Much of the aloha state and surrounding waters are blanketed by broken to overcast multilayered clouds associated with a front, whose leading edge appears to be over Maui county as of bulletin time. The cloudiness, and accompanying showers and steady rain, extends from west of Kauai to Maui and continues to spread eastward toward the Big Island. Most of the Big Island itself is covered by low and middle level wind-convergent clouds, though cloudiness not yet directly associated with the advancing boundary. For the moment anyway, skies are nearly clear immediately southeast clockwise through west of the Big Island over the adjacent waters. Based on radar wind profiles, low cloud motion is from the north to northwest near Kauai at 15 to 20 mph, and from the northwest to west near 15 mph from Oahu to Maui. Low level winds near the Big Island are transitioning from light south and southwest to light to moderate westerlies.
The front stretches far northeast and southwest from the islands, with most of the cloudiness currently west and northwest of a line from 30°N 142°W to a point over east Maui to 17°N 164°W. The back edge of the system is along a line from 30°N 152°W to 24°N 160°W to 19°N 169°W as of this writing. West of the front is a band of broken to overcast low clouds centered on a line from 22°N 163.5°W to 23°N 175°W to 24°N 180°.
Aloft above 25 thousand feet, the axis of a strong jet stream is roughly along a line from 34°N 180° to 30°N 168°W to 28°N 160°W to 30°N 150°W to 35°N 146°W. Its southern periphery is over and just north of the Hawaiian islands. These stronger winds have been particularly felt over the Volcano summits on the Big Island.
