...DISCUSSION...
00Z DETERMINISTIC/ENSEMBLE MODELS ARE IN GOOD GENERAL AGREEMENT WITH
THE EXPECTED PERSISTENCE OF A RELATIVELY AMPLIFIED LARGE-SCALE
PATTERN INTO EARLY NEXT WEEK. THE PREVALENCE OF CENTRAL/EASTERN
CONUS HIGH PRESSURE AND COOL/STABLE CONDITIONS WILL LIKELY RESULT IN
LITTLE IF ANY SEVERE TSTM POTENTIAL THIS WEEKEND...ALTHOUGH TSTMS
WILL BE POSSIBLE ON DAY 4/SATURDAY ACROSS PARTS OF FL.

MEANWHILE...GRADUAL LARGE-SCALE TROUGH AMPLIFICATION IS EXPECTED TO
OCCUR OVER THE WESTERN STATES LATE THIS WEEKEND/EARLY NEXT WEEK.
ALTHOUGH THE TIMING/QUALITY IS A BIT UNCERTAIN...LOW-LEVEL MOISTURE
WILL GRADUALLY INCREASE ACROSS THE SOUTH-CENTRAL CONUS EARLY NEXT
WEEK TO THE EAST-SOUTHEAST OF A FRONTAL BOUNDARY/DRYLINE. THIS
SCENARIO WILL RESULT IN AN INCREASING POTENTIAL FOR TSTMS /SOME
POSSIBLY STRONG/ ACROSS THE SOUTHERN/CENTRAL PLAINS ON DAYS 6-8
MONDAY-WEDNESDAY.
