VALID 121200Z - 131200Z.

...NO TSTM AREAS FORECAST...

...SYNOPSIS...
AMPLIFIED AND PROGRESSIVE UPPER LEVEL FLOW WILL REMAIN THE PROMINENT
WEATHER PATTERN INTO THE DAY 2 FORECAST PERIOD.  MEAN UPPER RIDGE
WILL REMAIN ACROSS THE WRN STATES AS DEEP ERN STATES TROUGH
DE-AMPLIFIES AS IT TRACKS OVER NOVA SCOTIA/ERN CANADA ON SUNDAY. 
NEXT UPSTREAM TROUGH...NOW OVER ALBERTA...WILL CARVE OUT A BROAD
TROUGH FROM THE GREAT LAKES REGION/NERN STATES SWD TO THE OH/TN
VALLEYS BY 12Z MONDAY. MEANWHILE...STRONG PACIFIC TROUGH /CURRENTLY
LOCATED AT 36N 138W/ WILL DE-AMPLIFY AS IT MOVES NEWD ACROSS WA/ORE
AND INTO THE MEAN WRN RIDGE.

AT THE SURFACE...SURFACE LOW ASSOCIATED WITH ALBERTA CLIPPER SYSTEM
WILL MOVE ACROSS THE GREAT LAKES AREA WITH THE TRAILING COLD FRONT
MOVING SEWD/SWD OVER THE OH/TN VALLEYS AND SOUTH CENTRAL STATES. 
COLD AIR SPREADING OVER THE WARM WATERS OF THE GREAT LAKES WHICH
CURRENTLY RANGE FROM 5-9 C WILL RESULT IN STEEPENING SURFACE-3 KM
LAPSE RATES.  THIS WILL SUPPORT AN INCREASING THREAT FOR CONVECTIVE
LAKE EFFECT SHOWERS IN LEE OF THE LAKES...BUT OVERALL LIGHTNING
COVERAGE IS EXPECTED TO REMAIN TOO LOW TO WARRANT A GENERAL
THUNDERSTORM OUTLOOK.
