Hawaiian Islands Satellite Interpretation Message
Mon, 08 Nov 2010 18:30:00 -0600
Based on data through 0000 UTC November 09 2010.
A mid/upper level ridge is located to the northeast of the main Hawaiian islands. The water vapor loop shows an area of subsidence over the eastern half of the state associated with the ridge. Infrared satellite also shows a high reflected at the surface and centered at 32°N 143°W moving east at 20 mph over the last six hours. This high is pushing bands of broken cumulus clouds along it's southern flank from 130°W to 160°W. The cloud motions easterly at 25 mph.
Further to the west is an upper level trough and associated cold front. The upper trough runs along an axis from 40°N 172°W to 27°N 172°W. At the surface, the cold front runs from 39°N 154°W to 35°N 172°W to 27°N 178°W. A low has developed along the front near 35°N 172°W and a surface trough extends south of the low to 23°N 171°W. Strong thunderstorms are located around the low in an area from 28°N to 36°N and 167°W to 172°W with cloud tops to 48 kft. Lightning detection still continues to pick up on strikes in this area.
Around the main Hawaiian islands, visible satellite shows scattered cumulus clouds over windward coastal waters. Not a whole lot of cloud cover is seen over the leeward waters. Over land, scattered to broken cumulus clouds cover most of Kauai this afternoon. Oahu has broken cumulus clouds built up over the Koolau and windward side of the island, with a few clouds over the rest of the area. Molokai has clouds over the windward side of the island and is mostly sunny elsewhere. Lanai has cloud build ups over the central interior while the coasts remain sunny. Maui has clouds across the west Maui mountains along with the eastern and western slopes of Haleakala. The north and south slopes of Haleakala and the central interior remain mostly sunny. The Big Island has broken to overcast cloud cover over leeward slopes from Apua Point to South Point to Upolu Point up to 6 kft in elevation. Scattered clouds are observed over windward portions of the Big Island.
Elsewhere, widely scattered and unorganized convection is occurring far south of Hawaii along the ITCZ. Most of the activity is relatively weak and confined to an area between 05°N and 10°N across the central Pacific basin.
