.
SATELLITE ANALYSIS AND TRENDS...MICROWAVE IMAGERY SHOWING 1.0"+ PW PLUME
EXTENDING INTO THE WRN PACIFIC APPROACHING 135W AT 0630Z.  PW VALUES
LOOKING TO EFFECT THE PAC NW SHOULD REMAIN NEAR 1.0"...HOWEVER AMSU
0635Z PASS SHOWED SOME AREAL AVERAGE RAIN RATES UPWARDS OF .25/HR  NEAR
47N/145W...HOWEVER THINKING THAT THESE RATES ARE EXAGGERATED SINCE THE
CONVECTION WAS NEAR THE EDGE OF THE SATELLITE SWATH.  IR IMAGERY ALSO
HELPS THIS THINKING AS TOPS STILL REMAIN WARMER WITH COLDEST CONVECTIVE
TOPS STILL NEAR 45N/135W.  WV/GOES SATELLITE WINDS SHOWING 140KT JET
WILL HELP TO KEEP THE MOISTURE CONNECTED FOR AT LEAST THE NEXT DAY OR
SO WHICH CAN BE SEEN ON AMSU PW IMAGERY AS AN AREA OF 1.25"+ PW NEAR
40W/150W.  WHILE IT IS STILL YET TO BE SEEN EXACTLY HOW THIS WILL PLAY
OUT...THINKING THE LEADING EDGE OF MOISTURE WILL HELP TO ENHANCE THE
SHOWERS CURRENTLY ALONG THE PAC NW COAST AND COULD PRODUCE MODERATE
RAINS AT TIMES LATER THIS AFTERNOON AND EVENING..ESPECIALLY FOR THE
HIGHER TERRAIN MAINLY IN WA/OR.  CURRENTLY THINKING TREND WILL CONTINUE
AND WILL SEE PRECIP GRADUALLY SINK SOUTH INTO NRN CA AFTERWARDS AS THE
ENHANCED AREA MENTIONED ABOVE MOVES CLOSER TO THE COAST...BUT AM NOT
GOING TO MAKE ANY GUESSES AS TO THE TIMING.
