.SYNOPSIS...HIGH PRESSURE BUILDING OVER THE REGION WILL BRING
NORTHWEST CALIFORNIA DRY WEATHER THROUGH SUNDAY. THE COAST
CAN EXPECT BREEZY NORTH WINDS WHILE INTERIOR LOCATIONS WILL
EXPERIENCE CHILLY MORNING TEMPERATURES AND WARM AFTERNOONS.

&&

.SHORT TERM...(NOW THROUGH MONDAY NIGHT)...ANOTHER CHILLY MORNING
IS IN STORE AS MAINLY CLEAR SKIES COMBINE WITH DRY NORTHERLY
FLOW. THE COASTAL PRESSURE GRADIENT WILL RELAX A BIT TODAY THUS LESS
NORTHERLY WINDS AS THE PREVIOUS COUPLE DAYS. TEMPS WILL ALSO RISE A

HOWEVER THE LOW CLOUDS MAY RETURN TO THE COAST. ON MONDAY THE FIRST
OF A SERIES OF TROUGHS APPROACH THE WEST COAST.  MONDAY SHOULD BE
RAIN FREE HOWEVER MID AND HIGH LEVEL CLOUDS WILL LIKELY BE PRESENT.

.PREV LONG TERM...(TUESDAY MORNING THROUGH FRIDAY MORNING) BREAK DOWN
OF THE UPPER LEVEL RIDGE THROUGH TUESDAY WILL BRING AN END TO DRY
WEATHER AS A TROUGH SLIDES TOWARDS THE PACIFIC NW. MODELS PROG THE
TROUGH TO SPLIT HAVING THE NORTHERN WAVE BRING THE FIRST
OPPORTUNITY FOR RAIN LATER TUESDAY. THE REMAINING CLOSED LOW IS
PROGGED TO DIG SOUTHWARD MAINTAINING WET WEATHER THROUGH THE
EXTENDED FORECAST. POPS WERE INCREASED USING THE MRA MODEL
TUESDAY, WEDNESDAY, AND EARLY THURSDAY DUE TO INCREASING
CONFIDENCE WITH THE POSSIBILITY OF RAIN. HOWEVER, TIMING OF THE
RAIN IS STILL IN QUESTION WITH THE ECMWF SOMEWHERE BETWEEN 6 TO 12
HOURS FASTER THAN THE GFS. OTHERWISE MAINTAINED CLIMO POPS THROUGH
THE REMAINDER OF THE FORECAST DUE TO MODEL UNCERTAINTY. KML

BELOW GALE TODAY SOUTH OF THE CAPE...THOUGH SOME GUSTS TO 35 KT MAY
LINGER THIS MORNING, SO LEFT THE WARNING IN EFFECT TIL 11AM. MODELS

ON SUNDAY. BY MONDAY WINDS LOOK TO EASE UP EVEN MORE AS THE OFFSHORE
RIDGE WEAKENS IN RESPONSE TO AN APPROACHING TROUGH. GFS AND ECMWF
WERE SIMILAR ON THE WINDS GOING SOUTHERLY ON TUE AS BROAD AND
DIFFUSE LOW PRES DEVELOPS OFFSHORE. SEAS SHOULD FALL AS WELL BY
MON...AS LONGER PERIOD NW SWELL MIXES IN THROUGH WED.
