162 FXHW01 KWNH 150713 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 212 AM EST Fri Nov 15 2024 Valid 00Z Sat Nov 16 2024 - 00Z Sat Nov 23 2024 The models agree well with a rather strong surface high situated to the northeast of Hawaii through Saturday, with a tight pressure gradient over the state and resulting in windy conditions with winds generally out of the east. The high should gradually weaken some going into Sunday, and the pressure gradient weakens going into the being of next week. The ensemble means differ some with a cold front north of the state, with the ECENS a little quicker to bring the boundary closer to the state by midweek. In any case, there will likely be a col in the subtropical surface ridge, and thus lighter winds going into the early to middle part of next week. In terms of precipitation prospects, there will likely be more trade wind based showers across the east-facing terrain through the weekend, especially across the Big Island. Other than that, not major heavy rainfall events appear likely over the next seven days. Hamrick $$
