AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
341 AM PDT MON JUN 11 2018

.SYNOPSIS...A MORE SUMMER-LIKE PATTERN IS EXPECTED OVER THE NEXT
WEEK AS HIGH PRESSURE ALOFT BUILDS OVER THE REGION. MAINLY DRY
AND WARMER CONDITIONS ARE EXPECTED WITH PLENTIFUL SUNSHINE ACROSS
THE INTERIOR AND A MIX OF SUN AND LOW CLOUDS ALONG THE COAST.

&&

.DISCUSSION...A VERY QUIET WEATHER PATTERN IS SHAPING UP FOR THE
WEEK ACROSS THE REGION. MAIN WEATHER ISSUES WILL BE DEALING WITH
COASTAL MARINE INFLUENCE AND RESULTING CLOUD COVER ALONG WITH
RISING TEMPERATURES ACROSS THE INTERIOR AS SUMMER BEGINS TO
ARRIVE. ONLY A COUPLE OF VERY WEAK DISTURBANCES IN THE ATMOSPHERE
MAY PROMOTE SOME COASTAL DRIZZLE OTHERWISE LITTLE TO NO RAIN
IS ANTICIPATED. THE DRY AND WARM WEEK WILL BRING AFTERNOON HIGH
TEMPERATURES UP 10 TO 15 DEGREES ABOVE NORMAL ACROSS PORTIONS OF
THE INTERIOR, COURTESY OF BUILDING HIGH PRESSURE ALOFT. THE
HOTTEST TEMPERATURES ARE EXPECTED ON TUESDAY, THURSDAY, AND NEXT
WEEKEND. AN ONSHORE COMPONENT TO LOW- LEVEL WINDS SHOULD KEEP THE
IMMEDIATE COAST CLOSER TO NORMAL. HOWEVER, THERE ARE INDICATIONS
THAT FLOW WILL BECOME MORE OFFSHORE BY NEXT WEEKEND, PARTICULARLY
N OF CAPE MENDOCINO. AS A RESULT, HIGH TEMPERATURES ARE EXPECTED
TO RISE ABOVE 70 AT THE COAST.

&&

.AVIATION...OVERNIGHT, CONDITIONS IN KCEC AND KACV DROPPED DOWN TO
MVFR. DO EXPECT MVFR/IFR CONDITIONS TO LINGER THROUGH THE FIRST PART
OF THE MORNING FOR THESE LOCATIONS DUE TO LOW CLOUDS AND AREAS OF
DRIZZLE. CONDITIONS SHOULD IMPROVE DURING THE DAY FOR BOTH KCEC AND
KACV, AND THEY SHOULD IMPROVE TO VFR. FOR TONIGHT, DO EXPECT
CONDITIONS TO LOWER BACK TO MVFR OR LOWER AS LOW CLOUDS RETURN TO
THE COASTAL TERMINALS.  DO EXPECT VFR TO PREVAIL FOR THE NEXT 24
HOURS FOR KUKI. /RCL

.MARINE...AN ACTIVE WEEK FOR THE MARINE WEATHER DEPARTMENT IN NW
CALIFORNIA. THE LIGHT TO MODERATE SOUTHERLY WINDS ON SUNDAY WILL
BE COMING TO AN END. HIGH PRESSURE WILL BUILD OVER EAST PACIFIC
OCEAN, AND THIS WILL TIGHTEN THE NORTHERLY PRESSURE GRADIENT OVER
NW CALIFORNIA STARTING TODAY. WINDS WILL SHIFT NORTH THIS MORNING,
THEN INCREASE THIS AFTERNOON. WINDS FOR THE SOUTHERN WATERS WILL
REACH SMALL CRAFT ADVISORY LEVELS BY LATE THIS AFTERNOON. THE
STRONG NORTHERLY WINDS WILL SPREAD INTO NORTHERLY OUTSIDE WATERS
THIS EVENING. WITH THE STRONGER NORTH WINDS, THERE WILL ALSO BE
STEEP WIND WAVES OF AROUND 8 TO 10 FEET THROUGH TUESDAY NIGHT. DUE
TO THE STRONG NORTH WINDS AND STEEP SEAS, THE SMALL CRAFT
ADVISORY IS IN EFFECT THROUGH TUESDAY NIGHT/WEDNESDAY. PLEASE
REFER TO THE MARINE WEATHER MESSAGE FOR MORE DETAILS.

THERE WILL BE A BRIEF BREAK IN THE WINDS AND SEAS WEDNESDAY FOR THE
NORTHERN WATERS, AS A WEAK LOW PASSES TO THE NORTH. HOWEVER, THIS
WILL NOT LAST LONG. DO EXPECT ANOTHER HIGH PRESSURE BUILDS OVER NW
CALIFORNIA WATERS, AND THIS WILL BRING IN ANOTHER ROUND OF HAZARDOUS
MARINE CONDITIONS THURSDAY AND FRIDAY. /RCL
