What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Eureka, CA wrote its last area forecast discussion before this small craft advisory went out at Apr 22, 3:28 PM PDT, 11 hours 46 minutes earlier.
Area forecast discussion, Apr 22, 3:28 PM PDT, 11 hours 46 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
328 PM PDT WED APR 22 2015
.SYNOPSIS...A HIGH PRESSURE SYSTEM HAS PRODUCED BLUSTERY
NORTHERLY WINDS AT THE COAST TODAY. INSTABILITY OVER EASTERN
MENDOCINO COUNTY MAY PRODUCE A FEW LATE DAY THUNDERSTORMS OVER
THE MOUNTAINS.
&&
.DISCUSSION...A HIGH PRESSURE SYSTEM IS BUILDING ACROSS THE REGION
IN THE WAKE OF THE RECENT COLD FRONTAL PASSAGE. A COOLER AND DRIER
AIR MASS WILL RESULT IN LESS CLOUDINESS TONIGHT. NORTHERLY WINDS
WILL BE GUSTY ALONG THE IMMEDIATE COAST THROUGH THIS EVENING AND
ACROSS HIGHER ELEVATIONS. A FEW ISOLATED THUNDERSTORMS MAY DEVELOP
OVER HIGHER ELEVATIONS IN SOUTHEASTERN MENDOCINO COUNTY THROUGH
THE EARLY EVENING HOWEVER CONFIDENCE IS LOW. A MID LEVEL SHORT
WAVE WILL MOVE ACROSS THE AREA ON THURSDAY WHICH WILL PRODUCE
COOLER TEMPERATURES ACROSS THE AREA. THE WAVE WILL MOVE ACROSS
THE AREA THURSDAY NIGHT AND INCREASE CLOUDINESS. THERE IS A SLIGHT
CHANCE OF SHOWERS ACROSS PORTIONS OF THE AREA FRIDAY NIGHT INTO
SATURDAY MORNING. A HIGH PRESSURE RIDGE WILL BUILD ACROSS THE AREA
THIS WEEKEND.
&&
.AVIATION...MOST OF NORTHWEST CALIFORNIA HAS CLEARED OF CLOUD
COVER WITH THE EXCEPTION OF SOME SLOWLY ERODING STRATUS ACROSS
INTERIOR HUMBOLDT. SOME CU HAS DEVELOPED ACROSS THE FAR EASTERN
PERIPHERY OF THE FORECAST AREA WITH SOME ISOLATED STORMS BEYOND THE
EASTERN TRINITY/MENDOCINO COUNTY LINES. ITS POSSIBLE FOR A STORM OR
TWO TO DEVELOP OVER THE TRINITY HORN AND/OR THE MENDOCINO NATIONAL
FOREST BUT THE POSSIBILITY WILL QUICKLY DIMINISH BY NIGHTFALL. GUSTY
WINDS WILL PERSIST LATE THIS AFTERNOON AND EVENING BUT SHOULD
GRADUALLY WEAKEN TONIGHT. THE NORTH COAST WILL HAVE THE GUSTIEST
WINDS ACROSS THE REGION, HOWEVER, THEY SHOULD BE A LITTLE LIGHTER
THAN YESTERDAY NIGHT SINCE THE PRESSURE GRADIENT IS EXPECTED TO
RELAX. WITH ALMOST NO STRATUS IN SIGHT ON THE VISIBLE SATELLITE
IMAGERY EXPECT MOST OF CALIFORNIA TO EXPERIENCE VFR CONDITIONS
OVERNIGHT. HOWEVER, MODELS ONCE AGAIN SHOW HIGHER RH VALUES
DEVELOPING OVER HUMBOLDT BAY TONIGHT SO DO NOT BE SURPRISED TO SEE
SOME MVFR CEILINGS TO DEVELOP TONIGHT.
&&
.MARINE...GALE WARNINGS CONTINUE TODAY AS THE PRESSURE GRADIENT
REMAINS TIGHT ACROSS THE COASTAL WATERS. AN AFTERNOON ASCAT PASS
VERIFIED 30 KT WINDS ACROSS THE WATERS WITH THE HIGHEST WINDS (IN
THE UPPER 30 KT RANGE) FARTHER OFFSHORE. THE TREND TOWARDS
IMPROVEMENT WILL BEGIN LATE TONIGHT AS THE BRITISH COLUMBIA LOW
PRESSURE SYSTEM INTERRUPTS THE PRESSURE GRADIENT BETWEEN THE RIDGE
OF HIGH PRESSURE OFFSHORE AND THE INLAND TROUGH. THIS WILL ALLOW
NORTHERLY WINDS TO DECREASE ON THURSDAY WITH WAVES TO FOLLOW.
IMPROVING CONDITIONS WILL TREND INTO THE WEEKEND HOWEVER ADVISORIES
WILL BE NEEDED TO SUPPLEMENT THE EXPIRING GALES ON THURSDAY. A
LONGER PERIOD SWELL WILL PROPAGATE THROUGH THE WATERS ON FRIDAY AND
BUILD FRIDAY EVENING. THIS WILL MARK THE TRANSITION BETWEEN A WAVE
ENVIRONMENT DOMINATED BY SHORTER PERIOD LOCALLY GENERATED WAVES TO
AN ENVIRONMENT DOMINATED BY LONGER PERIOD WAVE ENERGY. WHAT DOES
THIS MEAN? NOT MUCH FOR THE OPEN OCEAN BUT IT DOES CAUSE SOME
CONCERN FOR SHALLOW WATER SHOALS, THE SURF ZONE, AND THE BEACH. THE
LONGER LULLS BETWEEN THE BREAKING WAVES MAY CAUSE A FALSE SENSE OF
SECURITY FOR THOSE IN OR NEAR THE OCEAN (ESPECIALLY AFTER THE LARGE
SURF WE ARE OBSERVING TODAY). AGAIN, DISCREPANCIES IN THE MODELS
CREATE SOME UNCERTAINTY IN THE CONDITIONS IN SURF/BEACH ZONE ON
FRIDAY BUT IT STILL WARRANTS MENTION. KML
&&
.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...
GALE WARNING UNTIL 3 AM PDT THURSDAY FOR PZZ450-455.
GALE WARNING UNTIL 9 AM PDT THURSDAY FOR PZZ470.
GALE WARNING UNTIL 3 PM PDT THURSDAY FOR PZZ475.
