Partly cloudy skies are expected today. Light east winds are also expected from 5 to 15 mph. As the land heats up, sea breezes are expected to develop which will lead to afternoon cloud cover and possible isolated showers. Hazy skies are expected for parts of the Big Island (see UHSOEST vog model above), although it is not expected to be as hazy as the last few days. High temperatures should fall in the range of 81° to 86°.
