Hawaiian Islands Satellite Interpretation Message
Tue, 23 Nov 2010 23:30:00 -0600
Based on data through 0500 UTC November 24 2010.
Water vapor imagery shows the central Pacific dominated by an upper level ridge. The ridge axis extends from 38°N 152°W to 19°N 169°W and the effects cover an area from 30°N to 10°N between 143°W and 172°W. To the west of this ridge, an upper level jet is crosses the dateline near Midway atoll and marks the eastern flank of an eastward moving deep upper level trough.
The trough is producing a deck of layered clouds covers the north and west of a line from 18°N 173°E to 38°N 160°W. The location of this cloud deck has moved little over the past six hours. Isolated embedded thunderstorms are located within this band, mainly between 25°N to 29°N and 177°W to 175°E. The highest cloud tops are near 50 kft with these storms.
Around the main Hawaiian islands, scattered open celled cumulus clouds cover much of the windward waters. Leeward waters have a few low clouds overhead, with the exception of plume clouds leeward of Maui and the Big Island. On Kauai, scattered clouds cover the island interior. Oahu is mostly clear with some cloud build ups over the Koolau range. Molokai has clouds across the windward side while Lanai has clouds over the south central part of the island. Maui has low clouds over the west side as well as the southern slopes of Haleakala. The Big Island has clouds over most of the lower slopes around the island. Isolated windward showers are observed on radar, concentrated mostly over the eastern half of the state.
Far south of the Hawaiian islands, scattered thunderstorms are present along the ITCZ with tops near 50 kft.
