AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA...UDPATED
237 PM PST WED MAR 10 2010

.SYNOPSIS...A FEW SHOWERS WILL MOVE THROUGH THE REDWOOD COAST THIS
EVENING. OTHERWISE PARTLY CLOUDY AND DRY CONDITIONS ARE EXPECTED
THROUGH THURSDAY MORNING. A FEW SHOWERS ARE POSSIBLE LATE THURSDAY
AFTERNOON AHEAD OF THE NEXT FRONT. THE MAJORITY OF PRECIPITATION
WILL OCCUR ON FRIDAY WITH SNOW IN THE MOUNTAINS ABOVE 4000 FEET.
HIGH PRESSURE WILL BUILD INTO THE REGION SATURDAY WITH WARMER AND
DRIER WEATHER EXPECTED THROUGH EARLY NEXT WEEK.
&&

&&
UPDATED DISCUSSION...ADDED ISOLATED SHOWERS TO THE FORECAST FOR THIS
EVENING AS A BAND OF SHOWERS APPROACHES THE COAST FROM OFFSHORE.
THIS IS THE SRN EXTENT OF A WEAKENING WARM FRONTAL BOUNDARY
ASSOCIATED WITH A LOW MOVING INTO THE SE AK. AT THIS TIME SHOWERS
ARE EXPECTED TO REMAIN N OF CAPE MENDOCINO. BFG

.DISCUSSION...HIGH PRESSURE HAS PRODUCED DIMINISHING CLOUD COVER
THIS AFTERNOON WITH A FEW CUMULUS CLOUDS LINGERING OVER THE
MOUNTAINS NORTH OF THE MENDOCINO ZONES AND DRY CONDITIONS ARE
EXPECTED TO PERSIST THROUGH AROUND MIDDAY THURSDAY. FOR
TONIGHT...SOME CLOUD COVER PERSISTING ACROSS DEL NORTE COUNTY WHICH
SHOULD PREVENT THE MOST EFFICIENT RADIATIONAL COOLING FROM
OCCURRING. HOWEVER THE COASTAL ZONES SOUTH OF AROUND KLAMATH ARE
EXPECTED TO EXPERIENCE COOLING INTO THE MID 30S...A COUPLE OF
DEGREES WARMER THAN THE PRECEDING NIGHT. WILL GO AHEAD AND ISSUE
FROST ADVISORY BECAUSE ALTHOUGH THE AIRMASS HAS WARMED
SOMEWHAT...THE RADIATIONAL COOLING SHOULD BE FAIRLY EFFICIENT.

MODELS HAVE BEEN SPEEDING UP THE APPROACH OF THE NEXT FRONTAL SYSTEM
TO AFFECT THE REGION. THE LATEST RUNS OF NAM...GFS AND ECMWF AGREE
ON BRINGING LIGHT PRECIP INTO THE NORTHWEST PORTION OF THE CWA
THURSDAY AFTERNOON...INCREASING SOMEWHAT THURSDAY NIGHT. THE
HEAVIEST PRECIPITATION IS STILL LINED UP FOR THE FRIDAY 12Z-00Z TIME
PERIOD. RFC IS ADVERTISING AROUND 0.25 INCHES FOR MOST
AREAS...INCREASING TO 0.50 NEAR CAPE MENDOCINO AND UP TO 0.75 OVER
SMITH BASIN THROUGH 12Z FRIDAY...WITH AN ADDITIONAL 1-2 INCHES BY
00Z SATURDAY. THE SMITH BASIN WILL MOST LIKELY EXCEED 3 INCH TOTALS
FOR THE EVENT. SNOW LEVEL IS EXPECTED TO DROP FROM 5000 FT EARLY
FRIDAY MORNING TO 4000 FT BY THE AFTERNOON...AND STILL LOWER IN SOME
OF THE SHELTERED INLAND VALLEYS. SNOW LINE WILL FALL BELOW 3000 FT
FRIDAY NIGHT BUT QPF WILL BE ON A FAST DECLINE THROUGH THAT TIME
PERIOD...SO DO NOT EXPECT ANY SIGNIFICANT LOWER ELEVATION SNOWFALL.

THE MOUNTAINS ABOVE AROUND 4000 FT WILL LIKELY PICK UP 8 TO 10
INCHES OF SNOW BY THE TIME THE EVENT WRAPS UP FRIDAY EVENING. THIS
MAY END UP A BORDERLINE ADVISORY/WARNING EVENT FOR THE HIGHER
ELEVATIONS BUT WILL BE TOUGH TO VERIFY DUE TO LACK OF VALIDATION
POINTS. WILL HOLD OFF ON ISSUING A WATCH AT THIS JUNCTURE.

AN UPPER RIDGE WILL BUILD INTO THE EASTERN PACIFIC ON SATURDAY...AND
BEGIN TO SHIFT EAST ON SUNDAY AS ANOTHER LONG WAVE TROUGH APPROACHES
EARLY NEXT WEEK. MODELS CONTINUE TO SHOW POOR CONTINUITY IN THE
TIMING AND INTENSITY OF THIS TROUGH...HOWEVER A SOLUTIONS INDICATE
THAT PRECIPITATION WILL BE DELAYED UNTIL TUESDAY. BEYOND TUESDAY
HEDGED TOWARD THE LOWER END OF CLIMO FOR MID WEEK. CC

.AVIATION...VFR CONDITIONS TO PREVAIL THROUGH TONIGHT. A FEW SITES
ACROSS THE INTERIOR MAY SEE LOW IFR CONDITIONS DUE TO FOG. DJB

27 SPIKED TO 18 FT FOR 4-5 HOURS. THE ENP AND WAVEWATCH INDICATE
SWELL TO SLOWLY SUBSIDE TONIGHT THROUGH THU MORNING..THEN ANOTHER
SWELL TO SPREAD INTO THE REGION THU NIGHT. A WARM FRONTAL BOUNDARY
WILL APPROACH ON THURSDAY...PERHAPS RESULTING IN A FEW GUSTS TO 35
KT. THE MORE SERIOUS WINDS SHOULD HOLD OFF UNTIL LATE THU NIGHT INTO
EARLY FRIDAY...WHEN A COLD FRONT AND PERHAPS CONVECTION...MAY
GENERATE GUSTS TO 40 KTS. GFS AND NAM12 CERTAINLY INDICATE THE
POTENTIAL FOR DOWNWARD TRANSPORT...WITH BOUNDARY LAYER SPEEDS UP TO
45 KTS. THUS...HOISTED A GALE WARNING FOR THE NORTHERN OUTER WATERS.
WITH STEEP WIND WAVES EXPECTED NEAR 10 FT BY EARLY FRIDAY
MORNING...HOISTED A WATCH FOR HAZARDOUS SEAS AS WELL. HARD TO TELL
IF THE GALE WILL NEED TO BE EXTENDED TO THE INNER WATERS...BUT DID
INCLUDE MENTION OF LOCALIZED GUSTS TO 35 KT...JUST IN CASE. ENP AND
SWAN INDICATE A LARGER SWELL TO HIT FRI NIGHT INTO SAT...BUT WITH
SHORT PERIODS NEAR 13-14 SECONDS. HOISTED A HAZARDOUS SEAS WATCH FOR
