EVENT...BEST PRECIP INTO THE CASCADES WA AND OREGON...HVYST STILL OFFSHORE
N CA...BUT GETTING READY TO MOVE IN THERE...
.
SATELLITE ANALYSIS AND TRENDS...UPPER LOW LIFTING NE AND NOW NEAR
46N/134W...TROUGH TRAILING TO THE WEST AND JET SLIDING EAST TO NW WA COAST
TO OFFSHORE OREGON.  AND MICROWAVE PASSES THIS MORNING CONFIRMING HIGHEST
RATES ALREADY WELL EAST OF THE WA AND MOST OF OREGON COASTS.  BACK EDGE OF
PW MOISTURE PLUME ACTUALLY ALIGNS WELL WITH JET AND SIGNIFICANT LOWERING
PW VALUES WILL OCCUR W WA AND EVENTUALLY NW AND W CENTRAL OREGON THRU
THIS EVENING.  EVEN THOUGH PEAK SUBTROPICAL MOISTURE WELL EAST OF THE
COAST THESE PLACES...INSTABILITY DESPITE LOWER PW VALUES WILL CONTINUE
LIGHT SHOWER PRECIP COAST AND MODERATE TO OCCASSIONAL HVY MOUNTAIN
AND OROGRAPHIC AREAS.  GOOD THING THE BULK OF THE PLUME WAS MOVING AS
TREMENDOUS MOISTURE TRANSPORT AND CONNECTION TO SUBTROPICS AND EMBEDDED
REMAINS OF WEST PAC STORM 25W STILL HAS HELPED PRODUCE SUBSTANTIAL PRECIP
AND WILL CONTINUE A BIT LONGER IN CASCADES...ESPECIALLY OREGON CASCADES
THIS AFTERNOON AND EVENING.
FURTHER SOUTH...MICROWAVE WAS SHOWING HIGHER RAIN RATES (GENERAL 0.1"
TO 0.25"/HR RATE WITH MAX RATES TO 0.4" AMSU AND 0.2"-0.35"/HR WITH MAX
TO 0.5"/HR SSMI) STILL OFFSHORE AND NEAR OREGON COAST AT 1440Z AND SLOWLY
MOVING INLAND AND WITH 700MB/850MB MOISTURE TRANSPORT STILL VERY GOOD ON
50-60KT INFLOW...HVY PRECIP A GOOD BET AT LEAST INTO NW CA AND SPILLING
OVER INTO SW OREGON THRU THIS EVENING UNTIL MAIN PART OF MOISTURE PLUME
WORKS TO THE COAST AND INLAND.
JUST FOR YOUR INFO FROM LONGER PW LOOP...FEATURE AT 32N/178W IS A BLOB
OF MOISTURE FROM THE REMAINS OF WEST PAC STORM 26W THAT GOT LEFT BEHIND
AS 25W PULLED AWAY A FEW DAYS AGO.  WILL BE INTERESTING TO SEE WHERE
IT GOES AND WHETHER IT CAN SURVIVE THE COLD ADVECTION LEFT BY CURRENT
SYSTEM AND UPPER LEVEL FEATURE AT 43N/163W.    WILL CONTINUE TO MONITOR...
