.
SATELLITE ANALYSIS AND TRENDS...WILL ONLY BRIEFLY TALK ABOUT CURRENT
WEATHER AS IT PALES TO WHAT IS ORGANIZING ACROSS THE WESTERN THRU CENTRAL
AND INTO THE EASTERN PACIFIC AS FAR EAST AS 140W.  UPPER CIRCULATION
CENTER ACTUALLY LOOKS BETTER IN IR AND HELPING COMMA CLOUD BAND INTO
NW OREGON THRU W WA AND LEADING EDGE BEGINNING TO SPILL INTO CASCADES.
DEEP MOISTURE OROGRAPHIC LIFT AND GOOD INSTABILITY RELATIVE TO COLD
AIR HELPING TO PRODUCT LIGHT TO MDT/OCCASIONAL HVY PRECIP W WA INTO
EXT NW OREGON.  POSITION OF THIS LOW WILL PLAY A CRITICAL PART IN NEXT
SYSTEMS MOISTURE AIMED AT PACIFIC NW.  THAT MOISTURE AND PLUME OUT ACROSS
THE PACIFIC STILL ORGANIZING.  ORIGINS OF THE MOISTURE PLUME IN THE W
PACIFIC ARE ACROSS THE SOUTHERN PHILLIPEANS.  FROM THERE THE PW PLUME
OF CONCENTRATION OF HIGHEST MOISTURE EXTENDS TO THE REMAINS OF 26W AT
31N/159E.  FROM THERE IT CURLED EASTWARD TO EMBEDDED TROPICAL REMAINS
OF 25W AT 34N/160W.  AND FROM THERE THE LEADING EDGE OF THE MOISTURE
CATCHING UP TO BOWING OUT FRONTAL PLUME OF MOISTURE AT  38N/138W...WHICH
ACTUALLY ALSO HAS A CONNECTION TO SUBTROPICAL MOISTURE NEAR THE HAWAIIAN
ISLANDS.  AND PW ANOMALIES WITH EACH PART OF MOISTURE PLUME ACROSS THE
PACIFIC ARE BETWEEN 160 AND 210 PERCENT OF NORMAL.  SO THERE IS LOTS
OF MOISTURE AND MORE IMPORTANTLY SUB AND TROPICAL MOISTURE AVAILABLE
FOR THE NEXT SERIES OF STORMS TO AFFECT THE PACIFIC NW STARTING LATER
ON SUNDAY AND CONTINUING THRU MONDAY.  AND LOW ALONG NW COAST NOW COULD
FURTHER HELP FOCUS THE MOISTURE AND POINT MASSIVE AMOUNTS OF RAIN AT THE
PACIFIC NW FOR THE END OF WEEKEND INTO THE FIRST PART OF THE WORK WEEK.
WILL CONTINUE TO MONITOR...
