Water vapor imagery shows an upper level trough with an axis from 30°N 163°W to 18°N 168°W. Scattered strands of cirrus clouds are located along the eastern flank of the upper trough.
Meanwhile, a stationary front is located along a line from 30°N 151°W to 17°N 167°W. The front is characterized as a 200 mile wide band of overcast cumulus clouds. An area of layered and towering cumulus /tcu/ clouds are located along the front north of 26°N. High TCU cloud tops are up to 31 kft. To the north and west of the front, broken stratocumulus clouds cover an area that extends past north of 30°N and west of the dateline. These clouds are traveling southwest 25 to 35 mph.
Across the main Hawaiian islands, the front is impacting the central portion of the state with overcast skies and numerous showers. Broken to overcast skies are impacting all of the smaller islands this afternoon with the bulk of the showers moving north to south over Maui county. On the Big Island, broken clouds cover most of the interior areas. The Hamakua and Kona coasts have the largest breaks in the cloud cover while the surrounding waters are mostly sunny.
