Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 338 AM EDT Mon Sep 04 2023 Valid 00Z Tue Sep 05 2023 - 00Z Tue Sep 12 2023 Models and ensembles reasonably agree that height falls and general upper troughing will shift gradually westward over the state and vicinity through the next couple of days in a pattern with disrupted island trades and land/sea breezes, but below normal moisture will limit shower activity. A guidance composite is preferred to mitigate smaller scale differences consistent with predictability. Trades may be slow to return through next weekend. However, deeper tropical moisture may reach/skirt the southern islands in the Tuesday-Thursday timeframe and there is a growing signal this may fuel some localized downpours, mainly over the Big Island. Otherwise, expect slow to rise heights in the wake of upper trough passage into late week and next weekend and a return to below normal moisture availability and shower activity. Schichtel
