252 PM PDT SUN MAR 28 2010

.SYNOPSIS...A STRONG STORM SYSTEM WILL PUSH INTO THE REGION
TONIGHT AND MONDAY...RESULTING IN BLUSTERY CONDITIONS AND PERIODS
OF HEAVY RAIN. A COOLER AIRMASS WILL MOVE INTO THE REGION FOR
TUESDAY AND WEDNESDAY AS A TROUGH DEEPENS OVERHEAD. HIGH
ELEVATION SNOW IS EXPECTED TUESDAY AND TUESDAY NIGHT AS
TEMPERATURES COOL.

&&

.DISCUSSION...MAIN FORECAST CHALLENGES REMAIN QPF...SNOW
LEVELS...AND CONVECTION THROUGH MID WEEK. CURRENT SURFACE
ANALYSIS DEPICTS TIGHTENING PRESSURE GRADIENT THIS
AFTERNOON...RESULTING IN INCREASING SOUTHERLY WINDS...WITH HIGH
PRESSURE OFF TO THE SOUTHEAST. WEAKENING TRAILING TROUGH THAT
CONTINUES TO BRING LIGHT RAIN TO THE NORTHERN PORTIONS OF THE
FORECAST AREA THIS AFTERNOON WILL DIMINISH IN STRENGTH THIS
EVENING PER WARMING CLOUDS ON IR SATELLITE IMAGERY...AND EXITING
OF MAIN SHORT WAVE TO THE NNE WELL INTO BRITISH COLUMBIA.
ELONGATED VORTICITY MAX AS SEEN ON WATER VAPOR IMAGERY THIS
AFTERNOON AS STRIP OF RELATIVE DRYNESS NORTH OF 40N BETWEEN 130
AND 150W...AND EMBEDDED IMPULSES WILL BE THE MAIN SOURCES OF LIFT
FOR THE PRECIP EXPECTED MONDAY. WINDS WILL INCREASE TONIGHT INTO
MONDAY MORNING...ESPECIALLY ACROSS REDWOOD COAST NEAR CRESCENT
CITY...AS 55+ KT LOW LEVEL JET DEVELOPS. STRONG UPPER JET STREAK
AROUND BASE OF LONG WAVE TROUGH WILL NOSE QUICKLY OVER THE PAC NW
STARTING TONIGHT...PROVIDING ENHANCED LIFT TO THE
REGION...INCLUDING NW CA. PWATS PER 12Z GFS CLIMB TO OVER AN INCH
MONDAY THANKS TO LONG WSW FETCH...WITH MAIN MOISTURE AXIS FOCUSED
PARTIALLY ON NORTHERN CA. WARM COLUMN IN PLACE SHOULD RESULT IN
PERIODS OF HEAVY RAIN MONDAY AS A RESULT...WITH HEAVIEST PRECIP
ACROSS THE NORTHERN ZONES.

TUESDAY...COLUMN TEMPERATURES COOL QUICKLY AS UPPER LONG WAVE
TROUGH DIGS ACROSS THE WEST COAST. COLD AIR ADVECTION WILL SET IN
AS H85 TEMPERATURES DROP TO -3 TO -5C BY WEDNESDAY MORNING.
MOISTURE AXIS WILL STILL BE NEAR TUESDAY AS UPPER IMPULSES
INTERACT WITH THE MAIN BAROCLINIC ZONE. SNOW LEVELS WILL DROP TO
NEAR 2KFT BY TUESDAY EVENING...LIKELY RESULTING IN SOME
SIGNIFICANT ACCUMULATIONS ABOVE 2500 FT. WILL MONITOR FOR POSSIBLE
SNOW ADVISORY FOR TUESDAY/TUESDAY NIGHT. IN ADDITION...COLD AIR
ALOFT WILL RESULT IN CAPE VALUES UP TO 500 J/KG...MAINLY OVER THE
WARMER WATERS AND COASTAL AREAS TUESDAY.

