    Looking Ahead

    High pressure across the Eastern Pacific and a trough in the Central Pacific will lead to a weak ridge north of the Hawaiian Islands through the weekend. Expect easterly trade winds for most islands with modified afternoon sea breezes along southern and western slopes of Kauai and Oahu through Sunday. Unsettled weather continues over the state next week, ahead of a stronger frontal system moving across the Central Pacific. Easterly trade winds will continue through Wednesday. Wind speeds will weaken and directions will veer towards the southeast by Wednesday night. Land and sea breezes will become more widespread on Thursday and Friday. Vog may move northward into the smaller islands by the end of next week.
