AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
300 PM PST TUE DEC 15 2009

.SYNOPSIS...A SLOW MOVING FRONT WILL BRING PERIODS OF MODERATE TO
HEAVY RAIN TO NORTHWEST CALIFORNIA THROUGH THIS EVENING. RAIN AND
WINDS WILL TAPER OFF OVERNIGHT WITH MAINLY SCATTERED SHOWER ACTIVITY
EXPECTED ON WEDNESDAY.

&&

.SHORT TERM DISCUSSION...WATER VAPOR IMAGERY SHOWS THE COLD FRONT
IS JUST ON THE DOOR STEP OF THE COASTAL WATERS AT THIS TIME. RADAR
RETURNS CONTINUE TO SHOW WIDESPREAD RAINFALL AND SNOW TO ELEVATIONS
ABOVE 4000 FEET TO ALL AREAS NORTH OF WILLITS...WHILE MODERATE
WINDS REMAIN CONFINED TO THE COAST AND COASTAL RIDGES. THE FRONT
WILL HANG UP BRIEFLY AT THE COAST WHILE DISSIPATING...THEN MOVE
INLAND THIS EVENING. THE UPPER TROUGH AXIS REMAINS OVER THE CWA
THROUGH THE MORNING HOURS...THUS WILL KEEP THE THREAT OF SHOWERS
IN ALL ZONES TONIGHT AND THE EARLY PORTION OF TOMORROW.  HEIGHTS
BEGIN TO RISE LATER TOMORROW AND THURSDAY WITH A BRIEF AND RELATIVELY
DRY BREAK IN THE WEATHER EXPECTED THROUGH LATE THURSDAY.

LONG TERM DISCUSSION...CONFIDENCE HAS INCREASED FOR A WETTER PD THIS
WEEKEND HEADING INTO MONDAY. GOOD CONTINUITY HAS BEEN OBSERVED FOR
THE LAST SEVERAL RUNS OF THE GFS/GEM...WHICH INDICATE A CONTINUATION
OF THE RECENT TREND OF TRACKING A SFC LOW WELL TO OUR NORTH WITH AN
ASSOCIATED BAND OF COLD FRONTAL PRECIP AFFECTING AT LEAST NRN
PORTIONS OF THE CWA. THE LAST TWO RUNS OF THE EC INDICATE A SIMILAR
SOLN...WHICH INCREASES CONFIDENCE IN THE FCST AND SUBSEQUENTLY
LEAVES THE NAM IN A LAND OF ITS OWN FOR NOW. CONFIDENCE IS FAIRLY
HIGH FOR A CHANGE...AS THE SAME SUITE OF MODELS DEPICT A SIMILAR
EVOLUTION FOR ANOTHER SYSTEM LATE SUN INTO MONDAY FOLLOWED BY YET
ANOTHER PERIOD OF HIGH AMPLITUDE RIDGING ON THE WEST COAST.
DEPENDING ON THE EVOLUTION OF THIS PATTERN THERE WILL BE POTENTIAL
FOR A SOUTHERN-DISPLACED STORM TRACK THE EXACT LOCATION OF WHICH IS
WORTH KEEPING AN EYE ON. WITH A SECOND ROUND OF MJO RELATED
CONVECTION PROGGED TO GET GOING...PERHAPS THINGS WILL EVENTUALLY GET
INTERESTING BEYOND THE CURRENT FCST PD. CLARK

&&

.AVIATION...A STORM SYSTEM CROSSING THE REGION WILL BRING CONTINUED
PERIODS OF RAIN AND WIND THROUGH THIS EVENING. WHILE CIGS WILL
REMAIN MOSTLY VFR AND HIGH MVFR THROUGH THE PERIOD...VSBY WILL AT
TIMES BE REDUCED TO LOW MVFR IN MODERATE TO HEAVY RAIN SHOWERS. THE
STORM WILL MOVE SOUTH AND EAST ACROSS THE AREA TONIGHT...SO THE
EMPHASIS OF HEAVIER RAIN WILL SHIFT SOUTH TOWARD UKI AND ADJACENT
AREAS LATE TONIGHT INTO EARLY WEDNESDAY. CMC

&&

.MARINE...GALE CONDITIONS WILL CONTINUE OVER THE WATERS THROUGH LATE
THIS EVENING PER RUC13 GUIDANCE...WHICH KEEPS STRONGER WINDS GOING A
FEW HOURS LONGER THAN THE NAM OR GFS. BUOY DATA INDICATES WIND WAVES
CLOSE TO 18 FT OR HIGHER OFFSHORE TODAY...SO BUMPED UP WAVE HEIGHTS
IN THE GRIDS ACCORDINGLY. AFTER AROUND MIDNIGHT THE GRADIENT WILL
RELAX AND BOTH WINDS AND SHORT PERIOD SEAS WILL RAMP DOWN FAIRLY
QUICKLY. AT THE SAME TIME...A W SWELL FROM AN OFFSHORE LOW WILL
BEGIN TO BUILD INTO THE WATERS...SO THAT THE LARGE SHORT PERIOD
WAVES WILL BE REPLACED BY A LONGER PERIOD SWELL NEAR 13 FEET. WINDS
ARE EXPECTED TO REMAIN LIGHT TO MODERATE AND SOUTHERLY THROUGH THE
WEEKEND...AS LOW PRESSURE REMAINS OFFSHORE. CMC
