..DISCUSSION
AN UPPER-AIR PATTERN FEATURING A RIDGE OVER THE CENTRAL STATES WILL
QUICKLY TRANSITION TO A MORE PROGRESSIVE FLOW REGIME TOWARDS EARLY
THIS WEEKEND. MODEL GUIDANCE IMPLIES A SPLIT-FLOW REGIME
POTENTIALLY EVOLVING WITH TROUGHING OVER THE GREAT LAKES TOWARDS THE
SUNDAY-MONDAY TIMEFRAME (D7-D8). OVERALL LIMITED POTENTIAL FOR
ORGANIZED SEVERE SEEMINGLY EXISTS FOR MUCH OF THE EXTENDED PERIOD.
SOME INDICATION FOR A MOIST SECTOR EVOLVING AHEAD OF THE AMPLIFYING
GREAT LAKES' TROUGH COULD YIELD SOME SEVERE RISK, BUT PREDICTABILITY
IS LOW AND HIGHLY UNCERTAIN GIVEN MODEL SPREAD AT THIS POINT IN
TIME.
