A cloud band associated with a cold front is located over the northwest waters, and is up to 300 miles wide. The leading edge of the band extends from 30°N 167°W to 24°N 180°, or from 600 miles east-northeast of Midway atoll to 300 miles south-southwest of Midway. This band is composed primarily of broken to overcast cumulus clouds. A narrow band of towering cumulus clouds is located along the leading edge, with tops extending up to 18000 ft. The overall cloud band is moving to the east at 20 mph.

Patches of broken to overcast low clouds are located southeast of this band, and are greatest in coverage east of 160°W. These clouds are composed primarily of stable closed cell cumulus elements north of 23°N, and primarily showery open cell cumulus elements south of 23°N. Cloud motions are to the west or west- southwest at 15 to 20 mph south of 23°N, and also north of 23°N east of 146°W. Cloud motions are to the northwest at 10 to 15 mph north of 23°N west of 146°W.

Across the main Hawaiian islands, broken to overcast low clouds cover much of Kauai, and extend 40 miles offshore to the west. A larger band of broken to overcast low clouds covers most of the central islands from the Kauai channel to the Alenuihaha channel. Additional patchy areas of low clouds are also located within 100 miles offshore to the south.

On the Big Island, broken to overcast low clouds cover most of the lower slopes. The exception is across eastern coastal sections of Puna district, extending almost as far north as Hilo town, where clouds are only scattered in coverage. Otherwise the clouds along the lower slopes extend up to 8000 ft along the windward slopes of Mauna Kea and Mauna Loa, and up to 11000 ft across leeward slopes. The low clouds also extend 20 miles offshore to the west.
