.
SATELLITE ANALYSIS AND TRENDS...UPPER LOW CONTINUES TO PROGRESS E/NEWRD
TOWARD THE WEST COAST AND WAS CENTERED NEAR 37N/133W PER WV ANALYSIS. ONE
BAND HAS ALREADY PUSHED ASHORE INTO NORTH/CENTRAL CA AND HAS PRODUCED
LIGHT RAIN OVER THIS AREA FOR THE PAST FEW HOURS.  HYDROESTIMATOR 1 HR
AMOUNTS FROM 19Z HAVE AN AREA OF .4-.5" OF RAINFALL  OVER LAKE, NAPA AND
MEDOCINO COUNTIES..HOWEVER LOCALLY HEAVIER AMOUNTS SHOULD BE EXPECTED. IN
THE WAKE OF THE FIRST BAND..A MORE IMPRESSIVE (MAIN) BAND IS EXPECTED TO
MOVE OVER THE WESTERN PARTS OF THE DISCUSSION AREA IN THE NEXT 1-2 HRS.
AMSU AREAL AVERAGED RAIN RATES FROM THE LATEST 1516Z PASS ARE SEEN TO
BE AS HIGH AS .45"/HR..WHICH IS SLIGHTLY LOWER THAN RATES OBSERVED ABOUT
3 HRS AGO.
.
AMSU AND GOES DERIVED PW'S RANGE BETWEEN 1.0-1.3" WITHIN AN AREA CENTERED
AT 30N/130W.  THE COASTAL SYSTEM CONTINUES TO TAP INTO THIS MOISTURE
AND WITH A 120KT JET PER GOES WINDS IT IS EXPECTED THAT RAINFALL RATES
WILL INCREASE AS MAIN BAND MOVES ONSHORE OVER THE NEXT FEW HOURS WITHIN
INCREASED UVVS FROM JET EXIT REGION DYNAMICS AND CONTINUED ISENTROPIC
ASCENT IN THE SAME VICINITY.
