Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message
Sat, 02 Oct 2010 00:00:00 -0500

Based on data through 0430 UTC October 02 2010.

A weak surface trough has begun to move away from the islands toward the west and southwest, though plenty of low clouds linger below 10 thousand feet across the area from the Kauai channel to the Big Island this early evening. This cloudiness extends just north of the isles from Oahu to the Big Island, just to the west of the Big Island, and immediately south of Maui county, Oahu, and Kauai. Showers remain embedded within some of the low clouds. On the other hand, clear to partly cloudy skies exist west clockwise through northeast of Kauai, and southeast and south of the Big Island. More clear to scattered conditions are evident in the area from 19°N to 20.5°N between 157°W and 160°W. Low cloud movement statewide is from the east to east-northeast at 10 to 20 mph, with speeds increasing across the island chain from east to west.

Another surface trough is nearly stationary east and northeast of the islands. Most of the cloudiness with the feature is currently located within 125 miles either side of line from 30°N 144°W to 25.5°N 150.5°W to 20.5°N 152.5°W. Elsewhere, a front that had been about 280 miles north of Kauai earlier in the day has dissipated. Remnant moisture from the old system is heading toward the west-southwest and is remaining far north of the islands.

Aloft above 25 thousand feet, the axis of a north to south oriented trough has moved over the Big Island and is now along a line from 23°N 154°W to 19°N 156°W to 14°N 156°W. The trough has drifted toward the west over the past 12 to 18 hours. To the west of the state, a nearly stationary ridge is along a line from 20°N 168°W to 25°N 170°W to 28°N 173°W.

Unorganized showers and thunderstorms are firing along the intertropical convergence south of Hawaii. Most of the convection is now found from 09°N to 13.5°N between 147°W and 168°W, and from 04°N to 11°N west of 168°W.
