...SYNOPSIS...
UPPER TROUGH NOW EMERGING ONTO THE CNTRL/NRN HIGH PLAINS WILL
DEAMPLIFY AND SHEAR EWD ACROSS THE GREAT LAKES AND INTO NRN NEW
ENGLAND BY NEW YEARS DAY.  UPSTREAM COMPLEX UPPER LOW WILL SETTLE
SWD ALONG THE PAC NW COAST.  A SERIES OF SHORTWAVE TROUGHS WILL
EJECT EWD FROM THIS SYSTEM...THE STRONGEST OF WHICH WILL MOVE ACROSS
CA EARLY FRIDAY AND THEN TO THE FOUR CORNERS REGION BY EARLY NEW
YEARS DAY.  AT THE SURFACE...IN WAKE OF THE FIRST UPPER
DISTURBANCE...A COLD FRONT WILL MOVE SWD THROUGH THE NRN PLAINS AND
GREAT LAKES REGION THROUGH FRIDAY.  THIS FRONT WILL PROBABLY STALL
IN THE CNTRL PLAINS AND UPPER MIDWEST AS LOW-MID LEVEL FLOW BACKS
AHEAD OF THE UPSTREAM FOUR CORNERS TROUGH BY NEW YEARS DAY.

...ERN MI...
AS THE SHEARING UPPER SHORTWAVE TROUGH PASSES ACROSS THE GREAT
LAKES...LARGE SCALE ASCENT COUPLED WITH STEEP MID-LEVEL LAPSE RATES
MAY BE SUFFICIENT FOR A FEW ELEVATED TSTMS EARLY FRIDAY ACROSS ERN
MI.  THESE TSTMS WILL MOVE INTO SWRN ONTARIO BY MID-DAY.

...PAC COAST...
COLD H5 TEMPERATURES WITHIN CYCLONIC FLOW REGIME WILL CONTRIBUTE TO
MARGINALLY UNSTABLE AIR MASS ALONG THE PAC COAST FROM ORE SWD INTO
CNTRL CA ON FRIDAY.  HIGHEST TSTM POTENTIAL WILL BE EARLY IN THE
PERIOD AS WARMING MIDLEVELS/HEIGHT RISES QUICKLY TRANSLATE INTO THE
REGION FRIDAY NIGHT.

...CNTRL/SRN PLAINS...
LOW-MID LEVEL FLOW WILL GRADUALLY BACK ACROSS THE SRN/CNTRL PLAINS
FRIDAY NIGHT OWING TO APPROACH OF THE UPSTREAM TROUGH. STRONGEST
ISENTROPIC LIFT SHOULD EVOLVE ACROSS SRN KS/NRN OK WHERE ELEVATED
INSTABILITY MAY BE SUFFICIENT TO SUPPORT A FEW TSTMS.
