Based on data through 1800 UTC December 04 2010.

An upper level low is situated about 1500 miles northeast of Honolulu this morning near 34.4°N 138.0°W. An associated upper level trough axis extends from 30°N 130°W to 20°N 156°W. The tail end of the trough is passing over the Big Island at 8 am.

Low clouds upstream of the main Hawaiian islands are moving from the east around 25 mph. Low clouds are concentrated over the east sides of the islands as a result.

On Kauai, scattered clouds cover most of the island. On Oahu, clouds are plentiful over the Koolau mountain range. Additional clouds are found over the central valley of Oahu and over the northern half of the Waianae range. Molokai has clouds over the Halawa Valley, and Lanai has clouds forming over the east facing slopes. Meanwhile, just a few clouds are noted over Kahoolawe. On Maui, clouds are plentiful over the east facing slopes of the west Maui mountains, and over the east facing slopes of Haleakala from hookipa beach park to Hana to kaupo.

The Big Island has clouds building over the east facing slopes of the Kohala mountain range at 8 am. Additional clouds are found over the slopes of the north Hilo, south Hilo and Puna districts. A few clouds are found over the Kau, south Kona and north Kona districts.

A low pressure system near 30°N and the dateline has thunderstorms associated with it. The largest concentration of thunderstorms is between 15°N and 25°N, from 170°W and the dateline.
