EVENT...DISCUSSION OF CONVECTIVE RAINFALL TRENDS APPROACHING THE CENTRAL
HAWAIIAN ISLANDS.
.
SATELLITE ANALYSIS AND TRENDS...WATER VAPOR IMAGERY CONTINUES TO SHOW
A SUBSTANTIAL SUBTROPICAL FEED OVER THE ISLANDS. ALSO OF RECENT NOTE
IS MORE DEFINITION WITH THE MID-UPPER LEVEL FEATURE LOCATED SW OF THE
ISLANDS W OF 165W. IN RESPONSE TO THIS...SATELLITE IMAGERY IS SHOWING
MORE OF A BAROCLINIC LEAF SIGNATURE CENTER OVER THE CNTRL AND WRN
ISLANDS. ADDITIONALLY THE RIGHT ENTRANCE REGION OF THE UL JET LIES NEARLY
COINCIDENT TO THE MOISTURE PLUME WHICH IS ADDING FURTHER TO THE LARGER
SCALE LIFT. SSMIS FROM LESS THAN TWO HOURS AGO SHOWS RAIN RATES OF JUST
OVER 0.5" PER HOUR WITH CONVECTION TO THE S THRU SSW OF THE CNTRL AND WRN
ISLANDS WHILE PW VALUES WERE STILL RUNNING NEAR 2" CLOSE TO THE ISLANDS.
.
SHORT TERM OUTLOOK VALID 1930-0130Z...MEDIUM CONFIDENCE FACTOR
CONCERN STILL EXISTS FOR LOCALLY HEAVY RAINFALL TO OVERSPREAD PORTIONS
OF THE CNTRL AND WRN ISLANDS GIVEN THE AMOUNT OF UPSTREAM CLOUD
TOP ENHANCEMENT S AND SW OF THE ISLANDS. CONFIDENCE FROM A SYNOPTIC
PERSPECTIVE FOR LOCALLY HEAVIER RAINFALL IS CERTAINLY HIGHER GIVEN
THE FAVORABLE UPPER JET POSITION, THE APPARENT DEVELOPMENT OF A WAVE,
AND THE LOCATION OF THE MOISTURE PLUME THOUGH PRECISELY IDENTIFYING THE
SPECIFIC THREAT AREAS IMPACTED BY HEAVIER EMBEDDED CONVECTION IS MORE
PROBLEMATIC WHICH LOWERS THE OVERALL CONFIDENCE.
