AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
259 PM PDT MON APR 5 2010

.SYNOPSIS...
SHOWERS WILL PERSIST OVER DEL NORTE AND HUMBOLDT
COUNTIES THROUGH THE LATE EVENING HOURS. LOW CLOUDS AND A BRIEF
PERIOD OF LIGHT RAIN ON TUESDAY MORNING WILL GIVE WAY TO CLEARING
SKIES FOR TUESDAY AFTERNOON. WEDNESDAY WILL BE PLEASANT BEFORE A
WEAK FRONT BRINGS A PERIOD OF RAIN ON THURSDAY.

&&

.DISCUSSION...
FORECAST PROBLEMS IN THE NEAR TERM ARE PRECIP CHANCES OVERNIGHT AND
IN THE EARLY MORNING MAINLY IN THE NORTH AND CHANCES FOR FROST/FRZ IN
THE SOUTH WHERE CLEARING IS MOST LIKELY. PRECIP COVERAGE WILL
INCREASE NEAR THE CA/OR BORDER THIS AFTN AND INTO THE EVE...MAINLY
BEFORE MIDNIGHT...AS A COUPLE BANDS OF SHOWERS MAKE THEIR WAY
ONSHORE FROM THE NORTHWEST. THESE WILL BE GOOD FOR AT LEAST A TENTH
OF AN INCH AT THE COAST AND A QUARTER INCH OR MORE NEAR CEC AND IN
FAVORED TERRAIN. A WEAK/DECAYING FRONT WILL FOLLOW IN THE EARLY
MORNING THAT WILL BRING LOW BL CLOUDS TO THE IMMMEDIATE COAST WITH
THE POTENTIAL TO PRODUCE A COUPLE ADDITIONAL HUNDRETHS BEFORE
CONDITIONS CLEAR UNDER INCREASING SUBSIDENCE AND BUILDING HEIGHTS
ALOFT. WITH PRECIP CONFINED TO NORTHERN AREAS...THERE WILL BE AN
OPPORTUNITY FOR SOUTHERN PORTIONS TO CLEAR OUT SO UPGRADED FRZ WATCH
TO A WARNING AND INCLUDED MENTION PATCHY FROST FOR MOST OF THE MENDO
COAST AND SOUTHERN PORTIONS HUMBOLDT COUNTY WHERE COLD TEMPS WILL BE
LESS WIDESPREAD AND MORE BORDERLINE.

OTHERWISE...ADJUSTED POPS FOR THURSDAY AS THE CWA NORTH OF CAPE
MENDOCINO WILL BE AFFECTED BY THE TAIL END OF A LONG COLD FRONT
ASSOCIATED WITH A LOW WELL TO OUR NORTH. FOR THIS FEATURE...FOLLOWED 12Z
GFS GUIDANCE FOR TIMING. FEW CHANGES MADE TO THE GOING FORECAST
THEREAFTER AS THERE WILL BE A SERIES OF POORLY DEFINED THREATS FOR
PRECIP FOLLOWED BY A DEEP TROUGH PROGGED TO DEVELOP FOR THE WEEKEND.
WHILE THE STRONGEST FORCING WILL LIKELY REMAIN WELL TO OUR
SOUTH...FALLING HEIGHTS AND WEAK EMBEDDED DISTURBANCES WILL BE
SUFFICIENT TO GENERATE PRECIP OVER MUCH OF THE CWA THOUGH TIMING
REMAINS AN UNCERTAINTY. CLARK

&&

.AVIATION...
MAINLY VFR CIGS THIS AFTERNOON ALONG WITH SCT -SHRA.
MVFR CIGS AND SHOWERS TO EXPAND IN COVERAGE NORTH OF KACV THIS
EVENING AND PERSIST MOST OF THE NIGHT. FARTHER SOUTH...PARTIAL
CLEARING SKIES OVERNIGHT WITH WINDS BECOME LIGHT. IFR CIGS ARE
POSSIBLE AT KUKI AROUND 12Z TUE DUE TO RADIATIVE COOLING PROCESSES.

.MARINE...
A WESTERLY SWELL TRAIN WILL CONTINUE TO SUBSIDE OVER THE
NEXT COUPLE OF DAYS. A SMALL CRAFT ADVISORY FOR HAZ SEAS WILL REMAIN
IN EFFECT THROUGH TUE NIGHT AS THIS SWELL DECAYS. WINDS WILL REMAIN
FAIRLY LIGHT (GENERALLY UNDER 15KTS) AND VARIABLE THROUGH WED NIGHT.
A COLD FRONT WILL MOVE THROUGH THE WATERS EARLY THURSDAY WITH NORTH
WINDS RAMPING UP IN ITS WAKE. GALES LOOK LIKE A SURE BET BY THU
AFTERNOON ALONG WITH STEEPENING SEAS. JCA
