PRIMARY CONCERN IS MARINE CLOUDS IN THE NEAR TERM FOLLOWED BY

PRECIP CHANCES AND AMTS ON SUNDAY. MARINE STRATUS IS ALREADY

EVIDENT WELL OFFSHORE AND WILL INCREASE IN COVERAGE AFFECTING COASTAL

REGIONS LATE TONIGHT AS HEIGHTS FALL AND WINDS TURN S. LOW CLOUDS

MAY STILL HAVE TIME TO MIX OUT IN THE AM ON SAT NEAR THE COAST BUT

THEIR ABSENCE WILL BE SHORT LIVED AS ONSHORE FLOW INCREASES. A

WEAK FRONT ASSOCIATED WITH A LOW OFF THE BC COAST WILL COME

ONSHORE DURING THE DAY SUNDAY. COMBINED WITH STRONG Q FORCING THE

MID LEVELS...COULD SEE A COUPLE TENTHS AT THE COAST WITH HIGHER

AMOUNTS IN FAVORED LOCS...ESP IN N AREAS OF THE FA. INCREASED POPS

RUN-TO-RUN CONTINUITY ON HANDLING OF RIDGING UPSTREAM OF THIS

RELATIVELY WEAK LOW BEFORE INCREASING POPS ANY FURTHER. FEW

CHANGES MADE FOR NEXT WEEK EXCEPT TO TWEAK POPS FOR TIMING IN

INCREASINGLY PROGRESSIVE FLOW REGIME. CLARK
