SATELLITE ANALYSIS AND TRENDS...NOAA AMSU PASS FM 0532Z SHOWED 2-3 DEGREE
WD RAIN BAND EXTENDING FM 40N 140W THRU 50N 133W WITH RAIN RATES GENERALLY
LESS THAN 0.1"/HR. 0.1-0.2"HR PIXELS WERE OBSERVED NR/N OF 49N. PW'S
WITH THIS BAND RANGED FM 0.9" TO 1.1..WITH CONSIDERABLY LOWER PW'S E
AND W OF THE BAND. ANIMATION OF PW AND RR LOOPS SHOWED THAT PW'S HAD
REMAINED THE SAME WHILE RAIN RATES HAD DECRD COMPARED TO EARLIER PASSES.
.
LATEST GOES IR IMAGERY..COMBINED WITH EARLIER AMSU RAIN RATES
PASS.. INDICATES THAT LEADING EDGE OF RAIN BTWN 44-50N HAD REACHED AS
FAR E AS  129/130W. HIGHER CLOUDS HAVE SHEARED FURTHER E TO COAST AND
ARE OUTRUNNING THE RAIN.
.
VIGOROUS SHORT WAVE IS MOVE STEADILY E ALONG 140W..WITH VORT CENTER
INVOF 47N 140W. GOES STLT WIND ANALYSIS SHOWS JET STREAKS S OF VORT
AND ACRS VANCOUVER/NW WASHINGTON. LL GOES STLT WIND INDICATE 85H WINDS
AROUND 50KTS W OF FRONTAL BAND. THUS..THE COMBINATION OF STRONG UPPR
DYNAMICS AND LL WINDS SUGGEST THAT AS PRECIP MOVES ACRS THE COAST RAIN
RATES WILL EVENTUALLY BECOME GREATER THAN THOSE INDICATED BY EARLIER
MICROWAVE PASS..ESP OVER WINDWARD UPSLOPE AREAS. WOULD EXPECT SOME MOD
TO HVY RAINFALL RATES/TOTALS LATER TODAY.
