The region will experience a slight shift in winds mid-week, but stable weather conditions are expected to remain in effect, with minimal moisture moving along the trade wind flow.
Therefore, shower activity will mostly be concentrated along windward areas, especially nocturnally, yielding light rainfall accumulations throughout the week.
Residents and visitors can expect predominantly drier conditions in leeward areas, with scattered afternoon showers occasionally along the Kona slopes of the Big Island.
The ongoing aviation forecast indicates stable, breezy trade winds providing ideal flying conditions across the region, although MVFR may arise during showers.
AIRMET Tango is currently in effect for low-level turbulence, cautioning aviators in the region.
In the marine forecast, high pressure north of Hawaii will drive persistent trade winds into the coming week, leading to a small craft advisory for several windier waters and channels.
Overall, the weather will showcase typical Hawaiian conditions, encouraging outdoor activities while remaining vigilant of rain-related changes.
