Water vapor imagery showed a relatively weak upper low near 29°N 154°W. A fairly shallow upper trough extended from the low to near 24°N 159°W. The low and trough were drifting slowly toward the east southeast. A handful of isolated, short lived type thunderstorms had been popping up recently within mainly within 250 miles northeast and east of the low.
Upper level winds from the southwest were carrying a few strands of broken cirrus clouds across mainly the southeast half of the island chain. One of the larger strands, which was only about 75 miles wide, Sat south of the Big Island and was centered along a line from 16°N 156°W to 20°N 150°W to 21°N 142°W.
Few low clouds were noted in the immediate vicinity of the Hawaiian islands this afternoon. Prevailing trade winds were currently carrying only isolated patches of scattered low clouds through the area. The clouds were moving west around 20 miles an hour.
At 2 pm, skies were mostly cloudy to cloudy over the slopes on the west half of the Big Island. Mostly cloudy skies were seen over the Hilo and Puna districts on the east side. It was mostly sunny over the interior sections of the Big Island. The other islands had only a smattering of scattered to broken low cloud patches mainly over the slopes. Thus skies were mostly sunny from Kauai to Maui including the vast majority of the nearby surrounding coastal waters.
A few very weak low pressure areas were strung out and embedded within an elongated mass of clouds and thunderstorms lining the tropics between 140°W and the dateline. This mass of unstable weather was within a 400 to 500 miles wide area centered along a line from 12°N 140°W to 11°N 160°W to 04°N 180°E. The remnant of former tropical depression Genevieve was now barely discernible somewhere around 675 miles southeast of Hilo.
