   ...SYNOPSIS...
   UPPER FLOW REGIME WILL BE MORE AMPLIFIED ACROSS THE COUNTRY ON
   MONDAY.  AS THE MID-LEVEL IMPULSE CROSSING THE MIDWEST RAPIDLY
   TRANSLATES INTO THE NERN STATES EARLY TODAY...A SIGNIFICANT PIECE OF
   ENERGY WILL GET LEFT BEHIND...CLOSING OFF INTO AN UPPER LOW OVER THE
   SRN PLAINS.  THIS FEATURE WILL GRADUALLY TURN E TOWARD THE LWR MS
   VLY LATE MON NIGHT AS THE NEXT UPSTREAM NRN STREAM IMPULSE DROPS
   TOWARD THE PAC NW.  
   
   AT THE SURFACE...A COLD FRONT...ASSOCIATED WITH THE MIDWEST UPPER
   DISTURBANCE...WILL SETTLE SWD ACROSS THE TN VLY AND SRN PLAINS
   MONDAY.  ERN PORTIONS OF THE FRONT WILL SLOW AS A WEAK LOW DEVELOPS
   ALONG THE FRONT ACROSS THE ARKLATEX REGION BY MONDAY AFTN.  AS THIS
   LOW TRACKS EWD TOWARD NRN LA BY 12Z TUE...WRN PORTIONS OF THE
   BOUNDARY WILL BEGIN TO ACCELERATE SEWD OFF THE TX COAST.
    
   ...ERN TX THROUGH LOWER MS VALLEY AREA...
   BOUNDARY LAYER ACROSS THE WRN/CNTRL GULF STATES WILL CONTINUE TO
   MODIFY MONDAY. BY AFTN...SURFACE DEW POINTS WILL BE IN THE UPPER
   50S TO NEAR 60 DEGREE F INLAND TO THE MID 60S ALONG THE UPPER TX/LA
   COASTS.  MARGINAL INSTABILITY COULD DEVELOP IN THE PRE-FRONTAL WARM
   SECTOR WHERE HEATING IS THE STRONGEST. BUT... MODEST CAP NOTED IN
   00Z/10 SOUNDINGS WILL LIKELY PERSIST...PRECLUDING SURFACE BASED
   CONVECTION DURING PEAK HEATING.
   
   MORE LIKELY SCENARIO WILL BE FOR ELEVATED CONVECTION TO DEVELOP LATE
   IN THE AFTN WITHIN THE WARM CONVEYOR ACROSS THE LWR TN VLY...AND MON
   NIGHT ACROSS THE ARKLATEX REGION WHERE MID-LEVEL PROFILES COOL AND
   UVV ASSOCIATED WITH THE APPROACHING UPPER LOW BEGINS TO SPREAD SEWD.
    TSTMS WILL THEN DEVELOP EWD ACROSS THE NRN PARTS OF THE DEEP S AND
   SEWD ACROSS ERN TX AND WRN/NRN LA BY EARLY TUE. 
   
   ATTM...IT APPEARS THAT MUCAPES WILL REMAIN WEAK AND EFFECTIVE SHEAR
   MARGINAL ENOUGH TO PRECLUDE ORGANIZED SEVERE TSTMS.
