.
SATELLITE ANALYSIS AND TRENDS...BIG PICTURE SHOWED MAIN DEEP UPPER LOW
SPINNING VERY SLOWLY EAST AT 38N/152W.  YESTERDAY'S LOW/TROUGH STRUNG OUT
W TO E AS IT HAS LIFTED NORTH INTO SE GULF OF ALASKA/BRITISH COLUMBIA.
THOSE TWO ANCHORED FEATURED WILL TRY TO STEER SHORTER WAVE SYSTEMS AND
ORGANIZING MOISTURE PLUMES INTO AREA FROM FAR N CA THRU
W WA NEXT 24-36HRS.
FIRST STRONG VORT SCOOTING THRU OLYMPIC PENINSULA AND HELPING TO INCREASE
DEEP MOISTURE INTO PACIFIC NW.  THIS HAS ALLOWED LEADING EDGE OF ALREADY
WELL DEFINED PW PLUME TO BEGINNING REACHING INTO W WA AND
NW OREGON...HAVING ORIGINS WELL W/SW OF THE HAWAIIAN ISLANDS.  RAIN RATES
ALREADY HAVE MOVED INLAND AND HAD REACHED BETWEEN 0.2" AND 0.4"/HR
AREAL AVERAGE ON MICROWAVE EARLIER PASSES.  THESE TYPES OF AMOUNTS CAN
BE EXPECT IN OROGRAPHIC AREAS OF N AND C CASCADES THIS AFTERNOON.
SECOND SYSTEM ON TAIL END OF FIRST NOW HAS PASSED 130W BETWEEN 45N
AND 36N AND AND WILL FURTHER ENHANCE PRECIP INTO W OREGON AND NW CA
THIS AFTERNOON AND EVENING AND FURTHER ESTABLISHED PW MOISTURE PLUME
OUTLINED ABOVE.  BY THE WAY THE PW MOISTURE OF 1.4" IS AS FAR EAST
AND NORTH AS 40N/131W WITH LATEST SSMI/AMSU PASSES.  EMBEDDED IN THIS
SECOND FEATURE ON BOTH SSMI AND AMSU OFFSHORE FAR NW CA AND W OREGON
WERE MAX AREAL AVG INSTANTANEOUS RAIN RATES BETWEEN 0.25" AND 0.50"/HR.
THAT AREA HAS MOVED INLAND WITH A BIT MORE OF THOSE TYPES OF RATES COMING
IN ON TAIL WESTERN END THRU THE AFTERNOON.
THIRD SYSTEM JUST EAST OF 139W AT 40 TO 35N HAS SUBTROPICAL CONNECTIONS
AND MERGED SUBTROPICAL MOISTURE FROM THE WESTERN PACIFIC AND EAST
OF HAWAII MINOR PW MOISTURE PLUMES.  MAX RAIN RATES IN THE 0.50" TO
0.75"/HR RATE.  THIS SHOULD FEED ON EXISTING MOISTURE BEING ESTABLISHED
BY SYSTEMS 1 AND 2 TO BRING EVEN HIGHER AMOUNTS OF PRECIP LATER SUNDAY
NIGHT AND THRU MON.
LAST FEATURE NUMBER 4 IS FRONTAL BOUNDARY APPORACHING 140W AND THAT
WILL BOTH FEED ON FIRST THREE FEATURES AND POSSIBLY BEGIN TO END THE
SIGNIFICANT HVY PRECIP...HARD TO PIN TIME FRAME FOR THAT JUST YET.
WILL CONTINUE TO MONITOR...
