Mostly cloudy skies are expected tonight with scattered showers for windward areas. Leeward spots will be cloudy to start and clearing is expected as the night goes on. Variable winds are forecasted up to 15 mph. Low temperatures from 67° to 73° are expected.
Cool and relatively dry northeasterly winds are expected to continue through Tuesday, with winds gradually weakening. These winds will carry low clouds and a few light showers over the islands, with the showers focusing along northeast facing slopes. The low clouds may spread to leeward areas on the smaller islands from time to time. Winds are expected to be light enough to allow land and sea breezes to develop from Wednesday into next weekend, with a somewhat cloudy and unsettled weather pattern expected.
