612 FXHW01 KWNH 050759 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 259 AM EST Wed Feb 05 2025 Valid 00Z Thu Feb 06 2025 - 00Z Thu Feb 13 2025 A weak ridge of high pressure at the surface will reduce easterly wind speeds Wednesday-Thursday, allowing some land/sea breezes to set up. Available moisture in the vicinity of the islands and a trough aloft could provide support for light to moderate showers, with the greatest coverage over Maui and the Big Island. Easterly trades should redevelop by Friday into the weekend and persist into early next week. This will favor possible showers across windward and mauka areas, but likely limited due to upper ridging and lack of moisture. Moisture may increase slightly at times Monday-Wednesday but this does not look too dramatic. Winds may veer in the western islands by Tuesday or Wednesday in response to a front or two northwest of the state. Tate $$
