SATELLITE ANALYSIS AND TRENDS...CIRCULATION CENTER OF VIGOROUS MID LEVEL
LOW NOW CENTERED NEAR 38N/145W.  LEAD SHORTWAVE TROF HAS BEEN RAPIDLY
LIFTING NE AND WAS WELL DEPICTED IN WATER VAPOR IMAGERY BY DRY SPOT
NEAR 45N/137W.  BEST JET STREAK APPEARS TO HAVE PROPAGATED TO SE SIDE
OF TROF SO TROF SHOULD REMAIN SOMEWHAT PROGRESSIVE BUT A WELL DEFINED
PINEAPPLE CONNECTION SHOULD ALLOW FOR A PROLONGED PERIOD OF INCREDIBLY
STRONG MOIST ONSHORE FLOW.
.
SHORTWAVE RIDGE AXIS MENTIONED IN PREVIOUS SPENES APPEARS AS THOUGH IT HAS
MADE IT'S WAY ONSHORE OVER THE PAST FEW HOURS AND WITH IT'S PASSAGE HAVE
SEEN A CORRESPONDING INCREASE OF RAINFALL OVER MOST OF THE DISCUSSION
AREA.  0447Z NOAA AMSU PASS WAS SHOWING A LARGE AREA OF RAINFALL RATES
OF BETWEEN 0.20-0.30"/HR WITH ISOLATED LOCATIONS OVER 0.50"/HR NORTH
OF 45N AND EAST OF ABOUT 131W.  LOCAL VWPS WERE SHOWING AN INCREDIBLE
LLJ RANGING ANYWHERE BETWEEN 60-80KTS.  THIS COMBINED WITH AN ANOMALOUS
MOISTURE PLUME IN EXCESS OF 200% ABOVE CLIMATOLOGICAL NORMAL VALUES FOR
ABOUT A 1500 MILE DISTANCE FROM 41N/129W TO 25N/150W SHOULD LEAD TO SOME
SPECTACULAR MOISTURE FLUX ANOMALIES OVER THE ENTIRE DISCUSSION AREA FOR
AT LEAST THE NEXT 12HRS.  ON THE SHORT TERM THOUGH, BELIEVE RAINFALL
TOTALS OF 1.0-1.5" ARE QUITE POSSIBLE OVER THE NEXT 3-6HRS WITH LOCALLY
HIGHER TOTALS POSSIBLE IN FAVORED TERRAIN.  WILL CONTINUE TO MONITOR.
