AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
140 PM PDT FRI OCT 22 2010

.SYNOPSIS...A COUPLE OF PACIFIC STORMS WILL BRING PERIODS OF RAIN TO
NW CA TONIGHT THROUGH SUNDAY. THE RAIN SATURDAY NIGHT THROUGH SUNDAY
MORNING WILL BE HEAVY AT TIMES.

&&

.DISCUSSION...SATELLITE IMAGERY SHOWS THE NEXT PACIFIC STORM RIGHT
OFF THE OREGON AND CA COASTS. THIS STORM IS MORE ORGANIZED THAN THE
ONE THAT BROUGHT LIGHT RAIN TO THE REGION THU NIGHT...WITH AN
ESTIMATED 982MB LOW POSITIONED NEAR 44N 138W. THE FRONT EDGE OF THE
CLOUD BAND ASSOCIATED WITH THE FRONT IS CURRENTLY 125 MILES OFFSHORE
OF CAPE MENDOCINO. SOUTH WINDS WILL BECOME GUSTY THIS EVENING AS THE
FRONT APPROACHES. ALTHOUGH THERE MAY BE SOME LIGHT RAIN AHEAD OF THE
FRONT THIS EVENING THE BULK OF THE RAIN WILL BEGIN AROUND MIDNIGHT.
RAINFALL TOTALS WILL GENERALLY BE BETWEEN 0.25 AND 0.5 INCH TONIGHT
THROUGH FRIDAY MORNING WITH LOCALLY HIGHER AMOUNTS. THE RAIN WILL
TURN TO SHOWERS IN THE AFTERNOON JUST BEFORE RAIN FROM THE NEXT MORE
POTENT STORM REACHES THE COAST.

THE NEXT STORM WILL TAP INTO AN EXTREMELY MOIST SUBTROPICAL PLUME AS
IT MOVES ACROSS THE PACIFIC TOWARDS CALIFORNIA. THE KEY ATMOSPHERIC
INGREDIENTS ARE IN PLACE FOR A SIGNIFICANT RAINFALL EVENT AS A 180+KT
JET ROUNDS THE BASE OF A DEEP LOW PRESSURE SYSTEM OFF THE QUEEN
CHARLOTTE ISLANDS. THE LOW ASSOCIATED WITH THIS FRONT WILL BE DEEPER
THAN THE STORM EXPECTED TONIGHT...AND THE GUSTY SOUTH WINDS WILL BE
MORE NOTICEABLE...ALTHOUGH SHOULD REMAIN BELOW ADVISORY. THERE IS
STILL SOME UNCERTAINTY OF THE TIMING OF WHEN THE RAIN WILL
BEGIN...BUT CURRENT FORECAST IS FOR HEAVY RAIN TO BEGIN BETWEEN 10
PM AND MIDNIGHT SATURDAY. EXPECT WIDESPREAD 2 TO 4 INCHES WITH SAT
NIGHT INTO SUN MORNING WITH 5 TO 7 INCHES POSSIBLE FOR OROGRAPHIC
FAVORED AREAS. THE MAIN IMPACTS OF THE RAIN WILL BE PONDING ON THE
ROADS AND MINOR STREET FLOODING...ESPECIALLY WHERE FALLING LEAVES
HAVE CLOGGED DRAINS AND CULVERTS. THE MAINSTEM RIVERS WILL RISE
RAPIDLY...ESPECIALLY THE SMITH RIVER...BUT WILL REMAIN BELOW MONITOR
STAGE.

COLD AIR WILL MOVE IN BEHIND THE FRONT SUNDAY NIGHT AND THE HIGHER
ELEVATIONS...6 TO 7 KFT WILL GET A LIGHT DUSTING OF SNOW. SNOW
LEVELS MAY DROP DOWN TO 4500 FEET MONDAY NIGHT AS 700MB TEMPERATURES
ARE FORECASTED TO DROP TO AROUND -8C. HOWEVER...THE RAIN SHOULD
TAPER OFF BY THIS TIME AND DO NOT ANTICIPATE MUCH IF ANY SNOW AT OR
BELOW THE PASSES.

MODELS STILL HINT AT AN UPPER LEVEL RIDGE BUILDING ACROSS THE REGION
TUE AND WED...ALTHOUGH A MOIST ONSHORE WINDS MAY CONTINUE TO TAP
INTO RESIDUAL TROPICAL MOISTURE AND CONTINUE TO GENERATE OCCASIONAL
SHOWERS ACROSS THE REGION. ANOTHER SYSTEM IS EXPECTED NEAR THE END
OF THE WEEK AND HAVE INCREASED POPS WELL ABOVE CLIMO FOR THU AND
FRI. TH

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL LATE THIS
AFTERNOON AND EVENING...HOWEVER CONDITIONS WILL DETERIORATE TO MVFR
OVERNIGHT AS A FRONT PUSHES THROUGH THE REGION. LOW LEVEL WIND SHEAR
OF RAPIDLY INCREASING SPEED WITH HEIGHT UP TO 40 KT WILL ALSO LIKELY
BE PRESENT THIS EVENING ALONG THE REDWOOD COAST DUE TO A LOW LEVEL
JET. LIGHT RAIN WILL ACCOMPANY THE FRONTAL PASSAGE THROUGH EARLY
SATURDAY. CONDITIONS ARE THEN EXPECTED TO IMPROVE TO VFR BY MIDDAY
SATURDAY BEFORE THE SLUG OF HEAVY RAIN PUSHES IN SATURDAY NIGHT.
HENRY

&&

.MARINE...SOUTHERLY WINDS WILL INCREASE RAPIDLY LATE THIS EVENING
AND OVERNIGHT AS THE NEXT FRONTAL SYSTEM APPROACHES. NEAR GALE FORCE
CONDITIONS ARE EXPECTED ACROSS THE NORTHERN OUTER WATERS TONIGHT.
WINDS WILL SUBSIDE JUST A BIT SATURDAY...BUT THEN INCREASE RAPIDLY
AGAIN FOR SATURDAY EVENING. GALE FORCE WINDS LOOK LIKELY FOR THE
NORTHERN OUTER WATERS AND HAVE ISSUED A WARNING ACCORDINGLY. GALE
FORCE GUSTS CAN BE EXPECTED ELSEWHERE. THE ASSOCIATED LARGE SWELL
FOLLOWING THESE STORMS LOOKS TO AFFECT THE WATERS SUNDAY NIGHT AND
MONDAY...AND IS PROGGED TO PEAK AROUND 20 TO 21 FT AT 15 SECONDS.

WATCH FOR THIS LARGE NORTHWEST SWELL. A HIGH SURF ADVISORY MAY ALSO
BE NEEDED FOR SUNDAY NIGHT AND MONDAY...AND WILL MONITOR AS TIME
