.
SATELLITE ANALYSIS AND TRENDS...VIS ANIMATION SHOWS CU/TCU ALIGNED IN S
TO NE CLOUD STREETS ACROSS E TX/LA AND EXTREME PORTIONS OF S AR AHEAD OF
THE SFC COLD FRONT.  MULTIPLE CONVECTIVE CELLS HAVE ALREADY DEVELOPED
AND ARE MOVING NEWD ACROSS CENTRAL AR AT THIS TIME.  MAIN CONCERN IS
FOR REDEVELOPMENT OF TSTMS UPSTREAM OF THE CURRENT CONVECTION WHERE
SFC CONVERGENCE IS STRONGER AND MID-LVL FLOW PER STLT DERIVED WINDS IS
ORIENTED PARALLEL TO THE SW/NE SFC COLD FRONTAL BOUNDARY.  A MOISTURE
PLUME STRETCHES FROM WESTERN GULF OF MEX NWD INTO E TX AND AR PER
GOES SOUNDER AND LATEST GOES AND GPS PW VALUES ARE BETWEEN 1.4-1.5"
ACROSS NE TX AND SW AR.  CONVECTION IS EXPECTED TO ORIGINATE OVER NE
TX..IN RESPONSE TO ENHANCED UVVS AHEAD OF UPPER-LVL JET MAX LOCATED OVER
CENTRAL TX..AND MOVE NE INTO SW/CENTRAL AR OVER THE NEXT SEVERAL HOURS.
EXPECTING HVY RAINFALL ACROSS THE DISCUSSION AREA AS  CELL MERGERS
AND TRAINING OF CELLS IS VERY LIKELY TO OCCUR.  EXPECTING TOTALS TO BE
BETWEEN 1-2"...POSSIBLY HIGHER IN LOCALIZED AREAS AS THESE STORMS MOVE
PARALLEL TO THE SFC BOUNDARY AND WITH MID-LVL FLOW.
