SATELLITE ANALYSIS AND TRENDS...ALONG A NARROW W-E STRETCH IN CENTRAL TX
A LINE OF INTENSE TSTMS ARE MOVING NEARLY DUE E LEADING TO INDIVIDUAL
CELLS TRAINING OVER THE SAME AREAS. COUNTIES OF CONCERN INCLUDE
JONES..SHACKELFORD..STEPHENS WHERE HVY RAINS ARE EXPECTED TO CONTINUE
FOR AT LEAST THE NEXT HR.  IR IMAGERY SHOWS VERY COLD TOPS OVER THIS
AREA AROUND -68C..WITH VIS SHOWING OVERSHOOTING TOPS WITH INDIVIDUAL
CELLS EMBEDDED WITHIN THIS LINE.  MANUAL STLT RAINFALL RATE TECHNIQUE
SUGGESTS RATES MAY REACH UPWARDS TO 1.5-2.0"/HR WITHIN THIS LINE..WITH
HIGHER AMOUNTS ACCOUNTING FOR CELL MERGERS.  THESE RATES ARE BASED ON
CLOUD TOP TEMPS REMAINING NEARLY CONSTANT FOR THE LAST HR AND THE SLOW
NATURE OF THIS LINE.  WILL CONTINUE TO MONITOR TO SEE IF LINE HOLDS
TOGETHER AND TRAINING OF CELLS CONTINUE POTENTIALLY WARRANTING ANOTHER
MESSAGE FOR COUNTIES JUST TO THE EAST OF THE THE ONES MENTIONED IN THIS
MESSAGE AS 23Z SFC MOISTURE DIVERGENCE IS SEEN TO BE STRONGER TO THE S
