AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
1001 PM PDT MON MAR 12 2012

.UPDATE...STRONG STORM SYSTEM IMPACTING THE PAC NW THIS EVENING
WITH SNOW FALLING TO THE COAST IN NRN AND CENTRAL OREGON. STRONG
CAA WITH THIS SYSTEM WILL RESULT IN RAPIDLY FALLING SNOW LEVELS
BEHIND THE FRONT. 00Z GUIDANCE SHOWS MORE CAA THAN PREVIOUS
RUNS...SO LOWERED SNOW LEVELS A LITTLE MORE THAN PREVIOUS FCST.
HOWEVER...GREATEST SNOW ACCUMULATIONS WILL REMAIN ABOVE 3500-4500
FT SO LEFT CURRENT HEADLINES AS IS. ALSO...STRONG SLY WINDS CONTINUE
AHEAD OF THE FRONT SO EXTENDED THE WIND ADVISORY ALONG THE REDWOOD
COAST FOR A FEW HOURS.
&&

.SYNOPSIS...A STRONG FRONT WILL MOVE INTO NW CALIFORNIA TONIGHT.
THIS COLD FRONT WILL BRING STRONG GUSTY WINDS AND HEAVY RAIN TO
THE REGION THROUGH TONIGHT. RAIN WILL TURN TO SNOW IN THE MOUNTAINS
TONIGHT AND DEPOSIT OVER A FOOT OF SNOW IN THE HIGHER ELEVATIONS
OF DEL NORTE AND TRINITY COUNTIES. ANOTHER STORM SYSTEM WILL
ARRIVE WEDNESDAY NIGHT WITH UNSETTLED WEATHER CONTINUING INTO THE
WEEKEND.
&&

.PREV DISCUSSION...ISSUED 322 PM PDT MON MAR 12 2012...A STRONG
STORM SYSTEM CONTINUES TO APPROACH THE AREA WITH A STRONG COLD
FRONT JUST OFF THE OREGON COAST. A STRONG COASTAL JET HAS
DEVELOPED OUT AHEAD OF THIS FRONT PRIMARILY FROM THE CAPE NORTH
INTO COASTAL OREGON LEADING TO INCREASING WINDS. GUSTS ARE NOW
APPROACHING 50 KT ALONG THE COAST WITH GUSTS OVER 40 MPH AT CEC
AND AT THE WEATHER SERVICE OFFICE AND OVER 50 MPH ON THE COASTAL
RIDGES. WINDS WILL GUST AS HIGH AS 60 MPH ON COASTAL HEADLANDS AND
ON THE COASTAL RIDGES THIS EVENING AND TONIGHT BEFORE THE COLD
FRONT MOVES SOUTH. GUSTS UP TO 45 MPH WILL ALSO BE POSSIBLE ACROSS
INTERIOR DEL NORTE AND HUMBOLDT COUNTY AND THEN FURTHER SOUTH INTO
MENDOCINO COUNTY TONIGHT INTO TUESDAY MORNING AS THE FRONT MOVES
SOUTH. IN ADDITION TO THE WINDS MOISTURE WILL BE ABUNDANT WITH
THIS SYSTEM WITH A LONG STREAM OF MOISTURE SPREADING WEST INTO THE
PACIFIC. AS THIS MOISTURE MEETS THE COASTAL RANGES CONSIDERABLE
MOISTURE CONVERGENCE WILL RESULT IN TOTAL LIQUID EQUIVALENT
PRECIPITATION OF 2 TO 4 INCHES ACROSS THE NORTHERN HALF OF THE CWA
AND 1 TO 3 INCHES IN THE SOUTH. THE HEAVIEST PRECIPITATION WILL
OCCUR IN THE SISKIYOU AND KING RANGES. THIS HEAVY RAINFALL WILL
RESULT IN RAPIDLY RISING RIVERS THROUGH WEDNESDAY. CURRENT CNRFC
FORECASTS DO NOT BRING ANY RIVERS INTO ACTION STAGE THROUGH
WEDNESDAY.

AS OF 2 PM TODAY SNOW LEVELS CONTINUE TO RANGE FROM 2500 TO 3500
FEET ACROSS THE CWA BUT SHOULD CONTINUE TO RISE AS WARM AIR ALOFT
ADVANCES INTO THE CWA TODAY. THIS WILL RESULT IN SNOW LEVELS
BETWEEN 3500 AND 4500 FEET TONIGHT...HIGHEST WEST...AS THE
HEAVIEST PRECIPITATION MOVES THROUGH THE AREA. THUS THE WINTER
STORM WARNINGS HAVE BEEN UPDATED TO INCLUDE THESE HIGHER SNOW
LEVELS. BY LATE TONIGHT AS THE COLD FRONT DIVES SOUTH SNOW LEVELS
WILL FALL...HOWEVER WITH PRECIPITATION RAPIDLY COMING TO AN END
WITH THE FRONTAL PASSAGE. SNOWFALL INTO LOWER ELEVATIONS AS LOW AS
2000 FEET SHOULD BE LIMITED TO 2 TO 6 INCHES. 1 TO 3 FEET MAY FALL
ABOVE 4500 FEET.

