.
SATELLITE ANALYSIS AND TRENDS...BIG PICTURE FROM WATER VAPOR SHOWED
UPPER LEVEL PATTERN OF RIDGES AND TROUGHS STRENGTHENING.  TROUGH NEAR THE
DATELINE AND SW OF THE ALEUTIANS WAS PROGRESSIVE AND CONTINUED TO BUILD A
RIDGE OUT AHEAD IN THE W GULF OF ALASKA.  DOWNSTREAM RAMIFICATIONS ALREADY
BE FELT WITH DARK AREA CENTERED 45N/131W SLIDING SE AND ALLOWING TROUGH
TO DEEPEN AND DIG AND 150-175 MAX UPPER LEVEL WINDS ASSOCIATED WITH POLAR
JET WAS AIMING SE TOWARD N CA WITH SOME NOSING INTO THE SFO BAY AREA.
SOME DIFFLUENCE NOTED ALONG AND JUST OFF THE S OREGON/N CA COAST WHICH
WILL ADD TO DYNAMICS AS SYSTEM WORKS SOUTHWARD TOWARD BURN AREAS LATER
TONIGHT AND SUNDAY.  LOOP OF MICROWAVE PW MOISTURE SHOWED MODERATE
CENTERED 43N/146W TO 37N/133W WITH MAX VALUE OF 1.35" NEAR 40N/140W.
PW MOISTURE ALIGNED PROPERLY/
NORMALLY ABOUT 4-6 DEGREES SOUTH OF AXIS OF POLAR JET. AND WITH AIMING
SEWD JET AND PW PLUME AND SHARPENING/DEEPENING OF TROUGH...GOT TO BELIEVE
STEADY MODERATE PRECIP OFFSHORE AND INLAND N CA THRU OREGON WILL STAY
TOGETHER...EVEN INCREASE WHILE WORKING CONTINUING TO WORK SOUTH TOWARD
THE BURN AREAS OF CENTRAL AND SOUTHERN CA LATER THRU TONIGHT AND SUNDAY
MORNING (SEE NCEP HPC EXCESSIVE RAINFALL DISCUSSION).  THOUGH RAIN RATES
FROM SSMI...F-16 SSMIS AND NOAA AMSU GENERALLY UNDER 0.10"/HR OFFSHORE N
CA ON LATEST MICROWAVE PASSES.  BELIEVE THESE RATES WILL INCREASE WITH
DEEPENING TROUGH AND DIGGING JET FOR GREATER DYNAMICS AND ADDITION OF
ANY OROGRAPHICS AS PRECIP MOVES INLAND CENTRAL THIS EVENING AND S CA
LATER TONIGHT AND SUNDAY MORNING.
WILL CONTINUE TO MONITOR...
