Hawaiian Islands Satellite Interpretation Message
Thu, 28 Oct 2010 00:30:00 -0500
Based on data through 0500 UTC October 28 2010.
Water vapor imagery shows a weakening east to west oriented upper level trough centered about 275 miles west of Kauai. This low is drawing further to the west and is pulling a narrow band of scattered high clouds which extends across most of the main Hawaiian islands this evening. These high clouds are generally moving off toward the west with the exception of the clouds just east of the Big Island which are moving in a northerly direction.
An east to west oriented band of low clouds is seen moving westward in a rather strong trade wind environment. This band of clouds is primarily taking aim at windward portions of the main Hawaiian islands and is bounded between 19°N to 23°N and far upstream into the eastern central Pacific. Radar is showing widely scattered showers on radar, mostly hitting windward and mauka areas, with occasional showers carrying over to leeward sides. About 300 miles north of Honolulu is a band of stratus and stratocumulus clouds associated with a cold front advancing to the south. This band of clouds is 175 miles wide extending along an axis from 34°N 133°W to 27°N 151°W to 35°N 168°W.
Far south of the state along the ITCZ is a large band of widely scattered thunderstorms that are in an area from 05°N to 12°N and 139°W to 177°W with tops extending to 49 kft. Some high cirrus clouds are being blown off the tops of these thunderstorms to the north but they presently remain well to the south of the state.
