The last few visible images of the day reveal mostly clear skies over Maui county and the Big Island, with partly cloudy skies further west over Oahu and Kauai. Over the Big Island, small patches of low clouds are present over the Hamakua coast southward into the Hilo and Puna areas, while on the Kona coast a few patches of low clouds on the slopes appear to be dissipating at sunset. Clear skies prevail over the remainder of the Big Island. On Maui, patches of low clouds are present over the west Maui mountains and on the windward slopes of Haleakala, otherwise clear skies prevail. Clear skies also prevail over Lanai and Molokai, except for a small patch of low clouds over the eastern tip of Molokai. Over Oahu, broken low clouds are present over the Koolau range, with scattered cloudiness over the remainder of the island. Scattered to broken low clouds are also present over the entire island of Kauai, with clouds most prevalent over the higher interior terrain. Across the coastal waters around Hawaii, scattered to broken stratocumulus are moving to the west southwest near 15 mph within the trade wind flow, and highest cloud tops are near 7 thousand feet.

Far to the northeast of Hawaii, a band of layered cloudiness along a weak cold front is located within 100 miles of a line from 27°N 140°W to 25°N 145°W. This band is moving slowly to the southeast, with highest cloud tops extending up to 35 thousand feet. Further to the west, a 100 mile wide band of broken stratocumulus associated with the dissipating tail end of the same front extends from 25°N 145°W to 24°N 152°W. Another band of stratocumulus, associated with the remnants of a dissipated front, lies along a line from 22°N 144°W to 17°N 154°W to 14°N 163°W. This band is 50 to 100 miles wide and is moving to the southwest at 10 to 15 mph within the trade wind flow.

Over the far northwestern Hawaiian islands, a thick band of broken to overcast low and mid level cloudiness lies north and west of a line from 30°N 170°W to 22°N 180. These clouds are associated with a cold front which is producing periods of moderate rain and gusty southwest winds over Midway atoll. This band of clouds is moving to the east at 15 to 20 mph, with highest cloud tops estimated near 15 thousand feet.

Elsewhere across the tropical central north Pacific from 10°N to 30°N between 140°W and the date line, scattered to locally broken stratocumulus are predominant, with no significant deep convection noted. Far to the south, convection associated with the intertropical convergence zone remains south of 5°N between 155°W and 180, although some cirrus cloudiness emanating from this convection is spreading northward into the discussion area between 160°W and 180 south of 15°N.
