Water vapor imagery shows three upper level systems in the central Pacific. The system to the northeast is a complex low with a low near 43.6°N 134.6°W, about 2035 miles north northeast of Honolulu, with a shortwave passing to the south near 36.5°N 135.6. This system continues to move away from the islands this evening, with isolated thunderstorms with tops to near 37000 feet.
The next mid to upper level feature is over the main Hawaiian islands at 7 pm. Water vapor shows the mid to upper level low over Kauai, and has it lifting slowly to the north over the last several hours. The third system is about 1300 miles west of Honolulu near 22.3°N 178.3°W. This system is moving slowly to the west away from the islands.
The last visible imagery of the day shows low clouds over the southern portion of Kauai stretching over the Kauai channel and reaching the north and west parts of Oahu. Additional clouds are found over the remaining portions of Kauai and Oahu. Scattered clouds are found over Molokai, Lanai and Kahoolawe. On Maui, scattered clouds are found over the west Maui mountains, while just a few patches of clouds are found over the upper slopes of Haleakala. A larger area of low clouds is found just to the east of Molokai and Maui.
On the Big Island, just a few clouds are found near the Kohala mountains. Scattered clouds are found over the upper slopes of the Hamakua and north Hilo districts between 3000 and 8000 feet. Scattered to broken clouds cover the south Hilo and Puna districts. The clouds are thicker and cover more area in the Kau and south Kona districts at 7 pm. These clouds extend to the north into the north Kona district, but thin out as you reach the south Kohala district.
