Looking Ahead

A nearby disturbance will keep the airmass over the islands rather unstable through Tuesday. Moisture riding in on the trades could be enhanced by this weather feature, with unsettled, wet trade wind weather continuing to be a possibility. The disturbance will weaken and move away by the middle of the week, leading to drier and more stable trade wind conditions.

Today

Occasional morning showers for windward spots with afternoon clearing. Leeward and Kau could get scattered afternoon showers with a chance of thunderstorms. Winds are increasing to 15 to 25 mph out of the northeast. High temperatures from 82° to 87°.

UV index at 12 (“extreme” exposure level)

Tonight

Northeast winds tonight around 15 mph or more. Mostly cloudy skies with scattered showers for windward spots tonight. Skies should clear as the night goes on for lee areas with scattered showers in the evening. Low temperatures from 70° to 75°.
