    Water vapor images showed a trough of low pressure N the middle atmosphere deepening toward the main Hawaiian islands from the northwest. A cloud band associated with a front supported by the trough was located within 100 miles of the line from 30°N 159°W to 26°N 160°W and further north, and within 75 miles of the curve from 27°N 161°W to 22°N 165°W to 20°N 180 and further west. This feature consisted mostly of deep cloud layers with embedded thunderstorms north of about 26°N 161°W, but thinning low to middle cloud layers southwest of that point. This feature moved southeast at 10 to 15 miles an hour. Moderately packed cold-air cumuli prevailed northwest of the band.

    To the northeast, water vapor images showed a shallower trough of low pressure in the middle atmosphere located near 25°N 145°W. Thin high cloud layers associated with this trough partly to mostly obscured lower features within 125 miles of the line from 27°N 147°W to 20°N 142°W.

    To the south, light thunderstorm activity continued in the ITCZ from 12°N to 05°N. Layered middle to high debris clouds from this and earlier convection obscured lower features partly to mostly from 12°N to 04°N across most of the area, and as far north as 20°N east of 152°W. A stream of thin high cloud layers also extended within 50 miles of the line from 17°N 160°W to 12°N 173°W.

    Otherwise, cloud cover across Hawaiian waters consisted mainly of loose clumps and streams of marine stratocumuli and cumuli east of the curve from 30°N 155°W to 22°N 159°W to 18°N 161°W to 11°N 148°W to 13°N 140°W. These streams curved from southeast toward the northwest and then the north. Individual small cumuli also were present throughout, and west of 160°W generally moved toward the west southwest at 15 to 20 miles an hour. All these clouds typically rose to heights of 7000 to 10000 feet.

    Across the main Hawaiian islands, cloud cover consisted mostly of marine stratocumuli over Oahu and Molokai, though significant quantities of cumuli also formed over Kauai and moved onto that island from the west. Limited afternoon cumulus buildups with their layered debris clouds also were present around the state, mainly over the Big Island. These clouds generally rose to heights of 8000 to 10000 feet. Radar data from near the islands showed scattered showers over southwest Kauai, and well offshore to the southeast of the Big Island, but isolated showers at most elsewhere.
