Water vapor images showed a trough of low pressure in the middle atmosphere over and just southeast of the main Hawaiian islands. Dense layered high to middle clouds streamed out of the ITCZ along the southeast edge of the trough, mostly to completely obscuring lower features within 350 miles of the line from 23°N 144°W to 07°N 163°W.

To the northwest, layered high to middle clouds associated with a front located well north of 30°N partly to mostly obscured lower features north of the curve from 30°N 166°W to 25°N 171°W to 25°N 178°W to 27°N 180.

To the south, very light thunderstorm activity continued in the ITCZ from 07°N to 04°N, mainly east of 158°W. Layered high to middle debris clouds from this and earlier convection partly to mostly obscured lower features from 10°N to the equator.

Otherwise, cloud cover across Hawaiian waters consisted mostly of marine stratocumuli and low to middle stratus layers, though individual small cumuli also were present throughout. These clouds generally rose to heights of 8000 to 12000 feet, though some of the higher stratus layers approached 15000 feet. The clouds were organized mainly into a mass of nearly solid stratus within 200 miles of the line from 27°N 178°W to 28°N 163°W, and loose clumps roughly within 250 miles of the line from 21°N 180 to 21°N 140°W. South of about 24°N, they generally moved toward the west at 15 to 20 miles an hour, while north of 24°N, they moved toward the east northeast at around 15 miles an hour.

Over the main Hawaiian islands, cloud cover consisted about equally of layered debris clouds from afternoon cumulus buildups over higher terrain inland, and marine stratocumuli moving ashore along slopes facing north clockwise through southeast. Areas with the least cloud cover were limited mainly to south Kauai, south and central Oahu, the west two thirds of Molokai, coastal Lanai, west slopes of the west Maui mountains, the central isthmus of Maui, the summit and south slopes of Haleakala on Maui, the west coast of north and south Kohala districts on the Big Island, the vicinity of South Point on the Big Island, and the interior uplands of the Big Island above elevations of about 5000 feet. Radar data from near the islands showed isolated showers at most.
