Looking Ahead

A rather humid airmass is in place due to a weak trough of low pressure near Kauai. Showers and a slight chance of thunderstorms are in the forecast for portions of the state today. A drier airmass along with strengthening trade winds are in the forecast for Monday and Tuesday. For the remainder of the week, the forecast will be highly dependent on the track and intensity of Hurricane Lane. An increase in trade winds and shower activity will be the likely result based on the latest forecast for Lane.
