Hawaiian Islands Satellite Interpretation Message
Wed, 15 Dec 2010 23:00:00 -0600
Based on data through 0430 UTC December 16 2010.
Low cloud ceilings this early evening are mainly confined to upslope areas of the Big Island and the west-facing slopes of Haleakala in east Maui. Also, scattered to broken thin high clouds moving from the north and northwest are overspreading the aloha state. Skies are otherwise clear to partly cloudy below the higher cloudiness. Low cloud movement is from the east near 15 mph just east of the Big Island and veers slightly to the east-southeast near 10 mph moving up the chain to Kauai.
Except for an area of broken low clouds passing by southeast and south of the Big Island, conditions are clear to scattered in the adjacent coastal waters, discounting any high-level cirrus clouds.
A weak front is far north and northeast of the state, and is made up of broken to overcast low clouds. At the moment, most of the cloudiness is north of a line from 30°N 131°W to 27°N 136°W to 26°N 140°W to 26°N 150°W to 30°N 154°W. The part of the front directly north of the Big Island is moving away toward the north and east. A stronger front is far west of the islands and has been nearly stationary. The system is generating broken to overcast multilayered cloudiness with embedded showers and thunderstorms within 200 miles either side of a line from 30°N 166°W to 20°N 174°W to 10°N 179°W. This boundary is currently east of Midway atoll, where conditions recently have been few low clouds, unlimited visibility, and winds from the west to west-northwest near 10 mph gusting to 15 to 20 mph.
Convection has been fairly weak along the intertropical convergence zone far south of Hawaii. Most of the showers and thunderstorms have been firing from 06°N to 10°N between 140°W and 172°W, with more activity located from 10°N to 12.5°N between 143°W and 149°W.
