Hawaiian Islands Satellite Interpretation Message
Mon, 10 Jan 2011 18:30:00 -0600
Based on data through 0000 UTC January 11 2011.
A cold front had moved past Kauai near midday and was about to exit the Kauai channel and moved onto Oahu at 130 pm. The back edge of the accompanying cloud band was over Kauai with the west half of Kauai already in the clear. The east half of Kauai was still cloudy. The clouds along the frontal band were obscuring the entire area from east Kauai to the Big Island.
The cloudiness over the Big Island was mostly high level cirrus. However, numerous broken low clouds were seen flowing in beneath the high clouds from the south. These low clouds were streaming up from the south and veering toward the northeast as they neared the front.
The front itself extended south through 30°N 154°W to the west tip of Oahu to 20°N 162°W. Near the islands the front was moving toward the east-southeast at 20 to 25 miles an hour. Widely scattered thunderstorms were noted along the front from 23°N 157°W to 21°N 161°W and from 31°N 154°W to 27°N 155°W. Other isolated, weaker thunderstorms were embedded within the cirrus surrounding the state. The highest cloud tops associated with the thunderstorms were near 40000 feet.
An upper trough extended from a weak upper low to near 31°N 160°W to 20°N 166°W. Both were moving southeast at 30 to 35 miles.
