Hawaiian Islands Satellite Interpretation Message

Hawaiian Islands Satellite Interpretation Message

Based on data through 1800 UTC February 27 2015.
Posted: February 27, 2015, 6:30 pm

A weakening front was lying across Oahu this morning. This frontal boundary stretched through 30°N 158°W to weak surface low near 26°N 158°W to 24°N 157°W across Oahu to near 19°N 163°W. Isolated thunderstorms were firing up along the front between 23°N and 30°N. Much small and brief thunderstorms were forming along the front from 20°N to 23°N.

The associated frontal cloud band was very narrow south of 25°N latitude. And the clouds within it were fairly fragmented and mostly broken low to mid level clouds with some cirrus occasionally flowing over it. That part of the frontal band north of 25°N consisted of overcast cloud layers with tops, mainly from the thunderstorms, up near 40000 feet. The front was nearly stationary. The weak low was drifting slowly northeastward.

A stable air mass also resided in the area just east of the front, from 23°N to 30°N between the front and 150°W longitude. Clusters of broken layered clouds and a few isolated thunderstorms were noted in this area. These clouds were flowing northward.

Another front was seen well northwest of the state, stretching through 30°N 175°W to 28°N 180°E, and continuing west to 28°N 173°E. That front was fairly weak. That part of the front along 30°N was moving east near 30 miles an hour. Along 180°E, the front was stationary. The frontal band consisted of broken to overcast low clouds south of 30°N.

Water vapor imagery showed a large upper level trough extending southeast from an upper low near 42°N 172°W to near or just north of Kauai. The trough was moving slowly east and keeping the air mass over the state unstable.

At 8 am, skies were cloudy to mostly cloudy over Oahu and over much of the Kaiwi Channel to west Molokai. Kauai and the South Point area of the Big Island had some small clusters of broken to overcast low clouds overhead except for clear skies on the east side. East Maui had some patches of scattered to broken low clouds. The rest of the state was sunny to mostly sunny.
