AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
502 PM PST MON DEC 22 2008

.SYNOPSIS...RAIN AND HIGHER ELEVATION SNOW SHOWERS WILL CONTINUE
THROUGH THIS EVENING AS AN AREA OF LOW PRESSURE CENTERED OVER
WASHINGTON MOVES OFF TO THE EAST. ANOTHER STORM WILL APPROACH THE
REGION TOMORROW NIGHT AND WILL LIKELY AFFECT HOLIDAY TRAVEL WITH
RAIN...SNOW AND BLUSTERY WINDS. YET ANOTHER LOW PRESSURE SYSTEM WILL
APPROACH THE REGION CHRISTMAS DAY.

&&

.SHORT TERM...TODAY THROUGH THURSDAY...THE LOW PRESSURE SYSTEM OVER
WASHINGTON WILL CONTINUE TO DRIVE RAIN AND SNOW SHOWERS ACROSS THE
AREA TONIGHT AS IT SLOWLY MOVES OFF TO THE EAST. VERY ISOLATED
THUNDERSTORMS WILL BE POSSIBLE TONIGHT OVER THE WATERS NORTH OF CAPE
MENDOCINO AND ALONG THE REDWOOD COAST AS THE COLD AIR KEEPS UNSTABLE
CONDITIONS IN PLACE. THUNDERSTORM CHANCES WILL DIMINISH IN THE
MORNING AS A STRONG CAP AT 700MB ASSOCIATED WITH A WEAK SHORTWAVE
RIDGE DEVELOPS.

THE NEXT LOW PRESSURE SYSTEM...CURRENTLY LOCATED AT 50N/150W...IS
PROGGED TO MOVE SOUTHEAST AND MOVE ONSHORE SOUTH OF THE BAY AREA
WEDNESDAY EVENING. WITH THIS TRACK...SOUTHERN MENDOCINO COUNTY WILL
BEGIN TO COME UNDER THE INFLUENCE OF A WARM FRONTAL BOUNDARY
TOMORROW EVENING. SNOW LEVELS WILL BE ON THE RISE WITH THE WARM AIR
ADVECTION THAT WILL BE IN PLACE SO SNOW ACCUMULATIONS WILL BE
LIMITED TO THE HIGHER ELEVATIONS IN EASTERN MENDOCINO AND TRINITY
COUNTY. LIGHT RAIN IS EXPECTED ELSEWHERE ACROSS MENDOCINO
COUNTY...SPREADING NORTH INTO HUMBOLDT AND TO A LESSER EXTENT DEL
NORTE COUNTY BY WED MORNING. SOUTHWEST WINDS WILL BE QUITE STRONG
WITH THIS SYSTEM...ESPECIALLY IN MENDOCINO COUNTY WHERE GUSTS TO
NEAR 30 MPH WILL BE POSSIBLE NEAR POINT ARENA.

THIS SYSTEM WILL QUICKLY MOVE OFF TO THE EAST WITH ANOTHER COLDER
SYSTEM MOVING INTO NW CALIFORNIA EARLY CHRISTMAS MORNING. SNOW
LEVELS WILL QUICKLY DROP BELOW 2000 FT IN DEL NORTE...EASTERN
HUMBOLDT AND NORTHERN TRINITY COUNTIES ON CHRISTMAS MORNING WITH
SNOW ACCUMULATIONS IN THESE AREAS CLOSING IN ON 5 INCHES WITH LOCAL
AREAS RECEIVING UP TO 8 INCHES BY 6 AM. SNOW LEVELS WILL BE ABOVE
2500 FT IN SOUTHERN TRINITY AND MENDOCINO COUNTIES AT THIS TIME WITH
SNOW ACCUMULATIONS OF 1 TO 3 INCHES EXPECTED. WINDS WILL BECOME
GUSTY ONCE AGAIN...THIS TIME OUT OF THE NORTHWEST...WITH GUSTS NEAR
25 MPH POSSIBLE ALONG THE REDWOOD COAST AND IN HIGHER ELEVATIONS
THROUGHOUT THE DAY. WIDESPREAD RAIN SHOWERS...AND SNOW SHOWERS ABOVE
2000 FT...CAN BE EXPECTED THROUGHOUT THE REMAINDER OF THE DAY ON
CHRISTMAS. KOENEKE

