At 700 pm HST, satellite imagery showed a narrow cloud band associated with a dissipating frontal boundary extending west- southwest from 28°N 140°W to around 100 miles north of Oahu and Kauai. Cloud tops within this band were at or less than 10 thousand feet. This cloud band was moving toward the south between 150°W and 160°W and toward the east-southeast between 140°W and 150°W. A similar cloud band associated with another front was entering the discussion area from the north between 140°W and 160°W.

Scattered to broken low-level cumulus clouds were shown tracking toward the west-southwest at 15 to 20 mph within the trade winds over and around the main Hawaiian islands. The bulk of these clouds were focusing over the windward areas with isolated to scattered coverage shown spilling over to the leeward sections. Maximum cloud tops extended into the 10 to 15 thousand foot range. Scattered high clouds, mostly transparent, were shown quickly tracking toward the east-northeast within the subtropical jet across the state. Broken to overcast low clouds were shown over the leeward section of the Big Island from Kona to South Point.

Scattered thunderstorms were shown across the deep tropics between 7°N and 15°N from 150°W to the date line. Maximum cloud tops extended to around 55 thousand feet. A general motion toward the west was shown, except for the activity between 170°W and the date line where the storms continued to develop in the same general area with little motion depicted.
