AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
150 PM PST THU MAR 5 2009

.SYNOPSIS...A WEAK SYSTEM WILL BRING A FEW LIGHT SHOWERS TO THE
REGION OVERNIGHT...ESPECIALLY NORTH OF CAPE MENDOCINO. DRY WEATHER
IS EXPECTED TOMORROW AFTERNOON THROUGH SATURDAY NIGHT...BEFORE
ANOTHER WEAK SYSTEM BRINGS A RENEWED CHANCE FOR SHOWERS. DRY AND
WARMER WEATHER CAN BE ANTICIPATED FOR EARLY NEXT WEEK.

&&

.DISCUSSION...A WEAK SYSTEM WILL RACE THROUGH THE AREA
OVERNIGHT...BRINGING PERIODS OF LIGHT RAIN AND HIGH ELEVATION SNOW
BUT PRECIPITATION TOTALS WILL GENERALLY AMOUNT TO NO MORE THAN A
QUARTER INCH IF EVEN THAT. ABOVE 2500 FEET ELEVATION...AN INCH OR
TWO OF NEW SNOW IS POSSIBLE GENERALLY NORTH OF CAPE MENDOCINO.

A DRY DAY IS EXPECTED FOR THE MOST PART TOMORROW...ALTHOUGH A SHOWER
OR TWO MAY LINGER DURING THE MORNING HOURS. CLOUDS WILL DECREASE AND
IT SHOULD BE A MILD DAY ALTHOUGH A BIT BREEZY ALONG THE COAST IN THE
AFTERNOON. SATURDAY WILL BE QUITE SIMILAR...BUT WITH A COLDER AND
PERHAPS FROSTY START TO THE MORNING. SEVERAL UPPER LEVEL
DISTURBANCES WILL CARVE OUT A DEEP TROUGH OVER THE GREAT BASIN...AND
ONE OF THESE DISTURBANCES MAY BE CLOSE ENOUGH TO US TO GENERATE A
FEW SHOWERS SUNDAY INTO EARLY MONDAY. HOWEVER...MODELS HAVE NOT
BEEN WHOLLY CONSISTENT ON THIS. IN ANY EVENT...PRECIPITATION
AMOUNTS WITH THIS SYSTEM WILL BE LIGHT. MEDIUM RANGE SOLUTIONS
KEEP WEAK CYCLONIC FLOW OR FLAT RIDGING OVER THE AREA FOR MOST OF
NEXT WEEK...SO WE KEPT POPS BELOW CLIMATOLOGY. THE PATTERN
LOOKS LIKE A TYPICAL SPRINGTIME ONE...WITH MAINLY DRY
WEATHER...CONSIDERABLE SUNSHINE ALONG THE COAST...COOL MORNINGS
AND BREEZY AFTERNOONS. BURGER

&&

.AVIATION...WEAK FRONT MOVING INTO THE PAC NW WILL BRING
DETERIORATING FLIGHT CONDITIONS TONIGHT THROUGH FRIDAY
MORNING...PRIMARILY ALONG THE COASTS AND COASTAL MOUNTAINS OF DEL
NORTE AND HUMBOLDT COUNTIES. VFR CEILINGS ARE EXPECTED THROUGH MUCH
OF THE EVENING...BUT MVFR CONDITIONS WILL CREEP INTO THE PICTURE AS
LIGHT RAIN DEVELOPS BY MID EVENING IN DEL NORTE COUNTY. THE MVFR
CONDITIONS IN LIGHT RAIN SHOULD SPREAD SOUTHWARD AFTER MIDNIGHT.
HARD TO SAY IF CEILINGS AND VSBYS WILL DROP INTO THE IFR OR LOW IFR
CATEGORY BY FRIDAY MORNING. TYPICALLY SATURATED CONDITIONS BELOW
3KFT AND IFR CONDITIONS FOLLOW IN THE NORTHWEST AND NORTHERLY
FLOW...AS THE OFFSHORE RIDGE BUILDS. NO GUARANTEES HERE...BUT WOULD
NOT BE TOO SURPRISED TO SEE AT LEAST BRIEF IFR CIGS AND VSBYS EARLY
FRIDAY MORNING. DJB

&&

.MARINE...LIGHT WINDS AND LOW SEAS WILL CONTINUE ACROSS THE WATERS
TONIGHT THROUGH FRIDAY MORNING...AS A WEAK FRONT MOVES INTO THE
PACIFIC NORTHWEST. NORTH WINDS WILL START TO RAMP UP AS EARLY AS
FRIDAY NIGHT...AS HIGH PRES BUILDS TOWARDS THE CALIFORNIA COAST
BEHIND THE FRONT. NORTH WINDS WILL STRENGTHEN SAT THROUGH SUN AND
RESULT IN SMALL CRAFT ADVISORY CONDITIONS THROUGH MON. WINDS SHOULD
GUSTS TO 35 KT IN THE OUTER WATERS SAT NIGHT AND SUNDAY. IT LOOKS TO
BE MARGINAL AT BEST DUE TO THE SHORT DURATION OF GUSTS TO 35 KT...
VERSUS SAY ONE OR TWO HOURS...WITH GUSTS OF 40-50 KT. THEREFORE
...WILL INDICATE ONLY A FEW GUSTS TO 35 KT AT THIS TIME AND HOLD OFF
ON INSERTING GALE HEADLINES INTO THE FORECAST. A STORM SYSTEM IN THE
WEST PACIFIC WILL CREATE A LONG PERIOD WNW SWELL...17-21 SECONDS.
THIS SWELL SHOULD ARRIVE INTO NW CA WATERS NEXT MON AND TUE. DJB

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