AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
445 AM PST THU JAN 7 2016

.SYNOPSIS...A SERIES OF OFFSHORE LOW PRESSURE SYSTEMS AND
FRONTAL BOUNDARIES WILL PRODUCE PERIODS OF RAIN...HIGH ELEVATION
SNOW...AND GUSTY SOUTHERLY WINDS THROUGH NEXT WEEK. BREAKS IN
PRECIPITATION ARE EXPECTED EARLY FRIDAY...SUNDAY...AND TUESDAY.

&&

.DISCUSSION...LIGHT SHOWER ACTIVITY CONTINUES TO GRADUALLY
DIMINISH THROUGHOUT THE AREA THIS MORNING...ALTHOUGH A FEW SHOWERS
REMAIN JUST OFF THE REDWOOD COAST AS OF 4 AM. A FEW STATIONS
ACROSS THE EASTERN PARTS OF TRINITY COUNTY CONTINUE TO RECORD VERY
LIGHT PRECIPITATION AS WELL...LIKELY OWING TO PERSISTENT MOIST
SOUTHERLY FLOW BEING FORCED OVER THE EASTERN SLOPES OF THE KLAMATH
MOUNTAINS. THROUGH THE REMAINDER OF THE DAY A GRADUAL DOWNWARD
TREND IN PRECIPITATION COVERAGE IS EXPECTED...AND MOST AREAS WILL
REMAIN DRY WITH PERHAPS EVEN A FEW BREAKS IN THE CLOUDS BY EARLY
AFTERNOON. BY LATE AFTERNOON AND EVENING...ANOTHER BATCH OF LIGHT
RAIN IS EXPECTED AS THE LAST REMNANTS OF AN UPPER LOW MOVE
ONSHORE. THIS IS LOW IS CURRENTLY VISIBLE ON SATELLITE JUST OFF
THE OREGON COAST...AND WHILE PREVIOUS MODEL RUNS HAVE TAKEN THIS
LOW SOUTH OF CAPE MENDOCINO...RECENT MODEL TRENDS ALONG WITH
SATELLITE OBSERVATIONS INDICATE THAT THE REDWOOD COAST AND
ADJACENT INTERIOR AREAS WILL BE THE FOCUS FOR PRECIPITATION
INSTEAD. SNOW LEVELS ARE EXPECTED TO INCREASE SLIGHTLY FROM
CURRENT LEVELS TO AROUND 4000 FEET AHEAD OF THIS LOW...ALTHOUGH
SOME OF THE INTERIOR VALLEYS OF TRINITY COUNTY MAY SEE SNOW LEVELS
FALL TO THE VALLEY FLOOR OVERNIGHT. IN ANY CASE...WHEREVER SNOW
DOES FALL IT WILL BE LIGHT AND NOT LIKELY TO REACH ADVISORY
CRITERIA.

BEYOND TODAY...THE ACTIVE AND PROGRESSIVE PATTERN THAT WE
CURRENTLY FIND OURSELVES IN WILL CONTINUE WITH NO SIGNS OF
STOPPING OVER THE NEXT WEEK OR SO. AS SUCH...A SERIES OF FAST
MOVING STORM SYSTEMS WILL BRING REGULAR EPISODES OF MODERATE
PRECIPITATION AND BREEZY SOUTHEASTERLY WINDS PUNCTUATED BY COOL
AND DRY PERIODS. THE FIRST OF THESE SYSTEMS WILL BRING MORE
PRECIPITATION TO THE REGION LATE FRIDAY THROUGH SATURDAY AFTER A
SHORT BREAK FROM THE RAIN. A SLIGHTLY MORE SUBSTANTIAL RIDGE WILL
RESULT IN DRY CONDITIONS SUNDAY AND SUNDAY NIGHT...HOWEVER
ADDITIONAL STORMS WILL BRING MORE RAIN MONDAY AND WEDNESDAY. THESE
STORMS HAVE MANY SIMILAR CHARACTERISTICS AS THE ONES THAT HAVE
PASSED THROUGH THE AREA RECENTLY...AND HEAVIEST PRECIPITATION WILL
LIKELY CONTINUE TO BE FOCUSED SOUTH OF CAPE MENDOCINO.
FORTUNATELY...EVEN THOUGH WE ARE IN A WET AND ACTIVE PATTERN...THE
FAST MOVING NATURE OF THESE SYSTEMS WILL LIKELY PREVENT HEAVY RAIN
FROM FALLING IN ANY ONE PLACE FOR VERY LONG...WHICH IS EXPECTED TO
MITIGATE THE FLOODING THREAT WHILE PROVIDING BENEFICIAL RAINS. AS
FOR SNOW...WHILE HIGH ELEVATION PEAKS WILL CONTINUE TO SEE
SNOW...THESE SYSTEMS DO NOT APPEAR TO BE PARTICULARLY COLD AND
SNOW LEVELS WILL LIKELY REMAIN ABOVE THE MAJORITY OF OUR AREA
PASSES ASIDE FROM POSSIBLY THE HIGHER PASSES OF 36. /BRC

