The windward side is forecasted to get mostly cloudy skies and frequent showers. Leeward spots are expected to get scattered showers. East winds are forecasted around 15 mph. Low temperatures from 67° to 72° are expected. Snow showers are possible on our summits.
Showers carried by the trades are expected to favor windward and mauka areas. Trade wind speeds are forecasted to weaken slightly on Friday. An increase in showers is expected Friday and Saturday due to an area of enhanced tropical moisture spreading up from the southeast over the eastern end of the main Hawaiian Island chain. Snow showers are possible on our highest summits from Friday night into Saturday. Drier and breezier conditions are forecast to return early next week as a surface high strengthens to the northeast of the islands.
