Hawaiian Islands Satellite Interpretation Message
Sun, 09 Jan 2011 18:30:00 -0600
Based on data through 0000 UTC January 10 2011.
Extended satellite loops reveal a change in low cloud motions near the islands over the past several hours, with this morning's light westerly flow transitioning to an increasing southwest flow this afternoon. Cloud cover over the islands, although somewhat increased from this morning, remains rather minimal, with mostly sunny skies the rule this afternoon.
On Kauai, scattered to locally broken stable stratocumulus /sc/ are over the lower interior slopes facing southwest, and over the lower slopes over the northeastern part of the island. Practically all coastal areas are cloud free. On Oahu, the northeastern lower slopes of the island have scattered to broken sc, with the remainder of the island under sunny skies. Molokai is sunny, as are Lanai and west Maui, but the lower slopes of Haleakala have a ring of stable scattered to broken sc, with the greatest cloud cover over the south facing slopes. The summit of Haleakala is sunny. The leeward side of the Big Island is sunny, as are the summits, where the snow is clearly seen, but is not as apparent as it was at this time yesterday. The lower slopes along the northeast side of the island have broken to locally overcast low clouds, from Hakalau to Paauilo. Few stable low clouds are over most of the near shore waters, except for scattered to locally broken sc over the waters south and west of Niihau. Low clouds are now moving toward the northeast near 10 mph near Kauai and Oahu, with their forward motion a little slower near Maui and the Big Island.
A deep-layered low centered about 850 miles northeast of the Big Island had been influencing the low level flow near the islands over the past 24 hours, but it is now distancing itself from the islands. A front approaching from the northwest is now beginning to exert it's influence on the low level flow over the islands, with the leading edge of the front about 600 miles west-northwest of Kauai. The front has been moving toward the east and southeast at 30 to 35 mph over the past 6 hours. A northeast to southwest band of clouds, showers, and isolated thunderstorms that lies between the front and the islands has increased in coverage since this morning, merges with the frontal band north of 25°N near 168°W. This band of pre-frontal convergence becomes increasingly separated from the front southwest of 25°N, and extends as far south as 16°N.
