SATELLITE ANALYSIS AND TRENDS...LATEST G11 IMAGERY SHOWS FNTL CLOUD BAND
IS APPROACHING SW OR AND N COAST OF CA. AMSU IMAGERY FROM 1058Z SHOWED
PRECIP EXTENDING FM EITHER SIDE OF 130W FM S OF 50N TO 37N THEN SWWD
TO 33N 139W. AMSU AND RECENT G11 HAVE SHOWN NEG TILT OFF WA AND NW OR
COAST..WITH STEADY EWD PUSH TWD SW OR AND N COAST OF CA AS WELL AS TWD
SFO BAY REGION. RAIN RATES RANGED UP TO 0.2-0.25"/HR..BUT MUCH OF THE
PRECIP COVERAGE AREA HAD RATES OF 0.1"/HR OR LESS ACCORDING TO THE 1058Z
AMSU PASS. SINCE THAT TIME..G11 IR IMAGERY HAS SHOWN CLOUD TOP COOLING
W OF THE N COAST.. INDICATING THAT OVERALL RATES ARE LIKELY INCRG IN
COVERAGE. AS FOR PW'S...THE INDICATED RANGE WAS BTWN 0.9-1.2".
BASED ON LATEST TRENDS..LOOKS LIKE CORE IMPACT THIS MORNING/EARLY AFTN
WILL TARGET WFO EKA CWA.
.
AS FOR NEXT SYSTEM UP STREAM..LATEST G11 WV AND IR IMAGERY
SHOWS DEVELOPMENT TAKING SHAPE BTWN 140W-150W WITH A NW-SE
CONFIGURATION. COMBINATION OF IR AND WV ANIMATIONS SUGGESTS TWO PSBL
VORTS..AROUND 45N 146W AND AND 46N 150W. VERY IMPRESSIVE JET..WITH APPX
180KT CORE.. EXTENDS FM WPAC TO S OF DEVELOPING SYSTEM..THEN DIGGING INTO
BASE OF TROP APPCHG CA. IN ADDITION TO STRONG UPPR DYNAMICS..THIS DVLPNG
SYSTEM ALSO CONTAINS SUBTROPICAL MOISTURE PER PW PLUME IN AMSU IMAGERY.
1240Z PASS INDICATED LEADING EDGE OF RAINFALL EXTENDING FM 42N 142W TO
49N 151W..WITH RATES RANGING UP TO 0.2-0.3"/HR. COMPARING TO PREVIOUS AMSU
PASSES..THERE HAS BEEN A GENERAL INCR IN MOD/HVY RAIN RATE COVERAGE. WILL
CONTINUE TO MONITOR PROGRESS OF THIS UPSTREAM SYSTEM AND ISSUE UPDATED
SPENES MESSAGES LATER TODAY AND TONIGHT.
