AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
612 PM PST MON DEC 27 2010

.SYNOPSIS...MOISTURE AHEAD OF A COLD FRONT WILL BRING HEAVY RAIN AND
HIGH ELEVATION SNOW TO THE REGION TONIGHT THROUGH TUESDAY NIGHT. THE
FRONT WILL CROSS THE REGION WEDNESDAY MORNING...WITH SNOW LEVELS
FALLING TO AS LOW AS 1000 FEET BY WEDNESDAY NIGHT.

&&

.UPDATE...A QUICK UPDATE TO THE FORECAST INCLUDES INCREASING POPS
ACROSS THE CWA FOR THE TONIGHT PERIOD...AS RAIN HAS ALREADY SPREAD
INTO THE REDWOOD COAST AND NORTH COAST INTERIOR ZONES. KBHX SHOWS
MODERATE RAIN OVER THE WATERS NEAR AND NORTH OF CAPE
MENDOCINO...SPREADING INLAND SOUTH OF TRINIDAD. NO OTHER CHANGES
WERE MADE AS FORECAST IS ON TRACK FOR SIGNIFICANT PRECIP EVENT
SPREADING FROM NORTHWEST TO SOUTH AND EAST ACROSS THE CWA TONIGHT
INTO TUESDAY. CILIBERTI.

&&

.DISCUSSION...SEVERAL FORECAST ISSUES PRESENT THEMSELVES OVER THE
NEXT COUPLE OF DAYS INCLUDING SNOW AMOUNTS/LEVELS...HEAVY RAINFALL
AND THE POSSIBILITY OF BOTH SMALL STREAM AND MAIN STEM FLOODING.

INCOMING STORM SYSTEM STILL TAKING SHAPE WELL OFFSHORE WITH AN
IMPRESSIVE FEED OF TROPICAL MOISTURE EXTENDING FROM NORTHERN
CALIFORNIA DOWN TO THE TROPICS SOUTH AND WEST OF THE HAWAIIAN
ISLANDS. SHORT TERM MODEL SOLUTIONS HAVE PUSHED BACK THE START
TIME OF STEADY RAINS...BUT MOST AREAS ALONG THE REDWOOD COAST
SHOULD RECEIVE MEASURABLE RAIN BY DAYBREAK. AREAS FARTHER EAST AND
SOUTH WILL FOLLOW DURING THE MORNING HOURS TUESDAY. SOUTH WINDS
WILL ALSO BECOME LOCALLY GUSTY TOWARDS DAYBREAK NORTH OF
TRINIDAD...WITH GUSTS UP TO 35 MPH POSSIBLE LATE TONIGHT AND EARLY
TOMORROW.

PRECIPITABLE WATER AXIS SETS UP RIGHT ACROSS THE FORECAST AREA
TUESDAY AHEAD OF THE FRONT...WITH RAIN LIKELY TO BE LOCALLY HEAVY.
WIDESPREAD RAINFALL AMOUNTS OF 1 TO 3 INCHES ARE LIKELY...WITH
LOCALIZED AMOUNTS OF 5+ INCHES. IN COORDINATION WITH THE
RFC...GENERALLY WEIGHTED QPF VALUES MORE TOWARDS THE EURO AS
OPPOSED TO THE WETTER GFS...BUT THESE ARE STILL IMPRESSIVE. SMALL
STREAM AND URBAN FLOODING LOOKS LIKE A GOOD POSSIBILITY...AND
HEADLINES MAY BE REQUIRED. SEVERAL MAIN STEM RIVERS MAY REACH
MONITOR STAGE OR POSSIBLY FLOOD STAGE TUESDAY NIGHT OR WEDNESDAY.
SEE HYDROLOGY STATEMENT BELOW FOR MORE DETAILS. THE OTHER ISSUE IS
SNOW. SNOWFALL AMOUNTS AT THE HIGHEST ELEVATIONS WILL UNDOUBTEDLY
REACH WARNING CRITERIA...BUT PER COORDINATION WITH NEIGHBORING
WFO/S AND AN ASSESSMENT OF LIKELY IMPACTS...A WINTER WEATHER
ADVISORY WILL INSTEAD BE ISSUED. AS THE COLD FRONT MOVES THROUGH
THE AREA LATE TUESDAY NIGHT...MUCH COLDER AIR WILL SPILL INTO THE
AREA WITH SNOW LEVELS FALLING AROUND 1500 FEET DURING THE DAY
WEDNESDAY. PRECIPITATION WILL CERTAINLY BE ON A DOWNWARD TREND BY
THEN BUT LOW SNOW LEVELS AND THE POTENTIAL OF A COUPLE/FEW INCHES
OF SNOW MAY REQUIRE EXTENSION OF THE WINTER WEATHER ADVISORY TO
LOWER ELEVATIONS/OTHER ZONES. THE REMAINDER OF THE FORECAST WAS
LEFT ESSENTIALLY UNCHANGED WITH THE PRECIPITATION THREAT
DIMINISHING THURSDAY INTO FRIDAY. CONSIDERABLE MODEL UNCERTAINTY
IN PERIODS BEYOND BASICALLY SUGGESTED A NEAR CLIMATOLOGICAL
APPROACH TO POPS. BURGER

