THE THERMAL TROUGH ALONG THE COAST WILL EXTEND NORTH FRIDAY AND
COMBINE WITH HIGH PRESSURE OVER THE NORTHEAST PACIFIC TO TIGHTEN
THE PRESSURE GRADIENT OVER THE WATERS. NORTH WINDS WILL INCREASE
TO GALE FORCE LATE FRIDAY AND PERSIST THROUGH THE WEEKEND. AS A
RESULT...COMBINED SEAS WILL BUILD TO 10 TO 12 FT LATE FRI AND PEAK
AROUND 13 TO 16 FT SUN. THE GRADIENT RELAXES EARLY NEXT WEEK
ALLOWING WINDS AND SEAS TO GRADUALLY DIMINISH.

AND/OR LOCATION IS STILL UNCERTAIN. IT IS INTENDED TO PROVIDE
ADDITIONAL LEAD TIME FOR MARINERS WHO MAY WISH TO CONSIDER

AREA FORECAST DISCUSSION...UPDATED MARINE DISCUSSION.
NATIONAL WEATHER SERVICE EUREKA CA
256 PM PDT SUN JUN 27 2010

.SYNOPSIS...LOW MARINE CLOUDS WILL RETURN TO THE DEL NORTE AND
HUMBOLDT COASTS TONIGHT AND MONDAY MORNING. INLAND AREAS WILL HAVE
ONE MORE DAY OF ABOVE NORMAL DAYTIME TEMPERATURES MONDAY BEFORE AN
UPPER LEVEL TROUGH BRINGS GRADUAL COOLING TUESDAY THROUGH THURSDAY.

&&

.DISCUSSION...AFTERNOON WATER VAPOR IMAGERY SHOWS AN UPPER LEVEL
TROUGH DEEPENING OVER THE NE PACIFIC AND HIGH PRESSURE OVER THE
PACIFIC NW MOVING EASTWARD. LOW CLOUDS WILL RETURN TO THE HUMBOLDT
AND DEL NORTE COAST TONIGHT. THINK THE LOW CLOUDS WILL LINGER AT
LEAST ALONG THE IMMEDIATE HUMBOLDT COAST MOST OF MONDAY AS LOW LEVEL
MOISTURE INCREASES AHEAD OF THE APPROACHING TROUGH...AND THE N-S
SURFACE PRESSURE GRADIENT WEAKENS. THE PRESSURE GRADIENT WILL REMAIN
RELATIVELY TIGHT SOUTH OF CAPE MENDOCINO AND DO NOT EXCPECT MUCH IF
ANY FOG FORMATION ALONG THE MENDOCINO COAST TONIGHT. OTHERWISE...NW
CA WILL SEE ANOTHER SUNNY AND WARM DAY MONDAY...WITH DAYTIME HIGH
TEMPERATURES ONLY COOLING 1 TO 2 DEGREES FROM TODAY.

THE STRATUS WILL PUSH FURTHER INLAND EARLY TUESDAY MORNING AS A WEAK
VORT MAX MOVES ACROSS THE AREA. THE TROUGH WILL SLOWLY MOVE ACROSS
THE FORECAST AREA TUESDAY THROUGH THURSDAY AND THE EXTENT OF THE
COASTAL STRATUS WILL DECREASE EACH NIGHT. THE TROUGH WILL ALSO BRING
A GRADUAL COOLING TREND THIS WEEK WITH INLAND MAXIMUM TEMPERATURES
LOWERING TO THE MID 80S BY WEDNESDAY. TH

.LONG TERM (THU THRU SUN)...LONGWAVE TROUGH WILL BE SLOW TO EXIT THE
WESTERN CONUS AT THE END OF THE WEEK. MODELS IN VERY GOOD AGREEMENT
ON THE LARGE SCALE...BUT INDIVIDUAL SHORTWAVES REMAIN DIFFICULT TO
RESOLVE. THE GOOD NEWS IS THAT ANY SHORTWAVES THAT MOVE THROUGH
WILL BE MOSTLY MOISTURE STARVED...RESULTING IN MAINLY AFTERNOON CU
OVER THE MOUNTAINS. HIGH PRESSURE BEGINS TO BUILD IN THE EPAC BY SAT
AS NORTH WINDS ONCE AGAIN RAMP UP OFFSHORE. THE EXISTENCE/COVERAGE
OF STRATUS ALONG THE COAST DURING THIS TIME IS TOUGH TO
PINPOINT...BUT RIGHT NOW WE ARE GOING WITH AN OPTIMISTIC FCST DUE TO
THE INCREASED MIXING. TEMPERATURES WILL GRADUALLY INCREASE AS THE
TROUGH SHIFTS OFF TO THE EAST AND HEIGHTS BUILD. JCA

