   ...NO TSTM AREAS FORECAST...
   
   ...SYNOPSIS/FORECAST...
   THE UPPER LOW MOVING ACROSS THE GRT BASIN IS EXPECTED TO MOVE
   THROUGH THE CNTRL ROCKIES EARLY SUNDAY WHILE PHASING WITH A NRN
   STREAM IMPULSE DROPPING THROUGH THE CANADIAN PRAIRIES. ULTIMATELY
   ...THIS WILL RESULT IN THE EVOLUTION OF A LARGE SCALE POSITIVE TILT
   TROUGH DOMINATING THE WRN TWO-THIRDS OF THE NATION BY EARLY MONDAY. 
   IN THE LOWER LEVELS...A COLD FRONT ASSOCIATED WITH THE DEVELOPING
   TROUGH WILL MOVE SWD THROUGH THE PLAINS AND BY 12 UTC MONDAY WILL
   EXTEND FROM LK SUP TO CNTRL OK TO SWRN TX. 
   
   STRENGTHENING ENTRANCE REGION OF A STRONG MIDLEVEL JET ON THE ERN
   SIDE OF DEVELOPING LONGWAVE TROUGH WILL ENHANCE LOW LEVEL FLOW FROM
   THE WRN GULF BASIN INTO THE SRN PLAINS SUNDAY AND MONDAY.  RECENT
   PENETRATION OF CP AIR MASS INTO THE SRN GULF SUGGESTS THAT MSTR
   RETURN WILL INITIALLY BE WEAK. HOWEVER...INCREASING MOIST/WARM
   ADVECTION AHEAD OF THE UPPER TROUGH/COLD FRONT WILL AT LEAST
   CONTRIBUTE TO AN INCREASE IN ELEVATED CONVECTION ACROSS CNTRL/SRN TX
   BY SUNDAY NIGHT.  ISOLD TSTMS CANNOT BE RULED OUT...BUT THEY WILL
   LIKELY BE SPARSE ENOUGH TO NOT INCLUDE IN A GENERAL TSTM RISK ATTM.
   
   ELSEWHERE...TSTMS ARE NOT EXPECTED.
