AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
400 PM PDT SUN MAR 9 2014

.SYNOPSIS...MODERATE TO HEAVY RAIN WILL EXPAND SOUTHWARD ACROSS NORTHWEST
CALIFORNIA TONIGHT AS A FRONT SLOWLY PASSES THROUGH. AFTER SOME
LINGERING SHOWERS EARLY MONDAY...MUCH OF THE WEEK LOOKS DRY AND MILD
AS STRONG HIGH PRESSURE RETURNS.

&&

.DISCUSSION...
A BAND OF SHOWERS CONTINUE TO IMPACT NW CALIFORNIA BRINGING RAIN
TOTALS SINCE MIDNIGHT UP TO AROUND 0.15-0.50" ACROSS MENDOCINO,
0.50-2" ACROSS HUMBOLDT AND TRINITY, AND 2-4" ACROSS DEL NORTE
THIS AFTERNOON. THERE HAVE BEEN SEVERAL REPORTS OF ROCK SLIDES AS
AN IMPACT OF TODAY'S RAINFALL. RAINFALL RATES SHOULD CONTINUED TO
BE MONITORED THIS EVENING FOR THE POTENTIAL OF LOCALIZED URBAN AND
SMALL STREAM FLOODING AS MUCH OF THE REGION IS VERY SATURATED WITH
TODAY'S RAINFALL. RAIN SHOWERS WILL CONTINUE THROUGH THE NIGHT AS
THE SLOW MOVING FRONTAL BOUNDARY PROPAGATES TO THE SOUTHEAST
THROUGH MONDAY MORNING. THUNDERSTORMS ALONG THE ORCA BORDER WERE
OMITTED FROM THE FORECAST TONIGHT DUE TO UNFAVORABLE CONVECTIVE
PARAMETERS AS THE SHORTWAVE SLIDES OVER PACIFIC NW. IN ADDITION,
RECENT MODEL RUNS WERE INDICATING THE COLD POOL WOULD NOT DIP AS
FAR SOUTH AS PREVIOUSLY THOUGHT AND THEREFORE INSTABILITY
CONDUCIVE TO CONVECTIVE DEVELOPMENT WOULD NOT BE PRESENT.

CONDITIONS WILL BEGIN IMPROVING MONDAY AS RIDGING OCCURS BEHIND THE
FRONT. INCREASING STABILITY AND RESIDUAL MOISTURE WILL ALLOW THE
FORMATION OF PATCHY VALLEY FOG MONDAY AND TUESDAY NIGHT. OTHER
THAN THAT, MOSTLY CLEAR CONDITIONS ARE ANTICIPATED WITH MODELS
HINTING AT LOW RELATIVE HUMIDITY ACROSS MUCH OF THE NWCA THROUGH THE
REMAINDER OF THE WORK WEEK. THIS SIGNALS THE POTENTIAL FOR FROSTY
OVERNIGHT CONDITIONS POSSIBLY BY EARLY WEDNESDAY MORNING.

BY EARLY IN THE WEEKEND, A SHORTWAVE TROUGH WILL SLIDE
OVER BRITISH COLUMBIA CAUSING 500MB HEIGHTS TO FALL OVER NWCA. THE
BEST FORCING AND THEREFORE THE BEST POSSIBILITIES FOR RAIN WILL BE
RESTRICTED NORTHWARD ACROSS OREGON. AS A RESULT, UNMENTIONABLE POPS
WERE MAINTAINED THROUGH THE LATTER PORTION OF THE FORECAST. ALL IN
ALL, RIDGING WILL DOMINATE THE WEATHER PATTERN THROUGH THE THE
UPCOMING WEEK RESULTING IN A WARMING AND DRYING TREND. EXPECT
SUNSHINE AND INCREASINGLY WARM TEMPERATURES INLAND THROUGH THE
WEEK, POSSIBLY REACHING IN THE LOW 80S ACROSS INTERIOR VALLEYS BY
NEXT WEEKEND. KML

&&

.AVIATION...A COLD FRONT REMAINS DRAPED ACROSS THE REGION BRINGING
WIDESPREAD RAIN. THE RAIN HAS RESULTED IN REDUCED VISIBILITIES AND
CEILINGS. IFR AND LIFR CONDITIONS WILL PERSIST OVERNIGHT BEFORE
DRIER AIR FUNNELS IN BEHIND THE FRONTAL PASSAGE LATE TONIGHT. VFR
CONDITIONS WILL DEVELOP DURING THE MORNING HOURS ON MONDAY. RPA

&&

.MARINE...SWAN AND ENP MODEL GUIDANCE HAD BEEN ADAMANT THAT A
WESTERLY SWELL WOULD BUILD INTO THE WATERS TODAY ...AND IT FINALLY
ARRIVED SEVERAL HOURS LATER THAN PREDICTED. SEAS THIS AFTERNOON HAVE
PEAKED AT 10 TO 12 FEET AT 15 SECONDS AND WILL SUBSIDE OVERNIGHT.
HAVE EXTENDED THE SMALL CRAFTS THROUGH 3 AM...ABOUT 6 HOURS LATER
THAN ENP GUIDANCE WOULD SUGGEST THE SWELL WILL SUBSIDE TO MATCH UP
WITH THE LATER ARRIVAL OF THE SWELL. WINDS ARE NOW VERY LIGHT ACROSS
THE WATERS AND WILL TURN TO OUT OF THE NORTH OVERNIGHT INTO MONDAY
AS A COLD FRONT FINALLY SLIDES SOUTH OF THE AREA. SMALL CRAFT WINDS
ARE EXPECTED ACROSS THE OUTER WATERS LATER MONDAY INTO TUESDAY NIGHT
AS HIGH PRESSURE STRENGTHENS OVER THE EASTERN PACIFIC.

A WEAK UPPER LEVEL WAVE WILL ADVANCE INTO THE PACIFIC NORTHWEST
TUESDAY NIGHT SQUASHING THE WEST COAST RIDGE THAT DEVELOPS BEHIND
THE FRONTAL PASSAGE TONIGHT. THIS WILL RESULT IN MODERATE OFFSHORE
FLOW AND A WEAKENING OF THE PRESSURE GRADIENT OVER THE WATERS.
EXPECT WINDS TO BECOME FAIRLY LIGHT TUESDAY NIGHT INTO WEDNESDAY
BEFORE HIGH PRESSURE RE-ESTABLISHES ITSELF OVER THE EASTERN PACIFIC
BY THURSDAY. A VERY LONG PERIOD WESTERLY SWELL JUST HAPPENS TO BE
FORECAST TO BUILD INTO THE WATERS TUESDAY NIGHT INTO WEDNESDAY
BEGINNING AROUND 20 SECONDS AND BUILDING TO 8 TO 10 FEET AT 16
SECONDS ON WEDNESDAY. WITH NICE WEATHER AND THE POSSIBILITY OF
LITTLE SHORT PERIOD SEAS DUE TO THE OFFSHORE FLOW...A SNEAKER WAVE
THREAT MAY BE PRESENT ON WEDNESDAY AND THIS WILL BE INCLUDED IN THE
HWO. RPA

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...SMALL CRAFT ADVISORY UNTIL 3 AM PDT MONDAY PZZ450-455-470.

     SMALL CRAFT ADVISORY UNTIL 5 AM PDT WEDNESDAY PZZ475.
