Based on data through 8:00 am Feb 28 2015 HST

Cloud cover over the main Hawaiian islands has changed little since late last night. Showery, broken to overcast low clouds cover the northeast half of Kauai, with scattered low clouds over the southwest half. Showery, scattered to broken low clouds upstream of Kauai are moving from slightly east of north around 15 mph. Broken to overcast layered clouds cover the area from Oahu southeastward. These clouds obscure most lower level features on satellite imagery. Isolated cumulonimbus cloud, CB, tops can be seen extending above the layered clouds within 200 miles east of the Big Island of Hawaii and within 50 miles of a line from 90 miles southwest of South Point to 17°N 164°W. A 150 mile wide band of showery broken to overcast low clouds and scattered towering cumulus clouds, TCU, is southeast of a line from the southwest edge of the layered clouds described above to 14°N 180°W.

A large area of broken to overcast low clouds is northwest of a line from 30°N 153°W to 26°N 156°W to 24°N 160°W to 17°N 170°W to 17°N 180°W. Most of these clouds are stable stratocumulus but there are showery broken to overcast low clouds, scattered TCU and isolated CB along the southeast edge of the area north of 25°N. There may be a surface low near 26°N 156°W. There are also showery broken low clouds northwest of a line from 30°N 158°W to 28°N 160°W to 24°N 170°W to 23°N 180°W.

The layered clouds over the main Hawaiian islands are part of a 450 mile wide band southeast of a line from 30°N 152°W, 680 miles north northeast of Molokai, over Oahu to 16°N 164°W, 500 miles southwest of Kauai. The cloud band is associated with a broad, deep trough aloft centered from a low aloft near 40°N 163°W to 30°N 164°W to 15°N 170°W. A strong jet stream runs from 20°N 180°W to 18°N 170°W over Oahu to 30°N 151°W.
