AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
933 AM PDT WED SEP 24 2008

.SYNOPSIS...A WEAK FRONT MOVING TO THE NORTH OF THE AREA WILL
BRING A CHANCE OF SHOWERS TO DEL NORTE COUNTY TODAY INTO TONIGHT.
EXPECT FAIR WEATHER FOR THE REM AIDER OF THE WEEK.

&&

.UPDATE...AMENDED ZFP/SKY GRIDS TO ACCOUNT FOR EARLY CLEARING THIS
MORNING INLAND. SUSPECT APPROACHING TROUGH WILL BRING INCREASING
CLOUD COVER LATER IN THE DAY...AND HAVE TRENDED THIS IDEA INTO THE
UPDATED FORECAST GRIDS. MC

&&

.SHORT TERM...TODAY THROUGH SATURDAY...SATELLITE IMAGERY SHOWS THE
TROUGH AXIS IS OFF THE WEST COAST. THE FRONT ASSOCIATED WITH THIS
TROUGH WILL MOVE TO THE NORTH OF THE REGION WITH SOME RAIN
POSSIBLY MAKING IT TO DEL NORTE COUNTY. STILL GOING WITH THE
CHANCE OF LIGHT RAIN TO THE NORTH OF KLAMATH LATE TODAY INTO
TONIGHT. THE REDWOOD COAST MAY ALSO SEE FOG AND DRIZZLE TONIGHT.
ANY PRECIPITATION ASSOCIATED WITH THE FRONT WILL MOVE OUT THURSDAY
MORNING AS THE TROUGH AXIS SWINGS THROUGH THE REGION. DRY AIR WILL
THEN WORK ITS WAY BACK INTO THE REGION. ENOUGH OFFSHORE FLOW
THURSDAY MAY ALLOW FOR CLEAR SKIES ACROSS THE ENTIRE AREA THROUGH
FRIDAY. NEAR SEASONAL TEMPERATURES WILL CONTINUE FOR THE REST OF
THE WEEK. MS

.LONG TERM...SATURDAY THROUGH WEDNESDAY...MODEL CONSISTENCY IS QUITE
GOOD FOR THE PERIOD. NEAR NORMAL TEMPERATURES ARE EXPECTED FOR THE
WEEKEND WITH AFTERNOON SUNSHINE LIKELY ALONG THE COAST. INCOMING
TROUGH SLATED FOR EARLY NEXT WEEK LOOKS LIKE IT WILL PRODUCE AT
LEAST SOME RAIN...WITH THE OPTIMUM TIME LATE TUESDAY AND TUESDAY
NIGHT. WE HAVE BOOSTED POPS INTO THE CHANCE CATEGORY FOR HUMBOLDT
AND DEL NORTE COUNTIES...WHICH WILL PROBABLY NEED FURTHER UPWARD
ADJUSTMENT. IT IS WORTH NOTING THAT THIS SYSTEM DOES NOT LOOK
PARTICULARLY VIGOROUS BUT IT DOES HAVE A RESPECTABLE PRECIPITABLE
WATER TAP SO PRECIP AMOUNTS MAY END UP BEING HEAVIER THAN ONE
MIGHT EXPECT FROM A SYSTEM WITH THESE CHARACTERISTICS. NCEP
ENSEMBLES FROM 23/00Z SUGGEST AT LEAST A SLIGHT CHANCE OF A HALF
INCH OF RAIN OR MORE OVER ALL OF OUR COUNTIES DURING THE TUESDAY
NIGHT TIME FRAME...AND THE 00Z AND 06Z OPERATIONAL GFS WAS PRETTY
CONSISTENT WITH THIS IDEA ALTHOUGH HINTED AT A BIT MORE RAIN NORTH
OF MENDOCINO COUNTY. BURGER

&&

.AVIATION...IFR/LIFR CIGS AND VSBYS DEVELOPED ALONG THE IMMEDIATE
COAST NORTH OF THE CAPE LAST EVENING WITH CEILINGS AND
VISIBILITIES FLUCTUATING THROUGHOUT THE NIGHT. TAF FORECAST WILL
BE CHALLENGING FOR THE COASTAL TERMINALS TODAY AS ONSHORE FLOW
STRENGTHENS IN ADVANCE OF A WEAK SURFACE FRONT SO STRATUS SHOULD
BE PRESENT TO SOME DEGREE ALONG THE IMMEDIATE COAST MUCH OF THE
DAY. WEAK SOUTHERLY COMPONENT TO THE WINDS AND COLDER AIR MOVING
IN ALOFT MAY FRAGMENT SOME OF THE STRATUS BUT IT WILL PROBABLY BE
RANDOM AND LIMITED. BURGER

&&

.MARINE...SEAS AND WINDS WILL REMAIN SUBDUED TODAY. LOW PRESSURE
TRAVERSING THE NORTH PACIFIC WILL INDUCE HIGHER SEAS WHICH WILL
FILTER INTO THE NORTHWEST CALIFORNIA WATERS TONIGHT. SMALL CRAFT
CONDITIONS...BOTH FOR SEAS AND WINDS...ARE LIKELY BY THURSDAY FOR
MOST OF THE WATERS AS HIGH PRESSURE BUILDS OVER THE NORTHEAST
PACIFIC. BURGER

&&

.EKA WATCHES/WARNINGS/ADVISORIES...NONE.
