    Water vapor imagery showed an upper low forming near 17°N 165°W. An upper level trough extended south from the low to 14°N 165°W then southwest to near 11°N 170°W. The trough and low were nearly stationary.

    The southerly winds on the east side of the trough and low were drawing cirrus clouds up from the deeper tropics and spreading them over onto the islands. These high clouds were flowing north to the islands before veering eastward. Broken cirrus clouds were common from 10°N to 18°N between 156°W and 164°W. Scattered to broken cirrus occupied the area from 18°N to 22°N between 163°W and 140°W.

    Large streaks of broken cirrus were also noted far northwest of the state within an area bounded by points 23°N 175°W, 27°N 176°W, 35°N 150°W and 32°N 150°W. The cirrus in this area was streaming toward the east northeast.

    Meanwhile, persistent trade winds continued to sweep random patches and clusters of low clouds westward into the Hawaiian islands. Near the state, the low clouds were moving west at 20 to 25 miles an hour.

    At 2 pm, there appeared to be an even mix of mostly sunny and mostly cloudy skies over each island within the chain. The cloudiest area was along the Kona and Kau slopes on the lee side of the Big Island.
