Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message
Mon, 25 Oct 2010 19:30:00 -0500

Based on data through 0000 UTC October 26 2010.

An upper level low we have been tracking for several days now was centered about 250 miles west-southwest of Kauai and moving to the northwest at 15 mph. Counterclockwise flow around the low continued to bring high clouds up over the islands from the south. Most of the clouds were located between 20 to 30 thousand feet, and were wrapping around the low at 30 to 50 mph.

Upon close inspection, scattered to broken low clouds can be seen through thin spots and breaks in the high clouds. Because of the brisk trades, there was little difference in cloud cover upwind and downwind of the islands. The low clouds were moving to the west at 20 to 25 mph. Tops were at 6 to 7 thousand feet. Other than the high clouds, the low aloft had no effect on island weather.

The high clouds were being blown off the tops of scattered to broken thunderstorms, CB, located along the ITCZ. The ITCZ stretched from 140°W to 180°W between 07°N and 10°N. The greatest concentration of CB was between 143°W and 152°W, where CB tops were near 50 thousand feet.

Far to the northwest, layered clouds and embedded CB were observed northeast through east and south of a low centered near 28°N 179°W. The bulk of the clouds were northwest of a line from 30°N 160°W to 20°N 175°W to 16°N 180°W. Cb tops were 45 to 50 thousand feet. The low and area of clouds were nearly stationary.
