AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
433 AM PDT WED APR 15 2009

.SYNOPSIS...A RIDGE OF HIGH PRESSURE CURRENTLY BUILDING OVER THE
WEST COAST WILL BRING DRY WEATHER TO NORTHWEST CALIFORNIA TODAY THROUGH
THE WEEKEND.

&&

.DISCUSSION....SATELLITE IMAGERY SHOWS THE UPPER LEVEL LOW
SPINNING OVER NEVADA AND GRADUALLY MOVING TO THE SOUTHEAST. THE
REMAINING COLD TEMPERATURES ASSOCIATED WITH THIS LOW ARE CURRENTLY
OVER INTERIOR SECTIONS. ONCE AGAIN TEMPERATURES ALONG THE REDWOOD
COAST ARE RUNNING WELL ABOVE WHAT WAS FORECAST DUE TO BREEZY WINDS
LASTING LONGER THAN EXPECTED. DUE TO THIS HAVE DECIDED TO DROP THE
FROST ADVISORY FOR THE REDWOOD COAST. WINDS HAVE DECREASED SO
WOULD NOT BE SURPRISED TO SEE TEMPERATURES IN THE WIND SHELTERED
AREAS DROP TOWARDS THE MID 30S BY SUNRISE UNDER THE MOSTLY CLEAR
SKIES. BUT IT DOES NOT LOOK LIKE IT WILL BE OVER A LARE ENOUGH
AREA LONG ENOUGH TO KEEP THE ADVISORY GOING. ALSO NEED TO REMEMBER
THAT SUNRISE IS APPROACHING 630 AM SO THE SHORTER NIGHTS MAKE IT
HARDER FOR IT TO GET REAL COLD. THE FREEZE WARNINGS REMAIN UP FOR
THE NORTH COAST INTERIOR AND THE MENDOCINO INTERIOR BECAUSE
TEMPERATURES ARE EASILY AT OR BELOW FREEZING FOR THEM RIGHT NOW.

FROST ADVISORIES MAY BE NEEDED TONIGHT FOR THE INLAND
ZONES...MAINLY THE MENDOCINO INTERIOR...BUT HAVE HELD OFF ON
ISSUING THEM AT THIS TIME BECAUSE TEMPERATURES ARE MARGINAL AND
WANT THE DAY CREW TO TAKE A CLOSER LOOK AT THINGS TO MAKE SURE WE
ARE SPOT ON.

AN UPPER LEVEL RIDGE WILL BEGIN TO BUILD OVER THE WEST COAST TODAY
AND IT WILL REMAIN IN PLACE THROUGH EARLY NEXT WEEK. A WEAK FRONT
WILL MOVE THROUGH THURSDAY NIGHT INTO FRIDAY MORNING...BRINGING
CLOUDS AND THE SLIGHT CHANCE OF LIGHT RAIN TO LOCATIONS NORTH OF
CAPE MENDOCINO. OTHERWISE...THE RIDGE WILL CONTINUE TO DOMINATE OUR
WEATHER THROUGH THE WEEKEND. EXPECT DRY WEATHER AND SLIGHTLY ABOVE
NORMAL TEMPERATURES OVER THE WEEKEND. STROZ

&&

.AVIATION...PREDOMINATELY VFR CONDITIONS CAN BE ANTICIPATED OVER
MOST OF NORTHWEST CALIFORNIA THROUGH THE NEXT TAF CYCLE. THE STRONG
NORTHERLY WINDS EXPERIENCED ALONG THE COAST THE LAST COUPLE DAYS WILL
DIMINISH TODAY WITH ONLY SOME GUSTS NEAR 20 KT EXPECTED IN THE
AFTERNOON. SOME LOW CLOUDS AND FOG MAY BRING BRIEF PERIODS OF MVFR
CONDITIONS TO KACV LATE IN THE DAY.  INTERIOR SITES SHOULD ALSO SEE
VFR CONDITIONS WHILE KUKI ALSO OBSERVES A DROP IN THE NORTHERLY
WINDS TODAY.

&&

.MARINE...NORTHERLY WINDS WILL BE A BIT MORE SUBDUED TODAY BUT STILL
REMAINING WITHIN SCA CRITERIA OVER ALL OF THE COASTAL WATERS WITH
PEAK GUSTS OCCURRING IN THE AFTERNOON AGAIN TODAY. A WEAK FRONT WILL
ENTER THE NORTHERN WATERS ON THU...WITH BACKING WINDS NORTH OF THE
CAPE...WHILE REMAINING BELOW ADVISORY CRITERIA. AFTER FROPA...WINDS
LOOK TO REMAIN LIGHT UNTIL SATURDAY AFTERNOON WHEN POSSIBLE ADVISORY
CONDITIONS ARE POSSIBLE AS A THERMAL TROUGH SETS UP OVER INTERIOR
CA. A WESTERLY SWELL ASSOCIATED WITH THE FRONT WILL ENTER THE WATERS
ON THURSDAY PEAKING AROUND 7 FT THURSDAY EVENING. A LARGER NW SWELL
WILL ENTER THE WATERS ON SATURDAY.
