A line of wind-convergent low clouds has been over Oahu through the day, bringing ceilings across most of the isle. Elsewhere over the island chain, low cloudiness that had been over the other isles has been dissipating, leaving clear to partly cloudy skies for the most part. Broken low clouds do remain over portions of Hamakua, Hilo, and Puna on the Big Island, and sections of central Molokai. Low cloud movement is from the south to southwest at 15 to 20 mph statewide.
In the adjacent coastal waters, broken low clouds exist east clockwise through south of the Big Island, to the southwest and northeast of Oahu, and to the north of Kauai. Conditions are no worse than scattered otherwise.
A front has been dissipating near Kauai, and has been weakening north of the islands. Another system is behind the first and has been heading toward the east and southeast near 30 mph. The leading edge of broken to overcast low clouds along and ahead of this boundary is along a line from 30°N 155°W to 25.5°N 158°W to a point 150 miles northwest of Kauai to 23°N 165°W as of bulletin time.
The latest water vapor images show a dry environment above 25 thousand feet across much of the central north Pacific. This is especially the case from 10°N to 28°N east of 170°W.
