...DISCUSSION...
SEASONALLY WEAK LARGE SCALE FLOW REGIME IS EXPECTED TO PERSIST
THROUGH THE UPCOMING MEDIUM RANGE PERIOD.  EVEN SO...SEVERAL
SHORT-WAVE TROUGHS WILL LIKELY PROGRESS ACROSS THE CONUS ENCOURAGING
DEEP CONVECTION IMMEDIATELY DOWNSTREAM.  WHILE VERTICAL SHEAR IS
EXPECTED TO BE INSUFFICIENT FOR PREDICTING ORGANIZED SEVERE...FROM A
DAY4-8 PERSPECTIVE...POCKETS OF HIGHER INSTABILITY WILL LIKELY
MODULATE SEVERE ON A DAY TO DAY BASIS.
