AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
320 PM PST TUE DEC 29 2015

.SYNOPSIS...ANOTHER STORM SYSTEM WILL BRING A BRIEF PERIOD OF
RAIN AND MOUNTAIN SNOW LATE THIS AFTERNOON THROUGH WEDNESDAY
MORNING BEFORE HIGH PRESSURE RETURNS FOR THE REMAINDER OF THE
WEEK.

&&

.SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)...A WEAK SHORT WAVE
WILL MOVE S DOWN THE PACIFIC COAST TONIGHT AND EARLY WEDNESDAY.
CLOUDS WILL INCREASE LATE THIS AFTERNOON AND THIS EVENING AS A
QUICK SHOT OF PRECIPITATION WILL MOVE ACROSS THE AREA. RAINFALL
TOTALS WILL AVERAGE AROUND ONE QUARTER TO ONE THIRD OF AN INCH
WITH HIGHER AMOUNTS IN TERRAIN FAVORED LOCATIONS. SOME 1 TO 2 INCH
SNOWS ARE POSSIBLE ABOVE 2500 FT TONIGHT AND WEDNESDAY MORNING
ACROSS THE UPPER TRINITY RIVER AND N NORTH COAST INTERIOR ZONES.

COLDER OVERNIGHT TEMPERATURES ARE EXPECTED WED NIGHT...BUT READING
SHOULD REMAIN ABOVE HARD FREEZE CRITERIA. PATCHY VALLEY FOG IS
ALSO EXPECTED...WITH SOME FREEZING FOG POSSIBLE ACROSS INTERIOR
VALLEYS. HAVE BUMPED COASTAL TEMPERATURES UP A DEGREE OR TWO IN
THE MID-WEEK PERIOD TO ACCOUNT FOR INCREASING DOWNSLOPING
EASTERLY FLOW. DRY WEATHER IS ANTICIPATED. AFTER A PROLONGEDPERIOD
OF RAIN...THIS WILL BE A GOOD OPPORTUNITY TO COMPLETE OVERDUE
OUTDOOR PROJECTS OR JUST TO GET OUT AND ENJOY THE WEATHER. /SEC

.LONG TERM (SATURDAY THROUGH MONDAY)...THE LOW PRESSURE SYSTEM
UNDERCUTTING THE PACIFIC NORTHWEST RIDGE WILL BEGIN TO SHIFT NORTH
INCREASING CHANCES FOR PRECIPITATION FROM SOUTH TO NORTH THROUGH
EARLY NEXT WEEK. POPS WERE INCREASED SLIGHTLY BUT JUST ABOVE
CLIMO. SOME GUSTY RIDGETOP WINDS WILL BE POSSIBLE OVER THE WEEKEND
AS THIS TYPE OF PATTERN ENHANCES GUSTY EAST FLOW. KML

&&

.AVIATION...AN APPROACHING FRONT WILL BRING LIGHT RAIN TO DEL
NORTE COUNTY LATE THIS AFTERNOON...AROUND 0Z...AND WILL THEN
SLOWLY SPREAD SOUTHWARD. MVFR CONDITIONS ARE EXPECTED TO COME WITH
THE PASSAGE OF THIS FRONT...BUT IT IS POSSIBLE THAT WE COULD SEE
CONDITIONS DETERIORATE DOWN TO IFR AT TIMES FOR COASTAL TERMINALS.
KUKI COULD SEE SOME LIGHT RAIN COME FROM THIS SYSTEM AS WELL.
HOWEVER...THEY WOULD NOT START TO SEE PRECIP UNTIL AFTER 07Z. ONCE
THE FRONT EXITS THE REGION WEDNESDAY MORNING...VFR CONDITIONS WILL
RETURN TO NORTHWEST CA. /KAR

&&

.MARINE...LIGHT TO MODERATE WINDS AND DIMINISHING WAVE HEIGHTS
WILL CONTINUE THROUGH THE AFTERNOON BEFORE A WEAK FRONT INCREASES
SOUTH WINDS TONIGHT. THIS WILL BE A FAIRLY WEAK FRONTAL BOUNDARY
SO EXPECT FRESH WIND GUSTS AROUND 20 KT MOSTLY ACROSS THE NORTHERN
WATERS WITH THE FRONTAL PASSAGE LATER TONIGHT. THE SMALL CRAFT
ADVISORIES FOR THE SOUTHERN WATERS SHOULD EXPIRE LATE THIS EVENING
AS THE SEAS SUBSIDE BUT HAVE EXTENDED THE NORTHERN WATERS DUE TO
GUSTY WINDS THROUGH TONIGHT. RELATIVELY LIGHT NORTH WINDS WILL
PERSIST ON THURSDAY BEFORE AN OFFSHORE FLOW REGIME UNFOLDS OVER
THE WEEKEND. THIS COULD BRING A LIGHT EASTERLY CHOP ACROSS THE
OUTER WATERS. SOUTH-SOUTHEAST WINDS WILL INCREASE FURTHER AS THE
LOW PRESSURE SYSTEM THAT DEVELOPED OVER CENTRAL CALIFORNIA SHIFTS
TO THE NORTH AND TIGHTENS THE COASTAL PRESSURE GRADIENT. FEW GALE
FORCE GUSTS MAY BE POSSIBLE LATE IN THE WEEKEND THROUGH EARLY NEXT
WEEK HOWEVER SMALL CRAFT WINDS SHOULD PREVAIL ACROSS THE FAR OUTER
WATERS. THE SEA STATE WILL GET RELATIVELY LOW WEDNESDAY AND
THURSDAY BEFORE SMALLER NORTHWEST SWELL CAUSES THE SEA STATE TO
BUILD SLIGHTLY FRIDAY INTO THE WEEKEND. NOTE: ENP IS SIGNALING FOR
A LARGE NW SWELL TO IMPACT THE NWCA COAST BY TUESDAY OF NEXT WEEK
BRINGING HIGH SURF TO THE AREA...SOMETHING TO KEEP AN EYE ON. KML

&&

.EKA WATCHES/WARNINGS/ADVISORIES...

     SMALL CRAFT ADVISORY UNTIL MIDNIGHT TONIGHT FOR PZZ450-470.
