EVENT...HEAVIER PRECIPITATION SHOULD BEGIN ARRIVING BETWEEN 18-21Z
.
SATELLITE ANALYSIS AND TRENDS...LEAD IMPULSE THAT PROVIDED THE OVERNIGHT
RAIN TO THE DISCUSSION AREA HAS LIFTED INTO NE OR AND PRECIPITATION HAS
BECOME MUCH MORE SCATTERED IN IT'S WAKE.  TRAILING VORITICTY LOBE STILL
HELPING TO FORCE AREAS OF LIGHT TO OCCASIONALLY MODERATE RAINFALL OVER
HUMBOLDT AND MENDOCINO COUNTIES AND ALSO OVER THE NORTHERN BAY AREA.
IN OTHER AREAS, MOIST SOUTHWESTERLY FLOW WILL CONTINUE TO HELP FOCUS
OROGRAPHICALLY ENHANCED PRECIPITATION ON FAVORED  S/SW FACING TERRAIN
FOR THE NEXT FEW HOURS.
.
WATER VAPOR IMAGERY SHOWS THAT VIGOROUS AND FAST MOVING SHORTWAVE TROF IS
RAPIDLY APPROACHING THE AREA.  MID LEVEL DRYING HAS NOT MADE MUCH PROGRESS
SOUTH OF ABOUT 36N SO BELIEVE DIGGING TO FEATURE HAS JUST ABOUT CEASED,
ALTHOUGH HAVE NOTED STRENGTHENING MOISTURE GRADIENT JUST UPSTREAM WHICH
COULD POSSIBLY AID IN SOME SLIGHT ADDITIONAL DIGGING.  REGARDLESS THOUGH,
CLOUD PATTERN HAS BEEN RAPIDLY COOLING AND EVOLVING  INTO AN IMPRESSIVE
BAROCLINIC LEAF PATTERN.  1132Z NOAA AMSU RAIN RATE ALGORITHM WAS SHOWING
AN AREA OF 0.3-0.5"/HR RAINFALL RATES NEAR THE TAIL END OF LEAF PATTERN.
SATELLITE DERIVED UA DIVERGENCE PRODUCT INDICATES THAT BEST UL DIVERGENCE
NOW CROSSING 126W AND THIS FORCING SHOULD BEGIN TO APPROACH COAST BY
ABOUT 18Z.  WOULD EXPECT RAINFALL TO GRADUALLY INCREASE AFTER 18Z WITH
HEAVIEST RAINFALL LIKELY BETWEEN 20Z-02Z OVER THE COASTAL RANGES AND
THEN GRADUALLY TRANSITIONING INLAND AFTER THAT TIME FRAME.
