SATELLITE ANALYSIS AND TRENDS...LATEST WATER VAPOR IMAGERY DEPICTS POTENT
UPPER LEVEL LOW INVOF 42.93N 130.5O W WITH HIGHLY DIFFLUENT UPPER LEVEL
PATTERN EVIDENT ACROSS DISCUSSION REGION. ADDITIONALLY THE OPERATIONAL
SATELLITE WINDS DOES SHOW A 100-110 KNOT JET STREAK ACROSS NW CA/SW OR
THAT HAS HELPED INCREASE UPPER LEVEL DIVERGENCE THAT SHOULD CONTINUE TO
AID LIFT NEXT SEVERAL HOURS. MOISTURE PLUME CONTINUES TO HAVE A TROPICAL
CONNECTION TO T.C. KILO WITH CORE OF PLUME AS HIGH AS 1.6-1.8" AS IT WRAPS
UP INTO PAC NW.  THIS MOISTURE PLUME CORRESPONDS TO 175-200% OF NORMAL PER
ANOMALIES. IR IMAGERY HAS ALSO SHOWN INCREASING ENHANCEMENT/BAROCLINIC
LEAF/COMMA SIGNATURE AHEAD OF FRONTAL BAND AND WOULD ANTICIPATE AN
INCREASE IN RAIN COVERAGE NEXT FEW HOURS. A 0431Z AMSU PASS SUGGESTED
AN AREAL AVG INSTANTANEOUS RAINFALL RATE OF .2-4"/HR IN DEFORMATION AXIS
AND WOULD ANTICIPATE SIMILAR IF NOT HEAVIER RATES POSSIBLE AS 40 KNOT SW
85H FLOW HELPS ADVECT PACIFIC MOISTURE INTO REGION AND INTERACTS WITH
OROGRAPHICS. ADDITIONALLY QMORPH SUGGEST TOTALS OFFSHORE IN THE 1-2"
RANGE WITH ISOLATED 2-2.5" ENDING AT 5Z. EXPECT MOD TO HVY RAINFALL WITH
RATES .25-.5"/HR+ POSSIBLE IN BEST BANDS FOR MUCH OF W WA.
.
A GRAPHIC SHOWING  QMORPH ESTIMATE WILL BE AVAILABLE ON THE INTERNET
ADDRESS LISTED BELOW IN APPROXIMATELY 10-15 MINUTES.
