Winds Statewide in a glance ...go HERE (this link is also the 4th drop down under weather)

Oct 01, 2014 4:00 AM HST

Watches/Warnings/Advisories
High surf advisory until 6 pm HST Thursday for south facing shores of all islands.

Synopsis
A more stable airmass is expected to return to the islands through the next few days, though light winds and muggy conditions will prevail as a weak surface high pressure ridge stays near the state.

Discussion
Mainly fair weather prevails over the islands early this morning, with isolated showers over the coastal waters. Early morning soundings from Lihue and Hilo still depict a rather unstable air mass, with little change in the moisture. Still expect to see less weather over the state through the next few days as air mass in the island vicinity will slowly become more stable. The overall synoptic surface weather pattern remains rather static in the island vicinity, as a weak high pressure ridge anchors just north of the islands at least through rest of the week. This will keep winds light in the island vicinity, allowing land and sea breezes to develop during night and day. Clouds will develop over the islands under day time heating. Since there will still be enough lingering moisture in the area, these clouds will probably bring measurable precipitation. Day time temperatures will also remain on the warm side and it may feel muggy due to the higher moisture. Showers will taper off in the evening, with clearing skies over the islands under night time cooling.

Latest forecast models still indicate the surface ridge may move south of the islands by early next week, as a surface front far northwest of the state is expected to advance more southeast. The ridge is expected to remain close enough to the islands to keep winds light. Therefore the current warm and muggy weather may persist through early next week.

Aviation
Isolated TCU will continue through the early morning across the coastal waters, which are expected to diminish after sunrise. Vfr conditions with mostly sunny skies prevail over the islands this morning. Expect to see clouds and showers building over the islands by this afternoon. Airmet sierra for mtn obsc may be necessary later today as these cloud build ups occur.

Marine
The current south swell remains high enough to bring advisory level surf heights to south facing shores today, as the readings from the near shore buoy just southwest of Oahu stay rather elevated. As such, a high surf advisory remains in effect for the south facing shores of all islands until Thursday. Also a northwest swell will peak today with below advisory levels surf for north and west facing shores. A series of moderate northwest swells will arrive during the weekend and possibly lasting through early next week.
