EVENT...REPEATING CELLS WITH HVY RAIN
.
SATELLITE ANALYSIS AND TRENDS...LOW LVL WINDS HAVE BECOME MORE SRLY ACROSS
S TX IN ADVANCE OF FRONTAL BDNRY THAT CONTINUES TO BE SHOVED SWD BY AN
APPROACHING S/WV TROF SEEN ON WV IMAGERY DROPPING THROUGH E CO/NW KS/E
NE. BEST INSTABILITY PER GOES SOUNDER HAS SHIFTED TO THE E OVER THE LAST
FEW HRS AND IS NOW LOCATED NE OF KDRT. LARGE CLUSTER OF TSTORMS MOVING
EWD THROUGH CENTRAL TX HAS BEGUN TO SHOW RAPID WEAKENING ON IR STLT LOOP
THOUGH ANOTHER GROUP OF CELLS IS FOLLOWING ALONG BEHIND IT AND CROSSING
THE SAME COUNTIES WITH ADDTL HVY RAIN. 2ND CLUSTER OF CELLS HAS CLOUD
TOP TEMPS OF -55 TO -58C BUT OF MOST CONCERN IS THAT 1102Z IMAGE ALONG
WITH RADAR/LIGHTNING DATA SHOW HOW CELLS HAVE STARTED TO FILL IN FROM
SCHLEICHER COUNTY TO LLANO COUNTY. AUTOMATED STLT ESTIMATES INDICATE
UP TO 1.2" IN PARTS OF LAMPASAS/CORYELL COUNTIES AND SLIGHTLY LESS TO
THE S WHERE THE W-E ORIENTED CELLS ARE TRYING TO SET UP..THOUGH SOME
SLIGHT UNDERESTIMATION MAY HAVE OCCURRED. STNRY BNDRY APPEARS TO EXTEND
EWD FROM NEAR KBBD SO IT IS A GOOD BET THAT CELLS WILL TRAIN FROM W-E
FOR THE NEXT FEW HRS THOUGH WITH FAIRLY HIGH FFG..STILL MAY BE ABLE TO
MOST OF THE HVY RAINFALL. ALSO BEST LOW LVL MOISTURE CNVG IS NEAR KDRT
STILL SO SOME SWWD DVLPMT MAY PULL THE GROUP OF CELLS SWD AS IT SWINGS
THROUGH S CENTRAL TX. COULD SEE RAIN RATES OF UP TO 1-1.5"/HR WITH THE
TRAINING CELLS IN A SEMI-MOIST ENVIRONMENT..WITH PW VALUES OF 1-1.4".
