Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 252 AM EDT Thu Jul 29 2021 Valid 00Z Fri Jul 30 2021 - 00Z Fri Aug 06 2021 A preferred guidance composite indicates that high pressure building to the northeast of the state will support moderate to brisk island trades in a pattern favoring windward terrain rainfall. Remnant tropical moisture from a weakened disturbance slated to skirt to the south of the state may also fuel a bit more widespread showers today into Friday with an upper trough over/west of the state. Expect relatively drier air and upper ridge development over the islands in the wake of this system this weekend into next week. Schichtel
