At 200 am HST, water vapor imagery depicted plenty of middle to upper-level dry air and northwest winds west of an upper trough that extended southwest over the state. This dry air combined with a deep layer ridge of high pressure northwest of the islands continued to support more of a suppressed environment between 20°N and 30°N from 150°W to the date line, which includes the Hawaiian islands. As a result, mainly scattered, low-topped, cumulus clouds were shown tracking southward over the state. Broken to overcast low clouds were depicted across the Big Island. Cloud tops remained below 12 thousand feet.

Farther south of the islands, a narrow band of stratus clouds with embedded thunderstorms extended west-northwest from 8°N 160°W to 15°N 180°. Maximum cloud tops associated with the thunderstorms extended up to around 50 thousand feet. Scattered to numerous thunderstorms associated with the monsoon trough were shown east of this feature between the equator and 12°N from 140°W to 160°W. Maximum cloud tops associated with these thunderstorms extended to 50 to 55 thousand feet.
