    Since mid-afternoon an east northeast to west southwest band of overcast high clouds has moved southeast and now obscures lower level features from Lanai to the Big Island of Hawaii. Based on visible imagery through 500 pm low-cloud cover has changed little since mid-afternoon. Broken to overcast low clouds cover most windward areas of the main Hawaiian islands and broken low clouds are spreading leeward on Oahu and Molokai. The clouds over central Oahu are wave clouds, a series of narrow cloud lines parallel to the Koolau mountains. Low clouds are scattered over the west third of Kauai, along the leeward coast of Oahu from Pearl Harbor to kalaeloa to kaena point, over the west quarter of Molokai and over the leeward coast of Maui. Broken low clouds from afternoon heating covered the leeward slopes of the Big Island through 500 pm.

    A lot of the cloud cover around the main Hawaiian islands is associated with the trailing ends of two old frontal bands. One band is southeast of a line from 24°N 140°W to 20.5°N 150°W over the Big Island to 17°N 169°W. The band is 120 miles wide and contains showery broken to overcast low clouds. The second band is northwest of a line from 25°N 140°W to 22°N 150°W over the Kauai channel to 20°N 164°W to 22°N 170°W to 27°N 174°W. Over the past several hours the parts of the two bands near the main Hawaiian islands have remained nearly stationary. Northeast of the islands the two band have become less well defined and difficult to separate. In any case, there are broken to overcast low clouds upstream of the main Hawaiian islands. These clouds are a mix of showery cumulus clouds, cu, and stable stratocumulus clouds, sc. The clouds upstream of the Big Island, part of the southern band described above, are the most showery looking.

    An area of broken layered cloud and numerous cumulonimbus clouds, CB, associated with a frontal cloud band is northwest of a line from 30°N 175°W to just northwest of Midway atoll to 26°N 180°W. The band has been moving toward the east southeast at 30 mph.

    A strong jet stream runs from 16°N 170°W over Oahu to 23°N 152°W to 23°N 140°W. There is a band of broken high clouds south of the jet west of 148°W. The northwest edge of the high-cloud band over the main Hawaiian islands has been moving toward the east southeast at 30 mph.
