Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 357 AM EDT Wed Sep 18 2024 Valid 00Z Thu Sep 19 2024 - 00Z Thu Sep 26 2024 Over the next several days, generally typical trade wind weather is forecast over Hawaii. This will include moderate to breezy easterly trades with minor variations in strength from day to day, depending on the strength and position of the typical high located well north of Hawaii. Some showers will favor windward/mauka areas but there does not look to be any widespread heavy rain through the rest of the week into the weekend. Into early next week, a mid-upper low will be overhead of the state, which may raise the inversion for more showers. The GFS in particular shows increased moisture coming in Tuesday-Wednesday, but most models stay on the drier side for environmental moisture. Regardless, will continue to monitor. Tate
