616 FXHW01 KWNH 240750 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 250 AM EST Sun Nov 24 2024 Valid 00Z Mon Nov 25 2024 - 00Z Mon Dec 02 2024 Light winds on Sunday are forecast to turn northward (but remain light) as a weak front comes across Kauai Sunday night and moves southward Monday-Tuesday as it dissipates. Some weak moisture convergence along/ahead of the front and slightly moistening PWs could lead to a band of showers in the western islands Sunday night per the HREF, but with no widespread heavy amounts. Farther east, some light showers are possible across eastern parts of the Big Island. By Tuesday or Wednesday a weak surface ridge is forecast to set up north of the state, causing winds to veer toward the east-northeast. Generally dry conditions are likely to continue, but any showers that do develop would favor windward and mountain areas. Moisture should become even more suppressed by Thursday-Friday as a mid-upper high comes overhead. Trades may relax again by next weekend, but it remains uncertain to what extent the trades weaken.
