Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 329 AM EDT Mon Mar 28 2022 Valid 00Z Tue Mar 29 2022 - 00Z Tue Apr 05 2022 A favored composite of reasonably compatible guidance from the latest models and ensembles indicates that weak upper troughing may provide some instability for shower activity across the islands into mid-late week in a pattern with light trades. High pressure set to re-establish to the north of the state may favor some deeper moisture transport into the southern islands as trades increasing return to brisker levels late week into next week. This may increase rainfall potential with a growing emphasis on favored Big Island windward terrain. Schichtel
