Hawaiian Islands Satellite Interpretation Message
Wed, 24 Nov 2010 06:30:00 -0600
Based on data through 1200 UTC November 24 2010.
Water vapor imagery shows the central Pacific dominated by an upper level ridge. The ridge axis extends from 38°N 155°W to 19°N 169°W and the effects cover an area from 30°N to 10°N and 140°W to 173°W. To the west of this ridge is an eastward moving deep upper level trough. A cold front is reflected at the surface along a line from 34°N 171°W to 22°N 173°E. The front and upper trough is producing a line of thunderstorms within a 400 mile wide band along the cold front line. The storms are traveling northeastward at 15 mph. The highest cloud tops are near 52 kft with these storms and have overall strengthened over the past six hours. A southwest to northeast oriented jet stream runs between the upper ridge and the upper trough.
With the upper ridge parked overhead, infrared satellite shows scattered to broken cumulus clouds around the main Hawaiian islands early this morning. Open-celled cumulus dominate over much of the windward waters while the leeward waters have plume clouds coming off mainly Maui and the Big Island. Land areas have cloud build ups mostly over windward and mauka areas. Radar is tracking scattered showers over windward sides of the islands and adjacent coastal waters. Many of the showers are concentrated across windward Big Island which become more disperse the further to the west.
Far south of the Hawaiian islands, relatively weak and widely scattered thunderstorms are present along the ITCZ with tops near 47 kft. Most of this activity is present between 06°N and 10°N.
