Scattered showers are expected for windward and mauka areas tonight. Leeward spots are forecasted to be partly cloudy with isolated showers in the evening, then clearing as the night goes on. Trade winds are forecasted from 15 to 25 mph. Low temperatures from 67° to 72° are expected.

 

Sunday

Partly cloudy skies are expected with scattered showers for windward and mauka locations, mainly in the morning and evening hours. The Kona side will have mostly sunny skies with isolated afternoon showers. Winds are forecasted out of the northeast from 15 to 25 mph strongest near Upolu Point and South Point. High temperatures from 81° to 86° and low temperatures from 67° to 72°.

 

Looking Ahead 

Fresh to locally strong trade winds are expected into the middle of next week. The trade winds will focus clouds and showers over windward slopes and coasts, but the atmosphere will become increasingly stable over the next couple of days. Therefore shower coverage should decrease this weekend, and remain minimal into early next week. Southeast winds may bring a wetter pattern toward the the second half of next week.