&&

.AVIATION...MAIN ISSUES WILL CENTER AROUND SHOWER ACTIVITY AND
THE POTENTIAL OF GROUND FOG ACROSS INTERIOR SITES FOR THE NEXT TAF
CYCLE. ISOLATED TO SCATTERED SHOWERS ARE EXPECTED ACROSS MUCH OF
THE REGION TODAY FOLLOWED BY MORE WIDESPREAD AND CONSISTENT
RAINFALL NORTH OF HWY 36 TONIGHT AS A WEEK FRONT MOVES THROUGH.
THERE IS POTENTIAL FOR SOME PATCHY IFR TYPE FOG AROUND THE
INTERIOR VALLEYS THIS MORNING BUT IT WILL BE VERY LOCALIZED AND
BRIEF. OTHERWISE SOME MAINLY VFR FOR THE REMAINDER OF TODAY WITH
THE EXCEPTION OF BRIEF PERIODS OF MVFR DUE TO SHOWERS.

&&

.MARINE...THE SEA STATE HAS INCREASED OVER THE LAST SEVERAL HOURS
AS ANOTHER SWELL PROPAGATES THE COASTAL WATERS. CURRENT SWELL
HEIGHTS ARE RUNNING 16 TO 19 FT THIS MORNING. THE HAZARDOUS SEAS
WARNING WILL REMAIN IN EFFECT THROUGH LATER THIS MORNING...AND WILL
HAVE TO BE REASSESSED TO SEE WHETHER IT CAN BE TAKEN DOWN OR EXTENDED
A LITTLE LONGER.  ALTHOUGH WAVE HEIGHTS MAY FALL OUT OF WARNING
CATEGORY THEY WILL REMAIN ELEVATED THROUGH MUCH OF THE DAY BEFORE
DIMINISHING LATER THIS EVENING AND THROUGH FRIDAY. SEAS WILL REMAIN
AROUND 8 TO 12 FT THROUGH THE WEEKEND. GENTLE TO MODERATE WINDS WILL
BECOME VARIABLE THROUGH EARLY THURSDAY AS LOW PRESSURE MOVES TO THE
EAST. THEN EXPECT SOUTHERLY FLOW TO RETURN FRIDAY AS ANOTHER LOW
PRESSURE SYSTEM APPROACHES THE REGION.

.BEACH HAZARDS...A HIGH SURF ADVISORY CONTINUES FOR THE COASTAL
WATERS AS A LARGE SWELL WITH BREAKERS AROUND 20 TO 24 FT
PROPAGATES ACROSS THE NORTHWEST CALIFORNIA BEACHES TODAY. THIS
THREAT WILL DIMINISH THIS EVENING THROUGH THE WEEKEND AS THE LARGE
SWELL SUBSIDES. COASTAL FLOODING WILL ALSO BE PRESENT DUE TO HIGH
TIDES OVER THE NEXT SEVERAL MORNINGS. THUS A COASTAL FLOOD
ADVISORY IS IN EFFECT THIS MORNING AND WILL LIKELY BE NEEDED FOR
FRIDAY MORNING TOO AS THE PREDICTED TIDE WILL BE HIGHER PROMOTING
NUISANCE FLOODING AROUND HUMBOLDT BAY. HIGHER ASTRONOMICAL TIDES
ARE PREDICTED THROUGH THE WEEKEND.

PREDICTED HIGH TIDES AT THE NORTH SPIT TIDE GAUGE...
THURSDAY: 7.45 FT AT 9:17 AM
FRIDAY: 7.68 FT AT 9:57 AM
SATURDAY: 7.84 FT AT 10:38 AM
SUNDAY: 7.91 FT AT 11:19 AM
