Hawaiian Islands Satellite Interpretation Message
Sat, 13 Nov 2010 06:30:00 -0600
Based on data through 1200 UTC November 13 2010.
Dense high clouds that have time to time blanketed the main Hawaiian islands the past couple of days have thinned somewhat. The bulk of the cirrus now cover the Big Island eastward with just a sliver still standing over the smaller islands. The partial clearing has allow us to view the low clouds situation around the main Hawaiian islands.
Judging from the latest satellite loop, low clouds coverage is scattered to broken over the Kauai channel and adjacent Kauai windward waters. Coverage becomes broken over the windward coastal waters from Oahu to the Big Island. The leeward waters of the smaller islands are scattered to broken. Weather radar shows a small batch of showers making its way onshore of windward Oahu. Scattered but light showers are also reaching windward Maui and Kauai.
The band of showers northeast of Maui and east of the Big Island earlier has undergone some dissipation but still hold a decent amount of showers as it presses on west and southward. The leading edge of this band is now a 100 miles northeast of Maui.
The second area of showers continues to pass well south of the Big Island. The area's northern fringe has brought some scattered showers to eastern Big Island especially the Puna district. The band of high clouds is obscuring the clouds and showers beneath.
The cirrus clouds are located to the right of the upper level trough axis, within 100 miles either side of a line from 14°N 167°W to 18°N 159°W to 18°N 152°W to 18°N 144°W. Also to the right of the upper level trough, an area of layered clouds with isolated thunderstorms within 120 miles either side of a line from 06°N 179°W to 11°N 172°W to 14°N 167°W. The upper level trough axis extends from 06°N 180°E to 16°N 170°W to 19°N 166°W to 21°N 160°W to 22°N 153°W to 23°N 143°W. A couple of thunderstorms are located immediately outside the cirrus and layered clouds.
Scattered moderate thunderstorms are detected between 800 and 1200 miles southeast of the Big Island, within 120 miles either side of a line from 08°N 154°W to 09°N 146°W to 14°N 133°W. The tops of the storms have touched 48000 feet. The area appears to be advancing northwestward slowly.
The leading edge of a cold front is 650 miles away from Kauai. Layered clouds with isolated thunderstorms are present within 120 mile either side of a line from 42°N 160°W to 35°N 165°W to 27°N 172°W. The front continues southwestward as a band of cumulus clouds, 80 miles either side of a line from 27°N 172°W to 22°N 177°W to 21°N 165°E.
