AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
225 PM PDT TUE MAR 31 2009

.SYNOPSIS...A WEAK WEATHER DISTURBANCE MAY BRING SOME DRIZZLE OR
VERY LIGHT RAIN PRIMARILY TO COASTAL SECTIONS NORTH OF CAPE
MENDOCINO TONIGHT...OTHERWISE DRY WEATHER CAN BE EXPECTED THROUGH
WEDNESDAY. A COLD FRONT WILL SWEEP ACROSS THE REGION LATE WEDNESDAY
NIGHT AND INTO THURSDAY...BRINGING COLDER WEATHER AND SHOWERS TO THE
REGION. DRIER AND WINDY WEATHER IS ON TAP AS HIGH PRESSURE BUILDS
OVER THE REGION LATE IN THE WEEK.

&&

.DISCUSSION...THE MAIN FORECAST CHALLENGES INVOLVE FRONTAL PASSAGE
EARLY THURSDAY AND ITS EFFECTS...THEN THE PATTERN LATE IN THE PERIOD.

A WEAK UPPER LEVEL DISTURBANCE CRUISING THROUGH THE PACIFIC
NORTHWEST OVERNIGHT WILL PROVIDE LITTLE MORE THAN A GLANCING BLOW TO
THE FORECAST AREA. WE HAVE RETAINED SLIGHT CHANCE POPS FOR COASTAL
SECTIONS NORTH OF CAPE MENDOCINO BUT THE ATMOSPHERE LOOKS RELATIVELY
DRY SO THE MORE LIKELY FORM IS DRIZZLE IF ANYTHING. A MORE
SIGNIFICANT SHORTWAVE WITH AN ASSOCIATED FRONTAL SYSTEM DROPS TOWARD
THE REGION WEDNESDAY NIGHT AND CROSSES THE REGION EARLY THURSDAY.
MORE MOISTURE ACCOMPANIED BY GREATER DYNAMICS WILL WARRANT LIKELY
POPS FOR NORTHERN SECTIONS LATE IN THE NIGHT THROUGH THURSDAY...WITH
PRECIPITATION PROSPECTS LINGERING INTO THURSDAY NIGHT. IMMEDIATELY
FOLLOWING THE FRONT MUCH COLDER AIR AND STRONGER WINDS WILL FILTER
INTO THE AREA...RESULTING IN SNOW LEVELS DROPPING TO AS LOW AS 2500
FEET BY THURSDAY NIGHT. DEPENDING ON HOW MUCH MOISTURE IS REMAINING
IN THE COLDER AIR MASS...A WINTER WEATHER ADVISORY MAY BE REQUIRED
BUT CONFIDENCE IN THIS IS NOT GREAT AT THIS POINT. THE OTHER
ISSUE...THE WINDS...WILL CERTAINLY BE A FACTOR BY FRIDAY AS STRONG
HIGH PRESSURE BUILDS OFFSHORE. THIS WILL BRING DRY WEATHER BUT
COASTAL ENVIRONS AND RIDGETOPS WILL EXPERIENCE GUSTS UP TO 40 MPH.

AFTER A DRY FIRST HALF OF THE WEEKEND...THE PATTERN BECOMES FAIRLY
AMBIGUOUS. WE HAVE BASICALLY SIDED WITH THE EURO/CANADIAN SUITE OVER
THE MORE PROGRESSIVE GFS AT THIS TIME...HOLDING OFF ON THE BEST
CHANCES FOR PRECIPITATION UNTIL SUNDAY NIGHT OR MONDAY. BURGER

&&

.AVIATION...A WEAK COLD FRONT IS APPROACHING THE COAST THIS
AFTERNOON.  THIS WILL SERVE MAINLY TWO PURPOSES...FIRST PROVIDING
MID TO HIGHER LEVEL CLOUDS AND THE POTENTIAL FOR LIGHT SHOWERS.
SECONDLY AND MORE OF AN IMPACT TO THE COAST SIDE TERMINALS WILL BE
ANOTHER PUSH OF MOIST ONSHORE FLOW ALLOWING LOWER STRATUS AND FOG
WITH WAS OFF THE COAST EARLIER IN THE DAY TO PUSH THROUGH AGAIN
LATER THIS AFTERNOON AND EVENING. MAINLY MVFR CONDITIONS WITH
PERIODS OF IFR POSSIBLE AT KCEC AND KACV AS WELL AS OTHER NEAR COAST
AIR SITES. WITH THE APPROACHING SYSTEM THE GUSTY NORTHERLIES WILL
DIMINISH AS THE PRESSURE GRADIENT WEAKENS.  INTERIOR SITES SHOULD
SEE AN INCREASE IN HIGHER LEVEL CLOUDS BUT SHOULD REMAIN VFR THROUGH
THE NEXT TAF CYCLE. JTON

&&

.MARINE...NORTHERLY WINDS ARE FINALLY DIMINISHING AS THE PRESSURE
GRADIENT WEAKENS DUE TO AN APPROACHING WEAK FRONT.  WINDS MAY TURN
WEST OR SOUTHWEST BRIEFLY TONIGHT AND THROUGH THE EARLY MORNING
HOURS BEFORE VEERING BACK TO THE NORTH BEHIND THE FRONT.  MODELS
CONTINUE TO DEPICT ANOTHER GUSTY NORTHWESTERLY WIND SURGE BEHIND THE
FRONT THURSDAY EVENING WITH GALE FORCE GUSTS THROUGH FRI EVENING.
LATEST GUIDANCE MAY HAVE DROPPED THE MAGNITUDE OF WIND DURING THIS
TIME FRAME THUS HAVE OPTED TO REMAIN GALE WATCH FREE (FOR NOW).  NW
SWELL WILL ALSO ARRIVE INTO THE REGION AROUND THE SAME TIME
GENERATED BY THE NORTHERN END OF THE SYSTEM IN THE GULF OF ALASKA.
BOTH THE SWAN RUNS AND THE ENP INDICATE SWELL BUILDING TO NEAR 15
FT...WHICH IN COMBINATION WITH THE STEEP WIND DRIVEN WAVES WILL LEAD
TO COMBINED SEAS APPROACHING 18-20FT. JTON
