AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
214 PM PST SAT DEC 25 2010

.SYNOPSIS...COLDER AIR WILL MOVE INTO THE AREA OVERNIGHT WITH
SHOWERS AND A FEW THUNDERSTORMS EXPECTED. ANOTHER STORM IS LIKELY TO
BRING SIGNIFICANT RAINS AND HIGH ELEVATION SNOWS TO THE REGION
MONDAY NIGHT INTO TUESDAY.

&&

.DISCUSSION...HAPPY HOLIDAYS FROM THE STAFF AT WEATHER FORECAST
OFFICE EUREKA! THE MAIN FORECAST CONCERNS INCLUDE SNOW AMOUNTS AND WIND
TONIGHT...THEN THE NEXT SYSTEM LATE MONDAY INTO TUESDAY.

THE COLD FRONTAL BOUNDARY IS MOVING THROUGH THE AREA AT THE CURRENT
TIME WITH SYNOPTIC AND WET BULB EFFECTS BEGINNING TO DRIVE DOWN
SNOW LEVELS. STEADY PRECIPITATION WILL BE WANING DURING THE
REMAINDER OF THE AFTERNOON BUT SATELLITE IMAGERY CONFIRMS PLENTY
OF OPEN CELL CUMULUS FOLLOWING THE FRONT...WHICH WILL PUSH ONSHORE
TONIGHT PRODUCING SHOWERS AND POSSIBLY A FEW THUNDERSTORMS.
HEAVIER SHOWERS ARE LIKELY TO CONTAIN SMALL HAIL WHICH MAY COMPLICATE
ROAD TRAVEL BELOW THE SNOW LEVEL. SPEAKING OF SNOW LEVEL...THE
AIRMASS SHOULD SUPPORT A RAIN CHANGEOVER TO SNOW BETWEEN 2500 TO
3000 FEET LATER TONIGHT WITH A COUPLE OF INCHES OF SNOW
ACCUMULATION AT THAT LEVEL...AND SEVERAL MORE INCHES ABOVE 3000
FEET. WITH FAVORABLE JET DYNAMICS AND CURRENT SATELLITE
INFORMATION...NOT TO MENTION A HEAVY TRAVEL DAY IN STORE FOR
TOMORROW...FEEL THAT A WINTER WEATHER ADVISORY IS WARRANTED FOR
TONIGHT INTO EARLY SUNDAY. SOUTH WINDS WILL INCREASE ONCE AGAIN
OVERNIGHT AFTER A TEMPORARY LULL...WITH GUSTS TO 35 OR 40 MPH
ALONG THE COAST NORTH OF TRINIDAD TOWARDS SUNRISE.

PRECIPITATION WILL DIMINISH DURING THE AFTERNOON SUNDAY...BUT THE
COLD AIRMASS WILL STILL SUPPORT A FEW SHOWERS. THE THUNDERSTORM
THREAT SHOULD END BY AFTERNOON AS THE AIRMASS SLOWLY STABILIZES.
THE NEXT SYSTEM SHOULD BRING LIGHT STRATIFORM PRECIP TO THE NORTH
COAST LATE SUNDAY NIGHT...WITH PRECIPITATION SLOWLY FILLING IN TO
THE EAST AND SOUTH BY MONDAY NIGHT. MOISTURE TAP LOOKS TO
CONSOLIDATE MONDAY NIGHT INTO TUESDAY...WITH A FAIRLY HIGH QPF
EVENT LOOKING INCREASINGLY LIKELY. POPS WERE BUMPED UP
SIGNIFICANTLY FOR THESE PERIODS. WHILE THIS APPEARS TO BE A WARMER
STORM...SNOW LEVELS MAY INITIALLY RESPOND SLOWLY DUE TO TRAPPED
COLDER AIR IN VALLEYS SUCH AS THOSE IN EASTERN TRINITY COUNTY. A
STRONG COLD FRONT WILL SWEEP THROUGH THE AREA WEDNESDAY
AFTERNOON...WITH SNOW LIKELY FALLING AT OR BELOW THE PASSES. THIS
IS A CERTAINTY BY WEDNESDAY NIGHT AS TEMPS ALOFT SUPPORT SNOW
LEVELS AS LOW AS 1000-1500 FEET. EVEN THOUGH PRECIPITATION SHOULD
DIMINISH BY THAT TIME...VERY LITTLE SNOW AT THESE ELEVATIONS CAN
MAKE FOR A TREACHEROUS...HIGH IMPACT EVENT. AT THIS POINT FRIDAY
LOOKS TO HAVE THE BEST CHANCE FOR DRY WEATHER...BUT THIS MAY
CHANGE AS THE PATTERN REMAINS UNSETTLED THROUGH MOST OF NEXT WEEK.
BURGER

&&

.AVIATION...AREAS OF MVFR/IFR CONDITIONS WILL CONTINUE AS MAIN PUSH
OF RAIN/HIGH ELEVATION SNOW MOVES THROUGH THE REGION THIS EVENING.
SHOWERS WILL CONTINUE OVERNIGHT ALTHOUGH MVFR/IFR CONDITIONS ARE
EXPECTED TO DECREASE IN COVERAGE. WINDS WILL ALSO DECREASE THIS
EVENING...BUT THEN INCREASE ONCE AGAIN SUNDAY MORNING AHEAD OF THE
NEXT APPROACHING FRONT. BETTWY

&&

.MARINE...WINDS AND SEAS WILL SUBSIDE TEMPORARILY THIS
EVENING...WHILE 7 TO 9 FT NW SWELL CONTINUES. ANOTHER COLD FRONT
WILL APPROACH THE REGION LATE TONIGHT...RESULTING IN INCREASING S
WINDS AND WIND WAVES. SMALL CRAFT ADVISORIES WILL REMAIN IN EFFECT
ACCORDINGLY. MODERATE WNW SWELL WILL CONTINUE THROUGH MONDAY AS
WELL. CONDITIONS WILL WORSEN FOR WEDNESDAY AND THURSDAY AS NORTHERLY
FLOW PATTERN BRINGS NW GALE FORCE GUSTS TO THE OUTER WATERS...AND
LARGE NW SWELL FORECAST TO PEAK AT 16 TO 17 FT WEDNESDAY. BETTWY
