FEATURE...A SURFACE COLD FRONT BOUNDARY...ALSO EXTENDS AROUND THE
SAME LINE. TWO CLUSTERS OF TOWERCUMULUS CLOUDS AND VERY ACTIVE
THUNDERSTORMS CAN BE OBSERVED JUST N OF MAUI AND ABOUT 100 MILES N
OF HILO. HIGHEST CLOUD TOPS IN THESE THUNDERSTORMS ARE REACHING 41
THOUSAND FEET.

CLOSER TO THE ISLANDS...THICK LAYERED CLOUDS COVER THE BIG ISLAND
AND OBSCURING LOW LEVEL FEATURES...WITH BROKEN CUMULONIMBUS CLOUDS
