Hawaiian Islands Satellite Interpretation Message
Fri, 14 Jan 2011 06:30:00 -0600
Based on data through 1200 UTC January 14 2011.
Two cloud bands, both associated with unstable weather, were moving further away from the state early this Friday morning. One band, 180-200 miles wide and associated with a dissipating and departing front, had moved east of the Big Island. This broken to overcast layered cloud band was centered along a line through 30°N 144°W to 19°N 152°W. The west edge of this band was now about 80 miles east of the Big Island and it continued to drift slowly eastward. A few isolated thunderstorms remaining in this band were forming north of 25°N.
The second cloud band of similar width, was centered along a line from 30°N 152°W to 26°N 153°W to 24°N 158°W. This band contained mostly broken low clouds along its west edge with overcast layered clouds and scattered thunderstorms along the east half. Tops of the storms were near 38000 to 40000 feet. This band just north of the state was moving toward the northeast.
The Big Island was still mostly cloudy overnight. But the rest of the state saw dramatic decrease in cloudiness including over the surrounding waters. The patches of low clouds near the state were now clearly visible due to the exit of the higher clouds aloft. The low clouds near the Big Island were moving northwestward while the low clouds elsewhere around the state were flowing due north.
The next approaching front extended through 30°N 172°S to 26°N 180°E. Its associated low pressure system was centered near 33°N 179°E. The low and the front were moving east at 40 to 45 miles an hour. A large amount of broken to overcast cirrus clouds were spewing out ahead of the front, coming to within 215 miles northwest of Kauai this morning.
