LATEST DATA USED: GOES-11 0330Z  KUSSELSON

ATTN RFCS...NWRFC...CNRFC...
.
EVENT...ANOMALOUS RAIN EVENT FOR WEST COAST OF FAR N CA/W OREGON...
.
SATELLITE ANALYSIS AND TRENDS...OFFSHORE MICROWAVE RAIN TREND FROM 1732Z
TO 0127Z ABOUT THE SAME WITH RAIN RATES SOUTH OF 40N GENERALLY UNDER
0.05"/HR AND NORTH OF 40N BETWEEN 0.05"/HR AND 0.15"/HR WITH GREATEST
PUSH TO 1-2 DEGREE WIDE RAIN BAND TOWARD THE NORTHERN CA/
SW TO W CENTRAL OREGON COAST.  THIS INITIAL RAIN BAND THAT AT 0127Z
WAS CENTERED AT 129W AT 40N/128.5W NOW AND A LITTLE FURTHER EAST NEAR
128W AT 41N...SO MOTION IS TAKING ACTIVE PART OF THE FRONT A LITTLE MORE
TOWARD FAR NORTHERN CA COAST AND SW AND W CENTRAL OREGON.  LEADING EDGE
OF PW PLUME FROM AMSU AND SSMI WERE NEAR 1.5" AND THAT IS ACTUALLY A
LITTLE HIGHER THAN 12HRS AGO AND THAT AND THE COMPUTER MODELS HOLD THIS
TOGETHER AND WEAKEN IT A BIT...BUT STILL ARE CLAIMING THIS IS ABOUT 3 TO
4 STANDARD DEVIATIONS ABOVE NORMAL...AND LATEST BLENDED TPW ANOMALY LOOP
FROM CIRA/COLOSTATE AT:  HTTP://AMSU.CIRA.COLOSTATE.EDU/GPSTPW SHOWING
MOISTURE OFFSHORE WITH THIS FRONTAL BAND GETTING CLOSE TO 200 PERCENT
OF NORMAL.  ONE OF THE NEGATIVES TO SIGNIFICANT RAIN GETTING PAST THE
COASTAL MOUNTAINS IS WIND FLOW AND SOUTHERLY FLOW WOULD ACTUALLY BE
BETTER FOR FAR N CA AREAS THAN SW TO W CENTRAL OREGON...SO
THAT COULD KEEP THE RAIN RATES FROM BEING HIGHER WHEN THE SYSTEM MOVES
INLAND ON TUESDAY.  BUT BIG PICTURE A POSITIVE FOR SOME OF THE WET
WEATHER OFFSHORE MAKING IT INLAND AS RIDGE AT 160-165W STILL BUILDING...
120KT WIND SPD MAX FROM SATELLITE AT 45N/147W AND SO TROUGH AT 135W
COULD CONCEIVABLE DEEPEN A BIT DESPITE LATEST WATER VAPOR LOOP SHOWING
VORT AT 42N/133W TRYING LIFT NORTH OF EAST RECENTLY.
SO WILL CONTINUE TO MONITOR...WILL SEND OUT A GRAPHIC ON OUR WEB PAGE
SHORTLY.
