AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
201 PM PST MON FEB 1 2010

.SYNOPSIS...A WEAKENING COLD FRONT WILL RESULT IN DIMINISHING
SHOWERS ACROSS NORTHWEST CALIFORNIA TONIGHT. LIGHT RAIN SHOWERS
WILL CONTINUE THROUGH WEDNESDAY AS AN UPPER LOW SLOWLY MOVES
OVERHEAD. A COUPLE OF STRONGER WINTER STORM SYSTEMS WILL AFFECT THE
REGION LATE THIS WEEK AND WEEKEND.

&&

.DISCUSSION...MAIN UPPER LOW NOW LOCATED IN LAT/LON GRID EAST AND
NORTH OF 140W AND 40N RESPECTIVELY PER LATEST WATER VAPOR
IMAGERY...ALONG WITH SEVERAL SHORT WAVE IMPULSES ROUNDING THE
BASE AND LIFTING NORTHEAST TOWARD THE PAC NW COAST. ONE AREA OF
DRYING NOW LIFTING ACROSS THE NORTH COAST...IS BRINGING AN END TO
MORE WIDESPREAD PRECIP. STILL EXPECT SHOWER ACTIVITY TO CONTINUE
TONIGHT UNDER UNSETTLED TROUGH PATTERN...BUT ALSO CONTINUE TO
DIMINISH IN COVERAGE. A MORE POTENT VORT MAX RESULTS IN SHARPENED
TROUGH FEATURE WITH MAIN UPPER LOW BECOMING NEGATIVELY TILTED AND
LIFTING NORTHEAST OVER NORCAL AND PAC NW. THIS TILTING AND
PLACEMENT RESULTS IN COLD POOL ALOFT AND DECREASED STABILITY. HAVE
MAINTAINED MENTION OF ISOLATED THUNDER ACROSS THE WATERS
ACCORDINGLY...AND HAVE EXPANDED AREAS TO INCLUDED THE REDWOOD
COAST AND CAPE MENDOCINO. OVERALL QPF AMOUNTS DO NOT LOOK TOO
IMPRESSIVE...ESPECIALLY FOR WINTER WITH GENERALLY UP TO AN
ADDITIONAL QUARTER TO HALF AN INCH POSSIBLE THROUGH MID WEEK. HAVE
RECEIVED A REPORT OF BRIEF LIGHT SNOW AT 3800 FT AT IRON PEAK THIS
AFTERNOON. HAVE LOWERED SNOW LEVELS A BIT WITH THIS INFORMATION
HOWEVER ACCUMULATING SNOW STILL SHOULD BE HIGH ENOUGH TO NOT
CAUSE ANY MAJOR CONCERNS FOR PASSES.

STRONGER AND DEEPER LOW WILL THEN MOVE INTO THE NORTHEAST PACIFIC
FOR THE LATTER HALF OF THE WEEK AND WEEKEND. A COUPLE OF SIGNIFICANT
SHORT WAVES WILL ROUND THIS LOW AND AFFECT THE REGION...WITH TIMING
LOOKING LIKE THURSDAY/THURS NIGHT AND FRIDAY NIGHT/SATURDAY. THE
THURSDAY SYSTEM IS THE MORE DYNAMIC SYSTEM...WITH STRONG AND GUSTY
SOUTHERLY WINDS AND PERIODS OF HEAVY RAIN POSSIBLE. AFTER A BRIEF
BREAK FRIDAY...SECONDARY SHORT WAVE WILL LIFT THROUGH FRIDAY NIGHT
AND SATURDAY. WINDS LOOKS TO NOT BE QUITE AS STRONG WITH THIS
SYSTEM. COULD HAVE SOME SIGNIFICANT SNOW ACCUMULATIONS ABOVE 4KFT
WITH THESE STORMS...AND HAVE HIGHLIGHTED THIS THREAT IN THE HWOEKA.
NOTHING OUT OF THE ORDINARY FOR THIS TIME OF YEAR LOOKS TO OCCUR WITH
THESE SYSTEMS AT THIS TIME. HENRY

&&

.AVIATION...COLD FRONT APPROACHING THE WEST COAST IS FORECAST TO
WEAKEN AND STALL AS IT APPROACHES THE COAST. THIS WILL BRING
CONTINUED -RA AND VCSH TO MUCH OF THE AREA THROUGH THE FORECAST
PERIOD. COASTAL AREAS ARE EXPECTED TO REMAIN UNDER VFR CONDITIONS
UNDER A LIGHT OFFSHORE GRADIENT. INTERIOR VALLEYS WILL HAVE LOWERING
CIGS AND VSBY...WITH MVFR TO IFR EXPECTED BY LATE TONIGHT INTO EARLY
TUESDAY MORNING. CC

&&

.MARINE...MODERATE SOUTHERLY WINDS CONTINUE OVER THE WATERS THIS
AFTERNOON...WITH SCA WINDS OVER THE OUTER WATERS. EXPECT THIS TO
CONTINUE THROUGH THIS EVENING. MEANWHILE A WEST SWELL WILL BUILD
INTO THE WATERS...PEAKING NEAR 11 FT AT 14 SECONDS ON TUESDAY. LOW
PRESSURE OFFSHORE WILL MAINTAIN S WINDS THROUGH MIDWEEK. A STRONGER
STORM SYSTEM IS FORECAST TO APPROACH THE COAST ON THURSDAY...WITH
SOUTHERLY GALES AND BUILDING SEAS SUPPORTED BY MODEL SOLUTIONS WITH
FAIRLY GOOD AGREEMENT. A LONG PERIOD W SWELL WILL COMBINE WITH A
SHORTER PERIOD S-SW SWELL FORMED BY THE OFFSHORE LOW...CREATING A
DANGEROUS MIXED SEA STATE. WINDS WILL REMAIN NEAR OR JUST BELOW GALE
FORCE THROUGH FRIDAY. CC

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...
     SMALL CRAFT ADVISORY UNTIL 2 PM PST THIS AFTERNOON PZZ450.
