Hawaiian Islands Satellite Interpretation Message
Sat, 23 Oct 2010 13:30:00 -0500
Based on data through 1800 UTC October 23 2010.
A weak high pressure center located near 25°N 140°W extends a ridge of high pressure along 25°N that stretches across the central Pacific. South of the ridge, between the equator and 20°N, low clouds are moving 10 to 25 mph toward the west. From 25°N to 30°N, low clouds are moving toward the east at 10 to 20 mph between 140°W to 170°W. From 170°W to the dateline, low clouds are moving 10 to 20 mph toward the northeast as the low level flow turns clockwise around the ridge. Low cloud cover is scattered across most of the area with small patches of broken cloud cover.
The water vapor channel shows zonal flow aloft with the polar and subtropical jet moving west to east across the central Pacific. The polar jet is creating a mass of layered mid and upper level clouds covering the area between 33°N and 40°N.
For the islands, skies are mostly clear over the entire state this morning except partly cloudy skies over windward Kauai, the Koolau mts, extreme eastern Molokai, and windward areas of Maui. Scattered low clouds over the windward waters light are moving along with the light SSE flow. Scattered low clouds over the leeward waters are moving west.
Far south of the islands, isolated thunderstorms are located within the intertropical convergence zone between 7°N to 11°N between 140°W and the dateline.
