AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
423 AM PST TUE MAR 1 2016

.SYNOPSIS...A COLD FRONT IS APPROACHING THE COAST THIS MORNING
AND WILL BRING GUSTY WINDS AND RAIN TO THE REGION LATER TODAY.
AFTER A MOSTLY DRY DAY WEDNESDAY A SERIES OF WEATHER SYSTEMS WILL
BRING GUSTY WINDS AND PERIODS OF RAIN THROUGH THE WEEKEND.

&&

.DISCUSSION...PICS FROM SPACE THIS MORNING SHOW A DRY SLOT IN
BETWEEN YESTERDAYS WARM FRONT AND THE INSUING COLD FRONT STILL
OUT OFF THE COAST. THE COLD FRONT IS EXPECTED REACH THE COAST
LATE THIS MORNING ACCOMPANIED BY A BRIEF PERIOD OF HEAVIER RAIN
TO THE AREA AND GUSTY WINDS TO THE COAST.  GUSTS TO 40 MPH ARE
POSSIBLE IN THE EXPOSED AREAS. RAIN AND SOME HIGH ELEVATION WINDS
WILL CONTINUE TO TRECK EASTWARD DURING THE AFTERNOON. ISOLATED
THUNDERSTORMS ARE POSSIBLE WITH FRONTAL PASSAGE AT THE COAST NORTH
OF CAPE MENDOCINO. FORECAST MODELS ARE IN GOOD AGREEMENT ON
RAINFALL RANGING FROM OVER INCH IN DEL NORTE COUNTY TO LESS THAN A
TENTH OF INCH IN MENDOCINO COUNTY. TUESDAY NIGHT SHOWERS WILL
DIMINISH AND SOME PARTIAL CLEARING IS EXPECTED. TEMPERATURES WILL
DROP A BIT DUE TO THE CLEARING SKIES...BUT FROST IS NOT EXPECTED
AT THE COAST. WEDNESDAY MORNING A WEAK WARM FRONT WILL BRING SOME
CLOUDS AND A FEW SPRINKLES TO THE AREA...BUT MAINLY DRY CONDITIONS
ARE EXPECTED THROUGH MID AFTERNOON. THE 18Z GFS CAME IN SLIGHTLY
STRONGER WITH THIS WARM FRONT SO THIS WILL NEED TO BE WATCHED AS
IT GETS CLOSER. LATE WEDNESDAY AFTERNOON AND WEDNESDAY NIGHT THE
NEXT COLD FRONT IS EXPECTED TO IMPACT THE AREA. RAINFALL AMOUNTS
OF UP TO AN INCH ARE POSSIBLE IN THE TERRAIN FAVORED AREAS WITH
LESS ELSEWHERE. GUSTY WINDS ARE EXPECTED AT THE COAST AS WELL.
MK/JT

.PREVIOUS LONG TERM (FRIDAY THROUGH MONDAY)...LONG WAVE TROUGHING
OVER THE EASTERN PACIFIC WILL ALLOW SHORT WAVES TO MOVE ONTO THE
WEST COAST THROUGH THE LONG TERM...SETTING UP AN ACTIVE WEATHER
PATTERN. MODELS PROG SHOWERS MOVING ONTO THE COAST FRIDAY AND
SATURDAY AS A STATIONARY BOUNDARY EMBEDDED IN A MOIST SOUTHWEST
MEAN FLOW SETS UP OVER THE AREA. LATER IN THE WEEKEND...A MORE
SUBSTANTIAL STORM SYSTEM IS PROGGED TO MOVE THROUGH THE AREA. THIS
SYSTEM HAS THE POTENTIAL TO BRING INCREASING SOUTHERLY
WINDS...PERIODS OF HEAVY RAIN...AND MOUNTAIN SNOW. AS THIS SYSTEM
IS ALMOST 7 DAYS OUT IN TIME...DETAILS WILL LIKELY CHANGE.
TEMPERATURES IN THE LONG TERM ARE EXPECTED TO BE NEAR TO SLIGHTLY
BELOW NORMAL. STP

