Hawaiian Islands Satellite Interpretation Message
Tue, 11 Jan 2011 18:30:00 -0600
Based on data through 0000 UTC January 12 2011.
Remnant low clouds from the front that moved through the main Hawaiian islands yesterday and last night, continued to linger around Maui, Lanai, and the Big Island this afternoon. The Kona side of the Big Island has seen coverage increased in the past hour or two, as well as Molokai. These clouds would stretch northeastward across the windward waters.
The rest of the main Hawaiian islands is sitting under sunny skies. However, there are low clouds lurking nearby. A patch of low clouds is located just a few miles off the south shores of Oahu. It is moving north, and will reach land before sundown.
A field of low clouds about 600 miles long and 130 miles wide, is located further south and southwest of this patch. The leading edge is about 130 miles south of Kauai, moving north at 12 mph.
The frontal band that gave the islands a bit of weather yesterday is located between 215 and 450 miles east of the Big Island. The front extends further north, into a low pressure area at 36°N 157°W, or about 930 miles north of Kauai. The coordinates of the front are as follows, 30°N 143°W 28°N 142°W 22°N 146°W 17°N 152°W. A few thunderstorms are concentrated within 80 miles either side of a line from 24°N 145°W to 18°N 151°W.
Clear skies extends north of the islands to about 275 miles out. From that point on to the area of low pressure, is scattered to broken cumulus type clouds. Further east of the islands, east of the front, low clouds consist of the stable stratocumulus type, turning to cumulus type within 500 miles of the front.
Satellite imagery shows an area of clouds west of the main Hawaiian islands. These clouds are associated with cold front with the following coordinates, 33°N 171°W 26°N 174°W 21°N 180°E. This is about 900 miles west northwest of Kauai, moving east and southeast at 22 mph. The front goes further north to a low pressure system in the bearing sea. Cirrus clouds associated with this front extends to Kauai. Cumulonimbus and embedded thunderstorms with cloud tops above 30000 feet are detected north of 30°N.
