Issued: Jul 05, 2015 2:30 AM HST

Based on data through 2:00 am Jul 05 2015 HST

Infrared satellite imagery showed a narrow band of broken to overcast cumulus and stratocumulus clouds, about 90 miles wide, extending along a cold front boundary far NW of Kauai. This band was stretching from 30.0°N 167.8°W to 24.1°N 177.9°W while migrating to the ESE at about 20 mph, with cloud tops ranging from 10 to 13 thousand feet.

Closer to the island chain, mainly scattered low clouds prevailed over the Big Island except for patches of broken coverage over windward areas from Kapoho to Pepeekeo. On Maui county, broken low clouds lingered over the W Maui mountains and along coastal locations from nahiku to huelo. The rest of the county remained under scattered low clouds or mostly clear. On Oahu, broken low clouds covered the ridges of the Koolau mountains, and portions of the Waianae range. The rest of Oahu remained under scattered low clouds. On Kauai county, patches of broken low clouds were observed over interior Kauai, while the rest of that island remained mostly clear.

Elsewhere, scattered to locally broken cumulus and stratocumulus clouds prevailed across the area N of 10°N with low cloud motion mainly to the W at 15 mph from 140.0°W to 158.0°W. Low cloud motion then shifted to a more nw/n flow between 158.0°W and the aforementioned cold front boundary, then turning to the SE behind the front.

Far S of the islands, .deep convection along the intertropical convergence zone, or ITCZ, is still producing broken layered and cirrus clouds across the area from 02.0°N to 14.0°N and 140.0°W to 170.0°W. A large cluster of thunderstorms was centered around 07.6°N 163.8°W, or about 970 miles SW of Oahu. Another cluster of thunderstorms was centered around 09.3°N 151.6°W, or about 760 miles SE of the Big Island. Highest cloud tops in these thunderstorms were between 48 to 52 thousand feet.
