Trade winds will ease slightly today, then remain at mostly moderate speeds through the rest of the week. Bands of low clouds and showers will periodically push across the islands, focusing primarily over windward and mountain areas during the overnight and early morning hours. A couple bands of enhanced moisture will move through the islands tonight through Thursday morning, bringing an increase in shower coverage and intensity, with some locally heavy rainfall possible. In addition, humidity levels will rise, making the first half of the work week feel rather muggy across the island chain.
Moderate to locally breezy trades are expected through Monday. Low clouds and scattered showers will move over primarily windward and mauka areas, making for intermittent MVFR conditions. Otherwise VFR conditions are expected.
A small area of low pressure is approaching Big Island this afternoon and may increase shower coverage and strength from roughly 3 PM HST to midnight.
AIRMET Tango is in effect for moderate turbulence downwind of terrain due to breezy trade winds and will continue through the forecast period.
