Issued: Jul 29, 2015 8:30 AM HST

Based on data through 8:00 am Jul 29 2015 HST

Scattered to locally broken low clouds are seen moving westward upwind of the state. This is basically providing for a typical windward and mauka distribution of low clouds over the state. Over Kauai low clouds are banked up over the eastern slopes with most southern and western areas remaining cloud free. Over Oahu low clouds are banked up over the slopes and summits of the Koolau range with just a few low clouds seen elsewhere. Just a few patches of low clouds are seen over eastern Molokai and interior Lanai. Over Maui a few patches of low clouds are seen over the eastern slopes of Haleakala as well as over portions of the west Maui mountains. Over the Big Island just a few patches of low clouds are seen over the Hilo and Puna districts with a few patches of low clouds also seen over the windward Kohala slopes.

Isolated thunderstorms are associated with a low pressure system located about 800 miles southeast of Hilo. This low is moving toward the west 10 to 15 mph.

A weak trough of low pressure is seen moving westward a few hundred miles south southwest of the state. Widely scattered thunderstorms have been flaring up in its vicinity as it moves westward at around 10 mph.

Water vapor imagery shows a northeast through southwest oriented trough of low pressure centered several hundred miles to the northwest of the state. Scattered thunderstorms are associated with this upper trough as it has been nearly stationary over the past several hours.
