COAST WILL CONTINUE SHOWERS ACROSS THE AREA THROUGH TUESDAY MORNING.

NIGHT...WITH A FEW INCHES OF ACCUMULATION POSSIBLE TUESDAY MORNING.
HIGH PRESSURE AND DRIER WEATHER ARE EXPECTED FOR THE REST OF THE
WEEK...THOUGH A WEAK FRONT WILL CLIP THE THE NORTH COAST THURSDAY.

TURN ONSHORE THIS AFTERNOON AND EVENING WITH GUSTS AROUND 35 MPH.

SHOWERS WILL CONTINUE THROUGH TUESDAY MORNING WITH THE ONSHORE WINDS
THIS AFTERNOON AND EVENING FAVORING OROGRAPHIC ENHANCEMENT FOR THE
HIGHER TERRAIN OF THE COAST RANGE AND CASCADES. A MOIST ATMOSPHERE
REMAINS WITH PRECIPITABLE WATER VALUES NEAR AN INCH...AND WAVES
ROTATING AROUND THE LOW WILL PROVIDE ENOUGH LIFT TO PRODUCE ANOTHER 1
TO 2 INCHES OF RAIN FOR THE HIGHER TERRAIN THROUGH TONIGHT....AND 0.5
TO 1 INCH FOR THE LOW LANDS.

SNOW LEVELS WILL LOWER TO THE CASCADE PASSES LATE TONIGHT INTO
TUESDAY WITH 2 TO 4 INCHES OF SNOW ACCUMULATION POSSIBLE AROUND 4000
FEET. THE SNOW WILL NOT REMAIN ON THE GROUND TOO LONG HOWEVER AS A
STRONG UPPER RIDGE BUILDS TUESDAY.

A SUBSIDENCE INVERSION WILL SET UP TUESDAY AFTERNOON FOR WARM
TEMPERATURES FOR THE HIGHER TERRAIN WEDNESDAY AND THURSDAY...AND
TEMPERATURES FOR THE HIGHER TERRAIN WILL WARM. EXPECT FOG...LOW
CLOUDS AND COOLER TEMPERATURES FOR THE INTERIOR VALLEYS. THE UPPER
RIDGE WILL MOVE EAST WEDNESDAY NIGHT AND A COLD FRONT CURRENTLY
APPROACHING 140W WILL APPROACH THE OREGON AND WASHINGTON COAST. THIS
FRONT WILL WEAKEN AS IT NEARS...AND BE STEERED NORTHWARD OVER THE
UPPER RIDGE. THE FRONT MAY CLIP THE EXTREME NW PORTION OF THE
PORTLAND FORECAST AREA...FOR LIGHT RAIN...BUT OTHERWISE JUST BRING A
MIX OF MID AND HIGH LEVEL CLOUDS ACROSS THE REGION. TJ

LONG TERM...THURSDAY NIGHT THROUGH SUNDAY NIGHT...GENERAL HIGH
PRESSURE ALOFT WILL REMAIN THROUGH SATURDAY FOR WARMER AND DRIER
CONDITIONS THAN NORMAL. INLAND VALLEYS WILL BE THE EXCEPTION...WITH
PERSISTENT FOG AND LOW CLOUDS TRAPPED UNDER STRONG TEMPERATURE
INVERSIONS. A WEAK FRONTS WILL BRUSH BY THE NORTH COAST WITH CLOUDS
AND A LITTLE LIGHT RAIN THURSDAY NIGHT AND FRIDAY...BUT OTHERWISE NO
STRONG SYSTEMS ARE EXPECTED. AN UPPER LEVEL TROUGH FROM WESTERN
CANADA WILL SLIDE SOUTHWARD...MAINLY OVER LAND TOWARDS OREGON
SATURDAY NIGHT AND SUNDAY. IF THIS PANS OUT...CONVECTIVE SHOWERS ARE
POSSIBLE OVER THE HIGHER TERRAIN SUNDAY...AND POSSIBLY SOME COOLING.

SOUTHWESTERLY AFTER 20Z. OVERALL...MOSTLY VFR TODAY WITH POCKETS
OF MVFR CIGS UNDER SHOWERS. CIGS WILL LOWER TO LOW VFR AND EVEN

HEAVIER SHOWERS TODAY INTO THIS EVENING. SHOWERS DECREASE TONIGHT
