AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE EUREKA CA
159 PM PST MON FEB 22 2010

.SYNOPSIS...HIGH PRESSURE WILL BUILD BRIEFLY OVER THE REGION
TODAY. A FRONT WILL BRING RAIN TO THE AREA ON TUESDAY...WITH THE
THREAT OF SHOWERS CONTINUING THROUGH THE END OF THE WEEK.

&&

.DISCUSSION...HIGH PRESSURE OVER THE REGION TODAY WILL MAINTAIN THE
NICE LATE WINTER WEATHER BEFORE CLOUDS ASSOCIATED WITH THE NEXT
FRONTAL SYSTEM INVADE THE SKIES FROM WEST TO EAST.  CLOUD COVER
WILL CONTINUE TO INCREASE THROUGH THE AFTERNOON HOWEVER INITIAL RAINFALL
AT THE COAST WILL HOLD OFF UNTIL AFTER MIDNIGHT...AND SHOULD NOT
FALL IN EARNEST UNTIL CLOSER TO SUNRISE. AS THE FRONT MOVES ACROSS
THE CWA TOMORROW RAIN WILL SPREAD INLAND LATER IN THE MORNING HOWEVER
FREE AIR SNOW LEVELS SHOULD REMAIN WELL ABOVE PASS LEVEL.  ONCE AGAIN
THE TRICKY FORECAST WILL BE HOW MUCH COLD AIR RESIDES ACROSS THE
INTERIOR VALLEYS TONIGHT AND THE RESULTING THREAT OF LOW TRAPPED
SNOW DURING THE MORNING HOURS.  BASED ON THIS MORNINGS LOW TEMPERATURES
TONIGHT AND EARLY TOMORROW MAY BE CLOSE TO FREEZING AGAIN
HEIGHTENING THE CHANCE OF SNOW LOWER THAN 5000 FEET.  HOWEVER AT
THIS TIME SAT PICTURES SUGGEST THE ADVECTION OF HIGHER CLOUDS
THROUGHOUT THE DAY AND MODELS ALSO DEPICT DECENT CLOUD COVER TONIGHT
OVER THE INTERIOR SO THOUGHTS ARE THE RADIATIVE COOLING PROCESSES WILL
BE LIMITED.  WILL KEEP THE HIGHER SNOW LEVELS AND NOT ISSUE ANY NON
ROUTINE PRODUCTS TO ADDRESS SNOW.  AS FAR AS RAIN AMOUNTS WITH THIS
SYSTEM  MODELS INDICATE ABUNDANT MOISTURE WITH THE FRONT. THIS
COMBINED WITH NEARLY ONSHORE FLOW WILL LEAD TO GOOD OROGRAPHIC LIFT.
SO HIGH RAINFALL AMOUNTS ARE EXPECTED. TOTAL QPF WILL BE NEAR 0.5
INCH ACROSS DEL NORTE COUNTY, 0.5-1.0 INCH ACROSS HUMBOLDT COUNTY,
NEAR 1 INCH ACROSS TRINITY COUNTY, AND JUST OVER 1 INCH ACROSS
MENDOCINO COUNTY. THE MORE RAIN FAVORED SPOTS WILL RECEIVE 2-3
INCHES. THE TUESDAY SYSTEM WILL PASS THROUGH BY TUESDAY NIGHT AND BE
FOLLOWED BY ANOTHER BRIEF BREAK WED AND EARLY THURSDAY.  MORE RAIN
LATE THURSDAY AND FRIDAY AS A SIMILAR FRONTAL SYSTEM APPROACHES FROM
THE WEST.

&&

.AVIATION...VFR CONDITIONS EXPECTED TO PREVAIL...HOWEVER CEILINGS
WILL LOWER TO NEAR MVFR BY MID MORNING TUESDAY AS A STORM SYSTEM
APPROACHES FROM THE WEST. SOUTHERLY WINDS WILL INCREASE AND BECOME
GUSTY AS WELL TUESDAY...WITH SOME MODERATE LLWS POSSIBLE. TIMING ON
RAIN IS INCONSISTENT IN THE MODEL RUNS...BUT HAVE FORECAST EARLY TO
MID MORNING FOR RAIN ONSET ATTM. CONDITIONS WILL LIKELY DETERIORATE
AFTER 18Z TUESDAY AS THE RAIN INTENSITY INCREASES. HENRY

&&

.MARINE...SOUTHERLY WINDS WILL INCREASE TONIGHT AND TUESDAY AS A
WARM FRONT LIFTS NORTH AHEAD OF AN APPROACHING STORM SYSTEM. WINDS
WILL BECOME STRONG AND GUSTY TUESDAY HOWEVER....THERE HAVE BEEN SOME
INCONSISTENCIES IN THE MODELS ON THE STRENGTH OF THE WIND. HAVE
ISSUED A SMALL CRAFT ADVISORY FOR WIND AND WAVES FOR NOW...BUT A
GALE WARNING MAY STILL BE NEEDED. MODERATE SWELL TRAIN OF 10 TO 12
FT WILL BUILD FOR WEDNESDAY AND THURSDAY...ALONG WITH INCREASING
WINDS AHEAD OF THE NEXT APPROACHING SYSTEM FOR THURSDAY AND FRIDAY.
MODELS STILL CONSISTENT IN BRING A LARGE SWELL OF 19 FT FOR
SATURDAY. HENRY

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...