WILL BE WELL INTO THE COOLER AIRMASS BY WEDNESDAY...WITH
INSTABILITY SHOWERS CONTINUING THROUGH THE DAY. CONVECTIVE
INSTABILITY AXIS DOES PUSH INLAND WEDNESDAY ACROSS MUCH OF
MENDOCINO COUNTY. HAVE INTRODUCED ISOLATED THUNDER
ACCORDINGLY...AND ADDED MENTION OF SMALL HAIL WITH COLD AIRMASS IN
PLACE. TOTAL QPF THROUGH WED AFTERNOON LOOKS TO BE 1 TO 3 INCHES
ACROSS THE CWA...WITH 3 TO 5 INCHES IN HIGHER ELEVATIONS AND
FAVORED AREAS.

WEDNESDAY NIGHT/THURSDAY...MODELS DIFFER ON THE TRACK AND TIMING
OF MORE SIGNIFICANT SHORT WAVE TO DIVING SOUTH ALONG THE
CALIFORNIAN COAST ON THE BACKSIDE OF THE UPPER TROUGH. GEM REMAINS
FARTHER OFFSHORE THAN GFS/ECMWF. LOOKS LIKE MAIN BULK OF PRECIP
MAY REMAIN OFFSHORE THROUGH THURSDAY MORNING...BUT MAY STILL
PRODUCE SOME HIGHER ELEVATION SNOWFALL OVER THE REGION.

BRIEF UPPER RIDGING LOOKS TO BUILD OVERHEAD FOR THE LATTER HALF
OF THURSDAY/THURS NIGHT. EXTENDED MODELS REMAIN
INCONSISTENT...HOWEVER A WET...LONG WAVE TROUGH REGIME LOOKS TO
SET UP AGAIN FOR NEXT WEEKEND. HENRY

.AVIATION...PERSISTENT MVFR CONDITIONS HAVE BEEN PRESENT MOST OF
THE DAY AT KCEC WHILE CONDITIONS WERE A LITTLE BETTER SOUTH ALONG
THE COAST AS A MILD WEATHER FEATURE MOVED ACROSS THE REGION. WITH
WEAK ONSHORE MOIST FLOW DO NOT ANTICIPATE MUCH CHANGE THROUGH THE
EVENING FOR THE COAST OR THE INTERIOR. LATER TONIGHT ANOTHER FRONT
WILL MOVE ACROSS THE COAST WHICH MAY ACTUALLY IMPROVE CONDITIONS
AT KCEC BUT WILL BE ACCOMPANIED BY GUSTIER SOUTH WINDS. SOME LIGHT
CHOP CAN BE EXPECTED AS WELL DURING THE EARLY MORNING HOURS DUE
THE TO NON CONVECTIVE SHEAR WITHIN THE VICINITY OF KACV. INTERIOR
LOCATIONS MAY SEE BRIEF PERIODS OF MVFR CONDITIONS DUE MAINLY TO
LOWER CIGS TONIGHT AND TOMORROW.

&&

.MARINE...GALES CAN BE EXPECTED OVER THE NORTHERN OUTER WATERS LATE
THIS EVENING BEFORE SPREADING INTO THE INNER ZONE OVERNIGHT. A SHORT
PERIOD WIND SEA WILL BUILD ON TOP OF A BUILDING SWELL BEGINNING
EARLY MONDAY MORNING THUS WARRANTING THE ISSUANCE OF A HAZ SEAS
WARNING FOR THE NRN WATERS BEGINNING MIDNIGHT TONIGHT. THE LARGE
FETCH REGION OF HIGH GALE TO STORM FORCE WINDS WILL PROMOTE THE GROWTH
OF A LARGE LONGER PERIOD SWELL WHICH WILL BUILD TO NEAR 22 FT AT 13
TO 15 SECONDS BY TUE. THIS LARGE SWELL TRAIN WILL PERSIST INTO WED
BEFORE GRADUALLY DIMINISHING BELOW WARNING CRITERIA.
