Based on data through 1800 UTC October 24 2010.
Low clouds were scattered to broken over east facing mountain slopes of Kauai, the length of the Koolau mountains,,,the sea cliffs of Molokai, the eastern half of the west Maui mountains, and along the coast from Hana southward. The rest of the smaller islands had clear skies.
The Big Island had three spots with broken clouds, along the Kona coast near Milolii, the windward Kohala mountains, and the Hilo and Puna districts. The rest of the island Sat under clear skies.
Clouds north and east of the islands were gathered into clusters separated by clear skies. The clusters were east-northeast of Kauai, north of Oahu, north of Maui, north clockwise through south of the Big Island. Some of the clouds appeared to be depositing isolated showers.
Skies south and west of the islands had a totally different appearance. Instead of clusters, broken to overcast clouds were organized along wiggly lines. The most noticeable lines extended west of the south Kona coast and southwest of makena Maui. A mix of clear skies and scattered clouds were observed elsewhere within 80 miles south and west of the islands.
The low clouds were moving to the west at 15 to 20 mph, with speeds decreasing moving from east to west up the chain. Cloud tops ranged from 5 to 6 thousand feet.
Aloft above 25 thousand feet, a weak low was centered about 250 miles south of Honolulu near 18°N 157°W and was moving west at 15 mph. The low was setting off isolated thunderstorms within 120 miles east and west of 13°N 158°W. A small cluster of showers and thunderstorms was also evident near 16.5°N 163.5°W, or 500 miles southwest of Honolulu. Additionally, high clouds were streaking north and northeast in the area east clockwise through south of the low. The upper low had no noticeable effect on the low clouds around the islands.
Unorganized showers and thunderstorms were scattered along the intertropical convergence zone in an area from 05°N to 10°N between 140°W and 180°W. The tallest thunderstorms with tops above 50 thousand feet were located west of 155°W.
