SATELLITE DISCUSSIONBased on data through 1800 UTC December 07 2016.
A deep trough cuts across the region roughly along 30°N 169°W, 24°N 170°W, and 11°N 180° and is traveling to the east around 20 mph. This feature is triggering isolated thunderstorms within 500 miles east of the trough axis north of 23°N, and also within 500 miles east of a westward drifting surface trough centered along 17°N 171°W and 10°N 175°W.
High clouds are streaming northeastward out of the southern area of thunderstorm activity and are increasing over the main Hawaiian islands, partially obscuring the low cloud features below. The first visible images of the day reveal locally broken low clouds piled up along windward slopes of all islands in a weak easterly low level flow. These low clouds are more extensive to the northeast of the Big Island, where a weak nearly stationary surface trough is lingering. The trough roughly lies along 21°N 155°W, 24°N 152°W, and 30°N 149°W.
Another weak surface trough is observed passing south of the Big Island along 18°N 156°W and 11°N 159°W. To the east of this trough and the trough near the Big Island lies a belt of trade winds.
