Based on data through 0500 UTC January 13 2011.

A vigorous cold front was making its way over Kauai at sunset this evening. The front was moving quickly east at just over 30 miles an hour. Scattered thunderstorms and numerous showers were occuring along and out to 180 miles east of the front. Tops of the thunderstorms near the islands were mostly between 35000 and 38000 feet. Higher storm tops were noted north of the state beyond 25°N.

The most active weather and unstable clouds occupied the area out to around 250 miles east of the front between 20°N and 30°N. The broken to overcast cloudiness further east beyond this main frontal cloud band, and east of a line from 30°N 143°W to 20°N 151°W were made up of mostly broken to scattered low clouds and broken to overcast high level cirrus clouds. However, there were some showers and isolated thunderstorms embedded within this area as well.

The frontal cloud band was obscuring Kauai and Oahu. Maui county and the Big Island were seeing some cloudiness as well but not as much as Oahu and Kauai. But the frontal cloud band was about to move onto Molokai at 7 pm. The waters just southwest of Maui and the Big Island were seeing mainly scattered low clouds.

The front extended from a low pressure system near 36°N 162°W southward through 30°N 155°W to 25°N 158°W to Kauai to 18°N 170°W at 6 pm. The low was moving northeast near 15 miles an hour.

The back or west edge of the frontal cloud band extended from 30°N 158°W to 26°N 160°W to 19°N 170°W. Numerous, mostly scattered low clouds were flowing southeastward into the area northwest of the front between 160°W and the dateline. Ahead of the front, scattered to broken low clouds were seen flowing northward toward the island chain near 15 miles an hour.

A 225 miles wide, broken to overcast layered cloud band along the ITCZ was centered along a line from 09°N 140°W to 08°N 150°W to 12°N 158°W to 07°N 171°W. Isolated thunderstorms were embedded within this cloud band. The thunderstorms were most numerous east of 155°W. Tops of the strongest storms were near 38000 feet.
