AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
300 AM PST FRI NOV 26 2010

.SYNOPSIS...A COLD FRONT WILL APPROACH THE REGION LATER
TODAY...WITH RAIN AND HIGHER ELEVATION SNOW OVERSPREADING THE AREA
OVERNIGHT. SHOWERS WILL CONTINUE INTO SATURDAY...WITH SNOW LIKELY
IMPACTING TRAVEL OVER THE PASSES.

&&

.DISCUSSION...THE MAIN FORECAST FOCUS CONTINUES TO BE SNOW LEVELS
AND AMOUNTS TONIGHT INTO SATURDAY NIGHT.

A COLD FRONT WAS LOCATED ABOUT 300 NM NW OF EUREKA EARLY THIS
MORNING...WITH INCREASING CLOUDS NOTED AHEAD OF THIS BOUNDARY. A
POWERFUL JET ALOFT MOVING IN FROM THE WEST WILL INTERACT WITH THIS
BOUNDARY LATER TODAY AND OVERNIGHT RESULTING IN SURFACE
CYCLOGENESIS AND STRENGTHENING SOUTHERLY FLOW. THE PRECIPITATION
THREAT FOR TODAY WILL HOLD OFF UNTIL AT LEAST LATE MORNING...WITH
MANY AREAS LIKELY TO STAY DRY DURING THE DAYLIGHT HOURS ESPECIALLY
TRINITY AND MENDOCINO COUNTIES. OVERNIGHT...A WAVE DEVELOPS ALONG
THE SURFACE FRONT AS IT BISECTS THE FORECAST AREA WHICH SHOULD
HELP ENHANCE RAIN AND HIGHER ELEVATION SNOW. RECENT RAOBS AND
MODELED SOUNDINGS SUGGEST DRY AIR ALOFT WILL TAKE SOME TIME TO
FULLY SATURATE...AND WHILE THIS INITIALLY WILL CAUSE LOWER
QPFS...EVAPORATIVE PROCESSES SHOULD SIGNIFICANTLY DRIVE DOWN THE SNOW
LEVEL LATER TONIGHT. ADDITIONALLY...TRAPPED COLDER AIR IN OUR
UPPER TRINITY VALLEYS WILL LIKELY HAVE A DIFFICULT TIME SCOURING
OUT AND GIVEN THE RECENT COLD SPELL...SNOW IS LIKELY TO STICK ONCE
THE CHANGEOVER OCCURS. SO THE WINTER STORM WATCH WAS UPGRADED TO A
WARNING FOR TRINITY COUNTY. ATMOSPHERIC PROFILES SUGGEST SOME
MARINE INFLUENCE SHOULD KEEP SNOW LEVELS RELATIVELY HIGH THROUGH
THE BULK OF THE EVENT ACROSS INTERIOR DEL NORTE...HUMBOLDT AND
MENDOCINO COUNTIES...WITH SNOW LEVELS PLUMMETING AROUND DAYBREAK
TOMORROW AS THE UPPER TROUGH SWINGS ACROSS. THEREFORE WE WENT WITH
A WINTER WEATHER ADVISORY FOR THESE ZONES.

SHOWERS SHOULD BE FAIRLY WIDESPREAD TOMORROW WITH THE COLD...NEARLY
SATURATED AIRMASS IN PLACE. ADDITIONALLY...FAVORABLE UPPER JET
SUPPORT AND NEGATIVE EPV VALUES SUGGEST A GOOD LIKELIHOOD OF
FURTHER SNOW ACCUMULATIONS AT LOWER ELEVATIONS. THERMAL
INSTABILITY IS SUFFICIENT THAT A FEW LOW TOPPED THUNDERSTORMS ARE
POSSIBLE TOMORROW OVER THE NORTHERN WATERS AND ADJACENT COASTAL
SECTIONS...WITH SOME SHOWERS POSSIBLY GENERATING SMALL HAIL.
BUFKIT PROFILES SHOW CONTINUED SATURATION IN THE DENDRITIC GROWTH
ZONE THROUGH MOST OF SATURDAY...SO SNOW WILL LIKELY ADVERSELY
AFFECT TRAVEL OVER MANY PASSES BY TOMORROW. SHOWERS SHOULD BEGIN
TO DIMINISH TOMORROW NIGHT INTO SUNDAY...WITH DRY WEATHER BRIEFLY
RETURNING TO THE REGION SUNDAY NIGHT THROUGH TUESDAY MORNING. WE
BUMPED UP POPS A LITTLE FOR THE SUBSEQUENT SYSTEM FOR THE MIDWEEK
PERIOD...AND GENERALLY KEPT POPS AT OR ABOVE CLIMATOLOGY FOR MUCH
OF THE REMAINDER OF THE FORECAST. BURGER

&&

.AVIATION...VFR CONDS FOR MOST OF TODAY THOUGH KCEC ALREADY DROPPED
BRIEFLY TO MVFR. LOOKING FOR RAIN TO BEGIN IN KCEC AND KACV IN MID
TO LATE AFTN WITH CIGS DROPPING TO MVFR AND THEN SPREADING SOUTH AND
EAST INTO WEAVERVILLE AND UKIAH BY MIDNIGHT. DEAN

&&

.MARINE...SOUTHERLY WINDS CONTINUE TO INCREASE AND ARE A LITTLE
STRONGER THAN MODELS HAVE FORECASTED. STILL LOOKING FOR FRONT TO
MOVE INTO NW WATERS JUST BEFORE SUNSET TODAY AND FINALLY MOVE PAST
PT ARENA ABOUT 4AM SAT. LOW END GALE GUSTS AHEAD OF FRONT IN
NORTHERN OUTER WATERS FOR ABOUT A 6 HOUR PERIOD FROM NOON TODAY TO
ABOUT 7PM TONIGHT BUT WILL NOT ISSUE WARNING AS EVENT IS SHORT-LIVED
AND AREAL COVERAGE OF GUSTS STILL MARGINAL. SECOND VERY WEAK SURFACE
TROUGH MOVES THROUGH SAT AND THEN HIGH BUILDS WITH WINDS SWITCHING
TO NW SAT NIGHT INTO SUNDAY. WARM FRONT MOVES INTO THE WATERS OF THE
PAC NW MON AND WINDS WEAKEN AND SHIFT TO THE SOUTH. TIMING OF COLD
FRONT FOR TUE (NOV 30) IS IN QUESTION. EC IS FASTER WITH STRONGEST
WINDS LATE MON NIGHT-TUE MORNING WHILE GFS SLIGHTLY SLOWER WITH
STRONGEST WINDS MORE MID DAY TUE. STRONGEST WIND SPEEDS FOR BOTH
MODELS ABOUT SAME WITH 30KT IN ZONE 470 AND MORE 15-20KT IN ZONE 450
AND 10 TO 15 KT IN 455.

FOR THE SEAS...NW SWELL FROM WINDS ON BACKSIDE OF COLD FRONT WILL
MOVE INTO WATERS TONIGHT AND WILL PEAK NEAR NEAR 12-13 FT SAT NIGHT
THEN SLOWLY SUBSIDE TO ABOUT 4 FT BY TUE (NOV 30). NEXT SWELL TRAIN
RAPIDLY BUILDS ON WED. DEAN
