Pushing toward the west and west-southwest, showery low clouds directly associated with a weakening front have been moving over Kauai and Oahu, while more elements south of the front have been occasionally affecting windward sections of Molokai and Maui. The southern edge of the boundary is currently along a line from 25°N 140°W to 22.5°N 150°W to 21°N 160°W to 23°N 170°W to 25°N 173°W, and has been heading south at less than 10 mph over the past six hours. Isolated thunderstorms have developed along the boundary west of 170°W. Also, broken high clouds associated with an upper low have been sweeping over Maui county from the west and northwest. Low cloud movement is from the east to east-northeast at 25 to 30 mph statewide, with somewhat higher speeds immediately north and west of Kauai.
Frontal cloudiness is generating low ceilings north of the aloha state this early evening, especially Kauai and Oahu. Scattered to broken showery low clouds are east and northeast of Maui county and the Big Island, and southeast clockwise through northwest of Kauai. Ignoring any high clouds, conditions are otherwise clear to scattered over the adjacent coastal waters.
A weak upper low appears to be centered about 70 miles north of Molokai as of bulletin time, and has been heading south at less than 10 mph. As mentioned above, high level cirrus clouds being generated by the system have been flowing over Maui county toward the east and southeast.
A weather system west of the date line continues to affect conditions east of 180. Showers and thunderstorms have been occurring north of 25°N west of 176°W. Midway atoll is occasionally seeing some of the inclement weather, with lower ceilings, reduced visibilities in rain and fog, and winds from the south near 25 mph and gusts to over 30 mph.
Convection has been firing along the intertropical convergence zone far south of Hawaii. Most of the activity has been igniting from 06.5°N to 12°N east of 150°W, and from 04°N to 11°N west of 150°W.
