...SYNOPSIS...
LARGE CYCLONIC GYRE CENTERED OVER NRN MANITOBA...AND UPSTREAM RIDGE
FROM GREAT BASIN NWWD ACROSS BC/YUKON...DOMINATE UPPER AIR PATTERN
ACROSS MOST OF CONUS.  COLD FRONT ASSOCIATED WITH CANADIAN LOW WILL
CONTINUE MOVING NEWD FROM PRESENTLY ANALYZED POSITION OVER
NWRN/CENTRAL MN...SRN SD...NRN WY.  MEANWHILE...WAVY AND
OUTFLOW-MODIFIED FRONTAL ZONE IS ANALYZED FROM SERN QUE SFC LOW SWWD
ACROSS ERN NY...PA...THEN ROUGHLY DOWN OH VALLEY AND ACROSS
AR...INTO S-CENTRAL TX.  SRN PORTION OF THIS FRONT -- GENERALLY W OF
MS RIVER -- WILL BECOME QUASISTATIONARY AND INCREASINGLY DIFFUSE
AMIDST MULTIPLE CONVECTIVE OUTFLOWS.  MIDDLE PORTION WILL MOVE SEWD
INTO CENTRAL/SRN APPALACHIANS AND DECELERATE.  REST OF FRONT WILL
MOVE OFFSHORE MID ATLANTIC STATES AND ACROSS MOST OF NEW ENGLAND
DURING OVERNIGHT HOURS.

...SERN CONUS...
TWO PRIMARY BROKEN BANDS OF TSTMS CONTINUE TO MOVE GENERALLY EWD
ACROSS REGION --
1. ARCHING FROM SERN TN/NERN AL ACROSS PORTIONS CENTRAL/NRN GA TO
WRN SC...AND ALSO...
2. FROM SERN AR ACROSS ERN LA AND SRN MS.
DEEP-LAYER VERTICAL SPEED SHEAR DECREASES WITH SWD EXTENT AWAY FROM
BELT OF ENHANCED MID-UPPER LEVEL FLOW ASSOCIATED WITH CANADIAN
CYCLONE.  MARGINAL POTENTIAL FOR DAMAGING WIND LINGERS WITH ACTIVITY
ACROSS SRN PIEDMONT REGION AND WRN TN/NRN MS...WHERE ENVIRONMENT
AWAY FROM CONVECTIVE OUTFLOWS WILL REMAIN FAVORABLE FOR OCCASIONAL
DAMAGING GUSTS -- ESPECIALLY WHERE STORM-SCALE BOUNDARY INTERACTIONS
CAN BRIEFLY ENHANCE CONVECTIVE INTENSITY.  00Z RAOBS AND MODIFIED
RUC SOUNDINGS SUGGEST 1500-2000 J/KG MLCAPE IN ENVIRONMENTS
UNALTERED BY CONVECTIVE OUTFLOWS.  OVERALL TREND SHOULD BE TOWARD
