Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 256 AM EDT Fri May 24 2024 Valid 00Z Sat May 25 2024 - 00Z Sat Jun 1 2024 Surface high pressure should generally be centered to the north and northeast of Hawaii for much of the upcoming week, and a slowly retrograding inverted surface trough coupled with a lingering upper level low west of the main populated Islands. Aloft, a broad upper level ridge axis is forecast to be in place and this should keep the trough away from the state. The models are in good overall agreement that the heavier rainfall associated with this disturbance should avoid most of the state, although the normal trade wind enhanced showers are expected to continue with east or east-southeasterly low level flow on most days. The guidance does indicate a gradual increase in precipitable water values going into the middle to end of next week, so this could result in an increase in showers. Hamrick
