AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
305 PM PDT SUN APR 12 2009

.SYNOPSIS...A COLD FRONT WILL BRING LIGHT RAIN NORTH OF CAPE
MENDOCINO TONIGHT. A FEW LINGERING SHOWERS WILL CONTINUE NORTH OF
TRINIDAD THROUGH TUESDAY NIGHT. DRY WEATHER IS EXPECTED WEDNESDAY
THROUGH THE END OF THE WEEK.

&&

.DISCUSSION...SATELLITE IMAGERY SHOWS CLOUDS INCREASING ACROSS
NORTHWEST CALIFORNIA AS A COLD FRONT OFFSHORE MOVES CLOSER TO THE
COAST. THE FRONT WILL BRING LIGHT RAIN TO AREAS NORTH OF CAPE
MENDOCINO TONIGHT. THE RAIN WILL QUICKLY COME TO AN END BY MORNING
AS THE FRONT MOVES TO OUR EAST. TOTAL RAINFALL AMOUNTS WILL
GENERALLY BE UNDER 0.25 INCH WITH LOCATIONS SOUTH OF CAPE
MENDOCINO PROBABLY NOT RECEIVING ANY RAIN.

A COLD UPPER LEVEL LOW WILL DIVE DOWN FROM THE PACIFIC NORTHWEST
AND MOVE OVER US ON TUESDAY. THE MODELS CONTINUE TO BE IN GOOD
AGREEMENT AND STILL SHOW THE CHANCE OF SHOWERS LINGERING AROUND
THROUGH TUESDAY NIGHT OVER DEL NORTE COUNTY. THE LOW IS ALSO VERY
COLD AND WILL LOWER SNOW LEVELS TO ABOUT 1500 FT TO NORTHERN
SECTIONS ON TUESDAY. BUT THERE IS VERY LITTLE MOISTURE WITH THIS
LOW SO ANY SNOW THAT DOES FALL WILL NOT AMOUNT TO MUCH.

THE COLD AIR WILL ALSO BRING THE POTENTIAL FOR FROST/FREEZE ISSUES
TUESDAY AND WEDNESDAY MORNINGS. THIS WILL BE MONITORED OVER THE
UPCOMING SHIFTS.

MODELS ARE CONSISTENT IN SHOWING RIDGING OVER THE WEST COAST
WEDNESDAY THROUGH NEXT WEEKEND...WITH A DRY FORECAST ALL THE WAY
THROUGH THE EXTENDED PERIODS. STROZ

&&

.AVIATION...A MIX OF VFR AND MVFR FLYING CONDITIONS ALONG THE
COAST WILL DETERIORATE OVERNIGHT AS A COLD FRONT SWEEPS ACROSS
THE AREA. LIGHT RAIN NORTH OF CAPE MENDOCINO DEVELOPING DURING
THE EVENING WILL SEND FLIGHT CONDITIONS DOWN TO IFR OR LOW-END
MVFR. VFR CONDITIONS WILL PERSIST FOR SOUTHERN INTERIOR AREAS
OVERNIGHT. BURGER

&&

.MARINE...A FAIRLY COMPLEX FORECAST LIES AHEAD. THE FORERUNNERS TO
LONG PERIOD WNW SWELL ARRIVED EARLIER TODAY...WITH PERIODS RUNNING
AROUND 19 SEC IN THE NORTHERN WATERS. THIS LONG PERIOD SWELL WILL
BUILD OVERNIGHT TO AROUND 10 FEET...NECESSITATING AN ADVISORY FOR
SEAS STATING THIS EVENING FOR NORTHERN WATERS AND LAGGING A FEW
HOURS IN THE SOUTH. COLD FRONTAL PASSAGE IS SLATED FOR LATER
TONIGHT...WITH NORTHERLY WINDS EXPECTED TO KICK UP SHORTLY
THEREAFTER. BY DAYBREAK MONDAY...SOUTHERN WATERS SHOULD BE SEEING
GUSTS TO AROUND 25 KT WITH THOSE WINDS EXPANDING TO THE NORTHERN
WATERS BY AFTERNOON. WE UPGRADED THE GALE WATCH TO A WARNING FOR THE
SOUTHERN WATERS AND BUMPED UP ITS EFFECTIVE TIME BY A FEW HOURS AS
GUSTS TO 35 KT ARE EXPECTED TO DEVELOP BY LATE MONDAY AFTERNOON.
THESE WINDS ACTING ON THE SEAS WILL PRODUCE ADDITIONAL WIND
WAVE/FRESH SWELL OF AROUND 10 FT WHICH WILL MAKE FOR VERY HAZARDOUS
AND CONFUSED SEAS. WINDS AND SEAS WILL SLOWLY DIMINISH FROM NORTH TO
SOUTH TUESDAY NIGHT INTO WEDNESDAY. BURGER
