...DISCUSSION...
AN AMPLIFIED LARGE-SCALE PATTERN WILL EXIST OVER THE CONUS THROUGH
EARLY NEXT WEEK...ALTHOUGH GUIDANCE VARIABILITY EXISTS REGARDING THE
EXACT DEGREE OF TROUGH AMPLIFICATION AND TIMING OF LOW-AMPLITUDE
FEATURES OVER NORTHERN ONTARIO AND THE GREAT LAKES. INCREASING
LOW-LEVEL MOISTURE AND A SEMI-PERSISTENT BELT OF MODERATELY STRONG
WEST-NORTHWESTERLY UPPER-LEVEL WINDS OVER THE UPPER MIDWEST/GREAT
LAKES WILL LEAD TO AT LEAST SOME DAILY POTENTIAL FOR STRONG TO
SEVERE THUNDERSTORMS. WHILE CONFIDENCE IS NOT HIGH IN THE DAILY
DETAILS...MULTIPLE ROUNDS OF STRONG THUNDERSTORMS MAY BE POSSIBLE
ACROSS PARTS OF THE UPPER MS VALLEY/MIDDLE MO VALLEY/MIDWEST
SATURDAY THROUGH MONDAY /DAYS 4-6/ AHEAD OF A SOUTHEASTWARD-MOVING
FRONT.
