LATEST DATA USED: GOES-11 2015Z KUSSELSON
NOAA AMSU: 1334Z/1515Z DMSP SSMI: 1355Z/1427Z/1609Z

LOCATION...CENTRAL AND SOUTHERN CALIFORNIA...

ATTN WFOS...SGX...HNX...LOX...STO...MTR...
ATTN RFCS...CNRFC...
.
EVENT...QUICK HARD SHOT OF PRECIP WITH FRONTAL MOISTURE PLUME...BUT MAY
BE ENOUGH FOR ISOLATED PROBLEMS...
.
SATELLITE ANALYSIS AND TRENDS...FRONTAL MOISTURE PLUME MOVING PRETTY
QUICKLY AND BEST MOISTURE TRANSPORT OF 700MB WINDS BLOWING PARALLEL
THE FRONTAL MOISTURE PLUME SHORT FOR MODERATE EFFICIENCY OVER A SHORT
PERIOD OF TIME...BUT OVER THAT SHORT PERIOD OF TIME GENERAL RAIN RATES AS
PER MICROWAVE IMAGERY COULD BE 0.1"-0.2"/HR LOW LANDS AND 0.2"-0.4"/HR
HIGHER SPOTS WITH ISOLATED 0.5"-0.6"/HR RATES OVER A COUPLE OF HRS THAT
MAY RESULT IN ISOLATED PROBLEMS ESPECIALLY THE CLOSER TO BURN AREAS.
BACK EDGE OF PRECIP CLOSELY CORRESPONDING TO BACK EDGE OF CLOUDS NORTHERN
TO CENTRAL CA COAST AND JUST INLAND...SO THOSE AREAS OUT OF THE WOODS.
ON FRONT END...LEADING EDGE OF ENHANCED CLOUDS CENTRAL TO S CA COASTAL
AREAS WILL LEAD TO INCREASED RAINFALL RATES WITH DECREASING RATES NORTH
PART IN CENTRAL CA COASTAL AREAS LATER THIS AFTERNOON AND EVENING AND
INCREASING RAINFALL SANTA BARBARA COUNTY AND SOUTH THRU THIS EVENING.
DRY AIR ALONG AND OFF FAR S CA COAST WILL TEND TO WEAKEN OR SHRINK FRONTAL
MOISTURE PLUME BUT ALSO FOR A TIME TEND TO CONCENTRATE HIGHEST MOISTURE
IN A MORE FOCUSED AREA FOR BREIF HEIGHTENED RAINFALL THAT COULD BRIEFLY
CAUSE PROBLEMS.  JET FROM GOES WATER VAPOR WINDS STILL MUCH STRONGER ON
WEST SIDE OF INCOMING TROF AND COULD ALLOW FOR SOME SLOWING AND DEEPENING
OF TROUGH...BUT THIS IS STILL A QUICK MOVING SYSTEM AND DON'T EXPECT
LONG TERM HVY RAINS TO RESULT IN LONG TERM PROBLEMS.
WILL CONTINUE TO MONITOR...
