SATELLITE DISCUSSION

Based on data through 0500 UTC February 08 2016.

At 700 pm HST, satellite imagery showed the cold front that moved through the island chain over the past 24 hrs now east of the Big Island stretching south and southwest from 30°N 146°W to just east of the Big Island, then southwest to 14°N 162°W. Broken to overcast layered clouds were located north and northeast of 23°N along a cloud band associated with this front. Elsewhere, a band of mostly low- level cumulus clouds was depicted, which was beginning to break up and scatter out toward the southern end of the band or south and southeast of the Big Island. A gradual motion toward the east was depicted with this band over the past few hours.

Scattered low-level cumulus clouds were shown tracking south over the main Hawaiian islands in the wake of the aforementioned frontal boundary. However, broken to overcast patches of low clouds toward the back edge of the frontal cloud band continued to impact the islands from Maui to the Big Island, especially over the adjacent coastal waters north and east of Hana and the Hamakua coast. Cloud tops extended to 10 to 12 thousand feet with these clouds.

Scattered to broken cumulus clouds were depicted west of the previously discussed frontal boundary and north of the main Hawaiian islands between 25°N and 30°N from 149°W to 160°W. These clouds were tracking southeast at 30 to 40 mph. A few thunderstorms were depicted within this area near 30°N from 150°W to 155°W with cloud tops to 30 thousand feet.

Scattered to numerous thunderstorms were located well south of the state near and along the ITCZ between the equator and 6°N from 140°W to the date line. Debris or scattered high clouds associated with these storms were shown lifting northward and eastward between 7°N and 13°N. Maximum cloud tops associated with these storms extended to 58 thousand feet. A gradual motion toward the west was depicted.
