AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
400 PM PST FRI DEC 19 2008

.SYNOPSIS...SHOWERS WILL CONTINUE TO DIMINISH TONIGHT AS THE FIRST
IN A SERIES OF STORMS EXITS THE REGION. ANOTHER SYSTEM WILL CROSS
THE PACIFIC NORTHWEST ON SATURDAY...BRINGING ADDITIONAL RAIN AND
SNOW ALONG WITH GUSTY SOUTH WINDS TO THE AREA LATE SATURDAY THROUGH
SUNDAY. A THIRD STORM IS FORECAST TO AFFECT THE REGION TUESDAY...AND
IS LIKELY TO AFFECT HOLIDAY TRAVEL WITH RAIN...SNOW AND BLUSTERY
WINDS.
&&

.SHORT TERM...TONIGHT THROUGH MONDAY...A RELATIVE LULL IN THE
WEATHER PATTERN WILL CONTINUE TONIGHT AND INTO EARLY SATURDAY. A FEW
HIGH CLOUDS IN ADVANCE OF THE NEXT SYSTEM WILL SPILL OVER THE REGION
TONIGHT...BUT WILL NOT PREVENT A COLDER NIGHT WITH MOST LOCATIONS
FALLING TO AROUND FREEZING OR BELOW. THE NEXT WEATHER
EVENT...CURRENTLY TAKING SHAPE IN THE GULF OF ALASKA...WILL
INTENSIFY TOMORROW WITH MID LEVEL MOISTURE OVERRUNNING AN
APPROACHING WARM FRONT. THUS...CLOUDS WILL INCREASE DURING THE DAY
WITH LIGHT STRATIFORM PRECIPITATION DEVELOPING MAINLY ALONG THE
COAST NORTH OF THE CAPE DURING THE AFTERNOON. IF PRECIPITATION MAKES
IT FAR ENOUGH EAST TO IMPACT TRINITY COUNTY LATE SATURDAY...SOME
LIGHT SNOW IS POSSIBLE ON THE VALLEY FLOORS BUT WE ARE NOT EXPECTING
ANY ACCUMULATION. SNOW LEVELS SHOULD RECOVER TO AT LEAST 4000 TO
4500 FEET BY THE TIME PRECIPITATION BECOMES HEAVIER ON SUNDAY...WITH
MODEL FORECAST SOUNDINGS OVER TRINITY COUNTY ALSO SUPPORTING ONLY
RAIN ALONG THE VALLEY BOTTOMS. IN FACT...SNOW LEVELS MAY REACH 6000
FEET DEPENDING ON HOW MUCH WARM AIR ADVECTION OCCURS AHEAD OF THE
COLD FRONT BUT THIS IS STILL A MATTER OF UNCERTAINTY. IN ANY
EVENT...SOUTHERLY WINDS WILL INCREASE SATURDAY NIGHT THROUGH EARLY
SUNDAY IN ADVANCE OF THE COLD FRONT WITH SUSTAINED WINDS OF 25 TO 35
MPH ALONG THE COAST NORTH OF THE CAPE. SOME GUSTS MAY REACH 50 MPH
ALONG EXPOSED COASTAL HEADLANDS AND ALSO OVER THE RIDGES DURING
THIS TIME FRAME. SNOW LEVELS WILL FALL BACK TO THE 2000 TO 3000 FOOT
RANGE SUNDAY NIGHT INTO EARLY MONDAY BUT PRECIPITATION WILL BECOME
LESS ORGANIZED BY THEN. STILL...SOME ACCUMULATING SNOWS ARE
POSSIBLE. CURRENT PRECIPITATION ESTIMATES FOR THE ENTIRE EVENT RANGE
FROM ABOUT ONE HALF INCH IN SOUTHERN MENDOCINO COUNTY TO A COUPLE OF
INCHES IN DEL NORTE COUNTY. BURGER

