AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
352 PM PDT THU AUG 13 2015

.SYNOPSIS...LOW PRESSURE WILL LIFT OUT OF THE AREA TONIGHT
ALLOWING FOR HIGH PRESSURE TO BUILD IN FROM THE DESERT SOUTHWEST.
THIS WILL BRING A WARMING AND DRYING TREND FOR THE WEEKEND.

&&

.DISCUSSION...AFTERNOON SATELLITE SHOWS LOW PRESSURE STRAIGHT OFF
OF CAPE MENDOCINO, SLOWLY LIFTING OUT TO THE NORTH-NORTHEAST. AS
THIS LOW DEPARTS IT WILL PULL A WEAK TROUGH ACROSS DEL NORTE AND
NORTHERN HUMBOLDT COUNTIES, WHICH HAS A VERY OUTSIDE SHOT OF
TRIGGERING A SHOWER. THE BEST CHANCE IS UP OVER DEL NORTE, SO HAVE
PULLED THE POPS BACK TO SOLELY INCLUDE DEL NORTE. THIS WILL NEED
TO BE WATCHED THROUGH THE EVENING TO SEE HOW THE LOW TRANSITS AND
IF ANY CONVECTION DEVELOPS, WHICH IS NOT LIKELY. WINDS WILL
GENERALLY REMAIN OUT OF THE SOUTH AHEAD OF THE TROUGH, BUT VEER TO
THE WEST AND NORTHWEST BEHIND ITS PASSAGE. AREAS OF LOW PRESSURE
LIKE THIS TYPICALLY BRING ENOUGH LIFT ALONG THE COAST TO CAUSE
SOME DRIZZLE, SO HAVE ADDED PERIODS OF DRIZZLE TO THE IMMEDIATE
COAST OF NW CAL.

FRIDAY WILL BEGIN THE WARMING AND DRYING TREND FOR NW CAL, AWAY
FROM THE IMMEDIATE COAST, AS AN UPPER RIDGE NOSES IN FROM THE
DESERT SW. THIS WILL INDUCE A SURFACE THERMAL TROUGH AS THE LAND
HEATS UP DURING THE DAY. IN THE OVERNIGHT HOURS THIS THERMAL
TROUGH WILL DRIFT OFF THE COAST, CAUSING WINDS TO BECOME NE.
MODELS SHOW OFFSHORE WINDS REMAINING LIGHT, BUT WILL BEAR WATCHING
SINCE UNDER NE FLOW, COASTAL AREAS MAY HEAT UP MORE THAN FORECAST.
THIS WILL ONLY BE A TWO DAY TREND, AS THE RIDGE NOSING PULLS BACK
TO THE DESERT SW SUNDAY EVENING DUE TO AN UPPER TROUGH DIGGING
FROM THE PAC NW. THIS WILL HELP TO DEEPEN THE MARINE LAYER WITH
ONSHORE FLOW. NO RAIN IS EXPECTED AT THIS TIME WITH THIS TROUGH.

MODELS ARE SHOWING A RIDGE DEVELOPING OVER THE AREA FOR THE SECOND
HALF OF NEXT WEEK, WHICH WILL BRING A WARM UP. THE RIDGE WILL BE
NOSING IN FROM THE SW, SO TEMPS WILL BE LIMITED SLIGHTLY DUE TO
MORE OF A MARINE INFLUENCE. BFG

&&

.AVIATION...A BROAD AREA OF SHALLOW STRATUS HAS MOVED IN AND OUT
OF THE COASTAL SITES THROUGH THE DAY TODAY...BUT IT APPEARS THAT
MIXING HAS FINALLY CLEARED OUT THE TERMINALS FOR THE TIME BEING,
ALTHOUGH IT REMAINS VERY CLOSE TO SHORE. THIS EVENING IT WILL
LIKELY BE QUICK TO RETURN, BRINGING IN IFR TO PERIODIC LIFR
CEILINGS WITH POSSIBLE FOG/MIST VISIBILITY REDUCTIONS LATE EVENING
INTO THE OVERNIGHT HOURS. LATE INTO THE NIGHT/EARLY TOMORROW
MORNING, A PASSING LOW PRESSURE SYSTEM WILL DEEPEN THE MARINE
LAYER AND DRIVE STRATUS FARTHER INLAND, LIKELY RESULTING IN
GRADUALLY LIFTING CEILINGS AND POSSIBLY PERIODS OF DRIZZLE. CLOUDS
WILL LIKELY SCATTER OUT BY THE EARLY AFTERNOON TOMORROW, REVEALING
VFR CIGS FOR THE REMAINDER OF THE DAY. VFR CIGS ARE MOST LIKELY AT
UKI THROUGH THE NIGHT...BUT THE DEEPENING MARINE LAYER MAY BRING A
FEW LOW CLOUDS INTO THE VALLEY EARLY IN THE MORNING. BRC

