BASED ON DATA THROUGH 1200 UTC DECEMBER 08 2016

AT 200 AM HST...WATER VAPOR IMAGERY SHOWED AN AMPLIFIED UPPER
PATTERN ACROSS THE DISCUSSION AREA THAT WAS CHARACTERIZED WITH AN
UPPER TROUGH EXTENDING SOUTH BETWEEN KAUAI AND THE DATE LINE AND AN
UPPER RIDGE AXIS EXTENDING NORTH-NORTHEAST BETWEEN THE BIG ISLAND
AND 140W. MID TO UPPER SOUTHWEST FLOW EAST OF THIS UPPER TROUGH WAS
DRAWING A LARGE PLUME OF MOISTURE NORTHEASTWARD FROM THE DEEP
TROPICS ACROSS THE MAIN HAWAIIAN ISLANDS TO 30N 145W. THIS MOISTURE
COMBINED WITH THE UPPER TROUGH AND A WEAK SURFACE TROUGH NEAR AND
NORTHEAST OF THE BIG ISLAND CONTINUED TO SUPPORT A LARGE SHIELD OF
BROKEN TO OVERCAST LAYERED CLOUDS EXTENDING NORTHEAST FROM AROUND
10N 170W TO THE MAIN HAWAIIAN ISLANDS TO 30N 145W AND BEYOND.
EMBEDDED THUNDERSTORMS WERE BEGINNING TO DEVELOP OVER THE HAWAIIAN
WATERS WITH TOPS EXTENDING TO AROUND 40 THOUSAND FEET. ANOTHER BATCH
OF STORMS WERE APPROACHING MAUI COUNTY AND OAHU FROM THE SOUTH.
OVERCAST CONDITIONS PREVAILED OVER THE ISLANDS DUE TO THIS LARGE
SHIELD OF CLOUDS. THE BACK EDGE OF THIS CLOUD COVERAGE WAS A FEW
HUNDRED MILES WEST OF KAUAI. THE UPPER TROUGH SUPPORTING THIS CLOUD
COVERAGE WAS SLOWLY MOVING TOWARD THE EAST-NORTHEAST.

SCATTERED TO BROKEN LAYERED CLOUDS...MOSTLY UPPER CLOUDS...WERE
SHOWN ADVANCING EASTWARD OVER MIDWAY ISLAND AHEAD OF THE NEXT
FRONTAL SYSTEM APPROACHING.
