SATELLITE ANALYSIS AND TRENDS...LATEST POLAR SATELLITE IMAGERY FROM THE
NOAA AMSU USING 89GZ CHANNEL REVEALS SOME INTERESTING FRONTAL FEATURES
ASSOCIATED WITH PRIMARY OCCLUDED LOW CENTERED NEAR 42N/142W AND SMALLER
POLAR LOW INTERACTING WITH PRIMARY LOW TO THE S AND E.  WELL-ESTABLISHED
OCCLUDED FRONT/DEFORMATION ZONE EXTENDS FROM 42N/142W ENE TO 51N/124W
(OVER NRN VANCOUVER ISLAND).  WATER VAPOR LOOP SHOWS THIS FEATURE SLOWLY
SINKING SSE OVER TIME IN RESPONSE TO HEIGHT FALLS OCCURRING OVER THE
ERN GULF OF AK.  THIS TREND IS EXPECTED TO CONTINUE OVER THE NEXT 12 HRS
LIKELY RESULTING IN THIS BOUNDARY NEARING NW WA BTWN 08-12Z AND IN TURN
USHERING IN ADDITIONAL RAINFALL.

FURTHERMORE...A SUBTLE AND ATTM DRY WARM FRONT IS NOTED EXTENDING NE
FROM THE POLAR LOW REACHING AS FAR AS 46N/127W.  IT IS THE INTERACTION
BETWEEN ALL THESE FEATURES THAT MAY LEAD TO AN ENHANCEMENT IN RAINFALL
COVERAGE AND INTENSITY DURING THE OVERNIGHT HRS.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 0000-1200Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...WITH THE PRESENCE OF A WARM FRONT LIFTING NE
ALL THE WHILE A MOIST FRONTAL BOUNDARY...LIKELY EVOLVING INTO A COLD
FRONT...DROPS SE...THESE FEATURES MAY ACT TO ENHANCE MOISTURE/FLOW
CONFLUENCE.  AS MID TO UL ENERGY AND HEIGHT FALLS APPROACH FROM THE N
AND W THIS EVENING ANOTHER ROUND OF MODERATE RAIN SHOWERS SHOULD TEND
TO DEVELOP.  FAVORABLE SRLY FLOW ASSOCIATED WITH WARM FRONT MAY ALSO
ACT TO LOCALLY ENHANCE RAIN RATES ALONG SWRLY SLOPES.  THE TIMING OF
STEADIER ENHANCED RAINS APPEARS TO BE MOSTLY BTWN THE 06-12Z PERIOD.
