SATELLITE ANALYSIS AND TRENDS...RECENT WATER VAPOR IMAGERY DEPICTS A
WEAK UPPER LVL TROUGH TRACKING SLOWLY E WITH EMBEDDED VORT POSITIONED 20N
162W. IGNACIO NOW WELL NNW OF HAWAII HAS HELPED DRAW ANOMALOUS MOISTURE
OVER THE ISLANDS WITH PWS REACHING UP TO 2.2" ACCORDING TO THE BLENDED
TPW COMPOSITE. WEAK MID-UPPER LVL HEIGHT FALLS IN COMBINATION WITH
ANOMALOUS MOISTURE OVER THE ISLANDS CREATED AN ENVIRONMENT CONDUCIVE FOR
HEAVY RAIN.  LATEST IR IMAGERY SHOWS MOSTLY DISORGANIZED BUT COOLING CLOUD
TOPS OVERSPREADING THE CENTRAL ISLANDS WITH MAIN BAND OF CONVECTION SEEN
EXTENDING S OF LANAI.  TRACKING THE CU FIELD IN VIS IMAGERY INDICATES
LOW LVL ESE FLOW OVER THE BIG ISLAND AND CENTRAL ISLANDS WHICH LINES
UP WITH ASCAT WINDS OF THE 0004 METOP-B PASS WHILE WINDS RECORDED ON
THE WESTERN ISLANDS ARE SOUTHERLY ACCORDING TO SURFACE OBS. THIS WEAKLY
CONFLUENT LOW LVL AXIS THROUGH THE CENTRAL ISLANDS ALONG WITH UPPER LVL
DIFFLUENT WINDS ACCORDING TO SATELLITE DERIVED WINDS HAS HELPED ORGANIZE
A BAND OF CONVECTION THAT IS CONTINUING TO BE FED MOISTURE FROM THE SE
AND SLOWLY TRACKING E.  NOT PARTICULARLY CONFIDENT THAT THE MAIN BAND OF
CONVECTION WILL MAKE IT TO THE WESTERN COAST OF THE BIG ISLAND DUE TO THE
FACT THAT THE LOW LVL INFLOW WILL EVENTUALLY BE IMPEDED BY TOPOGRAPHY
ON THE BIG ISLAND.   GIVEN THE MOISTURE IN PLACE AND SOUTHEASTERLY
SURFACE WINDS OF 15 KNOTS ACCORDING TO  THE LATEST METOP-B PASS EXPECT
AT LEAST A LOCALIZED HEAVY RAIN THREAT FOR THE BIG ISLAND.  DUE TO THE
DISORGANIZED NATURE OF THE CONVECTION OVER THE CENTRAL ISLANDS EXPECT
A LOCALIZED HEAVY RAIN THREAT AS WELL.

AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
