AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
254 PM PST WED DEC 30 2015

.SYNOPSIS... DRY AND COLD CONDITIONS WILL CONTINUE ACROSS THE
REGION THROUGH SATURDAY.

&&

.SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)...DRY CONDITIONS,
MOSTLY CLEAR SKIES AND COLD TEMPERATURES WILL CONTINUE ACROSS THE
REGION THROUGH SATURDAY. LIGHT OFFSHORE WINDS WILL DEVELOP ACROSS
THE AREA TONIGHT AND PERSIST THROUGH FRIDAY. TEMPERATURES ACROSS
COASTAL AREAS WILL FALL TO NEAR 30 TO THE MIDDLE 30'S THE NEXT FEW
NIGHTS. TEMPERATURES ACROSS INLAND AREAS WILL FALL INTO THE LOWER
30'S AND 20'S THE NEXT FEW NIGHTS. SOME VALLEY FOG MAY DEVELOP IN
VALLEYS WITH LIGHT TO CALM WINDS. TEMPERATURES WILL INCREASE
SLIGHTLY SATURDAY AS AN OFFSHORE LOW PRESSURE SYSTEM SHIFTS THE
WINDS TO THE SOUTH.

.LONG TERM (SUNDAY THROUGH TUESDAY)...A LOW PRESSURE SYSTEM LOCATED
OFF THE CALIFORNIA COAST WILL LIFT NORTHWARD INCREASING THE CHANCE
FOR PRECIPITATION SUNDAY. A WARM FRONTAL FEATURE COULD BRING LIGHT
RAIN NORTH OF CAPE MENDOCINO EARLY SUNDAY MORNING WITH THE MAIN
FRONTAL BAND FIRST IMPACTING MENDOCINO COUNTY AND MOVING
NORTHEASTWARD. THE GFS AND ECMWF ARE IN RELATIVELY GOOD AGREEMENT
JUST CONTAINING SOME SUBTLE DIFFERENCES IN THE TIMING AND MAGNITUDE
OF THE RAINFALL ON SUNDAY. STORMY WEATHER WILL CONTINUE EARLY NEXT
WEEK WITH ANOTHER FRONT PROGGED TO BRING WIDESPREAD RAIN TUESDAY AND
PERSISTING SHOWER ACTIVITY WEDNESDAY AS THE LOW CENTER SHIFTS
OVERHEAD. THEN MODELS SHOW RIDGING WHICH COULD MEAN DRY WEATHER FOR
LATE NEXT WEEK. THIS IS STILL A BROAD-BRUSH OUTLOOK AND WE WILL FINE
TUNE THE TIMING AND MAGNITUDE OF RAINFALL OVER THE NEXT FEW DAYS.
KML

&&

.AVIATION...CLOUDINESS PERSISTED ACROSS INTERIOR AREAS TODAY WHILE
SUBSIDENCE OFFSHORE HELPED TO KEEP COASTAL REGIONS MOSTLY CLEAR
THROUGH THE AFTERNOON. OFFSHORE FLOW TONIGHT SHOULD HELP KEEP MOSTLY
VFR CONDITIONS AT KCEC AND KACV WITH MINIMAL MVFR POSSIBLE WHERE
PATCHY CLOUDS DEVELOP ALONG POCKETS OF THE COAST. EXPECT CLOUD
COVER TO RETURN OVER INTERIOR VALLEYS AGAIN TONIGHT. THERE IS
UNCERTAINTY IN THE SEVERITY OF CEILING AND VISIBILITY REDUCTIONS BUT
EXPECT KUKI TO OBSERVE CONDITIONS SIMILAR TO LAST NIGHT. KML

&&

.MARINE...BROAD SURFACE RIDGING ACROSS THE WESTERN UNITED STATES
WILL MAINTAIN A WEAKENED PRESSURE GRADIENT ACROSS THE COASTAL WATERS
OVER THE NEXT FEW DAYS MEANING GENTLE TO MODERATE WINDS.
SOUTH-SOUTHEAST WINDS WILL DEVELOP FRIDAY AND SATURDAY AHEAD OF THE
NEXT APPROACHING LOW PRESSURE SYSTEM THAT WILL BRING RAIN TO THE
WATERS ON SUNDAY. THE STRONGEST WINDS WILL BE ACROSS THE FAR OUTER
WATERS WITH SMALL CRAFT ADVISORIES LIKELY ON SUNDAY. FOR THE WAVES,
MULTIPLE SMALL NW SWELLS WILL MAINTAIN 6 TO 8 FT SEAS THROUGH FRIDAY
WITH A LARGER SWELL ARRIVING SATURDAY NIGHT. THIS, IN ADDITION TO
BUILDING SHORT PERIOD WAVES WILL BRING THE SEA STATE NEAR 10 FT. ENP
IS SHOWING THE POTENTIAL FOR SNEAKER WAVES LATE SATURDAY AFTERNOON
AND EVENING. THIS WILL BE SOMETHING TO KEEP AN EYE ON OVER THE NEXT
FEW DAYS. WAVE MODELS THEN SHOW INDICATIONS FOR A MUCH LARGER SWELL
TO IMPACT THE NORTHWEST CALIFORNIA COAST EARLY NEXT WEEK BRINGING
NEARLY 20 FT SEAS AND HIGH SURF CONDITIONS. KML

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...NONE.
