Hawaiian Islands Satellite Interpretation Message
Wed, 10 Nov 2010 12:30:00 -0600
Based on data through 1800 UTC November 10 2010.
A weak front extended roughly through 30°N 158°W to 26°N 167°W and continued southwest as a weak trough to near 20°N 173°W this morning. The front was nearly stationary as it Sat about 450 miles northwest of Kauai as was the trough. The associated cloud band consisted mostly of broken low and mid level clouds and broken to overcast high clouds.
Isolated thunderstorms were also occasionally popping up within the band. The highest storm tops, near 26°N 167°W, were up near 40000 feet. Water vapor imagery showed a weak upper level low near 26°N 167°W. The low was sliding south-southwestward within a northeast to southwest aligned upper trough from 30°N 167°W to 20°N 180°E.
A large swath of broken to overcast cirrus clouds was nearing the islands from the southwest. The northern edge of the high cloud mass stretched from 10°N 173°W to 21°N 160°W to 13°N 150°W. The cirrus was drifting northeastward toward the state. Strands of cirrus along the leading edge of the swath had just made it over Oahu and the west side of the Big Island.
Meanwhile, a few patches and small clusters of scattered to broken low clouds continued to traverse the island chain from the east. Most of these low clouds were noted along the windward or east side of the island chain from the Big Island to Oahu. Few low clouds were seen beneath the cirrus west of the state except for some broken low clouds over Niihau. At 8 am, the cloudiest skies were over Oahu, east Molokai, east Maui and the windward sections of the Big Island. The low clouds near the islands were moving mainly west near 20 miles an hour.
