    Water vapor imagery shows an elongated east northeast through west southwest oriented upper trough with it axis lying just to the north of the state. The trough has been nearly stationary over the past several hours. Just a few high thin cirrus clouds are seen moving toward the northeast on the south side of the trough through most of these remain southwest of the main Hawaiian islands.

    An old frontal boundary extends from near 30°N 141°W to 24°N 150°W to 23°N 160°W. The band has been moving very slowly to the south over the past several hours. The band consists of mainly cumulus and stratocumulus clouds. The band is about 60 miles wide and rather ragged in appearance. The southern edge of the band lies just to the north of Kauai.

    Cloud coverage over the islands has increased immensely over the past several hours mainly due to daytime heating of the land surfaces. Over Kauai low clouds are covering most interior and southern areas of the island while north and northeast coastal being basically clear. Over Oahu low clouds have built up over the slopes and summits of the Koolau range with some clouds also seen over central portions of the island. Just a few patches of low clouds are seen over interior Lanai as well as over interior areas of Lanai. Over Maui low clouds are banked up over the southern and southwestern slopes of Haleakala as well as over portions of the west Maui mountains. Over the Big Island low clouds are banked up over most of the Kona and Kau slopes with scattered low clouds seen over the Hilo and Puna districts.

    Just scattered patches of low clouds are seen over the open waters to the south of the state and over the waters surrounding portions of the Big Island coastal waters.

    A couple areas of thunderstorms are seen along the ITCZ far to the southeast of the state with another area of thunderstorms seen far to the southwest of the state associated with a weak trough of low pressure. These areas of thunderstorms are generally moving off toward the west at around 10 mph.
