTO SRN
DUVAL/NRN ZAPATA/NRN JIM HOGG OVER NEXT 1-2 HRS.
