...DISCUSSION...

LATEST MEDIUM RANGE MODEL GUIDANCE SUGGESTS TROUGHING MAY BECOME
MORE ESTABLISHED ACROSS THE ERN U.S. BY THIS WEEKEND...LEADING INTO
EARLY NEXT WEEK. IF THIS EVOLUTION OCCURS STRONGER FLOW WOULD ONCE
AGAIN DROP SOUTH ACROSS MUCH OF THE CONUS EAST OF THE ROCKIES
ENHANCING THE LIKELIHOOD FOR ORGANIZED THUNDERSTORMS. AT THIS TIME
THERE IS TOO MUCH UNCERTAINTY REGARDING BUOYANCY AND POTENTIAL
CONVECTIVE FEEDBACK PRIOR TO STRENGTHENING WIND FIELDS.
