AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
336 AM PDT WED APR 21 2010

.SYNOPSIS...SCATTERED RAIN SHOWERS AND HIGH ELEVATION SNOW SHOWERS
WILL CONTINUE TODAY. WINDS WILL REMAIN STRONG AND GUSTY. DRIER
AND MILDER WEATHER IS EXPECTED THURSDAY THROUGH THE WEEKEND.

&&

.DISCUSSION...EARLY MORNING SURFACE ANALYSIS SHOWS THE COLD FRONT
THAT IMPACTED THE AREA ON MONDAY AND TUESDAY ENTERING THE GREAT
BASIN. LOW PRESSURE IS CLOSING OFF OVER SOUTH-CENTRAL
CALIF...WHILE HIGH PRESSURE IS BUILDING ACROSS THE EASTERN
PACIFIC. THE DEEP CYCLONIC CIRCULATION ASSOCIATED WITH THE CLOSED
LOW IS WORKING TO BRING SOME MID AND LOW LEVEL MOISTURE BACK INTO
OUR CWA. WHILE PRECIPITATION HAS BEEN ON THE DECREASE...SCATTERED
SHOWERS WILL CONTINUE THROUGH THE DAY WITH REMNANT
INSTABILITY...MOISTURE AND COLD AIR ALOFT. THERE MAY BE A BRIEF
INCREASE IN SHOWER ACTIVITY DURING THE MID TO LATE
AFTERNOON...BUT OVERALL WE EXPECT A GRADUAL DECREASE IN
PRECIPITATION COVERAGE AND INTENSITY. SNOW LEVELS ARE CURRENTLY
NEAR 3000 FEET AND WILL RISE ONLY SLIGHTLY THROUGH THE DAY. SINCE
ONLY SMALL AMOUNTS OF PRECIPITATION ARE EXPECTED...WE EXPECT
LITTLE TO NO SNOW ACCUMULATION.

WIND WILL BE THE MAIN CONCERN TODAY...CAUSED LARGELY BY THE
TIGHTENING PRESSURE GRADIENT. WINDS SPEEDS EARLY THIS MORNING
HAVE BEEN CONSISTENTLY GUSTING UP TO 30 MPH. WHILE WINDS MAY
TEMPORARILY DIMINISH FOR A FEW HOURS AROUND DAYBREAK...THEY WILL
ONCE AGAIN INCREASE THROUGH THE DAY AND PEAK FROM THE MID
AFTERNOON TO EARLY EVENING. IT IS QUITE LIKELY THAT SOME AREAS
WILL GUSTS IN EXCESS OF 40 TO 45 MPH...BUT THIS WILL MAINLY BE
ALONG THE IMMEDIATE COAST AND ON EXPOSED RIDGETOPS. WE OPTED NOT
TO ISSUE A WIND ADVISORY AS WINDS WILL LARGELY REMAIN BELOW
CRITERIA ACROSS THE MAJORITY OF THE AREA.

SHOWER ACTIVITY WILL COME TO AN END TONIGHT WITH HIGH PRESSURE
DRAWING CLOSER TO THE COAST. NORTHERLY WINDS WILL REMAIN BRISK
THROUGH THE NIGHT AND INTO THURSDAY. A THERMAL TROUGH WILL
DEVELOP OVER INTERIOR CALIFORNIA BY THURSDAY AFTERNOON...WITH AN
OFFSHORE FLOW FOR MUCH OF THE REGION. DRY WEATHER IS EXPECTED
THURSDAY THROUGH THE WEEKEND...ALTHOUGH A WEAK DISTURBANCE MAY
BRING A FEW SHOWERS NEAR THE OR/CA BORDER ON SATURDAY. THE NEXT
LONGWAVE TROUGH WILL APPROACH ON MONDAY...WITH ANOTHER CHANCE OF
RAIN LATE MONDAY INTO TUESDAY. BETTWY

&&

.AVIATION...12Z WEDNESDAY THROUGH 12Z THURSDAY...RADAR SHOWS
ISOLATED SHOWERS MOVING ACROSS NORTHWEST CALIFORNIA. THESE
SHOWERS WILL DIMINISH DURING THE MORNING HOURS. THE MAIN IMPACT
CONTINUES TO BE GUSTY NORTH WINDS RESULTING FROM A STRONG
PRESSURE GRADIENT. GUSTS APPROACHING 35 KT ARE POSSIBLE ALONG THE
IMMEDIATE COAST AND EVEN HIGHER OVER THE COASTAL RIDGES THIS
AFTERNOON. VFR WILL PREVAIL. STROZ

&&

.MARINE...THE FORECAST REMAINS ON TRACK AND DID NOT MAKE ANY MAJOR
CHANGES. GALE FORCE WINDS AND HAZARDOUS SEAS WILL CONTINUE AS THE
EASTERN PACIFIC HIGH INTERACTS WITH LOW PRESSURE INLAND. THE
WORST CONDITIONS ARE STILL FORECAST TO BE OVER THE OUTER WATERS
WHERE GUSTS COULD APPROACH 45 KT AND WIND WAVES WILL RANGE FROM
14 TO 16 FT, ESPECIALLY ACROSS THE SOUTHERN OUTER WATERS. COMBINE
THE WIND WAVES WITH A BACKGROUND WEST SWELL NEAR 10 FT AND
SIGNIFICANT WAVE HEIGHTS MAY APPROACH 20 FT IN SOME SPOTS. THE
GRADIENT WILL EASE LATE THURSDAY, ALLOWING WINDS AND SEAS TO COME
DOWN THURSDAY NIGHT INTO FRIDAY. STROZ

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.

NORTHWEST CALIFORNIA COASTAL WATERS...GALE WARNING UNTIL 3 AM PDT
     FRIDAY PZZ450-455-470-475.
