AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
216 PM PST SAT DEC 12 2009

.SYNOPSIS...A LOW PRESSURE SYSTEM WILL CONTINUE TO BRING MORE RAIN
AND HIGHER ELEVATION SNOW TO THE REGION THIS EVENING. A FEW
THUNDERSTORMS ARE POSSIBLE. SHOWERS WILL SLOWLY DIMINISH SUNDAY
INTO MONDAY AS WEAK HIGH PRESSURE MOVES OVER NORTHERN CALIFORNIA.

&&

.SHORT TERM...MAIN FORECAST FOCUS IS ONGOING CONVECTIVE/RAIN/SNOW
EVENT. EUREKA FORECAST AREA IS CURRENTLY UNDER DEFORMATION ZONE
ALOFT...AS MAIN UPPER JET AXIS DIVES EAST ACROSS THE CENTRAL CA
COAST SOUTH OF MAIN LOW. ALTHOUGH THIS JET PATTERN SHOULD RESULT
IN AN EASTWARD PROGRESSION OF THE LOW...LOW LEVEL SOUTHERLY JET
AHEAD OF THE SFC LOW WILL FIRST RESULT IN AXIS OF STRONG LIFT TO
CROSS THE SOUTHERN PORTION OF FA THROUGH THIS EVENING. THIS
RESULTANT LIFT IS ALSO SEEN IN SLOPING 2-D FGEN FORCING...ALONG
WITH OMEGA RESPONSE IN THE LOWER TROP. THEREFORE SHOULD CONTINUE
TO SEE BANDS OF PRECIP PUSH NORTHEAST AND PIVOT ACROSS THROUGH
MUCH OF THE FA THROUGH THIS EVENING. ALSO OF CONCERN THIS
AFT/EVN...IS INSTABILITY AXIS SHOWN IN THE FORM OF A CLEAR DRY
SLOTS ON VISIBLE SATELLITE IMAGERY OVER THE OUTER WATERS. LATEST
SPC MESOANALYSIS SHOWS UP TO A FEW HUNDRED J/KG OF MUCAPE WITH
THIS AREA...MAKING TSTMS A CONTINUED POSSIBILITY. PREVIOUS
FORECASTS LOOK TO HAVE A GOOD HANDLE ON SNOW LEVELS AND SNOW
AMOUNTS THROUGH TONIGHT. LATEST MESOWEST OBSERVATIONS PLACE
FREEZING LEVEL RIGHT AROUND 5000FT. SPOTTY ACCUMULATIONS OF 4 TO 6
INCHES WILL BE POSSIBLE AT ELEVATIONS ABOVE 5500 FT...WITH
WIDESPREAD 1 TO 3 INCHES EXPECTED FOR THE 3.5 TO 5 KFT RANGE
THROUGH THIS EVENING. WILL CONTINUE TO HIGHLIGHT THIS EXPECTED
SNOWFALL WITH ONGOING SPECIAL WEATHER STATEMENT.

THE UPPER TROUGH AND ASSOCIATED SFC LOW WILL PUSH EAST ACROSS THE
NORTH COAST OVERNIGHT TONIGHT. COLD POOL ALOFT WILL LIKELY RESULT
CONTINUING SHOWERS THROUGH SUNDAY. ADDITIONAL QPF AMOUNTS ARE
RELATIVELY LIGHT AND RANGE UP TO QUARTER INCH FOR SUNDAY. BRIEF
RIDGING ALOFT WILL BRING A SHORT BREAK IN RAINFALL FOR SUNDAY
NIGHT INTO MONDAY. MODELS ARE A BIT DIFFERENT ON THE TIMING OF THE
ONSET OF PRECIPITATION WITH NEXT SHORT WAVE TROUGH SYSTEM LIFT
NORTHEAST ON THE BACKSIDE OF UPPER RIDGE. GOOD MOISTURE
AVAILABILITY EXISTS AHEAD OF THIS SYSTEM WITH LONG SOUTHWESTERLY
TRAJECTORY. AS SYSTEM LIFT NORTHEAST...LOW LEVEL BOUNDARY BECOME
ORIENTED NEARLY PARALLEL TO UPPER FLOW PATTERN. HENRY

.LONG TERM...TUES THRU SAT. AS AN UPPER TROUGH ROTATES INTO BC THE
CANADIAN/GFS/EC DEVELOP A SFC LOW WELL TO OUR N WITH THE ASSOC COLD
FRONT BRINGING RAIN TO THE AREA IN THE TUES-WED TIME FRAME. Q
FORCING FOR ASCENT IN AN H7-H3 LAYER CONFIRMS THAT THE BEST FORCING
FOR ASCENT WILL REMAIN WELL TO OUR N...ALTHOUGH NRN PORTIONS OF THE
CWA MAY SEE SOME UPPER UPPER SUPPORT FROM THE BACK END OF A 140KT
250MB JET STREAK. BRISK S WINDS AHEAD OF THE FRONT WILL RESULT IN
HEAVIER PRECIP IN LOCALLY FAVORED AREAS WITH THE HUMBOLDT BAY REGION
LIKELY TO SEE INCREASED SHADOWING. PRIMARY CHANGE WAS TO BUMP UP
POPS FOR TUE-WED IN THE SOUTHERN ZONES AS GFS/EC AND 84HR NAM
SUGGEST DECENT QPF FOR ALL ZONES. AFTER A BRIEF PD OF UPPER RIDGING
THURS-FRI ANOTHER TROUGH WILL DEEPEN OVER THE EASTERN PAC WITH ASSOC
COLD FRONTAL PRECIP AFFECTING THE CWA SAT AFTN INTO SUNDAY WITH THE
TROUGH AXIS SWINGING THRU SOMETIME EARLY NEXT WEEK. CLARK

INLAND AND WEAK HIGH PRESSURE MOVES OVER THE REGION. THE NEXT MARINE
THREAT IS AN INCREASE OF SOUTH WINDS AND BUILDING SEAS MONDAY
AFTERNOON AHEAD OF AN APPROACHING FRONT. THE WINDS WILL BE STRONGEST
OVER THE OUTER WATERS WITH GALES EXPECTED MONDAY AFTERNOON THROUGH
