...SYNOPSIS AND FORECAST...
AMPLIFICATION OF UPSTREAM RIDGE OVER THE GULF OF AK WILL RESULT IN A
SWD MOVEMENT OF MID/UPPER-LEVEL LOW /CURRENTLY CENTERED NEAR
46N/134W/ TO OFF THE CA COAST DURING THE DAY 2 PERIOD.
MEANWHILE...DOWNSTREAM PATTERN WILL FLATTEN ACROSS THE ERN
TWO-THIRDS OF THE NATION AS TROUGH INITIALLY OVER THE NERN STATES
MOVES INTO THE ATLANTIC. 

IN THE LOW-LEVELS...BROAD SURFACE RIDGE FROM THE GREAT LAKES INTO
THE NRN GULF OF MEXICO WILL SLOWLY SHIFT EWD TOWARD THE ATLANTIC
SEABOARD. IN THE W...PACIFIC COLD FRONT WILL MOVE ONTO THE CNTRL CA
COAST DURING THE LATTER HALF OF THE FORECAST PERIOD. AS THIS
OCCURS...ENHANCED OROGRAPHIC ASCENT IN IMMEDIATE POST-FRONTAL AIR
MASS WILL LEAD TO AN INCREASE IN SHOWERY PRECIPITATION ALONG
WINDWARD SIDE OF THE COASTAL RANGES. FORECAST SOUNDINGS SUGGEST THAT
GRADUALLY STEEPENING MID-LEVEL LAPSE RATES OWING TO CLOSE PROXIMITY
OF MID-LEVEL COLD POOL MAY RESULT IN SOME WEAK INSTABILITY AND
POTENTIAL FOR A FEW ISOLATED LIGHTNING STRIKES.
