SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 12/21/14 0747Z

LATEST DATA USED: GOES-15  0730Z KUSSELSON

LOCATION...NW CALIFORNIA...W OREGON...W WASHINGTON...

ATTN RFCS...NWRFC...CNRFC...
.
EVENT...MOIST FIRE HOSE IN CONJUNCTION WITH JET CONTINUES ALIGNED FROM
W CENTRAL OR TO SW WA AND INLAND...BUT MOST ANY OROGRAPHIC AREA FROM NW
CA TO S WA CASCADES CONTINUES VULNERABLE TO LOCALLY HVY RAINS...
.
SATELLITE ANALYSIS AND TRENDS...ONLY SUBTLE CHANGES FROM LAST MESSAGE
WITH WELL DEFINED JET AXIS CONTINUING FROM THE PACIFIC INTO THE SW
WA-NW OREGON CORE AREA AND EAST ALONG THE OR-WA BORDER AREA AND SE INTO
SE IDAHO/N UT.  VERY MOIST PLUME OR CONCENTRATION OF HIGHEST MOISTURE
NOW CENTERED 20N/165W TO 40N/149W TO 44N/130W INTO NW AND W CENTRAL
OREGON...BUT REALLY FANNING OUT WITH HIGH MOISTURE SOUTH TO CALIFORNIA
AND NORTH TO SW WA.   GREATEST MOVEMENT OF PLUME SOUTH OF 40N IN THE
PACIFIC WEST AND NW OF HAWAII.  DRY AIR MAKING INROADS TO THE EAST NORTH
OF 50N TO N/C VANCOUVER ISLAND BEHIND WEAK SHORT WAVE MOVING ACROSS S
BC AND THIS HAVING THE EFFECT OF MORE SHOWERY PRECIP NW INTO
W CENTRAL WA AND LIGHT TO MODERATE/OCCASIONAL HVY SHOWERS INTO THE
OLYMPICS.    ALSO NOTICED ON THE AMSU PW LOOP A POSSIBLE BREAK IN THE
PLUME NEAR 142W AND ASSOCIATED WITH SOME DRIER AIR/LOWER PWATS  PUSHING
EAST ACROSS 45N/152W.  WHEN ONE OVERLAYS CURRENT 700MB FORECAST WINDS ON
PRECIP WATER DATA OVER THE PACIFIC...BEST MOISTURE TRANSPORT ALMOST THE
LENGTH OF THE BEST MOISTURE INTO WEST CENTRAL TO SW OREGON...AND LITTLE
WEAKER AS FAR NORTH AS THE WA-OR BORDER AND SOUTH TO NW CA.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 0730-1030Z...MEDIUM TO HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...AGAIN JET ALIGNMENT CO MINGLED WITH HEART OF
TPW MOISTURE PLUME INTO THE CENTRAL OREGON COAST MAKES AREA FROM SW-W
CENTRAL OREGON TO NW OREGON VULNERABLE FOR HIGHEST AMOUNTS, ESPECIALLY
WEST FACING MOUNTAINS.  STILL LOCALLY HVY NORTH THRU SW WA..PORTIONS OF
OLYMPICS, BUT WITH A BIT LESS MOISTURE BUT CONTINUED JET AND LOW LEVEL
OROGRAPHICS...WHILE SOUTH INTO NW CA...VERY HIGH MOISTURE IN COMBO WITH
OROGRAPHICS FOR LOCALLY HVY HIGH SPOTS THERE WITH LIGHT/OCCL MODERATE
LOWER SPOTS OF NW CA.    AGAIN QMORPH MICROWAVE RAIN ACCUMULATIONS FOR
THE 6HR PERIOD ENDING 04Z NOT IMPRESSIVE OFFSHORE WITH UP TO 0.3"...BUT
THAT IS A BIT DECEIVING WITH INLAND TERRAIN AND UPSLOPE PROVIDING A
2-3 TIMES OFFSHORE RATES INLAND AND THAT DOES SHOW UP IN THE PRODUCT
WITH MAX AMOUNTS OF 0.8" PER 3HRS/ISOLATED 1" SW WA TO SW OREGON AND
EVEN SOME GREATER THAN 1" AMOUNTS PER 3HRS FROM THE UPSLOPE AREAS OF
THE SOUTHERN WA CASCADES TO SOUTHERN OREGON CASCADES (CENTRAL OREGON).
