Water vapor imagery shows an upper level low centered about 800 miles west southwest of Kauai. An upper ridge dominates the rest of the area, except for a southwesterly upper level jet crossing the far northwest Hawaiian islands.
Infrared imagery shows scattered thunderstorms in a 200 mile wide band from 30°N 168°W to 23°N 180°W. These thunderstorms have cloud tops from 30000 to 45000 feet and are embedded within layered low and mid clouds. Scattered thunderstorms with tops to 50000 feet are found along the intertropical convergence zone between 5°N and 10°N west of 160°W. A band of low topped clouds along a weak frontal boundary is located about 170 miles northeast of the main Hawaiian islands, and this band is moving southwest at 10 to 15 mph.
Across the main Hawaiian islands, broken low clouds are found in the typical trade wind pattern areas, covering windward Big Island and Puna district, windward Haleakala on Maui, Koolau mountains and eastern half of Kauai. Low clouds are scattered elsewhere across the state. Cloud movement is towards the west at about 15 mph.
