Issued: Oct 01, 2014 2:30 PM HST

Based on data through 2:00 pm Oct 01 2014 HST

Low clouds crossing 140°W from the east Pacific are bringing scattered to broken skies as far west as 150°W. Low clouds are moving northwest between 20°N and 30°N and westward between 10°N to 20°N with an average speed of 15 mph. A cold front far north of Kauai is producing a 100-mile wide band of overcast clouds and thunderstorms from 30°N 156°W to 26°N 162°W. The band is moving 10 mph toward the east with thunderstorm tops reaching as high as 42 thousand feet. Behind the front layered low and mid level clouds cover the skies between 25°N and 30°N as far west as 175°W.

Aloft, an upper trough extends southwestward from 30°N 136°W to Hawaii to 17°N 170°W. The subtropical jet runs along the south side of this trough and is producing overcast cirrus south of 20°N with some high clouds approaching the Big Island.

Over Hawaii, interior areas have clouded up due to sea breeze convergence and daytime heating. Towering cumulus have formed over sections of the smaller islands bringing some locally heavy showers. Isolated CB's over Oahu have cloud tops reaching 40 thousand feet. Scattered low clouds over the coastal waters are moving toward the west northwest at 10 mph.
