AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
945 AM PDT THU JUN 3 2010

.SYNOPSIS...ANOTHER STRONG LOW PRESSURE SYSTEM WILL PRODUCE
ADDITIONAL RAIN THIS AFTERNOON THROUGH FRIDAY. DRIER WEATHER IS
EXPECTED ON SATURDAY.

&&

.UPDATE...QUICK UPDATE TO MOVE UP ONSET TIMING OF RAIN.
DISTANCE/TIME INTERPOLATION ON LEADING EDGE OF RAIN ON RADAR
SUGGESTS THAT RAIN WILL BEGIN WITHIN THE NEXT HOUR ALONG THE REDWOOD
COAST. ALSO INCREASED POPS A BIT FOR THIS AFTERNOON. HENRY

&&

.DISCUSSION /ISSUED 315 AM PDT/...RAIN HAS LET UP SIGNIFICANTLY
OVERNIGHT AND HAVE REDUCED POPS FOR THIS MORNING. EARLY MORNING
OBSERVATIONS HAVE BEEN REPORTING PERIODS OF LIGHT RAIN/HEAVY DRIZZLE
WITH LITTLE TO NO ACCUMULATIONS. WARM AIR AND MOISTURE ADVECTION
AHEAD OF THE NEXT WARM FRONT WILL CONTINUE WARM AND MUGGY CONDITIONS
TODAY AND TONIGHT.

STRATIFORM LIGHT RAIN WILL RETURN TO NW CA LATE THIS AFTERNOON AS A
WARM FRONT ASSOCIATED WITH ANOTHER STRONG PACIFIC STORM APPROACHES
THE COAST. SREF FORECASTS THE SURFACE LOW 3 TO 4 STANDARD DEVIATIONS
DEEPER THAN NORMAL. THE HEAVIEST RAINFALL WILL OCCUR WITH THE
TRAILING COLD FRONT AROUND MIDNIGHT TONIGHT. THE NORTHWARD POSITION
OF A 140+ KT UPPER LEVEL JET WILL AGAIN FOCUS THE HIGHER RAINFALL
TOTALS ACROSS NORTHERN PORTIONS...ALTHOUGH SOUTHERN REGIONS WILL SEE
MORE RAINFALL WITH THIS EVENT THAN THE FORMER. SUBSTANTIAL TROPICAL
MOISTURE IS AVAILABLE WITH OFFSHORE PRECIPITABLE WATER APPROACHING 2
INCHES. GUSTY SOUTH WINDS WILL DEVELOP LATE TONIGHT AHEAD OF THE
COLD FRONT AND CONTINUE WITH THE FRONTAL PASSAGE. THESE WINDS WILL
AFFECT THE SPATIAL DISTRIBUTION OF THE RAIN WITH LEEWARD AREAS
RECEIVING LESS RAIN THAN AREAS NOT BLOCKED BY TERRAIN. THINK THE
DYNAMICS AND MOISTURE WITH THIS STORM WILL OUTWEIGH THE RAIN SHADOW
EFFECTS...AND NORTHERN PORTIONS WILL SEE ANOTHER ROUND OF RECORD
BREAKING RAIN. THE RAIN WILL PERSIST THROUGH FRI MORNING WITH
ISOLATED TO SCATTERED SHOWERS BY FRI AFTERNOON. RIVERS AND AREA
STREAMS WILL RISE RAPIDLY AND LOCALIZED FLOODING CAN BE EXPECTED ON
SOME OF THE ROADWAYS.

CONFIDENCE IS GREATER THAT THERE WILL BE A BREAK IN RAIN FRIDAY
NIGHT AND SATURDAY. AN UPPER LEVEL SHORTWAVE WILL BRING A CHANCE OF
RAIN SATURDAY NIGHT. WITH SHOWERS POSSIBLY LINGERING INTO SUNDAY
MORNING. THE FORECAST FOR NEXT WEEK IS UNCERTAIN AS THE GFS
FORECASTS A RIDGE AND DRY WEATHER AND THE ECMWF CONTINUES A
PROGRESSIVE WETTER PATTERN. HAVE LEANED TOWARDS CLIMO POPS IN THE
EXTENDED DUE TO THE UNCERTAINTY. TH

.AVIATION...SHALLOW MOIST ONSHORE FLOW HAS BEEN CREATING IFR CIGS AND
VSBYS IN LIGHT RAIN AND MISTY DRIZZLE...MAINLY AT THE COAST. A
DEVELOPING LOW PRESSURE SYSTEM OFFSHORE WILL DISRUPT THE ONSHORE WINDS
AND BRING LIGHT SOUTHERLIES BY AFTERNOON. THIS SHOULD BUST UP THE BULK
OF THE SHALLOW MOISTURE AS MID LAYER CLOUDS INCREASE. SOUTH WINDS WILL
INCREASE FURTHER TONIGHT...WHICH SHOULD LIFT UP CEILINGS EVEN MORE. THE
NAM12'S AND GFS'S MODEL OUTPUT STATISTICAL GUIDANCE LOOKED TOO LOW WITH
THE CIGS AND VSBYS TONIGHT GIVEN THE MIXING FROM THE SOUTH WINDS...SO
HAVE IGNORED IT.

&&

.MARINE...DEVELOPING STORM OVER THE NE PACIFIC WILL BRING GALE FORCE
SOUTH WINDS AND HAZARDOUS SEAS TO THE WATERS TONIGHT. WARNINGS HAVE
BEEN ISSUED FOR PZZ470 AND PZZ450 FOR BRIEF DURATION GUSTS TO 35-40 KT.
SEAS HAVE BEEN GRADUALLY SUBSIDING OVERNIGHT...BUT CDIP BUOY 244 WAS
STILL 8 FT AT 9 SECONDS AS OF 1 AM PDT. SEAS WILL SUBSIDE TODAY...BUT
SPIKE UP AGAIN TONIGHT IN RESPONSE TO THE STRONG SOUTH WINDS ASSOCIATED
WITH A WARM FRONT. A WARNING FOR SEAS HAS BEEN HOISTED MAINLY FOR 10 FT
SHORT PERIOD WIND-DRIVEN WAVES. STEEP WEST SWELL WILL BUILD ON
FRIDAY...REACHING 10 TO 12 FT BY MID AFTERNOON. ENP CONTINUES TO BE THE
MODEL OF CHOICE HERE...AND WILL DEPART FROM SWAN OUTPUT AND INCREASE
SWELL HEIGHTS ONCE AGAIN. WINDS AND SEAS WILL DECREASE SAT NIGHT->SAT.
A WEAKER STORM WILL APPROACH SAT NIGHT INTO EARLY SUN MORNING...AND MAY
GENERATE 15-25 KT IN THE OUTER WATERS. GFS HAS BEEN SHOWING THIS FOR
THE LAST COUPLE OF DAYS...SO SEE NO GOOD REASON TO CONTINUE WITH THE
OLD FORECAST OF NORTH WINDS. WINDS WILL EVENTUALLY GO NORTH AFTER
TROUGH PASSAGE ON SUN.