THE COLD FRONT WITH THIS SYSTEM WILL SLOWLY SINK SOUTH ON TUESDAY
WITH DRYING CONDITIONS DEVELOPING ACROSS THE NORTHWESTERN HALF OF
THE CWA. RAIN SHOWERS MAY LINGER ACROSS TRINITY AND MENDOCINO COUNTY
AS THE FRONT STALLS JUST SOUTH OF THE CWA. A WARM AIR ADVECTION
PATTERN WILL DEVELOP AS A NEW SYSTEM APPROACHES THE WEST COAST AND A
WARM FRONT MOVES NORTH. A FEW SHOWERS MAY DEVELOP OVER THE AREA
TUESDAY NIGHT INTO WEDNESDAY WITH THE WARM FRONT. A WEAK COLD FRONT
WILL STALL JUST NORTH OF THE AREA ON WEDNESDAY INTO WEDNESDAY NIGHT
ONLY TO BE REINFORCED BY A MORE POTENT SYSTEM WEDNESDAY NIGHT INTO
THURSDAY WHICH WILL SLAM INTO THE COAST WITH ANOTHER ROUND OF HEAVY
RAINFALL. SNOW LEVELS WITH THIS SYSTEM WILL BE EVEN HIGHER...LIKELY
ABOVE 5000 FEET...WHICH SHOULD LIMIT ANY NEED FOR WINTER WEATHER
PRODUCTS. HOWEVER THIS SECOND BOUT OF PRECIP MAY RESULT IN ISSUES
FOR AREA RIVERS AS 2-6 INCHES OF RAIN FALLS ACROSS THE CWA.

MUCH COLDER...UNSTABLE AIR WILL FILTER IN BEHIND THE FRONT WITH
REINFORCING SHORTWAVES MOVING THROUGH NORTHERN CALIFORNIA THROUGH
THE WEEKEND. THE INSTABILITY AND VERY COLD AIR ALOFT WILL ALLOW FOR
A CHANCE OF THUNDER AND MORE LIKELY SMALL HAIL SHOWERS AS THE DEEP
TROUGH SETTLES OVER THE WESTERN US. BY EARLY NEXT WEEK THE TROUGH
WILL BEGIN TO MOVE EAST WITH DRIER WEATHER POSSIBLE. RPA

.AVIATION...VFR CONDS WILL GIVE WAY TO MVFR AS MODERATE TO HEAVY
RAIN DEVELOPS ALONG THE COAST THIS EVENING...SPREADING INLAND
OVERNIGHT. GUSTY WINDS IN EXCESS OF 40 KTS (ESPECIALLY AT KCEC) WILL
QUICKLY DIMINISH LATE THIS EVENING ALONG THE NORTH COAST AS A FRONT
SWINGS THROUGH. DESPITE VERY STRONG WINDS (GREATER THAN 60 KTS)
ALOFT...WIND SHEAR IS NOT INCLUDED IN ANY TAF SITES AS MUCH OF THE
MOMENTUM WILL BE ABLE TO MIX TO THE SFC. JCA
&&

.MARINE...VERY POWERFUL FRONT WILL MOVE THROUGH LATER THIS EVENING.
STORM FORCE GUSTS ARE STILL ANTICIPATED RIGHT ALONG THE FRONT...WITH
HIGH END GALES FOR ALL WATERS. THE FRONT WILL SAG SOUTH OVERNIGHT
KEEPING WINDS UP MOST OF THE NIGHT SOUTH OF THE CAPE. WINDS AND SEAS
WILL DIMINISH RAPIDLY BEHIND THE FRONT...BUT SEAS WILL REMAIN
ELEVATED AS A POST FRONTAL SWELL MOVES IN.

ANOTHER FRONT APPROACHES THE WATERS WED NIGHT...WITH THE POTENTIAL
FOR ANOTHER ROUND OF GALE CONDS. MODELS ARE INDICATING A LARGE SWELL
MOVING INTO THE WATERS LATE IN THE WEEK...PEAKING 16-18 FT AT 13-14
SECONDS. JCA
