Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 345 AM EDT Tue Jun 13 2023 Valid 00Z Wed Jun 14 2023 - 00Z Wed Jun 21 2023 The core of the subtropical high is expected to be nearly anchored in place around 35N/145W through the upcoming week, and the Islands will be on the southwestern periphery of this high. The GEFS mean is slightly closer to the state with the high compared to the ECENS mean by Saturday and beyond. This will also be co-located with a building upper level high in the same general region. There will likely be a weak upper level trough that tracks slowly northwestward through the end of the week, but except for some slightly heavier showers across the Big Island, it should not have a noticeable effect on the local weather for most locations. In terms of sensible weather, low level trades should generally be out of the east with some occasional ESE component at times, with moderate flow velocities expected. No major surges of tropical moisture are expected over the next week. Hamrick
