The two weak diffused fronts noted in the evening discussion are rather difficult to locate this hour. The front in the Kauai channel just east of Kauai is still there, which extended north through 30°N 152°W. Isolated towering cumulus clouds located at the northern portion of the front, mark the location of the front. The front ends in the vicinity of Kauai followed by a trough to 20°N 161°W. The front is moving very slowly eastward.
The second front is roughly 75 miles west of the first front with the coordinates of 30°N 155°W 24°N 160°W 20°N 170°W and 17°N 180°W. Portion of the front west of 170°W is nearly stationary, the rest of the front is moving southeast at around 10 mph. The front is seen as a rope cloud on satellite.
The low cloud picture over the islands has a large stationary patch with a few embedded showers extending from Oahu to Kauai county, and relatively clear skies elsewhere. A southerly wind flow has brought a few showers to Oahu, while a few showers are detected south of Kauai moving northward. Widely scattered low clouds are noted over the waters to the south of Lanai, and off the Kona coast and South Point. Clear skies controlled the waters up to 120 miles northeast and east of the Big Island. An extensive area of stable stratocumulus covered the area west of the second front.
Water vapor imagery shows a rather dry air mass but also an upper level trough west of Kauai with the axis from 30°N 161°W to 26°N 167°W to 20°N 177°W. The trough is moving towards the islands.
Deep convection is isolated if any in the tropics south of the islands.
