HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0030 UTC TUE DEC 06 2016

BASED ON DATA THROUGH 0000 UTC DECEMBER 06 2016

A DEEP TROUGH AT THE SURFACE AND ALOFT DOMINATES OVER THE CENTRAL
PORTION OF THE AREA...INCLUDING THE MAIN HAWAIIAN ISLANDS. A
SHORTWAVE UPPER LEVEL TROUGH AXIS CURRENTLY LOCATED OVER THE
CENTRAL PORTION OF THE STATE CONTINUED TO LIFT NORTHEASTWARD AT
25 TO 30 MPH...WHILE A BROADER LONGWAVE UPPER LEVEL TROUGH COVERS
THE AREA FROM THE ISLANDS TO JUST WEST OF THE DATELINE.

THE SHORTWAVE UPPER TROUGH IS GENERATING A 400 TO 500 MILE WIDE
SHIELD OF BROKEN TO OVERCAST LAYERED CLOUDS WITH ISOLATED EMBEDDED
THUNDERSTORMS OVER THE BIG ISLAND AND MAUI AND ACROSS WATERS TO
THE NORTHEAST BEYOND 30N. THE MOST ACTIVE PORTION OF THIS CLOUD
SHIELD HAS MOVED ABOUT 150 MILES NORTHEAST OF THESE ISLANDS. THIS
FEATURE HAS ALSO TAPPED DEEP TROPICAL MOISTURE...BRINGING A LARGE
AREA OF SCATTERED TO BROKEN LAYERED CLOUDS BETWEEN 10N AND THE BIG
ISLAND THAT HAS THINNED TODAY. A LINE OF LOW LEVEL CONVERGENCE IS
PRODUCING SCATTERED THUNDERSTORMS TO THE EAST AND SOUTHEAST OF THE
BIG ISLAND WITHIN 125 MILES OF A LINE FROM 14N149W AND 19N152W.

ACROSS THE MAIN HAWAIIAN ISLANDS...A NARROW BAND OF BROKEN LOW
CLOUDS WITH TOPS TO ABOUT 5C...ROUGHLY 11000 FT...RUNS THROUGH THE
KAUAI CHANNEL AND CONTINUES TO THE NORTHEAST. THIS NEARLY
STATIONARY AREA MARKS A SURFACE TROUGH THAT HAS DRIFTED EASTWARD
TODAY. DUE TO THE PROXIMITY OF THE SURFACE TROUGH AND SOME
AFTERNOON HEATING...KAUAI IS MOSTLY COVERED WITH BROKEN LOW
CLOUDS. ON OAHU AND MOLOKAI...SCATTERED TO LOCALLY BROKEN LOW
CLOUDS ARE OBSERVED OVER INTERIOR SECTIONS. LOW CLOUD FEATURES
ACROSS THE REST OF THE STATE ARE OBSCURED BY LAYERED CLOUDS.

ACROSS THE REST OF THE REGION...A TRADE WIND FLOW DOMINATES...WITH
THE EXCEPTION OF A SURFACE TROUGH TRIGGERING SCATTERED
THUNDERSTORMS OVER AND SOUTH OF MIDWAY ATOLL.