&&

.AVIATION...THE MAIN SHORT TERM AVIATION FORECAST CHALLENGE
CONTINUES TO BE THE EXTENT AND TIMING OF THE COASTAL STRATUS AND
FOG. AFTERNOON VISIBLE SATELLITE IMAGERY SHOWS AN EXPANSIVE AREA OF
LOW CLOUDS 10 TO 60 NM OFFSHORE OF NW CA QUICKLY MOVING TOWARDS THE
COAST. THERE IS ALSO A SLIVER OF IFR CEILINGS ALONG THE IMMEDIATE
COASTLINE OF HUMBOLDT AND DEL NORTE COUNTIES. EVIDENCE OF MICROSCALE
EDDIES ALONG THE COAST SUGGEST THAT THE STRATUS MAY NOT COMPLETELY
CLEAR THIS AFTERNOON BEFORE IT RETURNS THIS EVENING. THE STRATUS
WILL PERSIST AT LEAST THROUGH MONDAY MORNING.  OTHERWISE...VFR
CONDITIONS WILL PREVAIL. TH

&&

.MARINE...

UPDATE...REPORTS HAVE COME IN TO THE OFFICE THAT INDICATE A SHORTER
DOMINANT PERIOD OF THE WAVES IN ZONE 450. THE SHORTER PERIOD OF
THESE WAVES COULD MAKE WAVES HAZARDOUS TO SMALL CRAFT IN SOME
ISOLATED AREAS...APPROPRIATE CAUTION SHOULD BE TAKEN.

PREVIOUS DISCUSSION:

NORTHERLY WINDS WILL CONTINUE TO DROP ACROSS THE REGION
THROUGH THIS EVENING AND INTO MONDAY.  IN SOUTHERN ZONES...GUSTS
WILL FREQUENTLY TOP 25 KT IN ALL WATERS.  HOWEVER...IN NORTHERN
ZONES...CONFIDENCE IS HIGH THAT THERE SHOULD BE A 24 HOUR BREAK IN
STRONG WINDS IN THE NORTHERN ZONES...SUFFICIENT THAT THE SCA
ADVISORY ACROSS THE ENTIRE NORTHERN ZONE HAS BEEN DROPPED UNTIL
EARLY TUESDAY.  PAST TUESDAY...WINDS WILL RAMP UP AND AGAIN BRING
STEEP SHORT PERIOD SEAS TO THE REGION.  LATE WEEK WILL BRING THE
POSSIBILITIES FOR A NORTHERLY GALE AND HAZARDOUS SEAS EVENT.

THROUGHOUT THE TIME PERIOD...PRIMARY WAVES WILL BE OUT A NORTHERLY
DIRECTION AS WINDS WILL CREATE A FRESH SWELL IN THE LOCAL
ENVIRONMENT.  LONG PERIOD SOUTHERLY SWELLS ARE ALSO APPARENT IN THE
WATERS AND WILL BE PERSISTING THROUGH THE WEEK. THESE SWELLS ARE THE
RESULT OF FORMERLY MAJOR HURRICANE CELIA...AND TROPICAL STORM
DARBY.  GWW AND ENP MODELS PROG THE SOUTHERLY SWELLS FROM CELIA TO
ARIVE IN ERNEST BY THIS EVENING...AND SWELLS FROM DARBY BY
WEDNESDAY.  THE HEIGHTS OF THE SWELL FROM CELIA IS PROGGED TO COME
THROUGH AROUND 3 FEET AT 15 SECONDS. WITH THE MODELS INCONSISTENCIES
IN RESOLVING THE FINE SCALE WINDS ASSOCIATED WITH TROPICAL
CYCLONES... SLIGHTLY HIGHER SWELLS COULD COME TO THE LOCAL
ENVIRONMENT ON A TEMPORARY BASIS...NO SOUTHERLY WAVES SHOULD BE
HIGHER THAN 5 FEET HOWEVER.  MSB
