Hazardous Seas Warning 31, NWS Eureka, CA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
634 PM PDT SUN OCT 6 2013

.SYNOPSIS...A TROUGH WILL MOVE OVER THE PACIFIC NORTHWEST ON
MONDAY AND THEN SLOWLY BUILD OVER NORTHERN CALIFORNIA BY
WEDNESDAY. THIS WILL BRING COOLER TEMPERATURES AND SOME CLOUDS TO
THE COAST.

&&

.UPDATE...HIGH CLOUDS ARE BEGINNING TO SLIDE EAST OF THE AREA
LEAVING MOST LOCATIONS CLEAR. THE COLD FRONT OFF THE COAST SHOULD
BE JUST SLOW ENOUGH TO KEEP TRINITY COUNTY AND MANY OTHER INTERIOR
AREAS CLEAR ENOUGH TO ALLOW FROST TO FORM AGAIN TONIGHT. WENT
AHEAD AND ISSUED A FROST ADVISORY FOR THE VALLEY LOCATIONS OF
TRINITY COUNTY BUT ONLY INCLUDED SOME FROST WORDING IN THE ZONE
AND POINT AND CLICKS FOR OTHER LOCATIONS DUE TO HIGHER
UNCERTAINTY. OTHERWISE THE GOING FORECAST REMAINS ON TRACK AND THE
PREVIOUS DISCUSSION IS INCLUDED BELOW.

&&

.PREV DISCUSSION......ISSUED AT 307 PM PDT...

DISCUSSION...NO MAJOR CHANGES. MODELS ARE IN GOOD AGREEMENT
SHOWING A TROUGH MOVING INTO THE PACIFIC NORTHWEST ON MONDAY AND
THEN HAVING IT SLOWLY BUILD OVER NORTHERN CALIFORNIA BY WEDNESDAY
BEFORE GRADUALLY SHIFTING TO THE EAST BY THE END OF THIS WEEK.
THIS WILL BRING COOLER TEMPERATURES AND THE THREAT OF A FEW
SPRINKLES OR MAYBE A LIGHT SHOWER TO MAINLY DEL NORTE COUNTY
MONDAY AND TUESDAY. THOUGH, QPF SHOULD BE MINIMAL AND MODELS
CONTINUE TO TREND DRIER. AS A RESULT, POPS CONTINUE TO LOWER.
EXPECT COLD NIGHT TIME TEMPERATURES WITH THIS TROUGH AND THE
ASSOCIATED FROST/FREEZE PRODUCTS. KEPT POPS NEAR CLIMO IN THE LONG
RANGE.

AVIATION...VFR IS EXPECTED TO CONTINUE AT ALL AREA AIRPORTS
THROUGH THE NIGHT. MODELS ARE HINTING AT SOME GROUND FOG AT CEC
AND ACV, BUT IT REMAINS VERY DRY ALONG THE COAST THIS AFTERNOON
AND DO NOT REALLY SEE THIS OCCURRING. THAT SAID, HINTING AT IT
WITH 6SM BR FOR A FEW HOURS FROM DAWN TO SUNRISE. VFR SHOULD
PREVAIL MONDAY AS WELL. BFG

MARINE...18Z ASCAT PASS SHOWED SOUTHERLY WINDS OF 5 TO 15 KTS
ACROSS THE OUTER WATERS. AS OF 21Z BUOY OBSERVATIONS REPORTED
WAVES OF 4 TO 6 FT WITH BUOY 46014 REPORTING WINDS OUT OF THE
NORTH. WINDS WILL EVENTUALLY TURN OUT OF THE NORTH AND STRENGTHEN
ACROSS ALL OF THE WATERS OVERNIGHT INTO MONDAY AS A WEAK FRONTAL
SYSTEM MOVES THROUGH THE AREA AND HIGH PRESSURE STRENGTHENS BEHIND
IT. NORTHERLY WINDS WILL RAPIDLY INCREASE ON MONDAY...APPROACHING
GALE FORCE MONDAY NIGHT INTO TUESDAY ACROSS THE OUTER WATERS.
CONTINUED THE SMALL CRAFT ADVISORIES ACROSS THE WATERS MONDAY WITH
A GALE WATCH STARTING ACROSS THE SOUTHERN OUTER WATERS MONDAY
NIGHT AND THE NORTHERN OUTER WATERS TUESDAY MORNING. A LONGER
PERIOD NW SWELL CURRENTLY PROPAGATING THROUGH THE WATERS WILL MIX
WITH BUILDING NORTHERLY WIND DRIVEN SEAS...WITH THE SHORT PERIOD
SEAS DOMINATING THROUGH MIDWEEK. WINDS AND SEAS WILL SUBSIDE LATER
IN THE WEEK. STP
