Issued: Nov 26, 2014 7:30 PM HST


Based on data through 7:00 pm Nov 26 2014 HST


A decaying stationary frontal boundary is keeping an associated band of broken to overcast cumulus clouds stretching from 27°N 140°W to 17°N 154°W, with some of the low clouds reaching the windward coastline of the Big Island. This band is between 150 to 200 miles wide. Clouds tops in this band are near 9000 ft.

Closer to the islands, scattered to locally broken low clouds cover most of the windward coastlines of the smaller islands, with broken to overcast low and mid level clouds across windward and NE areas of the Big Island. Broken low clouds linger over leeward areas of the Big Island from Kona to Milolii, and near the Volcano park. Locally broken low clouds with a few showers can be observed over the SE and leeward slopes of Maui, the W Maui mountains, E Molokai, the Koolau mountains and the Waianae range. Mainly scattered low clouds prevail over Kauai county.

Elsewhere, broken cumulus and stratocumulus clouds cover much of the area. Cloud motion S of the aforementioned front and E of 160°W is generally to the SW at about 15 mph. N of the front and E of 160°W cloud motion turns to the SE and S at 15 to 20 mph, while W of 160°W is mainly to the W at around 15 mph. The leading edge of a cloud band associated with a cold front extends from 30°N 154°W to 26°N 163°W to 29°N 173°W, or about 370 miles N of Kauai, composed of primarily showery cumulus cloud elements, with embedded towering cumulus elements extending up to 10000 ft.

Latest infrared and water vapor satellite imagery shows an upper level far NW of the island chain, pushing an associated area of broken to overcast layered clouds into the area between 22°N to 30°N and 170°W to 180. Cloud tops in this area of layered clouds are reaching 38 thousand feet. Another large area of broken layered clouds extends between 11°N to 18°N and 160°W to 180 with embedded showery lines of cumulus and TCU clouds.

Far S of the islands, deep convection can be observed along most of the intertropical convergence zone, or ITCZ. A large cluster of active thunderstorms extends between 05°N to 10°N and 140°W to 150°W. Two other clusters extend between 06°N to 11°N and 160°W to 180. Cloud tops along the ITCZ range from 48 to 52 thousand feet.
