SATELLITE ANALYSIS AND TRENDS...STUBBORN FNTL BOUNDARY/PW MOISTURE PLUME
THAT HAS BROUGHT PERSISTENT RAIN TO OR COAST PAST SEVERAL DAYS IS FINALLY
GETTING NUDGED DOWN THE COAST DUE TO DEEPENING UPR SYSTEM OFF THE BC
COAST AND PROGRESSIVE LARGER SYSTEM NR 165W.
.
HEAVIEST RAIN THIS EVENING HAS BEEN ALG THE LEADING EDGE OF CLD BAND IN
VERY WARM CLD TOP/WARM RAIN PROCESS ENVIRONMENT WITH LIGHTER RAINFALL
ASCD WITH COLDEST ENHANCED CLDS CENTRAL AND NRN OR COAST. MICROWAVE
IMAGERY DEPICTS SWRD SHIFT OF MOISTURE PLUME/HIGHEST RAIN RATES WELL. PW
VALUES HAVE ACTUALLY DIMINISHED SOMEWHAT WITH 04Z AMSU PASS GIVING MAX
VALUES OF ARND 1" IN A NARROW PLUME INTO EXTRM NRN CA. RAIN RATES ALSO
NOT TERRIBLY IMPRESSIVE WITH OVER WATER AREAL AVERAGED RATES MAINLY
.10"/HR OR LESS WITH ISLD .15"/HR. HOWEVER..WITH NAM SHOWING 30-45 KT
WINDS IN 700-800 MB LAYER OROGRAHIC LIFT ABLE TO DOUBLE THESE RATES IN
PREFERRED AREAS ALG THE CST.
.
THEREFORE..HEAVY RAIN THREAT FOR COASTAL SW OR APRS TO BE OVER AND HAS
SHIFTED INTO DEL NORTE AND HUMBOLDT COUNTIES. BUT WITH PROGRESSIVE NATURE
OF SYSTEM NOT EXPECTING ANY PROBLEMS IN NRN CA THROUGH THE NIGHT.
