AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
358 AM PDT SUN MAY 3 2009

.SYNOPSIS...A SERIES OF STORMS WILL MAINTAIN WET WEATHER ACROSS
NORTHWEST CALIFORNIA INTO THE MIDDLE OF NEXT WEEK.
&&

.DISCUSSION...THE WET WEATHER PATTERN WILL CONTINUE FOR THE NEXT
SEVERAL DAYS AS A SERIES OF UPPER LEVEL DISTURBANCES ROTATE AROUND
THE PARENT LOW OFF THE BC COAST. RAIN WILL CONTINUE THROUGH MID
MORNING BEFORE TAPERING OFF THROUGH THE EVENING AS ONE MINOR SHORT
WAVE EXITS THE REGION. ANOTHER...STRONGER SHORT WAVE WILL MOVE
ACROSS THE REGION LATE MON. MODELS COMING INTO BETTER AGREEMENT IN
DEVELOPING A SFC LOW WELL OFFSHORE MON. WINDS WILL INCREASE OVER THE
WATERS AND ALONG THE COAST N OF CAPE MENDOCINO MON AFTERNOON IN
RESPONSE TO THE TIGHTENING PRESSURE GRADIENT. THE STRENGTHENING SFC
LOW WILL COMBINE WITH DIFFLUENT FLOW ALOFT...PWATS AROUND 1.25
INCHES AND WAA TO GENERATE DECENT RAINS ACROSS NW CA MON INTO TUE.
THIS SYSTEM WILL DROP BETWEEN 1 TO 2 INCHES OF RAIN ACROSS NW CA BY
TUE MORNING WITH TERRAIN FAVORED LOCATIONS RECEIVING UP TO 4 INCHES.
ANOTHER SHOT OF RAIN EXPECTED WED AS ANOTHER SHORT WAVE MOVES ACROSS
THE REGION. RIVER LEVELS ACROSS THE REGION WILL CONTINUE TO RISE
THROUGH WEDNESDAY. BY THURSDAY...THE UPPER TROUGH WILL FINALLY PUSH
INLAND BRINGING A DRYING AND WARMING TREND HEADING INTO NEXT
WEEKEND. MODEL SOLUTIONS SHOW A WEAK TROUGH DEVELOPING OVER THE PAC
NW SAT RESULTING IN SCHC POPS MAINLY ALONG THE ORCA BORDER. BC
&&

.MARINE...ALTHOUGH A FEW ADVISORY LEVEL GUSTS ARE NOTED NEAR PT
ARENA EARLY THIS MORNING...WINDS AND SEAS IN GENERAL WILL SLOWLY
DIMINISH DURING THE DAY. THE RESPITE WILL BE SHORT LIVED...AS DEEP
LOW PRESSURE PASSES TO THE NORTHWEST OF THE WATERS MONDAY AFTERNOON
AND EVENING. THE PREFERRED SOLUTIONS REMAIN THE GFS/EURO DUO WHICH
ARE WELL CORROBORATED BY THE HPC SURFACE FEATURES OVER THE NEXT
COUPLE OF DAYS. MARINE MOS GUIDANCE SHOWS WINDS OF 30-40 KT
DEVELOPING OVER THE NORTHERN WATERS TOMORROW AFTERNOON/EVENING AND
THE STRENGTH OF THE GRADIENT LOOKS TO SUPPORT SUCH SPEEDS. SO WE
HOISTED A GALE WARNING AND HAZARDOUS SEAS WARNING FOR THIS PERIOD.
THE LATTER WARNING MAY BE A LITTLE IFFY GIVEN THE RELATIVELY SHORT
DURATION OF WINDS BUT BUILDING FRESH SWELL IN TANDEM WITH WIND WAVE
SHOULD BE SUFFICIENT FOR COMBINED SEAS VERIFICATION. BURGER
&&

.AVIATION...STRATUS CEILINGS RANGE BETWEEN MVFR AND VFR AT EARLY
MORNING WITH INTERMITTENT SHOWERS. THESE SHOWERS WILL DIMINISH IN
COVERAGE DURING THE AFTERNOON...BUT WEAK WINDS WITH POOR MIXING WILL
LIKELY KEEP FLIGHT CONDITIONS HOVERING BETWEEN MVFR AND VFR AT THE
COAST WITH SOME IMPROVEMENT TO VFR FOR INLAND AREAS. BURGER
