    Latest regional satellite images show broken to overcast showery cumulus /cu/ clouds moving over the main Hawaiian islands from the east, with these clouds piling up along windward coasts and slopes. Low clouds near the islands are moving toward the west at speeds near 27 mph.

    On Kauai, broken to overcast low clouds are over the interior and windward portions of the island, while the leeward coast has few to scattered low clouds. Niihau currently has sunny skies. Most of Oahu is covered in broken to locally overcast low clouds, except the southwest portion of the island, where skies are mostly sunny. In Maui county, Molokai is covered in broken low clouds, with showery cu along the windward slopes and stable stratocumulus over the leeward portion of the island. Broken to overcast showery cu are banked along windward slopes of Maui, but the remainder of the island is under few low clouds and mostly sunny skies. On the windward side of the Big Island, scattered to locally broken low clouds prevail from just north of Hilo to near Volcano, with mostly sunny skies, and few to no low clouds, elsewhere over the island.

    While the low cloud field near the islands is dominated by showery open-celled cu elements, further to the east and northeast, the cloud field is dominated by closed-cell stable stratocumulus elements, with this cloud field prevailing from 22°N to 30°N between 155°W and 140°W. Water vapor imagery shows the islands well south of the polar jet, which is located north of the area north of 34°N, with a relatively stagnant flow aloft over the main Hawaiian islands. A weak northeast to southwest oriented trough aloft is located just northwest of Kauai, and moving toward the southeast, while a dissipating trough aloft is seen about 300 to 400 miles east of the islands along 150°W. A large high aloft is centered west of the date line, and an associated ridge aloft extends northeastward over Midway atoll and the northwestern Hawaiian islands.
