SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 12/04/12 1525Z SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404 LATEST DATA USED: GOES-15 1500Z HANNA . LOCATION...CALIFORNIA...OREGON...WASHINGTON... . ATTN WFOS...PDT...REV...MFR...STO...MTR...SEW...PQR...EKA... ATTN RFCS...NWRFC...CNRFC... . EVENT...ADDITIONAL HEAVY PRECIPITATION . SATELLITE ANALYSIS AND TRENDS...LATEST WATER VAPOR IMAGERY SHOWS THAT ANOMALOUS UPPER LOW CONTINUES TO BE NEARLY STATIONARY OVER THE GULF OF ALASKA THIS MORNING. A RATHER WELL DEFINED VORTICITY CENTER WAS DROPPING INTO THE BASE OF THE LARGER SCALE TROF AND SHOULD EJECT NE LATER THIS AFTERNOON TOWARDS PORTIONS OF BC AND WASHINGTON. TO THE SOUTH OF THIS, SHEARING OUT POSITIVELY TILTED SHORT WAVE TROF WAS APPROACHING NEAR 130W. CLOUD TOP TEMPERATURES HAVE BEEN COOLING OVER THE LAST FEW HOURS AHEAD OF THIS FEATURE AND HEAVIER PRECIPITATION SHOULD BEGIN TO MOVE ONTO THE COAST OVER THE NEXT FEW HOURS. . LATEST BLENDED PW ANALYSIS INDICATES THAT DEEPER MOISTURE HAS SHIFTED TOWARDS THE SOUTH WITH THE DEEPEST MOISTURE NOW DIRECTED TOWARDS SW OR/NW CA. THE NEXT SURGE OF MOISTURE WAS ASSOCIATED WITH APPROACHING SHORTWAVE TROF NEAR 130W. MAXIMUM PW VALUES WITHIN THIS SURGE WERE RUNNING BETWEEN 1.30-1.60". LATEST NOAA AMSU RAINFALL RATES ASSOCIATED WITH THE DEVELOPING FRONTAL WAVE INDICATED A SMALL AREA OF RAINFALL RATES CENTERED NEAR 35N/135 WHICH RANGED BETWEEN 0.10-0.30'/HR. . SHORT TERM OUTLOOK VALID 1515-2115Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...UPSTREAM FRONTAL WAVE SHOULD CONTINUE TO APPROACH AREA THROUGH THE MORNING AND AFTERNOON HOURS AND THIS SHOULD ALLOW FOR HEAVIER PRECIPITATION TO SPREAD BACK INTO REGION. IT APPEARS AS THOUGH BEST MOISTURE FLUX SHOULD BE DIRECTED INTO PORTIONS OF SW OR AND NW CA. EXPECT LOCALIZED PRECIPITATION TOTALS THROUGH THIS PERIOD TO RANGE BETWEEN 1.0-2.0" IN FAVORED TERRAIN IN SW OR/NW CA. . ....NESDIS IS A MEMBER OF 12 PLANET.... .
