A nearly stationary front lies 700 miles northwest of Kauai and stretches NE to SW from 30°N 165°W to 21°N and the dateline. The front is producing a 150-mile wide band of layered clouds with embedded thunderstorms. Thunderstorm tops are reaching up to 40 thousand feet.
An upper level low is spinning 600 miles southwest of Kauai and is producing a shield of mid and high clouds over the northeast quadrant of the circulation, between 17°N and 22°N from 163°W to 168°W. Isolated thunderstorms are forming near the center of the low at 18°N 168°W.
An extended band of low clouds is moving eastward in the trade winds and runs from the Big Island to 20°N 150°W to 24°N 140°W and into the east Pacific. This band is 150 miles across with overcast low clouds and embedded showers. North of this band to 30°N, broken low clouds are moving 15 to 20 mph toward the west until 155°W. West of 155°W, low clouds turn toward the northwest into the aforementioned frontal boundary.
Across Hawaii, a band of low clouds is bringing clouds and showers to windward coasts and slopes while leeward locations have partly cloudy skies.
