Hawaiian Islands Satellite Interpretation Message
Mon, 18 Oct 2010 00:30:00 -0500
Based on data through 0500 UTC October 18 2010.
High pressure is centered far NE of the islands near 35°N 145°W and extends a ridge toward WSW. The ridge extends from 30°N 150°W across to 25°N 170°W. Low clouds south of the ridge are moving east at 10 to 20 mph, while north of the ridge low clouds are moving NW at 5 to 10 mph. Low clouds are mostly scattered across the tropical and subtropical central Pacific with a few patches of broken clouds mixed in.
An upper level trough stretches from 30°N 150°W to the southwest over 20°N and the dateline. The low is enhancing some low level cloud growth near 28°N 152°W and also near 20°N 170°W where isolated towering cumulus can be seen on IR satellite imagery.
The subtropical jet is producing layered mid and upper level clouds from the dateline to 165°W between latitudes 8°N and 20°N. The jet meanders across the central Pacific between 10 and 20°N and is creating a smaller areas of mid and upper clouds near 17°N 141°W along with isolated thunderstorms with tops reaching 38 thousand feet.
Kauai, Oahu, Molokai and Lanai all have mostly clear skies this evening with the exception of the Koolau mts where partly cloudy skies prevail. Maui and the big islands have mostly cloudy skies with patches of partly cloudy skies near the coasts of Maui, and the leeward upslope areas of the Big Island.
