An upper level trough remains north of the islands this afternoon. Water vapor shows the trough axis extends from 42.5°N 151.7°W to 24.4°N 160.8°W, placing the southern part of the trough axis about 170 miles north northwest of Kauai at 2 pm.
The surface feature associated with the upper level system has moved little since daybreak. The leading edge of a cloud band associated with a surface front is from 36.0°N 143.9°W to 26.0°N 150.6°W to 15.9°N 164.8°W. The leading edge of the band is over Oahu at 2 pm, and the back end is just moving to the east of Kauai. Low clouds are lingering over Kauai this afternoon, but are starting to break up over the western side of the island. The cloud band combined with earlier clouds over Oahu continue to bring mostly cloudy skies to the island this afternoon.
Clouds have increased over the islands of Maui county and the Big Island since daybreak. As of 2 pm, the western side of Molokai and Lanai have the fewest clouds overhead, with clouds plentiful over the eastern half of these islands. Clouds have formed over Maui over the last six hours and cover just about the entire island at 2 pm. Similarly, clouds have formed over the Big Island, and cover most of the slopes, extending up to around 8000 feet this afternoon.
