Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message
Mon, 06 Sep 2010 00:30:00 -0500

Based on data through 0500 UTC September 06 2010.

Light to moderate trade winds were carrying a few patches and small clusters of scattered to broken low clouds into the Hawaiian islands. These low based clouds were moving toward the west or slightly toward the west-southwest around 15 miles an hour. At 7 pm, most of the clouds were seen around the Big Island and along the windward sections of Maui.

An upper level low near 31°N 167°W was moving west at 10 to 15 miles an hour. A few wisps and strands of cirrus encircled this upper low. Another upper low near 23°N 178°W was nearly stationary. An upper trough extended down through 30°N 153°W to 27°N 156°W. The trough was drifting very slowly south while swinging southeastward.

Also in the upper levels of the atmosphere, a protrusion of scattered to broken cirrus clouds was headed toward Kauai from the southwest. The 275 miles wide finger of high clouds was centered from 17°N 174°W to 21°N 164°W. The high clouds were still about 275 miles from the garden isle.

Southeast of the state, a nearly stationary surface trough Sat from roughly 10°N 150°W to 13°N 140°W within the ITCZ. Isolated thunderstorms were embedded within 100 miles either side of the trough. Highest storm tops were near 47000 feet.
