Moisture will decrease through Monday. Light to moderate background trade winds will prevail, allowing sea breezes to develop in sheltered leeward areas. A brief increase in showers is expected Monday night, mainly on the Big Island, before we return to relatively dry trades through the end of next week. Wind speeds are forecast to increase from Friday into next weekend.
Light to moderate trades through the period. Low cigs and SHRA should primarily impact windward and mauka locations with some isol SHRA over leeward areas. MVFR conds possible in SHRA, otherwise VFR prevails.
AIRMET Sierra for mountain obscurations has recently been cancelled due to improving conditions across the state this morning. Afternoon clouds and showers over Kona slopes of the Big Island may cause mountain obscurations, but otherwise no AIRMETs are anticipated through today.

Moderate to fresh trade winds continue this weekend, though weaker winds will remain in place over the western waters as a trough lingers west of the area. Trade winds then decrease this upcoming week into the light to moderate range through much of the week with slight day to day fluctuations. Strengthening trades are possible towards the end of the week as high pressure builds north of the area.
A long-period south swell will peak today and hold through Monday, producing elevated surf along south and west-facing shores, but it will remain below advisory levels. South shore surf will decline gradually Tuesday into Wednesday, but a new long-period south swell arriving late Wednesday will provide another bump in surf for Thursday and Friday.
The short-period north-northwest swell generated by low pressure to the northwest of the islands will fade today, while a new small, long-period swell peaks. This will keep small surf continuing today for north-facing shores, but surf declines on Monday as this swell fades. Another small, long-period northwest swell is forecast to arrive on Monday and peak Tuesday, which will boost north shore surf back to moderate levels. A moderate north- northwest swell is possible by the end of the week, depending on the evolution of a projected low in the north Pacific. However, confidence is low given differences in model solutions with this feature.
Surf along east-facing shores will remain small as local winds remain fairly weak with only slight variations each day. Small, moderate-period west and east swells generated by multiple Pacific tropical cyclones continue to move through the islands through Monday.
None.