&&

.MARINE...BUOYS CONTINUE TO INDICATE MIXED AND VERY LOW SEAS
THROUGHOUT THE WATERS THIS AFTERNOON..WITH WAVE HEIGHTS GENERALLY
AROUND 2 TO 3 FEET THROUGHOUT THE WATERS. THIS IS DUE TO
PERSISTENT VERY LIGHT WINDS THAT HAVE BEEN PRESENT FOR THE PAST
FEW DAYS...AS A NEARLY STATIONARY LOW PRESSURE SYSTEM HAS
MAINTAINED A WEAK PRESSURE GRADIENT THROUGHOUT OUR COASTAL WATERS.
THIS WILL CONTINUE THROUGH THE NIGHT TONIGHT...BUT CHANGES ARE ON
THE WAY AS THIS LOW BEGINS TO MOVE OUT OF THE AREA OVERNIGHT AND
FRIDAY AND ALLOW THE PACIFIC HIGH TO STRENGTHEN AND BUILD TOWARDS
THE COAST. IN THE NEAR TERM...THIS LOW MAY BE ENOUGH TO TRIGGER A
FEW SHOWERS AND POSSIBLY AN ISOLATED THUNDERSTORM OR TWO ACROSS
PRIMARILY THE NORTHERN OUTER WATERS TONIGHT. HOWEVER...THE BIGGER
IMPACTS WILL BEGIN TOMORROW... AS THE INTERACTION BETWEEN THE HIGH
AND A THERMAL TROUGH ACROSS THE INTERIOR WILL STRENGTHEN THE
PRESSURE GRADIENT...LEADING TO INCREASING NORTHERLY WINDS AND
BUILDING SHORT PERIOD SEAS. THERE REMAIN SOME MINOR DIFFERENCES
BETWEEN THE MODELS OVER HOW QUICKLY WINDS WILL INCREASE ON FRIDAY.
SINCE MOST OF THE MODELS SHOW HIGHER WINDS ON FRIDAY...LEANED
TOWARDS THAT IN THIS FORECAST. BY SATURDAY THE MODELS SEEM TO BE
IN GOOD AGREEMENT REGARDING THE WIND STRENGTH. EXPECT NORTHERLY
NEAR GALES WITH GUSTS TO GALE FORCE...ESPECIALLY ACROSS THE
NORTHERN OUTER WATERS. THESE WINDS WILL GENERATE VERY STEEP
HAZARDOUS SEAS IN THE OUTER WATERS. WINDS WONT BE AS STRONG ACROSS
THE INNER WATERS. THOUGH...A NORTHERLY STRONG BREEZE IS LIKELY.
ADDITIONALLY...STEEP FRESH SWELL GENERATED ACROSS THE OUTER WATERS
WILL PROPAGATE INTO THE INNER WATERS. EXPECT THESE CONDITIONS THIS
WEEKEND INTO EARLY NEXT WEEK. BRC/MS

&&

.FIRE WEATHER...AN UPPER LOW OFF THE NORTHWEST CALIFORNIA COAST
WILL MOVE NORTHEAST TONIGHT THROUGH FRIDAY BRINGING THE POTENTIAL
FOR SOME SHOWERS OVER PORTIONS OF NORTHWEST CALIFORNIA THIS
EVENING. ANY SHOWERS THAT FORM WILL BE LIGHT WITH WETTING RAINS
VERY UNLIKELY. MODELS GENERALLY KEEP THIS ACTIVITY CONFINED TO DEL
NORTE COUNTY AND NORTH. AN UPPER LEVEL RIDGE WILL BUILD INTO
CALIFORNIA BEHIND THE UPPER LOW ALLOWING THE THERMAL TROUGH TO RE-
ESTABLISH ITSELF OVER INTERIOR CALIFORNIA. THIS WILL RESULT IN
WARMING TEMPERATURES AND OFFSHORE FLOW OVER DEL NORTE, NORTHERN
HUMBOLDT, AND WESTERN SISKIYOU COUNTIES OVER THE WEEKEND.
OVERNIGHT RECOVERIES WILL BECOME POORER THAN WHAT HAS BEEN
OCCURRING RECENTLY, BUT STILL AT THIS TIME APPEARS TO NOT BE LOW
ENOUGH WITH 6 TO 12 MPH EAST-NORTHEASTERLY WINDS TO JUSTIFY ANY
SORT OF WATCH OR WARNING. HOWEVER, MAINTAINED THE HEADLINE IN THE
FIRE WEATHER FORECAST AND WILL CONTINUE TO MONITOR MODELS CLOSELY
FOR POTENTIALLY DRIER CONDITIONS DURING THE OVERNIGHT PERIODS.

A SHORTWAVE TROUGH WILL BRING A BRIEF PERIOD OF NEAR NORMAL TEMPS
EARLY NEXT WEEK BEFORE THE ANOTHER RIDGE ESTABLISHES ITSELF OVER
NW CAL RESULTING IN DRY AND HOT CONDITIONS FOR THE SECONDS HALF OF
NEXT WEEK. RPA/BFG

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...NONE.
