Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 340 AM EDT Tue Sep 10 2024 Valid 00Z Wed Sep 11 2024 - 00Z Wed Sep 18 2024 The latest ensemble means are in good agreement that the upper low currently northeast of the Islands will slowly drift to the west over the next few days, and then slowly dissipate. The meandering weak frontal boundary over the central and northern Islands should also slowly drift back to the west through the middle to end of the week. The surface high then builds back to the north of the Islands. In terms of sensible weather, generally lighter and more variable flow for the first half of the week can be expected with the col in place and the frontal boundary nearby. A more steady easterly flow resumes by the end of the week with the surface high rebuilding north of the state. The mainly terrain favored showers can be expected most days, but no major rainfall events are currently anticipated over the upcoming week with the deepest tropical moisture remaining well to the south, although there may be some resurgence of higher PWs by next Tuesday.
