EVENT...HEAVY RAINFALL THREAT OVER THE CENTRAL HAWAIIAN ISLANDS
.
SATELLITE ANALYSIS AND TRENDS...WATER VAPOR IMAGERY CONTINUES TO SHOW A
SUBSTANTIAL PLUME OF MOISTURE OVER THE CENTRAL ISLANDS WITH RELATIVELY
DRIER ML AIR IMPINGING UPON KAUAI. THIS IS IN LINE WITH THE 12Z SOUNDING
AT LIHUE SHOWING 1.57" PW AND CORRELATES WELL WITH THE BLENDED TPW
PRODUCT SHOWING ABOUT 1.5" TO 2.0" OVER THE AREA.  AMSU RAIN RATES
HAVE FALLEN SIGNIFICANTLY OVER THE PAST SEVERAL HOURS WITH PERHAPS
ONLY .25" OVER AND NEAR AND HIGHER RATES CONFINED WELL TO THE N AND
S OF THE ISLANDS. ADDITIONALLY IR IMAGERY SHOWS WARMER CLOUD TOPS AND
LIGHTING DENSITY PRODUCT  INDICATES VIRTUALLY NO DEEP CONVECTION OVER
THE PAST SEVERAL HOURS. FINALLY...LL CONVERGENCE SEEMS TO BE MODEST AT
MOST WITH SFC WINDS GENERALLY SE 10 TO 15 KT AS PER 0724Z SCATTEROMETER
PASS. NEVERTHELESS ANOMALOUS MOISTURE FETCH ALONG WITH REGION LYING
BROADLY WITHIN A   SWATH OF THE FAVORABLE RRQ OF THE UL JET COUPLED
WITH HINTS A S/W MOVING ACROSS THE ISLANDS JUSTIFIES AN ONGOING THREAT
OF HEAVY PRECIPITATION.
.
SHORT TERM OUTLOOK VALID 1530-2000Z...LOW TO MEDIUM CONFIDENCE FACTOR OVER
THE SHORT TERM. GIVEN THE ABOVE TRENDS CONTINUE TO BELIEVE THAT THERE
IS AN ONGOING THREAT OF HEAVY RAIN OVER THE CENTRAL ISLANDS ALBEIT LESS
CERTAIN THAN PREVIOUS MESSAGES. THIS THREAT IS ESPECIALLY ENHANCED IF
PRECIPITATION ORGANIZES SW TO NE  AS A TROUGH MOVES INTO THE AREA AND
INTERACTS WITH FAVORED UPSLOPE REGIONS.
