SATELLITE ANALYSIS AND TRENDS...IR IMAGERY SHOWS A SECOND COLD TOP
CLUSTER FOLLOWING ALONG THE SAME PATH THAT AN EARLIER COLD TOP CLUSTER
TOOK ACROSS DEEP SRN TX. WITH THE RAPID COLLAPSE OF THE FIRST CLUSTER AS
IT NEARED KRKP THE 2ND CLUSTER WAS RAPIDLY ENHANCED AS IT STARTED TO CROSS
THE RIO GRANDE INTO WEBB COUNTY. AN OVERSHOOTING TOP TO -67C WAS PRESENT
AT 1245Z OVER NW WEBB COUNTY AND PER LOOP OF IR/VIS IMAGERY THESE MOST
INTENSE TOPS HAVE STAYED RELATIVELY STNRY ALONG THE US/MX BORDER NW OF
LRD. TWO ADDTL OVERSHOOTING TOPS WERE FOLLOWING THE FIRST EWD ACROSS THE
BORDER WHICH IS LIKELY THE REASON WHY IT APPEARS AS THOUGH THE COLDEST
TOPS/MOST INTENSE RAINS HAVE BEEN ANCHORED OVER NW WEBB. 12Z PW ANALYSIS
INDICATED BETWEEN 1.6-1.8" WITH HIGHEST VALUES POOLED ALONG THE COAST
OF DEEP SRN TX. AUTOMATED STLT ESTIMATES INDICATE UP TO 1.2" IN THE PAST
HR ENDING 1315Z BUT EXPECT THAT THIS IS NOT ACCOUNTING FOR THE MULTIPLE
OVERSHOOTING TOPS WHICH ARE CROSSING THE SAME POINT IN WEBB COUNTY..LIKELY
RAINFALL AMOUNTS OF 2-3" HAVE OCCURRED IN THE LAST 1.5 HRS. THESE CELLS
SHOULD CONTINUE TO MOVE SLOWLY EWD SOON AS THE LAST OVERSHOOTING TOP
HAS JUST CROSSED THE RIO GRANDE IN 1345Z VIS IMAGE AND THEN EWD ACROSS
DUVAL/JIM WELLS COUNTIES. WITH SOME RAIN HAVING ALREADY OCCURRED E OF
THIS CLUSTER..ADDTL RAINFALL OVER THOSE AREAS WILL NEED TO BE MONITORED.
