HONOLULU, Hawaii (HawaiiNewsNow) - High clouds will gradually thicken over the islands through early Thursday, while surface high pressure far north of the state maintains moderate trade winds with mainly windward showers.
Clouds and showers will increase statewide from late Thursday into Friday as a disturbance aloft passes overhead.
Drier weather is expected by this weekend, with a nighttime land breeze and afternoon sea breeze pattern. This may result in a few showers over interior sections of some of the islands each afternoon.
Trade winds will likely return early next week as a surface high builds north of the state.
A long-period north swell is expected to build Thursday into Friday, before turning to the north-northeast and increasing a bit further over the weekend.
The swell is expected to peak Friday through Saturday night, with advisory-level surf along north-facing shores, and warning levels for east-facing shores.
Advisory-level surf is possible with additional northwest swells Sunday night and into the first half of the new week.