.LONG TERM...MONDAY EVENING THROUGH FRIDAY...SHOWERS WILL DISSIPATE
THROUGH THE DAY MON BEFORE ANOTHER STORM SYSTEM APPROACHES THE
REGION. IN ADDITION TO RAIN...THIS STORM WILL PRODUCE STRONG SOUTH
WINDS ACROSS MUCH OF THE CWA TUE NIGHT AND WED. MODELS REMAIN IN
FAIR AGREEMENT WITH THE SYNOPTIC PATTERN BUT BEGIN TO DIVERGE BY
WED. THE GFS AND ECMWF PUSH THE TROUGH AXIS ACROSS THE REGION WED
WHILE GEFS AND CANADIAN MODELS SUGGEST A SLOWER PROGRESSION MOVING
THE TROUGH AXIS ACROSS THE REGION THU. DECIDED TO TREND TOWARDS
SLOWER GEFS IN KEEPING LIKELY POPS THROUGH THU BEFORE TAPERING OFF
TO SCT SHOWERS FRI. LATEST MODEL RUNS DO NOT SHOW THE TROPICAL
MOISTURE FEEDING INTO REGION AHEAD OF THE SYSTEM. THIS LEADS TO
LOWER MODEL QPF TOTALS FOR NEXT WEEK...1-3 INCHES INSTEAD OF 3-5 AS
SHOWN IN PREVIOUS RUNS. BC
&&

.AVIATION...SATELLITE AND RADAR IMAGERY SHOWED CLOUDS AND A FEW
SHOWERS MOVING ACROSS THE AREA THIS AFTERNOON. TREND HAS BEEN
FOR SHOWER ACTIVITY TO DECREASE IN COVERAGE AND INTENSITY. THIS
TREND SHOULD CONTINUE THROUGH EVENING...WITH ONLY AN ISOLATED LIGHT
SHOWER OR TWO OVER THE COASTAL WATERS AND NEAR THE OREGON BORDER BY
DAYBREAK SAT. CEILINGS HAVE BEEN MOSTLY VFR AT REPORTING METAR
SITES...BRIEFLY FALLING TO MVFR IN SHOWERS. THUS EXPECTING
VFR CONDITIONS TO PREVAIL TONIGHT AS THE SHOWER ACTIVITY DECREASES.
LIGHT WINDS AND PARTIAL CLEARING WILL ALLOW FOR PATCHES OF IFR CONDS
IN FOG AND LOW CLOUD LATE TONIGHT/EARLY SAT MORNING IN VALLEYS. DJB
&&

.MARINE...SEAS WILL CONTINUE TO SUBSIDE TONIGHT THROUGH SATURDAY
...THEN INCREASE TO ADVISORY LEVEL AGAIN SAT NIGHT AND SUNDAY IN
RESPONSE TO STRONG SOUTH WINDS. WIND WAVES WILL BE THE LARGEST
COMPONENT OF THE SEA STATE SAT NIGHT AND SUN...BEFORE ANOTHER WNW
SWELL HITS SUN NIGHT INTO MONDAY. ENP HAS BEEN OVERDONE ON SWELL
HEIGHTS COMPARED TO BUOY OBSERVATIONS ACROSS THE INNER WATERS. THUS
WILL UNDERCUT SWELL HEIGHTS BY 5-7 FT. BIGGER WAVE EVENT MAY BE IN
STORE AROUND MID WEEK...WITH SWELL UP TO 25 KT POSSIBLE. WAVE
GENERATION REGION LOOKS IFFY RIGHT NOW AND WAVE PERIODS SEEM TOO
SHORT...AROUND 13 SECONDS. PLUS...SMALL CHANGES IN THE GFS WIND
FIELD WILL MAKE FOR HUGE ERRORS IN SWELL HEIGHTS. UNDERCUT ENP WAVE
HEIGHTS ON WED BY 5 TO 7 FT AS WELL. GALE FORCE WINDS ARE EXPECTED
TO DEVELOP ACROSS THE NORTHERN WATERS SAT NGT AND SUN. 12Z/18Z NAM12
SHOWED A STRONG RIBBON OF SOUTHERLY WINDS DEVELOPING IN THE
WARM/STABLE SECTOR SAT NIGHT/SUN AS A MODERATELY STRONG COLD FRONT
APPROACHES. DID EXTEND THE GALE WATCH TO THE INNER NORTHERN WATERS
FROM CAPE MENDOCINO TO PT ST GEORGE. THOUGH THERE WILL BE STRONG
GALE FORCE WINDS AROUND CAPE MENDOCINO...LEFT HIGH END SMALL CRAFT
ADVISORY LEVEL WINDS FOR THE SOUTHERN WATERS. DJB
