AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
755 PM PDT THU JUN 3 2010

.SYNOPSIS...ANOTHER STRONG LATE SEASON LOW PRESSURE SYSTEM WILL
PRODUCE ADDITIONAL RAIN THROUGH TONIGHT. A WEAK FRONT WILL ALSO
BRING LIGHT RAIN OR DRIZZLE TO THE AREA SATURDAY NIGHT INTO SUNDAY
MORNING. A DRIER WEATHER PATTERN IS EXPECTED FOR EARLY NEXT WEEK
AS HIGH PRESSURE BUILDS OFFSHORE.

&&

.UPDATE...ADDED ISOLATED THUNDERSTORMS TO THE FORECAST THROUGH 06Z...
MAINLY IN THE VICINITY OF CRESCENT CITY WHERE A FEW LIGHTNING
STRIKES HAVE BEEN DETECTED. BETTWY

&&

.DISCUSSION...MAIN FORECAST FOCUS IS ONGOING RAIN EVENING. ONSET OF
PRECIP CAME IN A BIT EARLIER THAN PREVIOUSLY EXPECTED WITH THE WARM
AIR ADVECTION...BUT GFS SEEMED TO HANDLE THE TIMING THE BEST. THIS
WAA BATCH OF RAIN HAS PUSHED THROUGH MUCH OF THE AREA...WITH THE
HEAVIER BANDS NOW BEGINNING TO AFFECT CRESCENT CITY...WHICH IS
SEVERAL HOURS AHEAD OF EXPECTED TIMING. NEVERTHELESS...THE PINEAPPLE
EXPRESS MOISTURE FEED AND ELONGATED VORT MAX LOOK TO BE ORIENTED SO
THAT BANDS WILL CONTINUE TO TRAIN OVER THE REGION TONIGHT. IR
SATELLITE IMAGERY ALSO SHOWS SWATH OF COOLER CLOUD TOPS STRETCHING
OUT TO NEAR 130W.  PLACING OF SHORT WAVE THIS AFTERNOON PER WATER
VAPOR IMAGERY LOOKS CLOSE TO PLACEMENT THE 12Z GFS HAS AS WELL...SO
FORCING SHOULD CONTINUE TONIGHT...AND HAVE MAINTAINED CATEGORICAL
POPS. WILL MONITOR FOR POSSIBLE UPDATES ON TIMING.  50+KT LOW LEVEL
JET ALSO STRENGTHENS ALONG THE NORTHERN COAST...PROVIDING ADDITIONAL
LIFT/MOISTURE. SFC WINDS ALONG THE NORTH COAST NEAR CRESCENT CITY
LOOK TO REACH ADVISORY CRITERIA TONIGHT...AND A WIND ADVISORY HAS
BEEN ISSUED ACCORDINGLY.  RAIN SHOULD END FRIDAY WITH MAIN
FROPA...WITH JUST SOME SHOWERS EXPECTED THROUGH THE DAY.
TEMPERATURES REMAIN WARM WITH THIS RAIN EVENT SO NO SNOW CONCERNS
EXIST.

FORECAST FOR THE WEEKEND REMAINS A BIT UNCERTAIN AS FLOW IS WSW
ZONAL AND ANY WEAK SHORT WAVES HAVE BEEN HARD FOR THE MODELS TO
RESOLVE. HAVE INCREASED CHANCE POPS FOR THIS WEEKEND HOWEVER AS
MODELS HAVE BEGUN ONCE AGAIN TO ADVERTISE A TRAILING FRONT PUSHING
THROUGH SATURDAY NIGHT/SUNDAY. LOOKS LIKE WE WILL GET A MORE
SUMMER LIKE PATTERN FOR EARLY IN THE WEEK WITH HIGH PRESSURE
OFFSHORE AND NORTHERLY FLOW ALONG THE COAST. ALTHOUGH MANY
DIFFERENCES EXIST BETWEEN EXTENDED MODELS...THE LOW CURRENTLY
ANCHORED OVER THE GULF OF ALASKA LOOKS TO DIVE SOUTHEAST AND BRING
SEASONABLY COOL TEMPERATURES LATE NEXT WEEK. HENRY

&&

.AVIATION...RAIN...HEAVY AT TIMES WILL CONTINUE OVERNIGHT WITH
WIDESPREAD MVFR CIGS. IFR CONDS CURRENTLY ALONG THE REDWOOD COAST
SHOULD LIFT LATER THIS EVENING AS SOUTH WINDS RAMP UP. CONFIDENCE ON
THE RISING CEILINGS IS MARGINAL AS GUIDANCE KEEPS KCEC AND KACV
SOCKED IN WITH IFR CIGS ALL NIGHT. ANOTHER CONCERN WILL BE THE WINDS
AT KCEC. SOUTHERLY GUSTS AS HIGH AS 40 KTS CAN BE EXPECTED AFTER
04Z...WINDING DOWN AFTER 10Z. ONCE THE -RA TAPERS OFF FRI
MORNING...BR/FG SHOULD LINGER. JCA

&&

.MARINE...A 1001 MB LOW WILL TRACK ACROSS THE EPAC INTO WEST CENTRAL
OREGON LATE TONIGHT. STRONG SOUTH WINDS WILL DEVELOP THIS EVENING
AHEAD OF THE TRAILING COLD FRONT. GALE/HAZ SEAS WARNING ARE ALREADY
POSTED FOR THIS EVENT OVERNIGHT ACROSS THE NORTHERN WATERS. A STEEP
WESTERLY SWELL PEAKING AROUND 11 FT AT 10 SEC WILL ENTERS THE WATERS
BY FRI AFTERNOON. WINDS WILL AGAIN TURN SOUTHERLY AHEAD OF ANOTHER
WEAK LOW PASSING TO THE NORTH SAT NIGHT. THE W SWELL WILL SLOWLY
SUBSIDE INTO EARLY NEXT WEEK AS WINDS TURN NORTHERLY IN RESPONSE TO
HIGH PRESSURE BUILDING OFF THE COAST. JCA
