AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
423 AM PST FRI FEB 26 2010

.SYNOPSIS...A COLD FRONT WILL PRODUCE PERIODS OF HEAVY RAIN AND HIGH
ELEVATION SNOW ACROSS NORTHWEST CALIFORNIA TODAY. THE RAIN WILL TURN
TO SHOWERS THIS EVENING...WITH ISOLATED THUNDERSTORMS ALONG THE
COAST THROUGH THE NIGHT. HIGH PRESSURE WILL PROVIDE DRY AND STABLE
WEATHER FOR THE WEEKEND.

&&

.DISCUSSION...SATELLITE IMAGERY SHOWS A LOW NEAR 42N 143W EARLY THIS
MORNING...WITH THE EUREKA CWA POSITIONED BETWEEN A WARM FRONT TO THE
EAST AND A COLD FRONT TO THE WEST. RADAR IMAGERY SHOWS LIGHT SHOWERS
ACROSS NW CA EARLY THIS MORNING WITH A BAND OF PRECIPITATION
ASSOCIATED WITH THE COLD FRONT ABOUT 65 MILES OFFSHORE THE HUMBOLDT
COUNTY COAST. GUSTY SOUTH WINDS WILL CONTINUE THIS MORNING AS THE
FRONT NEARS THE COAST. MODELS ARE IN GREAT AGREEMENT WITH THE
POSITION AND TIMING OF THE LOW AND FORECAST THE FRONT TO GENERATE
RAIN ACROSS THE REGION LATER THIS MORNING...AND PERSIST INTO THE
LATE AFTERNOON. SATELLITE TPW SHOWS A DECENT BAND OF MOISTURE WITH
PW GREATER THAN AN INCH ASSOCIATED WITH THE FRONT. SATELLITE DERIVED
WINDS AND WATER VAPOR IMAGERY SHOWS AN UPPER LEVEL 120+KT JET STREAK
ROUNDING THE BASE OF THE TROUGH. THIS JET STREAK WILL EXTEND TOWARDS
MENDOCINO COUNTY LATER THIS MORNING AND PROVIDE SUFFICIENT LIFT TO
GENERATE MODERATE TO HEAVY RAINFALL ACROSS THE REGION.

THE RAIN WILL BE MOST SIGNIFICANT ACROSS SOUTHERN HUMBOLDT AND
MENDOCINO COUNTIES WHERE 2 TO 4 INCHES ARE EXPECTED. QPF OF 1 TO 2
INCHES ARE EXPECTED ELSEWHERE. MAINSTEM RIVERS WILL RISE TODAY AND
TONIGHT IN RESPONSE TO THE RAIN...AND THE EEL RIVER AT FERNBRIDGE IS
EXPECTED TO RISE ABOVE MONITOR STAGE BY SAT MORNING. SNOW LEVELS ARE
CURRENTLY NEAR 5500 FEET AND WILL LOWER BEHIND THE COLD FRONT DOWN
TO 4000 FEET BY THIS EVENING. HAVE MAINTAINED WINTER STORM WARNING
FOR HIGH ELEVATION SNOW AS IS AND AGREE THAT THE MOST SIGNIFICANT
SNOW WILL OCCUR ABOVE 4500 FEET. HOWEVER...LOW DEW POINTS AND HEAVY
PRECIP MAY RESULT IN SNOW DOWN TO 2500 TO 3500 FEET ACROSS EASTERN
TRINITY COUNTY. MODELED INSTABILITY PARAMETERS SHOW A SLIGHT CHANCE
FOR CONVECTION AND THUNDERSTORMS TONIGHT AS THE TROUGH AXIS NEARS
THE COAST AND HAVE EXTENDED ISOLATED THUNDERSTORMS TO INCLUDE THE
COASTAL ZONES.

RAIN WILL LIGHTEN AND CEASE TONIGHT AS THE LOW MOVES SOUTH OF THE
REGION. A FEW SHOWERS WILL LINGER AROUND SAT MORNING. HIGH PRESSURE
WILL BUILD ACROSS THE REGION SATURDAY AND EXPECT CLEARING BY THE
AFTERNOON. HIGH PRESSURE WILL SUPPORT DRY AND STABLE WEATHER THROUGH
SUNDAY.

MODELS ARE IN FAIR AGREEMENT ON ANOTHER STORM IMPACTING THE REGION
MONDAY NIGHT...FOLLOWED BY A COLDER STORM ON TUE NIGHT. THERE IS
SOME DISAGREEMENT ON THE POSITION OF THE TUE LOW...BUT THIS STORM
HAS MORE POTENTIAL THAN RECENT STORMS TO PRODUCE MORE SIGNIFICANT
SNOW. MODELS DIVERGE ON SOLUTIONS BEYOND WED BUT ALL GENERALLY AGREE
ON HIGH PRESSURE ACROSS THE REGION WED NIGHT AND THU AND HAVE
REDUCED POPS FOR THIS TIME FRAME. EXPECT ANOTHER STORM FRI OR SAT
BUT CONFIDENCE ON TIMING AND LOCATION ARE VERY LOW AND LEANED
TOWARDS CLIMATOLOGY FOR THE FORECAST BEYOND THU. TH

&&

.AVIATION...A FRONTAL SYSTEM MOVING ACROSS THE REGION WILL BRING
CONTINUED GUSTY S WINDS TO THE FORECAST AREA THIS MORNING...ALONG
WITH A CHANCE OF LOW LEVEL WIND SHEAR DUE TO STRONGER WINDS ABOVE
THE SURFACE. RAIN WILL CONTINUE...HEAVY AT TIMES...ACROSS THE AREA
WITH VSBY GENERALLY IN THE MVFR CATEGORY ALTHOUGH PERIODIC DIPS TO
IFR MAY BE EXPECTED. CIGS WILL BE MAINLY MVFR. SNOW WILL AFFECT THE
ELEVATIONS ABOVE ABOUT 4000 FT TODAY AND 3500 FT TONIGHT. CMC

&&

.MARINE...STRONG SOUTH WINDS ARE EXPECTED TO CONTINUE THIS MORNING
UNTIL SHORTLY AFTER SUNRISE...WITH GALE FORCE GUSTS COMMON OVER THE
OUTER WATERS AND SPORADICALLY OCCURRING NEAR SHORE. BY MID MORNING
BOTH WINDS AND SEAS SHOULD BEGIN TO DECLINE. WINDS WILL REMAIN
GENERALLY LIGHT TO MODERATE THROUGH THE WEEKEND AS A SPLITTING STORM
SYSTEM MOVES ONSHORE...BUT A LONG PERIOD WEST SWELL WILL BEGIN TO
AFFECT THE WATERS ON SATURDAY. EXPECT WAVES OF AROUND 15 FT BY 15
SECONDS ON SATURDAY. ONLY A SMALL DECLINE IN WAVE HEIGHT IS EXPECTED
THROUGH EARLY NEXT WEEK...WITH A BIGGER LONG PERIOD WEST SWELL
FORECAST TO MOVE IN ON TUESDAY. AN APPROACHING LOW PRESSURE TROUGH
WILL BRING SOUTH WINDS UP TO SCA SPEEDS AGAIN ON MONDAY. CILIBERTI
