Issued: Jan 30, 2015 7:00 PM HST


Based on data through 7:00 pm Jan 30 2015 HST


Low ceilings this early evening are concentrated over northern and eastern portions of the isles. Broken to overcast low clouds are also evident over the west-facing slopes of Haleakala in east Maui, and the mountain slopes in Kau, Kona and south Kohala on the Big Island. Skies are otherwise clear to partly cloudy. The lowest clouds appear to be drifting from the north and northeast across the aloha state, but somewhat higher cloudiness is moving from the south to southwest at 10 to 15 mph on average.

Areas of broken low clouds exist northeast clockwise through west of the Big Island, north of Maui county and south of Maui, and north and northeast of Kauai and Oahu. Conditions are nearly clear elsewhere over the adjacent coastal waters.

A slow-moving front is weakening north and northeast from the state. Most of the broken to overcast low clouds associated with the boundary are located west of a line from 30°N 144°W to 25°N 150°W to 22.5°N 155.5°W. The far side of this cloudiness is along a line from 30°N 149°W to 27°N 154°W to 24°N 159°W. More low clouds ahead of the system are found north of 24°N between 141.5°W and 144°W.

The axis of a jet stream is northwest and north of the Hawaiian islands. Winds in this jet core are mainly over 100 mph as they streak from west to east. Based on water vapor imagery and the most recent GFS model run, the axis is roughly along a line from 25°N 180° to 27°N 170°W to 30°N 157°W. It then heads toward the northeast as it begins to rotate counterclockwise around a powerful upper low near 44°N 154°W as of bulletin time.