&&

.AVIATION...CONDITIONS WILL BE DETERIORATING ACROSS THE REGION
THROUGH THE EVENING HOURS WITH RAIN EXPANDING FROM NORTH TO SOUTH
ALONG THE REDWOOD COASTAL AREA BY LATE EVENING. RAIN WILL BE
STRATIFORM IN NATURE WITHOUT EXCESSIVELY STRONG CONVECTIVE GUSTS.
WINDS AT KCEC AND KACV MAY BE GUSTY FROM TIME TO TIME OVERNIGHT.
VSBYS WILL REMAIN IN THE VFR CATEGORY THROUGH THE NIGHT EXCEPT IN
ISOLATED POCKETS OF HEAVIER RAIN WHERE VISIBILITIES MAY FALL TO
AROUND 4 SM...HAVE INCLUDED THIS IN A TEMPO GROUP FOR CEC. THE
POSSIBILITY ALSO EXISTS FOR THIS TO HAPPEN AT ACV...BUT CHANCES ARE
LESS IN THIS LOCATION. CIGS MAY DROP AS LOW AS 2500 FT THROUGH THE
COURSE OF THE NIGHT ALONG THE COAST...BUT SHOULD NOT DROP INTO IFR
AT ALL. CONDITIONS WILL REMAIN IN VFR NEAR KUKI...AND RAINS SHOULD
HOLD OFF IN MENDOCINO COUNTY UNTIL THE EARLY MORNING HOURS. MSB

&&

.MARINE...THE PRESSURE GRADIENT WILL BE TIGHTENING THIS EVENING
CAUSING INCREASING WINDS AND BUILDING SEAS. WINDS WILL REACH NEAR
GALE TO GALE FORCE NORTH OF CAPE MENDOCINO AND STRONG TO NEAR GALE
SOUTH OF THE CAPE WHILE SHORT PERIOD SEAS WILL BUILD IN RESPONSE TO
THE INCREASED WINDS. A MODERATE NW SWELL WILL CONTINUE THROUGH TUE.
A COLD FRONT WILL CROSS THE AREA TUE NIGHT AND WILL BE FOLLOWED BY A
SURGE OF NORTHERLY WINDS AS HIGH PRESSURE PUSHES IN BEHIND THE
FRONT. CONFIDENCE IN THE STRENGTH OF THIS SURGE IS LOW AS THE MODEL
ARE NOT IN AGREEMENT AND HAVE BEEN BACKING OFF OVER THE LAST FEW
MODEL RUNS. THE STRENGTH OF THE WINDS WILL BE DEPENDENT UPON HOW THE
RIDGE SETS UP OVER THE AREA. 12Z MODEL RUNS TODAY ARE TAKING THE
UPPER LOW/TROUGH FURTHER TO THE EAST AND ALLOWING THE RIDGE TO SET
UP CLOSER TO THE COAST. IF THE RIDGE ENDS UP OVER NW CALIFORNIA,
THEN WINDS WILL BE LIGHTER THAN FORECAST. HOWEVER, IF THE TROUGH
DIGS INTO THE GREAT BASIN INSTEAD OF THE ROCKIES, GALES COULD BE A
DISTINCT THREAT ACROSS THE WATERS. FOR NOW A GALE WATCH HAS BEEN PUT
OUT TO INDICATE THE POTENTIAL THREAT, BUT CONFIDENCE IS LOW. BEYOND
MIDWEEK WINDS AND SEAS WILL EASE AS THE GRADIENT RELAXES. BFG

&&

.HYDROLOGY...AN 18 TO 24-HOUR WINDOW OF HEAVY PRECIPITATION FROM
EARLY TUESDAY INTO EARLY WEDNESDAY WILL LIKELY RESULT IN
SIGNIFICANT RISES ON MAIN STEM RIVERS. BY LATE TUESDAY NIGHT INTO
WEDNESDAY...HYDROGRAPHS SUGGEST RIVERS CRESTING AT OR ABOVE
MONITOR STAGE FOR THE SMITH RIVER AT DR. FINE BRIDGE...THE EEL
RIVER AT FERNBRIDGE...AND THE RUSSIAN RIVER AT HOPLAND.
ADDITIONALLY...THE LATEST DATA SUGGEST THE NAVARRO RIVER AT
NAVARRO POSSIBLY EXCEEDING FLOOD STATE LATE TUESDAY NIGHT. WE
CONSIDERED ISSUING A FLOOD WATCH FOR THE NAVARRO...BUT TIMING IS
JUST OUTSIDE THE 36-HOUR WINDOW AND THE PROJECTED CREST AT THIS
TIME IS JUST ONE FOOT ABOVE FLOOD STAGE. THE NEXT SET OF MODEL
RUNS WILL FURTHER HELP PIN DOWN TIMING AND ACTUAL STAGE...BUT WE
ELECTED TO ISSUE A FLOOD POTENTIAL OUTLOOK TO HIGHLIGHT THE
EXPECTED RAPID RISES ON ALL MAIN STEM RIVERS. ANOTHER...POSSIBLY
GREATER IMPACT EVENT...WILL BE URBAN AND SMALL STREAM FLOODING.
THIS IS A HIGH LIKELIHOOD GIVEN PROJECTED RAIN RATES AND WILL BE
FURTHER MONITORED AS THE PRECIPITATION EVENT EVOLVES. BURGER