.LONG TERM...THURSDAY NIGHT THROUGH MONDAY...COLDER AIR WILL REMAIN
OVER THE REGION THURSDAY NIGHT WITH SNOW LEVELS EXPECTED TO LOWER
DOWN TO AROUND 1000 TO 1500 FEET BY FRIDAY MORNING. THE SNOW LEVELS
WILL RISE ABOVE THE MOUNTAIN PASSES BY FRIDAY EVENING AS THE
SYNOPTIC MODELS ARE IN GOOD AGREEMENT ON A WEAK UPPER LEVEL RIDGE
MOVING OVER THE PACIFIC NW ON FRIDAY. THE MODELS SHOW A KINK IN THE
UPPER RIDGED FRIDAY NIGHT AND FORECAST A SURFACE WARM FRONT TO PUSH
ACROSS NW CALIFORNIA. MODELED PRECIPITABLE WATER INCREASES TO NEAR
AN INCH OVER THE NE PACIFIC FRIDAY NIGHT AND ISENTROPIC ANALYSIS
SHOWS GOOD LIFT WITH THE FRONT. ANOTHER WARM FRONT IS EXPECTED FOR
SUNDAY NIGHT WITH SIMILAR PRECIPITABLE WATER AND LIFT AS THE FRIDAY
STORM. ALTHOUGH THERE IS ALWAYS UNCERTAINTY OF HOW MUCH RAIN TO
EXPECT FOR FORECASTS BEYOND 4 DAYS...CURRENT MODEL RUNS SHOW THESE
TWO SYSTEMS HAVE THE ESSENTIAL INGREDIENTS TO PRODUCE DECENT
RAINFALL AMOUNTS. THE SNOW LEVELS SHOULD REMAIN ABOVE 4000 FEET AND
DO NOT EXPECT ANY SNOW ISSUES FRIDAY NIGHT THROUGH MONDAY. TH

&&

.AVIATION...SHOWERS AND A COOLER/LESS STABLE AIR MASS WILL CONTINUE
TO SPREAD INTO THE REGION THIS EVENING. EXPECTING MOSTLY VFR WITH
OCCASIONAL MVFR CIGS/VSBYS IN SHOWERS. LIGHT OFFSHORE FLOW DEVELOPS
TONIGHT WHICH SHOULD RESULT IN DECREASING SHOWER COVERAGE/INTENSITY
AND SOME DRYING BY EARLY TUE. WITH PARTIAL CLEARING...IFR IN FOG AND
LOW CLOUDS EXPECTED EARLY TUE MORNING IN THE VALLEYS. DJB

&&

.MARINE...COLD AIR SURGE WAS SLIDING DOWN THE NORCAL COAST THIS
AFTERNOON. NW SWELL SHOULD BE ON A DOWNWARD TREND NORTH OF CAPE
MENDOCINO THIS EVENING...BUT MAY STILL SPIKE NEAR 19 FT EARLY THIS
EVENING SOUTH OF CAPE MENDOCINO. THE NW SWELL WILL CONTINUE TO TREND
DOWNWARD TUESDAY THROUGH WEDNESDAY...BOTTOMING OUT NEAR 6 FT ON WED.
NEXT ISSUE OF CONCERN IS THE GALE FORCE WINDS SOUTH OF THE CAPE TUE
NIGHT INTO WED MORNING. A LOW  PRESSURE SYSTEM SHOULD MOVE INSIDE
130W NORTH OF 40N TUE NIGHT AND WED MORNING. CURRENT INDICATIONS ARE
FOR THE LOW TO HEAD TOWARDS CENTRAL CALIFORNIA. FOR NOW...TOOK THE
MEAN FROM THE GFS...ECMWF AND NAM12 AND AVERAGED THE WINDS FROM THE
NAM12 AND GFS. IF THE LOW TAKES A TRACK FURTHER SOUTH...THERE WILL
BE LESS POTENTIAL FOR STRONG WINDS. A TRACK FURTHER TO THE
NORTH...MORE POTENTIAL...WITH GALE FORCE WINDS PERHAPS CREEPING INTO
THE SOUTHERN PERIPHERY OF THE NORTHERN COASTAL WATERS. THE LOW
SHOULD HEAD SOUTHWARD DURING THE DAY ON WED...AT LEAST THAT IS THE
CONSENSUS AT THIS POINT. NEXT COLD SURGE WILL ARRIVE ON THU. LATEST
ENP CONTINUES TO INDICATE SEAS INCREASING ON THU...UP TO 30 FT WITH
PERIOD OF 15 SECONDS. STILL SOMEWHAT SKEPTICAL DUE TO THE
UNCERTAINTIES IN THE GFS WIND FIELDS WED AND THU. EVEN WITH THE
MODELS FLIP FLOPPING AROUND FROM ONE RUN TO THE NEXT...THE ENP SEA
STATE FORECAST FOR THURSDAY HAS REMAINED CONSISTENT. THUS...WILL
CONTINUE TO UNDERCUT THE SWELL HEIGHTS...DUE TO THE TENDENCY OF THE
MODEL TO OVERSHOOT THE HEIGHTS. DJB

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
HIGH SURF ADVISORY UNTIL 6 TO 8 PM PST TONIGHT.
HAZARDOUS SEAS WARNING ALL WATERS THROUGH THIS EVENING.
