At 700 pm HST, water vapor imagery showed plenty of middle to upper moisture spilling north and northeast ahead of an upper trough several hundred miles northwest of the state. This upper trough combined with a surface frontal boundary continued to support broken to overcast layered clouds between 27°N and 30°N from 155°W to the date line. These clouds were progressing toward the east.
Scattered patches of cumulus clouds were shown tracking toward the west and northwest within the trade winds over and around the main Hawaiian islands. A large patch of cumulus clouds was depicted approaching Maui county and the Big Island between 20°N and 23°N from 152°W to 155°W. Scattered low clouds were shown over Kauai. Scattered to broken low clouds were shown across portions of Oahu, mainly over the koolaus and the adjacent waters to the west across the Kauai channel. Broken low clouds were focusing across portions of Maui county and the adjacent waters. Broken to overcast low clouds were depicted over the Big Island, excluding the summits and the coastal sections of the Puna district where mostly clear to partly cloudy conditions were shown. Another large patch of cumulus clouds was located southwest of Oahu between 20°N and 22°N from 158°W and 159°W. Maximum cloud tops over and around the islands associated with these clouds ranged from 10 to 20 thousand feet.
