Looking Ahead
A gradual improvement in our weather pattern from west to east is expected over the next few days, as moisture associated with a trough of low pressure moves off to the northeast. Weak high pressure will build in to our north with light northeast trade winds filling in beginning on Monday. Another round of unsettled weather is forecast for later in the week as another trough of low pressure comes near the Hawaiian islands.
Today
Partly sunny skies are expected with chance of showers for windward spots. Kona side is expected to be sunny in the morning with some clouds building in the afternoon. Keep in mind a disturbance that was affecting Maui County last night is expected to dissipate over parts of the northwest coast this morning. Once that clears, conditions will clear up. High temperatures from 78° to 83°. Winds will be variable up to 15 mph.
