SATELLITE ANALYSIS AND TRENDS...CURRENT SAT ANIMATION SHOWS SYSTEM
WINDING UP NICELY NEAR 43N 132.5W WHICH IS IN GOOD AGREEMENT WITH LATEST
18Z GFS RUN.  ANOTHER VORT MAX/JET STREAK CAN BE SEEN NEAR 36N 139.5W
AGAIN IN FAIRLY GOOD AGREEMENT WITH LATEST GFS.  THE LATEST AMSU RR RATES
ARE GENERALLY IN THE .1-.15"/HR BUT THERE IS A HINT OF SOME .25"/HR OR
POSSIBLY A BIT HIGHER.  PW PLUME HAS ORIGINS IN WPAC BUT IT'S NOT A TRUE
SUBTROPICAL CONNECTION. BUT STILL THE PW VALUES NEAR 149W ARE AROUND 1.5".

EXTRAPOLATION PLACES NORTHERN LOW NEAR 42N 126W (WEST OF OR/CA BORDER)
AT 12Z  PERHAPS A BIT FASTER THAN GFS. SOUTHERN JET MAX/VORT EXTRAPOLATES
TO 37N 130W WHICH IS IN AGREEMENT WITH GFS.
