Increasing trades will keep showers focused over windward and mauka areas during the next several days. The southern portions of the aloha state will see more shower activity as a weak surface trough passes just to the south. The trough will strengthen just west of Kauai heading into the weekend. This will result in a return to southeasterly winds and an increased threat of unsettled weather over the western islands.
Today mostly cloudy skies are expected. Showers are likely for windward spots. Leeward spots will be mostly sunny to start with mostly cloudy skies and scattered showers in the afternoon. High temperatures from 82° to 87°. East winds are forecast around 15 to 20 mph.
UV index at 7 (“high” exposure level)
