AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
352 PM PDT MON OCT 31 2011

.SYNOPSIS...
DRY WEATHER WILL PERSIST ON TUESDAY AS ROBUST OFFSHORE FLOW DEVELOPS
AND HOLDS THROUGH WEDNESDAY MORNING. A FRONT WILL APPROACH THE COAST
LATE ON WEDNESDAY...BRINGING A CHANCE OF RAIN AND MOUNTAIN SNOW BY
THURSDAY MORNING.

&&

.DISCUSSION...
IN THE WAKE OF A COLD FRONT BUT AHEAD OF A SHORTWAVE TROUGH
NORTHWEST CALIFORNIA HAS BEGUN TO EXPERIENCE THE INFLUENCE OF
INCREASINGLY DRIER AIR. AFTER CLEARING OCCURRED THIS MORNING ONLY AN
AREA OF STRATOCU LINGERED OVER THE HIGHER TERRAIN OF HUMBOLDT
COUNTY. ELSEWHERE SKIES ARE CLEAR INCLUDING WELL OFFSHORE...AND THIS
WILL CONTINUE TO BE THE TREND TONIGHT INTO TUESDAY DESPITE A RATHER
SHARP SHORTWAVE TROUGH PASSING BY. HEIGHTS WILL BUILD IN THE WAKE OF
THE TROUGH ALLOWING A THERMAL TROUGH TO STRENGTHEN AND PUSH OFFSHORE
OF THE CALIFORNIA COAST BY TUESDAY AFTERNOON. SEE THE FIRE WEATHER
DISCUSSION BELOW. OFFSHORE FLOW WILL KEEP CLEAR SKIES IN PLACE
THROUGH WEDNESDAY. WILL NEED TO MONITOR LOW TEMPERATURES THE NEXT
COUPLE OF NIGHTS AS FROST WILL BE POSSIBLE ALL THE WAY TO NEAR
COASTAL AREAS ESPECIALLY WEDNESDAY MORNING. NORTHEAST WINDS WILL
STAY UP TUESDAY NIGHT BUT IN SHELTERED AREAS FREEZING TEMPERATURES
WILL BE A POSSIBILITY. LOOKING AHEAD TO THE NEXT SYSTEM...MODELS
HAVE SLOWED DOWN TIMING A BIT BUT STILL LOOKS LIKE A WEDNESDAY NIGHT
ARRIVAL. UPPER LOW WILL BRING SNOW LEVELS DOWN TO 3500FT OR UNDER
LATE THURSDAY AS SHOWERS GRADUALLY TAPER OFF HEADING INTO THURSDAY
NIGHT. LIQUID AMOUNTS OF ONE HALF INCH TO AN INCH LOOK POSSIBLE BUT
MUCH OF THIS WILL OCCUR BEFORE THE SNOW LEVELS COME DOWN. FRIDAY IS
LOOKING LIKE A DRY DAY...MIGHT NOT BE A BAD IDEA TO TAKE OUT POPS
COMPLETELY FRIDAY INTO FRIDAY NIGHT. TIMING OF THE NEXT SYSTEM
SATURDAY NIGHT STILL LOOKS QUESTIONABLE BUT RAISED POPS TO LIKELY
SATURDAY NIGHT. MAY SEE ANOTHER BREAK ON SUNDAY BUT OTHERWISE THE
ACTIVE PATTERN LOOKS TO CONTINUE INTO NEXT WEEK.

&&

.FIRE WEATHER...
DECIDED TO CANCEL THE FIRE WEATHER WATCH FOR A COUPLE REASONS.
COORDINATED WITH THE GACC IN REDDING THAT FUELS ACROSS MOST OF THE
AREA ARE NOT CONDUCIVE TO SUSTAINED BURNING WHERE CONDITIONS WOULD
BE CLOSE TO RFW CRITERIA. ADDITIONALLY...WINDS ACROSS MENDOCINO
COUNTY ARE NOT EXPECTED TO BE AS HIGH AS ORIGINALLY THOUGHT...MORE
IN THE 10 TO 15 MPH RANGE AS OPPOSED TO 15 TO 25 AND GUSTY. RH
VALUES WILL STILL BE LOW AND ANY AREAS OF STRONGER WINDS WHICH DO
MIX DOWN WILL BE A HAZARD. HOWEVER...WITH WINDS EXPECTED TO ABATE
WEDNESDAY MORNING AND TURN ONSHORE WEDNESDAY AFTERNOON...AND COLD
AND WET CONDITIONS EXPECTED TO ARRIVE WEDNESDAY NIGHT AND
THURSDAY...THE THREAT WILL BE BRIEF AND LOCALIZED.

&&

.AVIATION...DRIER AIR BEHIND THE COLD FRONT WILL PROMOTE WIDESPREAD
VFR CONDITIONS THROUGH THE NEXT TAF CYCLE. GUSTY NORTHERLY WINDS WILL
PERSIST THROUGH THE EARLY EVENING HOURS ALONG THE COASTAL TERMINALS.

&&

.MARINE...GALES IN FULL FORCE ACROSS THE OUTER WATERS WITH A FEW
GUSTS TO NEAR 35KT REPORTED BY THE INNER WATER BUOYS EARLY THIS
AFTERNOON. THE GRADIENT WILL CONTINUE TO INCREASE FOR THE NEXT SEVERAL
HOURS HOWEVER THE NEAR COAST WINDS WILL LIKELY DECOUPLE A BIT AFTER
MIDNIGHT THEN REGAIN STRENGTH LATE TOMORROW MORNING. STEEP SHORT PERIOD
SEAS WILL PERSIST THROUGH THE NEXT 36 HOURS.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
GALE WARNING PZZ470...PZZ475
HAZ SEAS WARNING PZZ450...PZZ455
