Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 321 AM EDT Mon May 17 2021 Valid 00Z Tue May 18 2021 - 00Z Tue May 25 2021 Latest models and ensembles still agree that strong high pressure cells bridging to the north then northeast of the state will support brisk island trades for much of this week. Upper troughing to the northeast of the state through early week and lingering island moisture should support a mainly windward terrain/mountain shower focus pattern. Rainfall should be generally modest and moisture may gradually decrease the rest of the coming workweek, but there is an emerging guidance signal for a return of deeper tropical moisture and showers into the Big Island from the southeast by next weekend.
