AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
311 PM PDT SAT APR 30 2016

.SYNOPSIS...DRY AND WARMER WEATHER CONDITIONS ARE EXPECTED THROUGH
THE WEEKEND AS HIGH PRESSURE REBUILDS OVER THE REGION. COOLER AND
UNSETTLED WEATHER CONDITIONS WITH A CHANCE OF SHOWERS WILL RETURN
BY THE MIDDLE OF THE COMING WEEK.

&&

.DISCUSSION...COASTAL AREAS WILL REMAIN SUNNY THROUGH THE
REMAINDER OF THE AFTERNOON BUT THE GUSTY NORTHERLIES WILL
PERSIST AS THE SURFACE PRESSURE GRADIENT REMAINS A BIT TIGHT
JUST OFF THE COAST. AN UPPER RIDGE OF HIGH PRESSURE WILL SHARPEN
OVER THE EXTREME E PACIFIC OVER THE NEXT DAY OR SO...AS A
RESULT...TEMPERATURES WILL BEGIN TO WARM ACROSS THE REGION TODAY
THROUGH SUNDAY AS FLOW BECOMES A LITTLE MORE OFFSHORE TONIGHT AND
SUNDAY. THE POTENTIAL FOR MAX TEMPERATURES TO RISE INTO THE UPPER
60S TO MID 70S INCREASES FOR SUNDAY AND MONDAY WHILE INLAND
TEMPERATURES WILL RISE INTO THE LOWER 80S ON SUNDAY...WITH A FEW
LOCATIONS REACHING THE MID 80S. ALTHOUGH OFFSHORE FLOW WILL
COMMENCE TONIGHT SOME SOUTHERLY STRATUS MAY SNEAK INTO THE COASTAL
AREAS SUNDAY NIGHT INTO MONDAY...BUT THIS SHOULD BE FAIRLY
LOCALIZED AND BRIEF WITH A FAIR AMOUNT OF SUNSHINE STILL EXPECTED
DURING THE DAY TIME HOURS. THE UPPER RIDGE WILL SHIFT E EARLY
NEXT WEEK AS A LOW PRESSURE TROF DIGS OVER THE E PACIFIC. AN OMEGA
BLOCK PATTERN WILL DEVELOP OVER THE ROCKIES. THIS WILL BRING
TEMPERATURES BACK DOWN TO MORE SEASONAL LEVELS BY MID-WEEK. ENOUGH
MOISTURE AND INSTABILITY WILL BE IN PLACE TO BRING CHANCES FOR
SHOWERS ACROSS MAINLY INLAND PORTIONS OF THE AREA. HAVE CONTINUED
TO INCLUDE ISOLATED THUNDERSTORMS OVER THE INTERIOR AS WELL. A FEW
STORMS MAY DEVELOP TUESDAY AFTERNOON OVER THE EXTREME NE PORTION
OF THE AREA WITH ANY STORMS MOVING NE-E OUT OF THE AREA. CAPE
AREAS ARE VERY NARROW DURING THIS PERIOD. SLIGHTLY BETTER CHANCES
FOR STORMS ARE EXPECTED ON WEDNESDAY AFTERNOON WITH DEEPER
AVAILABLE CAPE. A FEW THUNDERSTORMS ARE AGAIN POSSIBLE ON THURSDAY
AFTERNOON...AND SLOW NE-SW STORM MOTION MAY ALLOW FOR A STRAY
STORM TO DRIFT BACK TOWARD THE COAST BEFORE WEAKENING. INSTABILITY
WILL DECREASE LATE IN THE WEEK...WITH DECREASING RAIN CHANCES AND
NO THUNDERSTORMS ANTICIPATED. JT/SEC

&&

.AVIATION...WIDESPREAD VFR CONDITIONS WILL CONTINUE ALTHOUGH AT
LEAST ANOTHER 6 TO 12 HOURS OF GUSTY NORTHERLIES CAN BE EXPECTED
ALONG THE COAST. THE NEXT COUPLE OF NIGHTS MAY SEE SOME BRIEF AND
LOCALIZED AREAS OF LOW CLOUDS AND FOG BUT TOWARD MID WEEK SOME
LIGHT OFFSHORE FLOW SHOULD BRING BACK A 2 DAY WINDOW OF VFR.

&&

.MARINE...STRONG HIGH PRESSURE WILL MAINTAIN GALES OFFSHORE AND
LARGE, STEEP WAVES TONIGHT. WINDS WILL BEGIN TO DECREASE EARLY
SUNDAY MORNING AS THE RIDGE OF HIGH PRESSURE OFFSHORE BREAKS DOWN
AND ALLOWS THE PRESSURE GRADIENT ACROSS THE COASTAL WATERS TO RELAX.
STEEP WAVES WILL GRADUALLY SUBSIDE IN RESPONSE TO THE DECREASING
WINDS ON SUNDAY. WE WILL NEED TO CONSIDER ISSUING A SMALL CRAFT
ADVISORY AND/OR HAZARDOUS SEAS WARNING AFTER THE GALES EXPIRE EARLY
SUNDAY MORNING. BY EARLY NEXT WEEK WINDS WILL BECOME LIGHT AND
SOUTHERLY WHILE THE SEA STATE WILL BE DOMINATED BY A MIDDLE PERIOD
NW SWELL. HIGH PRESSURE WILL BUILD TOWARDS THE WEST COAST LATE NEXT
WEEK WHICH WILL CAUSE FRESH NORTH WINDS TO DEVELOP ONCE AGAIN. KML

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...
     SMALL CRAFT ADVISORY UNTIL 11 PM PDT THIS EVENING FOR PZZ450-455.

     GALE WARNING UNTIL 3 AM PDT SUNDAY FOR PZZ470-475.
