   VALID 311200Z - 051200Z
   
   ...DISCUSSION...
   PACIFIC TROUGH MOVING ACROSS THE CENTRAL ROCKIES ON DAY 3 IS PROGGED
   TO TRACK NEWD ACROSS THE NRN PLAINS ON TUESDAY DAY 4...AS IT PHASES
   WITH A MID LEVEL TROUGH INITIALLY LOCATED OVER THE NRN HIGH PLAINS.
   HOWEVER...STRONGER INSTABILITY IS EXPECTED TO REMAIN SOUTH ACROSS
   TX.
   
   OPERATIONAL MEDIUM RANGE MODELS ARE IN GOOD AGREEMENT WITH THE TRACK
   AND TIMING OF THE NEXT UPSTREAM PACIFIC TROUGH EXPECTED TO MOVE
   INLAND ACROSS THE NWRN STATES ON DAY 4 AND REACH THE NRN PLAINS ON
   THURSDAY DAY 6.  INCREASING MID LEVEL WINDS/DEEP LAYER SHEAR ACROSS
   PORTIONS OF THE CENTRAL/SRN PLAINS COMBINED WITH STRONG MOISTURE
   RETURN AND SUFFICIENT INSTABILITY SUGGEST THE POTENTIAL FOR SEVERE
   STORMS ACROSS MUCH OF THE CENTRAL/SRN PLAINS THURSDAY AFTERNOON INTO
   THURSDAY NIGHT.
