    A slow moving cold front located about 200 miles northwest of Kauai is producing a 300 mile-wide cloud band between 17°N and 30°N from 160°W to 165°W. Embedded thunderstorms can be discerned within the cloud band about 150 miles west of Kauai along a line from 20°N 164°W to 30°N 160°W. Thunderstorm tops are reaching 45 thousand feet. The surface low associated with the front is centered over 28°N 167°W and is moving slowly toward the northeast. A swirl in the low level clouds discerns the position of the low. West of the low, between 170°W and the dateline from 20°N to 30°N, broken low clouds are moving south at 20 to 30 mph.

    East of the low and Hawaiian islands, low clouds are moving west at 15 to 25 mph propelled by high pressure centered near 35°N 145°W. Overcast low clouds dominate the area between 140°W and 150°W from 15°N to 30°N while scattered to broken low clouds cover the rest of the area east of 155°W to 140°W from 10°N to 30°N.

    The subtropical jet is advecting mid and high level moisture from the deep tropics and sending moisture in the form of high clouds over the Big Island and Maui county. The axis of the jet runs from 10°N 168°W then over the Big Island and continues to the northeast. Satellite derived cloud motion shows these high clouds are moving 70 to 90 mph toward the northeast.

    Over Hawaii, broken to overcast skies that formed from afternoon convection over the islands are slowly dissipating this evening. Thin cirrus continues to ride over the Big Island and Maui county.

    In the deep tropics, scattered moderate to strong thunderstorms are firing along the intertropical convergence zone between 140°W and 165°W from 01°N to 08°N, with scattered moderate thunderstorms found between 170°W and the dateline from 01°N to 10°N. Thunderstorm tops are reaching as high as 56 thousand feet.
