AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
328 PM PST TUE DEC 6 2011

.SYNOPSIS...
MOSTLY CLEAR SKIES...CRISP MORNINGS AND PLEASANT AFTERNOONS WILL
CONTINUE AS HIGH PRESSURE PERSISTS OVER THE REGION THROUGH AT LEAST
THE END OF THIS WEEK.

&&

.DISCUSSION...
WE CAN EXPECT MORE DRY WEATHER AND SUNSHINE FOR THE FORESEEABLE
FUTURE AS BLOCKING HIGH PRESSURE REMAINS OVER THE NORTHEAST PACIFIC
HEADING THROUGH THE WEEKEND INTO NEXT WEEK. WE WILL SEE A COUPLE OF
MINOR DISTURBANCES PASSING BY WITH MOST OF THE ENERGY KEPT TO OUR
NORTHEAST...WITH UPPER LEVEL HIGH PRESSURE REESTABLISHING ITSELF
AFTER EACH DISTURBANCE PASSES BY. ONE SUCH DISTURBANCE WILL MOVE
THROUGH WED NT/THU MORNING WITH THE FLOW BECOMING MORE SOUTHERLY AND
WEAKLY ONSHORE AHEAD OF IT. THIS MAY ALLOW FOR SOME COASTAL LOW
CLOUDS WEDNESDAY NIGHT BUT NOT EXPECTING ANYTHING TOO EXTENSIVE WITH
LIMITED MOISTURE AROUND. DRIER AIR WILL QUICKLY BUILD BACK IN WITH
WEAK OFFSHORE FLOW BECOMING REESTABLISHED INTO THE WEEKEND. TRENDED
HIGH TEMPS WARMER THAN GUIDANCE AND LOWS LOWER THAN GUIDANCE GIVEN
THE BIAS WE HAVE BEEN SEEING OVER THE PAST WEEK. FROST WILL CONTINUE
TO OCCUR MOST LOCATIONS...BUT NOWHERE THAT HASNT ALREADY SEEN THE
GROWING SEASON COME TO AN END OVER THE PAST FEW DAYS. ANOTHER
DISTURBANCE WITH A BIT MORE DEPTH TO IT AND MORE TIME AND SPACE OVER
THE PACIFIC MAY BRING MORE CLOUDS IN SAT NT/SUN MORNING BUT THAT
LOOKS TO BE THE ONLY IMPACT AT THIS POINT. MAY HAVE SOME STRONGER NE
WINDS ALOFT IN ITS WAKE FOR SOME STRONGER WINDS ACROSS THE RIDGETOPS
MONDAY BUT THE SFC PRESSURE GRADIENT LOOKS RELATIVELY WEAK WITH THE
THERMAL TROUGH EXTENDING NORTHWARD ALONG THE NW CALIFORNIA COAST.

THERE ARE SOME SIGNS OF THE PATTERN BECOMING A BIT LESS AMPLIFIED
LATER NEXT WEEK. SOME ENERGY DROPPING SOUTHWARD ACROSS INTERIOR
CALIFORNIA MAY EVENTUALLY BEGIN RETROGRADING UNDERNEATH THE RIDGE.
THIS WILL STILL ALLOW AT LEAST AN EXTENSION OF HIGH PRESSURE TO
REMAIN OVER THE PACIFIC NORTHWEST WITH THE TENDENCY FOR OFFSHORE
FLOW TO REMAIN. THE GFS AND ITS ENSEMBLES HAVE BEEN LESS CONSISTENT
AND LESS TRUSTWORTHY IN TRYING TO BREAK DOWN THE PATTERN...SO UNTIL
WE SEE MORE CONSISTENCY AND MORE MODEL SUPPORT WE WILL KEEP THE
FORECAST UNSEASONABLY DRY WITH WELL BELOW CLIMO POPS...DESPITE THE
STANDARD LOWER CONFIDENCE HEADING FURTHER OUT IN TIME. LEFT THE
SLIGHT CHC POPS TUESDAY BUT WILL LIKELY NEED TO REMOVE THOSE AS
WELL. AAD

&&

.AVIATION...
VFR CONDITIONS WILL PERSIST OVERNIGHT AT THE TAF SITES. AN EDDY OF
LOW CLOUDS HAS FORMED OVER THE COASTAL WATERS TODAY AND MAY MOVE
TOWARD THE COAST LATER THIS EVENING AND OVERNIGHT AS WINDS INCREASE
OUT OF THE NORTH OVER THE WATERS. HOWEVER THE MOST LIKELY SCENARIO
IS FOR THESE CLOUDS TO STAY OUT OVER THE WATERS AND MOVE SOUTH SO
THE TAFS WILL MAINTAIN VFR. A FEW PATCHY AREAS OF VALLEY FOG WILL BE
POSSIBLY WEDNESDAY MORNING AWAY FROM THE TAF SITES. RPA

&&

.MARINE...
WINDS AND SEAS WILL REMAIN LOW OVERNIGHT BEFORE WINDS INCREASE OUT
OF THE NORTH...GREATEST ACROSS THE NORTHERN OUTER WATERS. THIS IS IN
RESPONSE TO LOWERING PRESSURE OVER LAND AS A WEAK UPPER LEVEL LOW
HOLDS OVER CENTRAL CALIFORNIA AND HIGH PRESSURE IS MAINTAINED OVER
THE NORTHEASTERN PACIFIC. AS THE HIGH WEAKENS THURSDAY NIGHT WINDS
WILL DECREASE ONCE AGAIN. FRESH SWELL FROM THESE NORTHERLY WINDS
WILL PROPAGATE SOUTH INTO THE SOUTHERN WATERS AND THUS SEAS HAVE
BEEN INCREASED THURSDAY INTO FRIDAY ACROSS THE SOUTHERN WATERS. ON
FRIDAY A NORTHWEST SWELL BEGINNING AROUND 20 SECONDS WILL BEGIN TO
ENTER THE WATERS BUILDING TO AROUND 8-9 FT AT 15 TO 16 SECONDS ON
SATURDAY. IF WIND DRIVEN SEAS SETTLE ENOUGH ON FRIDAY AS THE WINDS
DECREASE A SNEAKER WAVE THREAT MAY DEVELOP AS THE FORERUNNERS REACH
THE COAST. AT THIS POINT ENP/SWAN GUIDANCE INDICATES SEAS SHOULD
STILL BE UNSETTLED THUS REDUCING THE SNEAKER WAVE THREAT. THIS WILL
BE WATCHED CLOSELY AND IF CONDITIONS LOOK MORE FAVORABLE THE THREAT
WILL BE HIGHLIGHTED IN THE HWO. NORTHERLY WINDS WILL INCREASE ONCE
AGAIN EARLY NEXT WEEK AS AN UPPER LEVEL LOW DIVES SOUTH OVER
INTERIOR OREGON/IDAHO INTO THE GREAT BASIN AND THEN FINALLY THE
DESERT SOUTHWEST. RPA

&&

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