Hawaiian Islands Satellite Interpretation Message

Based on data through 0500 UTC October 13 2010.

Water vapor loop shows an upper level trough just to the east of the Big Island with an axis from 27°N 146°W to 14°N 159°W. Satellite derived winds indicate a 75 mph jet streak on the eastern flank of the trough. An associated surface trough has an axis from 17°N 151°W to 10°N 155°W. This system is producing a large area of dense layered clouds with isolated embedded cumulonimbus clouds with tops to 45 kft and is bounded between 08°N to 18°N and to 144°W to 156°W. Cirrus clouds from the jet stream run to the northeast of this bounded area.

Upstream of the state, an area of showery cumulus and stratocumulus clouds are located over the Hawaiian windward coastal and offshore waters. These clouds are associated with weak disturbance moving east to west at 10 to 15 mph across the state this evening. The clouds and associated showers are beginning to increase in areal coverage and move over the state. Further north is a stationary front is positioned along an axis from 38°N 142°W to 32°N 164°W to 35°N 178°W as is characterized by a 150 mile wide band of overcast stratus clouds. The associated long wave upper trough and mid and high level moisture is producing areas of layered clouds with tops around 35 kft.

Across the main Hawaiian islands, as mentioned much of the windward waters have broken clouds with embedded showers. Kauai has cumulus clouds over the most of the island this evening. Oahu also has broken clouds with some clearing across the Ewa plain. Molokai has broken clouds across the eastern half of the island with clearing over the western half. Maui has clouds across the leeward side of the island and a few clouds near Hana. The Big Island has overcast cloud build ups over most of the island interior up to 9 kft in elevation.

Far south of Hawaii in the ITCZ, numerous thunderstorms cover an area between 05°N and 14°N along the central Pacific basin. Cloud tops reach to 47 kft in height.
