AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
256 PM PDT MON MAR 9 2015

.SYNOPSIS...HIGH PRESSURE WILL MAINTAIN DRY WEATHER AND ABOVE
NORMAL HIGH TEMPERATURES IN THE INTERIOR...WHILE PERSISTENT
LOW CLOUDS WILL KEEP TEMPERATURES COOL ALONG THE COAST THROUGH
EARLY TUESDAY. A FRONTAL SYSTEM WILL BRING A CHANCE OF RAIN
TUESDAY AND WEDNESDAY.

&&

.DISCUSSION...TUESDAY THE UPPER RIDGE FINALLY BEGINS TO SLIDE
EASTWARD TOWARDS THE GREAT BASIN. AS THIS OCCURS...NORTH WINDS
WILL GIVE WAY TO SOUTHERLY FLOW...WHICH WILL GRADUALLY ERODE THE
MARINE LAYER AND ITS ASSOCIATED STRATUS/FOG. HOWEVER...INCREASING
HIGHER LEVEL CLOUD COVER ASSOCIATED WITH AN APPROACHING STORM
SYSTEM IS LIKELY TO REPLACE IT...SO THOSE ALONG THE COAST AREN'T
LIKELY TO SEE MUCH SUN FOR THE FORESEEABLE FUTURE. OF MORE
IMPORTANCE...THOUGH...WILL BE INCREASING CHANCES FOR RAIN WITH
THIS SYSTEM...AND THERE REMAINS A BIT OF UNCERTAINTY REGARDING
JUST HOW THIS EVENT WILL EVOLVE. MODELS HAVE BEEN RELATIVELY
CONSISTENT OVER THE PAST SEVERAL RUNS IN PORTRAYING A SUBTLE LEAD
IMPULSE REACHING THE COAST OVERNIGHT TUESDAY...BUT CONTINUE TO
DIFFER REGARDING JUST HOW QUICKLY THE ATMOSPHERE WILL MOISTEN
DURING THIS TIME PERIOD. IN ANY CASE...IT APPEARS THAT THE MOST
LIKELY AREA TO SEE MEASURABLE PRECIPITATION EARLY ON IN THE EVENT
WILL BE HIGHER ELEVATIONS OF THE INTERIOR LATE TUESDAY/EARLY
WEDNESDAY...WITH ONLY VERY LIGHT AMOUNTS EXPECTED ELSEWHERE. LATER
IN THE DAY WEDNESDAY...THE PRIMARY TROUGH AND A DECAYING SURFACE
FRONT WILL MOVE ONSHORE...BRINGING WITH IT MUCH DEEPER MOISTURE
AND A PERIOD OF MORE SUBSTANTIAL RAIN. MODEL GUIDANCE APPEARS TO
BE SLOWLY DRIFTING TOWARDS A CONSENSUS BUT REMAINS HIGHLY VARIED
REGARDING PRECIPITATION COVERAGE AND AMOUNTS. HOWEVER...IT DOES
CONTINUE TO APPEAR THAT THE HEAVIEST TOTALS ARE LIKELY TO BE
OBSERVED NORTH OF THE CAPE...ALTHOUGH CONFIDENCE IS INCREASING
THAT MENDOCINO COUNTY WILL SEE AT LEAST SOME LIGHT PRECIPITATION
AS WELL. WHILE RAIN RATES MAY BE HEAVY AT TIMES...PARTICULARLY IN
ANY CONVECTIVE ELEMENTS THAT DEVELOP LATE IN THE DAY...THE RAPID
PASSAGE OF THIS WAVE WILL LIMIT THE DURATION OF THE HEAVIEST
RAINFALL...KEEPING TOTALS GENERALLY BELOW ANY MAJOR IMPACTS. SNOW
LEVELS ARE EXPECTED TO DROP TO AROUND 6500 FEET AS WELL...WHICH
SHOULD BE LOW ENOUGH FOR THE HIGHER PEAKS IN THE TRINITY ALPS TO
SEE SOME LIGHT ACCUMULATIONS WHILE KEEPING AREA PASSES CLEAR.

BY THURSDAY MORNING MOST OF THE RAIN SHOULD CEASE AS AN UPPER RIDGE
WILL QUICKLY REGAIN ITS HOLD ON THE WEST COAST...ALBEIT NOT FOR
LONG. HAVE ADDED SOME PATCHY FOG MENTION TO THE INTERIOR VALLEYS
FRIDAY MORNING...ALTHOUGH THIS WILL LIKELY HINGE ON JUST HOW MUCH
RAIN FALLS IN THE INTERIOR ON WEDNESDAY.  TEMPERATURES ARE ALSO
EXPECTED TO CLIMB UPWARDS YET AGAIN THROUGH THE END OF THE
WEEK...AND BY THE WEEKEND ATTENTION TURNS TO ANOTHER APPROACHING
FRONTAL SYSTEM.  MODELS CONTINUE TO HOLD ON TO THEIR RESPECTIVE
BIASES REGARDING THIS NEXT SYSTEM...WITH THE GFS VERY QUICK TO BRING
IN A ROUND OF RAINFALL LATE SATURDAY/EARLY SUNDAY.  WITH THE ECMWF
STILL LAGGING BEHIND AND AGREEMENT LACKING...NO MAJOR CHANGES MADE
TO THE WEEKEND FORECAST FOR NOW.

&&

.AVIATION...LOW CLOUDS AND PATCHY FOG WILL CONTINUE ALONG THE NW
CA COAST. THIS CLOUD MASS WILL REMAIN THRU THE TAF PERIOD...
ERODING SLIGHTLY ON THE INLAND SIDE DURING THE LATE MORNING AND
AFTERNOON ONLY TO SPREAD BACK INLAND IN THE EVENING. SOME
IMPROVEMENT IS EXPECTED TOWARD SUNRISE AS SOUTHERLY WINDS HELP MIX
OUT THE LOWER LEVELS AND ALLOW CIGS TO RISE AT THE COASTAL SITES.
VFR CONDITIONS CONTINUE AT KUKI...WITH LOW CLOUDS AS FAR INLAND AS
THE ANDERSON VALLEY. LIGHT WINDS WILL PERSIST.

&&

.MARINE...WINDS AND SEAS WILL REMAIN GENERALLY LIGHT NORTHERLY
THRU THE LATE EVENING. WINDS WILL BECOME S EARLY TUE AND INCREASE
TUE NIGHT INTO WED AS LOW PRESSURE DEEPENS WELL NW OF THE AREA.
THIS WILL LIKELY BRING SMALL CRAFT ADVISORY CONDITIONS TO THE N
OFFSHORE ZONE ON WED. NW SWELL WILL CONTINUE THRU THE EARLY PART
OF THE WEEK WITH PERIODS OF AROUND 14 SECONDS TODAY BECOMING 12
SECONDS BY TUE. LONG PERIOD S SWELL WILL ARRIVE BY WED NIGHT WITH
PERIODS STARTING AT AROUND 20 SECONDS. THIS SWELL IS FORECAST TO
REMAIN BETWEEN 1 AND 2 FEET.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...

CA...NONE.

NORTHWEST CALIFORNIA COASTAL WATERS...NONE.
