Area forecast discussion, Dec 4, 3:45 PM PST, 10 hours 21 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
345 PM PST TUE DEC 4 2007

.SYNOPSIS...DRY WEATHER WILL CONTINUE THROUGH WEDNESDAY AS WEAK HIGH
PRESSURE REMAINS OVER THE REGION.  A COLD FRONT APPROACHING THE
COAST WILL LIKELY SPREAD RAIN OVER THE AREA THURSDAY AFTERNOON
THROUGH FRIDAY MORNING.  STRONG HIGH PRESSURE BUILDING INTO THE WEST
COAST OVER THE WEEKEND WILL BRING A RETURN TO DRY WEATHER ALONG WITH
BREEZY NORTHERLY WINDS.

&&

.DISCUSSION...SATELLITE IMAGERY SHOWS HIGH CLOUDS STREAMING OVER THE
NORTHERN HALF OF THE GOLDEN STATE AS THE PATTERN SHIFTS TO A MORE
ZONAL FLOW.  A SHORTWAVE SHOWS UP ON IR/WV IMAGERY MOVING EAST
NORTHEAST AND NEARING 145W.  MODELS INITIALIZE FAIRLY WELL ON THIS
FEATURE...BUT INDICATE THAT IT WILL DISSIPATE TONIGHT.  ANOTHER
SHORTWAVE CURRENTLY NEAR 155W IS EXPECTED TO CONTINUE MOVING
EASTWARD THROUGH THURSDAY AND DIG INTO THE WEST COAST THROUGH FRIDAY
MORNING.  AS THE VORT MAX AND THE ASSOCIATED COLD FRONT MOVE ONSHORE
THURSDAY...RAIN WILL SPREAD ACROSS THE AREA.  ALTHOUGH RAIN IS
LIKELY ACROSS THE ENTIRE CWA THURSDAY AFTERNOON...RAINFALL TOTALS DO
NOT APPEAR TOO IMPRESSIVE AT THE MOMENT.

HIGH PRESSURE BUILDING OVER THE WEST COAST WILL COMBINE WITH LOW
PRESSURE OVER THE GREAT BASIN TO TIGHTEN THE PRESSURE GRADIENT AND
CAUSE BREEZY NORTH WINDS SATURDAY INTO SUNDAY MORNING.  CLEARING
SKIES AND COOLER...DRIER AIR WILL ALLOW OVERNIGHT LOWS ALONG THE
COAST TO DIP BELOW AVERAGE WITH HIGHS REMAINING NEAR NORMAL.
RIDGING WILL REMAIN IN PLACE OVER THE EASTERN PACIFIC THROUGH THE
WEEKEND.  IN THE EXTENDED PERIOD...MODEL DIFFERENCE MAKE THINGS A
LITTLE TRICKIER.  BOTH THE GFS AND ECMWF INDICATE A FRONT MOVING
ONTO THE WEST COAST TUESDAY.  THE 12Z RUNS OF BOTH MODELS SHOWED
RAIN IN THE EKA CWA...BUT THE 18Z GFS SHOWS THE FRONT DISSIPATING
BEFORE REACHING THE COAST WITH NO RAIN IN NORTHERN CALIFORNIA.  FOR
NOW...WILL CONTINUE WITH LOW POPS FOR TUESDAY WITH THE BEST CHANCE
OF RAIN IN THE NORTHERN PORTION OF THE AREA. KL

&&

.AVIATION...HIGH PRESSURE WILL BUILD OVER THE REGION TONIGHT. THIS
WILL MEAN CALM TO LIGHT AND VARIABLE WINDS TONIGHT INTO WEDNESDAY
MORNING WHICH WILL ENHANCE THE DEVELOPMENT OF FOG AND LOW CEILINGS
ALONG THE COAST. INLAND...DUE TO THE MOISTURE FROM THE RECENT HEAVY
RAIN, EXPECT AREAS OF VALLEY FOG AND STRATUS CEILINGS TO DEVELOP
AROUND MIDNIGHT. KENNEDY

&&

.MARINE...LARGE WEST SWELL, ABEIT SUBSIDING, WILL CONTINUE TO
PROPAGATE THROUGH THE COASTAL WATERS TONIGHT. THE SWELL PEAKED AT 26
FEET AT BUOY 22 AT 17Z THIS MORNING AND AT 25 FEET AT BUOY 14 AT
19Z. THE SWELL IS EXPECTED TO CONTINUE TO SUBSIDE AND WILL BE BELOW
18 FEET BY MIDDAY WEDNESDAY AND NEAR 10 FEET ON THURSDAY. THE NEXT
FRONTAL SYSTEM WILL MOVE ACROSS THE WATERS ON THURSDAY. AHEAD OF THE
FRONT EXPECT SOUTH WINDS TO REACH SMALL CRAFT CRITERIA AND THEN
BEHIND THE FRONT THE WINDS SHIFT TO THE NORTH AND WILL WILL REACH
GALE FORCE. THE SWELL WILL BUILD TO NEAR 15 FEET. KENNEDY
