Hawaiian Islands Satellite Interpretation Message

Based on data through 0500 UTC December 30 2010.
To the northwest, a pair of nearly stationary cloud bands associated with fronts extended across Hawaiian waters. The more substantial band of deep layered clouds was located within 90 miles of the curve from 25°N 180 to 28°N 172°W to 30°N 167°W and further west and northeast. The fragmenting band of dissipating low to middle cloud layers was located within 60 miles of the curve from 18°N 177°W to 19°N 174°W to 21°N 174°W to 30°N 160°W and further northeast. Loosely packed cold-air cumuli prevailed between the northernmost band and 30°N.
To the south, there was little thunderstorm activity to mark an ITCZ. Layered low to middle debris clouds from earlier convection mostly obscured lower features between 10°N and 02°N. However, isolated thunderstorms and their deep layered debris clouds associated with a trough of low pressure occurred within the area bounded by the curve from 19°N 164°W to 14°N 159°W to 09°N 160°W to 05°N 168°W to 07°N 174°W TO15°N 166°W.
Thin layered high to middle cloud layers following a jet stream northeast from those thunderstorms, together with somewhat more substantial cloud layers forming in association with a weak trough of low pressure in the middle atmosphere, mostly to partly obscured lower features north of the curve from 30°N 161°W to 19°N 164°W to 19°N 157°W to 25°N 140°W.
Lower in the atmosphere, a layer of marine stratus moving in from the northeast broke up into fragments and bands of marine stratocumulus in the corner north of 10°N and east of 157°W. These clouds generally moved toward the west southwest at 15 to 20 miles an hour, and rose to heights of 6000 to 8000 feet, though a few taller cumuli along the southwest edge of this area approached 18000 feet.
Across the main Hawaiian waters, high to middle cloud layers partly obscured lower features. Where they were visible, lower clouds consisted mostly of daytime cumulus buildups over higher slopes inland, though a few marine cumuli also moved ashore along slopes facing east. Areas with the most cloud cover included central Kauai, southeast Oahu, east Molokai, the west Maui mountains, most middle slopes of Haleakala on Maui, and most lower to middle slopes of the Big Island. These lower clouds generally rose to heights of 5000 to 8000 feet. Radar data from near the islands showed scattered showers offshore well to the west of Kauai and southeast of the Big Island, but isolated showers at most elsewhere.
