Expect heavy rain with a slight chance of thunderstorms for the islands by Friday.
A cold front will approach and move into the area from the northwest by late Thursday.
Initially winds will become southeasterly and pre-frontal showers are possible especially for Kauai Thursday night.
By Friday the heavy rain moves into Kauai and Oahu during the course of the day.
Increasing moisture combined with a sufficient amount of instability and light winds ahead of this front will translate to warm and muggy conditions with increasing rain chances late Thursday through Saturday.
A few thunderstorms can’t be ruled out along and ahead of the front, especially over the northwest islands Thursday night into Friday.
A gradual drying trend from west to east with a return of moderate to breezy trades are expected by the end of the weekend and early next week as high pressure builds north of state.
