Overcast layered clouds cover the central north Pacific north of 32°N, east of 165°W and south of a line from 50°N 165°W to 40°N 140°W. Marking a frontal boundary, these clouds are moving toward the east at about 15 mph. A 120 mile wide band of broken to overcast low clouds marks this frontal boundary farther to the west, north of a line from 30°N 165°W to 24°N 180°W.
A weak subtropical ridge extends through 28°N 140°W, 23°N 160°W and 21°N 180°W, just north of the main Hawaiian islands. Satellite loop shows low level flow south of the ridge axis is generally from east to west, while southwesterly and westerly flow is noted north of the ridge axis. Broken stable low clouds persist east of a line from 16°N 140°W to 24°N 150°W to 28°N 140°W. Additional broken low clouds cover windward and southeast Hawaiian local waters, as well as a broad area west of 165°W and south of 18°N. Isolated cumulonimbus, CB, continue to fire south of a line from 05°N 152°W to 05°N 162°W to 08°N 172°W. More CB cover an area west of 176°W and south of 03°N.
Low clouds cover windward and southeast portions of the Big Island and Maui. The remaining islands appear to have scattered low clouds to clear skies. Low clouds have pushed far into the Big Island island interior and into the saddle. Satellite loop shows that low level flow, though generally from east to west, has veered a bit across windward waters since yesterday. Winds remain in the 15 to 20 mph range.
