Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message

Based on data through 0500 UTC December 08 2016.
Posted: December 8, 2016, 5:30 am

At 700 pm HST, water vapor imagery showed an amplified upper pattern across the discussion area that was characterized with an upper trough extending south between Kauai and the date line and an upper ridge axis extending north-northeast between the Big Island and 140°W. Mid to upper southwest flow east of this upper trough was drawing a large plume of moisture northeastward from the deep tropics across the main Hawaiian islands to 30°N 145°W. This moisture combined with the upper trough and a weak surface trough near and northeast of the Big Island continued to support a large shield of broken to overcast layered clouds extending northeast from around 10°N 170°W to the Big Island to 30°N 145°W and beyond. A few thunderstorms were developing a few hundred miles south-southwest of Oahu that were tracking northeastward. A band of thunderstorms associated with low pressure near 30°N 165°W was located on the back edge of this large area of clouds that extended southwest from 30°N 160°W to around 250 miles northwest of Kauai. Maximum cloud tops associated with these storms extended to around 40 thousand feet. Mostly cloudy to overcast conditions prevailed over the islands due to this large shield of clouds. The back edge of this cloud coverage was a few hundred miles west of Kauai. The upper trough supporting this cloud coverage was slowly moving toward the east-northeast.

Scattered to broken layered clouds, mostly upper clouds, were shown advancing eastward over Midway island ahead of the next frontal system approaching. Elsewhere, a few thunderstorms were developing occasionally across the deep tropics several hundred miles south-southeast of the Big Island. These storms were tracking toward the west. Maximum tops extended to around 40 thousand feet.
