AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
950 PM PDT TUE JUN 30 2009

.SYNOPSIS...A WEAK LOW OFFSHORE MAY PROVIDE THE FOCUS FOR A FEW
THUNDERSTORMS OVER THE INTERIOR FOR THE LATTER HALF OF THE WEEK.
THIS LOW WILL ALSO HELP DEEPEN THE MARINE LAYER WITH COASTAL
LOCATIONS EXPERIENCING MORE CLOUDS AND FOG. TEMPERATURES WILL COOL
SLIGHTLY THROUGH THE END OF THE WEEK.

&&

.UPDATE...COASTAL SURGE HAS STALLED AT PUNTA GORDA WITH WINDS AT
BUOY 14 AND PT ARENA CMAN WEAK NORTHERLY. MODELS NOT CONSISTENT IF
OR WHEN IT WILL MOVE FURTHER NORTH. LATEST GFS/NAM KEEP STRATUS
SOUTH OF THE CAPE THROUGH WEDNESDAY WITH NAM HINTING AT MORE
SOUTHERLY FLOW ON THUR WHILE GFS MAINTAINS A N-E FLOW THROUGH THUR.
WITH WEAK UPPER LOW OFF THE COAST DRIFTING NORTH TO WEST OF
SFO...WOULD EXPECT IT TO START TO PUSH NORTH SO WILL STAY WITH
TIMING OF PULLING IT UP WED NIGHT...THOUGH CONFIDENCE IS LOW.
BIGGER PROBLEM WITH THIS LOW IS MOISTURE BEING PULLED UP INTO THE
EASTERN PORTION OF THE AREA. FEW CU OVER HIGHER ELEVATIONS THIS
AFTERNOON. MODELS HAVE BEEN CONSISTENT IN BRINGING MORE MOISTURE
INTO AREA WED WITH INCREASED AMOUNTS ON THUR. PREVIOUS THINKING OF
ISOLATED TSTMS WED AFTERNOON WITH BETTER CHANCE ON THUR STILL GOOD.
DEAN

.PREV DISCUSSION...A WEAK UPPER LEVEL LOW WELL OFF THE SOCAL COAST
(CURRENTLY NEAR 34N 129W) WILL LIFT NORTH WHILE MOVING TOWARD THE NW
CALIFORNIA COAST. DIFFLUENT FLOW AHEAD OF THIS FEATURE IN
COMBINATION WITH INCREASING MID LEVEL MOISTURE WILL SET THE STAGE
FOR ISOLATED THUNDERSTORMS OVER MAINLY TRINITY COUNTY BEGINNING WED
AFTERNOON. PWAT VALUES INCREASE TO 0.75 INCHES ON WED...PEAKING
AROUND 1 INCH ON THU. STRONG SFC HEATING ALONG WITH WEAK
DISTURBANCES ALOFT SHOULD TRIGGER ISOLATED THUNDERSTORMS. SFC BASED
INSTABILITY LOOKS RESPECTABLE WITH MID-LEVEL LAPSE RATES EXCEEDING 8
C/KM AND GRATER THAN 1000 J/KG OF CAPE. WITH LESS THAN 10 KTS OF
WINDS THROUGH 15KFT, STORMS WILL MAINLY BE CENTERED OVER THE HIGHER
TERRAIN AND REMAIN NEARLY STATIONARY. VERY LITTLE RAIN IS EXPECTED
WITH STORMS ON WED...WITH MORE MOISTURE AVAILABLE ON THU AS THE
ENTIRE COLUMN MOISTENS SLIGHTLY.

TEMPERATURES WILL REMAIN HOT INLAND WITH A SLIGHT COOLING TREND
ALONG THE COAST AS A MORE PERSISTENT STRATUS DECK DEVELOPS. A
STRATUS SURGE IS CURRENTLY STUCK JUST SOUTH OF CAPE MENDOCINO...BUT
WITH THE APPROACHING LOW AND RESULTING REVERSAL OF WINDS, THIS DECK
OF CLOUDS SHOULD MAKE IT OVER THE HUMP AND ENCOMPASS THE NORTH COAST
BY THU MORNING...AT THE LATEST.

A COOLING TREND FOR ALL OF NORTHERN CALIFORNIA COMMENCES ON FRIDAY
AS THE UPPER LOW WEAKENS FURTHER AND MOVES INLAND. A SLIGHT CHANCE
FOR CONVECTION WILL REMAIN FOR THE HIGHER TERRAIN AS THE TROUGH ONCE
AGAIN ACTS TO DESTABILIZE THE ATMOSPHERE. A LARGER TROUGH DIGGING
OFF THE PACNW COAST WILL CONTINUE THE COOLING TREND WITH PLENTY OF
CLOUDS ALONG THE COAST FOR THE HOLIDAY WEEKEND. JCA

&&

.AVIATION...FOG PRODUCT SHOWS MARINE STRATUS LINGERING ALONG THE
COAST S OF CAPE MENDOCINO THIS EVENING. DO NOT HAVE ANY CIG/VIS OBS
WITH THESE CLOUDS...BUT EXPECT MVFR CONDITIONS ALONG THE IMMEDIATE
COAST. MVFR HAZE AGAIN DEVELOPING ALONG THE COAST NORTH OF THE CAFE
THIS EVENING AND EXPECT IFR CONDITIONS EXPECTED AROUND HUMBOLDT BAY
AND THE EEL RIVER DELTA AGAIN DEVELOPING ABOUT SUNRISE WITH MVFR
CONDITIONS WITH TEMPO IFR VIS FURTHER N ALONG THE REDWOOD COAST IN
PATCHY GROUND FG. CONDITIONS WILL IMPROVE TO VFR BY LATE
MORNING/EARLY AFTERNOON AS STRATUS/FG DISSIPATES. ELSEWHERE...VFR
CONDITIONS WILL PREVAIL WITH CU BUILDUPS AND SCHC OF TSTMS WED
AFTERNOON ACROSS THE INTERIOR. DEAN/BC

&&

.MARINE...MADE ONLY MINOR CHANGES TO THE MARINE FORECAST TO EXTEND
STEEP SEAS THROUGH TONIGHT AS ONE SHIP REPORT HAD 45 KT WINDS SW OF
PT ST GEORGE AT 5PM THIS EVENING AND BUOYS 27...22...AND THE CAPE
MENDO AND HUMBOLDT BAY CDIPS ALL REPORTING SEAS 11-13 FT 9 SEC.

HIGH PRESSURE OVER THE PACIFIC AND LOW PRESSURE OVER THE INTERIOR
WILL CONTINUE TO PRODUCE MDT TO STRONG WINDS OVER THE OUTER WATERS
TONIGHT WITH GALES PERSISTING OVER THE THE NORTHERN OUTER WATERS
THROUGH WED MORNING. THE COMBINATION OF LARGE WIND WAVES AND STEEP
FRESH SWELL CONTINUES TO PRODUCE HAZARDOUS SEAS. A WEAK SFC LOW IS
OFF PT ARENA BUT IT IS WEAKENING AT WINDS AT BUOY 14 AND THE PT
ARENA CMAN HAVE TURNED LIGHT NORTHERLY. THIS LOW WILL CONTINUE TO
ALLOW THE PRESSURE GRADIENT TO RELAX ACROSS THE SOUTHERN WATERS.
WINDS AND SEAS WILL CONTINUE TO SLOWLY DIMINISH WED WITH LIGHT WINDS
AND LOW SEAS EXPECTED FROM WED NIGHT THROUGH THE WEEK AS THE SURFACE
HIGH PRESSURE WEAKENS WITH LOWER PRESSURE DEVELOPING ALOFT.
