AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
334 PM PDT MON MAR 28 2016

.SYNOPSIS...THE UPPER LEVEL TROUGH NOW MOVING EAST CONTINUES TO
BRING GUSTY NORTH WINDS TO THE AREA. EXPECT THESE WINDS TO
CONTINUE TONIGHT EXCEPT IN SHELTERED AREAS. AFTER A CHILLY NIGHT
TONIGHT HIGH PRESSURE BUILDS INTO THE AREA BRINGING WARMING
TEMPERATURES AND DRY CONDITIONS THROUGH THE REST OF THE WEEK.

&&

SHORT TERM (THROUGH THURSDAY)...THE UPPER LEVEL TROUGH OVER THE
AREA IS BEGINNING TO MOVE TO THE EAST THIS AFTERNOON. THE NORTH
WINDS BEHIND THE PASSING SYSTEM HAVE INCREASED AS FORECAST WITH
GALES DEVELOPING OVER THE COASTAL WATERS AND GUSTY WINDS TO THE
LOW 30 MPH RANGE. GUSTS TO NEAR 40 MPH ARE POSSIBLE IN THE
EXPOSED AREAS ALONG THE COAST EARLY THIS EVENING AND OVER THE
COASTAL HILLS. WINDS OVER THE INLAND VALLEYS WILL LIKELY LET UP
AS SHELTERED VALLEYS DECOUPLE LATER THIS EVENING. INLAND RIDGES
WILL LIKELY SEE WINDS CONTINUE THROUGH THE NIGHT. ONCE THE WINDS
OVER THE LOWER LEVELS OF THE INLAND VALLEYS GO CALM TEMPERATURES
WILL RAPIDLY PLUMMET TO THE MID 30S. HAVE CONTINUED A FROST ADV
FOR TONIGHT OVER INLAND PORTIONS OF MENDOCINO COUNTY. UKIAH MAY
NOT SEE FROST...BUT CONFIDENCE IS HIGHER THAT OTHER AREAS SUCH AS
POTTER VALLEY AND THE ANDERSON VALLEY WILL SEE FROST. THE REDWOOD
COAST MAY SEE SOME FROST OVER LIMITED SHELTERED LOCATIONS BUT AS
WINDS WILL LIKELY STAY UP AT THE COAST HAVE OPTED TO NOT ISSUE AN
ADV. THIS SHOULD BE MONITORED AND IF WINDS WERE TO DROP OFF
EARLIER OVER NIGHT AN ADV MAY BE NEEDED.

TUESDAY HIGH PRESSURE BUILDS INTO THE PACIFIC NORTHWEST AND THE
TROUGH CONTINUES TO MOVE EAST AND SOUTH. THIS LOOKS TO BRING
MOSTLY CLEAR SKIES AND ANOTHER COOL NIGHT TUESDAY NIGHT INTO
WEDNESDAY MORNING. TONIGHT WILL LIKELY BE THE COLDEST...LOW TEMPERATURES
WEDNESDAY MORNING WILL LIKELY BE ONLY A FEW DEGREES WARMER IN THE
UPPER 30S.

WEDNESDAY AND THURSDAY HIGH PRESSURE BUILDS INTO THE AREA. WINDS
WILL DIMINISH EACH DAY AND TEMPERATURES WILL WARM. MOS GUIDANCE IS
INDICATING THAT WEDNESDAY WILL BE THE WARMEST DAY WITH
TEMPERATURES IN THE MID 60S AT THE COAST AND NEAR 70 IN THE
INLAND AREAS. MKN

.LONG TERM (FRIDAY THRU SUNDAY)....THE 5-WAVE MODEL CONTINUES TO
SHOW UPPER RIDGING OVER THE WESTERN UNITED STATES THROUGH THE
EXTENDED FORECAST. GENERALLY, THIS WILL KEEP WARMER TEMPERATURES AND
MOSTLY DRY WEATHER FOR THE LATE WEEK. MODELS SHOW INDICATIONS OF A
SHORTWAVE OVERTOPPING  THE RIDGE OVER AND BRING A CHANCE FOR LIGHT
RAIN OVER THE WEEKEND. THE FIRST SHOT OF LIGHT RAIN COULD BE
SATURDAY MORNING BUT MODELS HAVE TRENDING SLOWER AS THE SYSTEM WILL
WEAKEN AS IT APPROACHES THE WELL ESTABLISHED RIDGE. THIS WILL LIKELY
BE THE CASE THROUGH THE WEEKEND AND WILL NOT REALLY SEE A SIGN OF
RAIN UNTIL EARLY NEXT WEEK IF THE RIDGE DOES IN FACT BREAK DOWN. AS
OF NOW, I AM SIDING WITH THE SLOWER AND DRIER GFS BUT KEPT POPS
SLIGHTLY BELOW CLIMO. CHANCES ARE GOOD THAT THIS UPCOMING WEEKEND
WILL BE MOSTLY DRY. STAY TUNED. KML

&&

.AVIATION...SKIES BECAME BASICALLY CLEAR TO WIDELY SCATTERED TODAY
FOLLOWING AN UPPER LEVEL TROUGH THAT BROUGHT SHOWERS TO THE
REGION. FOR THE REMAINDER OF THE PERIOD...VFR CONDITIONS EXPECTED
OVER THE REGION. A STRONG GRADIENT OVER THE AREA WILL ALLOW ROBUST
NORTH-NORTHWEST WINDS TO PERSIST THROUGH AT LEAST EARLY
EVENING...MOST NOTABLY AT THE COASTAL AIRFIELDS/AIRPORTS. TA

&&

.MARINE...NORTHERLY GALES WILL PERSIST THROUGH THE AFTERNOON AS
BUILDING HIGH PRESSURE CAUSES THE PRESSURE GRADIENT TO FLEX. THE
STRONGER WINDS WILL BE FARTHER OFFSHORE BUT EXPECT GALE FORCE GUSTS
TO IMPACT THE INNER WATERS AS WELL, ESPECIALLY AROUND CAPE
MENDOCINO. THE SMALL CRAFT ADVISORIES WILL LIKELY BE NEEDED
FOLLOWING THE GALES LATE TONIGHT AND EARLY TUESDAY MORNING. LARGE
STEEP WAVES WILL BUILD IN RESPONSE TO THE INCREASING WINDS. THE WIND
DRIVEN WAVES WILL SETTLE THROUGH THE MIDDLE OF THE COMING WEEK AS
HIGH PRESSURE WEAKENS. ENP SIGNALS FOR A SWELL TO PROPAGATE THE
WATERS TOWARDS THURSDAY AND MAX OUT ON FRIDAY AT  5 FT AROUND 16
SECONDS. FORTUNATELY, THIS WON'T CAUSE THE SEA STATE TO BUILD TO
MASSIVE HEIGHTS BUT COULD POSSIBLY POSE A THREAT TO BEACH GOERS AND
DIVERS. IT WILL BE SOMETHING TO KEEP AN EYE ON. WINDS AND SEAS
SHOULD SETTLE FURTHER OVER THE WEEKEND. KML