&&

.AVIATION...CONDITIONS WILL DETERIORATE THROUGH THE DAY AS A
COLD FRONT MOVES THROUGH THE REGION. CEILINGS WILL GRADUALLY LOWER
AND SOUTHERLY WINDS WILL INCREASE ALONG THE COAST THIS MORNING...AND
RAIN WILL DEVELOP THIS MORNING AND PERSIST THROUGH THE MIDDLE OF THE
AFTERNOON. IFR CIGS/VSBYS WILL BE POSSIBLE FOR A FEW HOURS LATE
MORNING WHEN PRECIPITATION IS EXPECTED TO BE HEAVIEST ALONG THE
COAST. RAIN IS EXPECTED TO REACH UKI DURING THE AFTERNOON AND LAST
FOR A FEW HOURS AS WELL...BUT CEILING/VSBY REDUCTIONS AND WINDS ARE
NOT EXPECTED TO BE QUITE AS SIGNIFICANT. WINDS WILL DECREASE QUICKLY
BEHIND THE FRONT. SOME GROUND FOG AND LOW STRATUS WILL BE POSSIBLE
TOMORROW NIGHT AT ALL TERMINALS.  /BRC

&&

.MARINE...SOUTHERLY WINDS HAVE BEGUN TO INCREASE ACROSS THE
WATERS THIS MORNING AS A COLD FRONT APPROACHES NORTHWEST
CALIFORNIA. THE MOST RECENT ASCAT PASS THROUGH OUR WATERS AT AROUND
0600Z REVEALS A SWATH OF 25 TO 30 KT SUSTAINED WINDS APPROACHING THE
WATERS FROM THE WEST...WHICH IS CONSISTENT WITH RECENT HIGH
RESOLUTION MODEL DATA. THUS...WINDS ARE EXPECTED TO CONTINUE TO
INCREASE THROUGH THE MORNING AND AFTERNOON...REACHING SUSTAINED
SPEEDS OF AROUND 25 TO 30 KT WITH FREQUENT GUSTS TO 35 OR 40 KT FOR
AT LEAST A FEW HOURS ACROSS THE NORTHERN WATERS. IN ADDITION TO
THESE AMBIENT WINDS...A FEW STRONGER GUSTS MAY BE ABLE TO MIX DOWN
TO THE SURFACE FOR A BRIEF PERIOD RIGHT ALONG THE FRONTAL
BOUNDARY...PARTICULARLY IF ANY STRONGER SQUALLS CAN MANAGE TO
DEVELOP. A GALE WARNING HAS BEEN ADDED FOR THE NORTHERN INNER WATERS
IN ADDITION TO THE ALREADY EXISTING WARNING FOR THE NORTHERN
OUTERS...AS THESE STRONG WINDS WILL LIKELY REACH EXPOSED AREAS
AROUND HEADLANDS SUCH AS POINT SAINT GEORGE AND CAPE MENDOCINO AND
THE VERY LEAST. WIDESPREAD GALE FORCE WINDS MAY NOT OCCUR AROUND
MORE SHELTERED AREAS LIKE HUMBOLDT BAY...HOWEVER EVEN IN THOSE
AREAS BRIEF PERIODS OF GALES WILL BE POSSIBLE WITH ANY SQUALLS THAT
DEVELOP RIGHT ALONG THE FRONT. THESE STRONG WINDS WILL CAUSE STEEP
SHORT PERIOD SEAS TO INCREASE IN ADDITION TO THE CONTINUING WESTERLY
SWELL. ACROSS THE WATERS SOUTH OF CAPE MENDOCINO...WINDS AND SEAS
WILL INCREASE AS WELL BUT ARE NOT EXPECTED TO BE AS SEVERE AS THEY
WILL BE FARTHER NORTH. THUS...THE SMALL CRAFT ADVISORIES WILL
CONTINUE. WINDS WILL DECREASE QUICKLY IN ALL WATERS LATE IN THE
AFTERNOON AS THE COLD FRONT MOVES ONSHORE.

THROUGH THE REMAINDER OF THE WEEK...THE SEA STATE WILL REMAIN
ELEVATED AT BEST...AND HAZARDOUS AT WORST AS A SERIES OF STORM
SYSTEMS MOVE THROUGH THE WATERS. THESE STORMS WILL RESULT IN
PERIODS OF SOUTHERLY GALES AND BUILDING STEEP SEAS...WHICH WILL
OCCUR IN ADDITION TO A BUILDING WESTERLY SWELL. /BRC
