The Big Island, acting like a big wedge, was splitting the low level flow. Clouds south of the Big Island were turned to the southwest while those to the north were diverted to the northwest. The clouds were scooting along at 20 to 25 mph. Cloud tops were up to 7000 feet.
At this writing, most of the Big Island below 7000 feet was blanketed by broken to overcast clouds, while the tall volcanoes and the saddle between were under mostly clear skies.
Broken to overcast low clouds covered east Maui, and the coastal waters north of Maui, Molokai and Oahu. Another area of broken to overcast clouds extended from just south of Oahu some 125 miles further to the south. Except for scattered to broken clouds over higher terrain, Kauai and Lanai were under mostly clear skies.
Water vapor imagery showed an upper level low centered about 500 miles south of the Big Island and moving slowly to the west. High clouds were wrapping around the low, mostly to the east and northeast of the low center. The northern edge of the high clouds was just south of the Big Island.
Far off to the northwest was a cold front that ran from 30°N 171°W southwestward through 26°N 180°W. The frontal cloud band was about 200 miles wide behind or northwest of the front. The front was moving slowly to the east.
