Issued: May 03, 2015 7:30 PM HST


Based on data through 7:00 pm May 03 2015 HST


The largest feature in the central north Pacific appears to be a broad anticyclonic circulation centered near 35°N 145°W. East to west low level flow is noted south of 30°N east of 165°W, including across local Hawaiian waters. West to east flow is noted north of 35°N east of 155°W. The circulation center, actually a subtropical high, has moved eastward slowly over the past 12 hours.

A 300 to 400 mile wide band of overcast layered clouds lies west of a line from 50°N 156°W to 43°N 153°W to 35°N 156°W. This feature changes to a ragged 300 mile wide band of broken layered clouds west of a line from 35°N 156°W to 30°N 168°W to 26°N 180°W. Marking a frontal boundary, these cloud bands also mark the western flank of the subtropical high noted above.

Large patches of broken to overcast low clouds embedded within easterly trade flow are gliding across local Hawaiian waters this evening. One of these patches lies across the eastern half of the Big Island and extends northward across Maui windward waters. Overcast low clouds cover all windward and southeast-facing shores and slopes on the Big Island, as well as Kona slopes northward to Kailua-Kona. Almost all of Maui has broken to overcast low clouds. In contrast, Lanai is mostly clear. Scattered to patchy broken low clouds cover Molokai. Oahu has broken low clouds across windward slopes of the Koolau and Waianae mountains. Scattered to patchy broken low clouds cover windward and mauka sections of Kauai. Satellite loop shows low clouds moving westward across local waters in the 20 to 25 mph range, highest in the channels.
