Hawaiian Islands Satellite Interpretation Message
Mon, 27 Sep 2010 13:30:00 -0500
Based on data through 1800 UTC September 27 2010.
Water vapor imagery shows an upper level trough centered near 20°N 165°W or 400 miles west southwest of the main Hawaiian islands. This trough is moving west at 20 mph. An upper level jet on the southeast side of the trough is lifting high level moisture north from the tropics across the area south of 20°N between the trough and 150°W. An upper ridge dominates from the Hawaiian islands east.
A large frontal cloud band stretches across the northern portion of the area. The 200 mile wide cloud band stretches from 30°N 153°W to 27°N 160°W to 25°N 170°W to 27°N 180°, crossing the northwest Hawaiian islands between French Frigate Shoals and lisianski. The clouds with this band are mainly low topped cumulus with highest tops near 12000 feet. About 250 miles south of the main cloud band there is another narrower cloud band which eventually merges with the main frontal band near 30°N. North of the frontal band, broken cold air cumulus covers the region.
Scattered thunderstorms are found embedded in broken cloud layers along the intertropical convergence zone south of 13°N between 150°W and 170°W. Highest cloud tops are near 50000 feet.
Over the main Hawaiian islands, skies are mainly clear. Only broken low clouds are found over eastern Puna district and coast on the Big Island, the Hana coast of eastern Maui, and along the windward coast of Oahu and Kauai. More low clouds are found over the windward coastal waters and in a large plume of clouds located about 100 miles west of Kona on the Big Island and 80 miles south of Oahu. Cloud motions were to the southwest at about 10 mph.
