SATELLITE ANALYSIS AND TRENDS...PERSISTENT MCS ACROSS CENTRAL TX
AT THE NOSE OF THE LLJ CONTINUES TO REDEVELOP CONVECTION WITH STRONG
FRONTOGENESIS OCCURRING ACROSS THE N PORTIONS OF SJT CWA.  GOOD ISENTROPIC
LIFT FROM THE MOIST (1.5 PLUS PW) LLJ HAS LEAD TO GOOD CONVECTIVE GROWTH
AND COOLING OF THE COMPLEX WHICH HAS LEAD TO AUTO SATELLITE ESTIMATES
OVER 3" IN THE LAST 3 HOURS OVER NOLAN AND TAYLOR COUNTIES.  RECENT IR
HOWEVER SHOWS A WARMING TREND OF THE COMPLEX WITH A MORE OF WEDGE SHAPE
OCCURRING TOWARD THE APPROACHING DEEPER CONVECTION AT THE NORTHERN END
OF THE SQUALL LINE (COKE COUNTY).  THIS WILL EVENTUALLY ROB THE NORTHERN
COMPLEX OF MOISTURE AND TRANSFER ISENTROPIC LIFT SWWARD AS THE INVERTED
TROF DEEPENS OVER THE BIG BEND REGION...ISALLOBARICALLY TURNING THE LLJ
TOWARD THE RIO GRANDE REGION (AS IS SEEN BY BETTER DEVELOPMENT OF SWWARD
FILLING IN).  THIS IS ALSO AIDED BY UPPER LEVEL DIFFLUENCE FROM THE JET
STRUCTURE OVER N MEXICO SHIFTING SWARD AS WELL AS THE JET DOES SO PER
WV LOOP.  EASTWARD TRACKING SQUALL LINE SHOULD CONTINUE ON ITS TRACK
BUT SINCE IT IS FAIRLY PROGRESSIVE AND MOVING ACROSS AREAS THAT HAVE NOT
BEEN AFFECTED BY RAINFALL...FF THREAT WILL DECREASE OVER CENTRAL TX AND
CONTINUE TO SHIFT SOUTH.  THOUGH WILL CONTINUE TO MONITOR...
